Thank you, Brett, and good afternoon. Looking more closely at third quarter revenue, POS revenue was up driven by strong demand in Asia. Distributor inventory in terms of weeks was down in the quarter and within our normal range of 11 to 14 weeks, which is where we expect it to remain near term. Global sales for the third quarter: Asia represented 74% of revenue; Europe, 17%; and North America, 9%. In terms of our end markets, industrial was once again our largest representative end market at 28% of revenue; consumer, 24%; communication, 22%; computing, 16%; and automotive, 10% of revenue.
Now let me review the end markets in greater details. Starting with our automotive market, revenue reached another record as we continue to gain increasing traction and content in this key focus area for Diodes. We also expanded our product portfolio by introducing exciting new products for multiple product lines, including MOSFET, crystals, LED drivers, TVS, Zener diodes, protection products, bipolar junction transistors, SBR and sensors.
Diodes also recently released our XRQ family of crystal qualified to AEC-Q 200 Grade 1 requirements targeting auto applications that demand frequency accuracy under harsh environments. Additionally, Diodes' leading PCI Express 4.0 solution and USB Type-C solutions for signal muxing and signal integrity continued to see growth in emerging automotive applications like instrument cluster, infotainment and assisted driving information. In fact, PCI Express has become the interface of choice for the backbone transmission of engine control unit, ADAS, navigation, telematic and infotainment systems. Diodes is well positioned to address this need with a variety of products designed to support the PCI Express protocol. Diodes is the only supplier to offer PCI Express 4.0 Clock Generators and Clock Buffers with AECQ Grade 2 105 C ambient temperature support.
Also in the automotive market, we continue to see success with our proprietary SBR technology as well as MOSFET design-ins. These products are suitable for a wide range of applications in connected driving; ADAS; telematic and infotainment; powertrain, covering conventional hybrid and electric vehicles; and battery management system. In addition, we saw new design wins for our gate driver ICs for in-car charging system for portable equipment such as phones and tablets. We also saw growth in our TVS product in cameras and ADAS system and for our multichip array products using engine diagnostic test systems. Diodes also have multiple design wins and revenue growth from our newly introduced LED driver in rear light and air filter applications.
In our largest representative end market of industrial, our momentum continued with new design win activities across many applications such as metering, DC fans, power tools and power supply as well as home appliances, including e-lock applications. Our glass passivation process rectifier and bridge rectifier product experienced strong growth in applications, including pumps, mixers, aeration system and measurement system. In the third quarter, revenue increased for our linear mode discrete LED drivers in various commercial and industrial lighting applications. Bipolar transistors also continued to be in demand for industrial applications where they are often used for voltage regulation and driving the gates of power devices such as MOSFET and IGBT.
Additionally, we continue to expand our market position in industrial PC by expanding design-in activities with our low-power PCI Express 2.0 switch. Our product's low-power performance gives Diodes a leading position in the small-lane and port expansion applications. We are also seeing USB Type-C adoption into medical equipment with our HDMI over the Type-C crossbar switch design-in for transporting video image to monitor over a USB Type-C interface. Diodes also introduced during the quarter our universal high-speed crossbar switch that supports the latest protocols such as PCI Express 4.0, Thunderbolt 3, SuperSpeed USB 20-gigabit per second and 10 GBase-KR. It provides an almost universal solution to routing high-speed signals up to 20 gigs per second. Further, with the rapid adoption of high-speed interfaces across multiple end applications in the IoT industry, ESC protection is becoming more and more important for such data links. Multiple design wins in third quarter confirm Diodes' leading position in the ESC protection devices.
Turning to consumer. This market continues to be a strong area for Diodes' SBR Schottky and GPP rectifier, growing both sequentially and year-over-year. We saw increased momentum for new applications like smart speakers, wireless chargers, gaming PC power, white goods, protection circuit modules for reverse polarity protection and IP phone market. Low-leakage CSP products are increasingly used in the battery pack for portable devices to boost battery life. Also in the quarter, Diodes' protection product continued to gain traction in various panel applications such as mobile panels, TV panels, monitor panels and notebook panels.
In the communication market, as reported last quarter, we continue to see design win expansion of our products in the 5G applications like CPE, small cell, base station, baseband units and remote radio units for higher speed, increased bandwidth and improved power density. We also saw additional design wins in 5G applications for discrete, power management, clocks and connectivity products, including USB ReDrivers and switches. Power density is one of the key concerns for 5G smartphones, and Diodes has been actively engaged in this market with our comprehensive small footprint DFN and CSP MOSFET portfolio. Also in the communication market, we continue to see revenue growth from mobile handset applications for our products like high-tolerance Zener diodes, high-voltage fast-switching diodes, low-leakage to no diodes and fast-recovering GPP rectifier. In addition, our protection products continue to be our key growth area driven by USB Type-C adoption in mobile phone applications.
Lastly, in the computing market, revenue grew in notebook/PC applications for our TVS products, high-current LDOs, high-tolerance Zener diodes, rectifier and small signal fast-switching diodes. Our signal integrity solutions continue to maintain a leadership position as they are well recognized by CPU partners. With adoption of USB Type-C in notebook and PC applications, we are seeing this area as the next big growth engine for protection and connectivity products from our Pericom product line.
Speaking of our Pericom IC product line, as Dr. Lu mentioned in his comments, we once again achieved another quarter of record revenue from this product, which is a testament to Diodes' ability to leverage our global sales channel and cross-selling opportunities we have been able to achieve across our customer base. We also achieved strong revenue growth for low switches in PC and mobile applications combined with increasing design wins for our high breakdown voltage products for our applications such as power over Ethernet, server power and data center.
In summary, our achievements of record results in the third quarter is a further testament to Diodes' consistent execution and the increasing benefit from our total solution sales approach and content expansion at key customers. Further, as indicated by our fourth quarter guidance, we expect full year revenue to grow 2.8% over 2018, which is further evidence of our continuous outperformance of our served markets. We look forward to the additional opportunities afforded by the proposed acquisition of Lite-On Semiconductor in terms of broadened product offering as well as wafer and packaging capacity to further support our future growth.
With that, we'll now open the floor to questions. Operator?
