Taiwan Semiconductor, a global supplier of discrete power electronics devices, LED drivers, analog ICs and ESD protection devices, announces its new line of automotive-qualified rectifiers featuring ESD withstand capability. The new TSD Series rectifiers simultaneously provide repetitive peak reverse voltage of up to 600 V as well as ESD protection of >10,000 V (per IEC-61000-4-2). Devices in the series have optional current ratings of 1 A, 2 A, and 3 A and operating temperature ranges from -40°C to ±175°C. All have a maximum forward voltage drop of 1.1 V and feature low-reverse leakage current and fast response time. 

Qualified to automotive standards, the TSD Series offers superior protection in a range of applications. These include input polarity protection where DC input voltage is applied; bridge and general purpose rectification circuits; LED strings and POE I/O protection, ESD protection, clamping, snubber networks, and transient protection for datacom systems. They also provide reliable protection for smoke detectors, industrial controls, security systems, communication systems, lighting, and other systems that depend on continuous operation.

“Typical rectifiers are limited to ESD capability of less than 1.5kV and cannot meet industry standards for ESD protection required by IEC-61000-4-2 contact mode,” said Sam Wang, vice president, TSC Products. “Also, ESD will punch through standard polarity-protection rectifiers, resulting in failure modes that can immediately damage the TVS—or else create "walking wounded" damage that later manifests as failure during normal operation. In contrast, our ESD-capable TSD Series devices were developed to survive and protect customers’ end equipment now and in the future.”
