11 August 2025 — Recently, Vishay Intertechnology, Inc. introduced its new TVS diodes — the T15BxxA and T15BxxCA series. To meet the demands of automotive applications, Vishay General Semiconductor's T15BxxA and T15BxxCA series have been certified to AEC-Q101 standards and can operate at high temperatures up to +185°C.

Compared to transient voltage suppressors (TVS) using SMC (DO-214AB) packaging, the newly released automotive-grade devices are 58% smaller in size, thereby saving board space and reducing system costs. The unidirectional T15BxxA series offers extremely stable breakdown voltages ranging from 12 V to 51 V, while the bidirectional T15BxxCA series provides breakdown voltages from 12 V to 100 V. These devices feature excellent clamping capability (17.0 V to 70.1 V for T15BxxA and 17.0 V to 137 V for T15BxxCA) and extremely fast response times.

TVS devices are designed to protect sensitive electronic equipment from voltage transients caused by inductive load switching and lightning strikes. Typical applications include lighting, electromechanical brakes (EMB), and fuel pump control; 48 V DC/DC converters and inverters; starter/generator units, battery management systems (BMS), vehicle control units (VCU), and onboard chargers; and telematics control units (TCU) for audio, electronic stability control (ESC), and radar sensors.

These devices meet the J-STD-020 MSL Level 1 standard, comply with RoHS standards, and are halogen-free.

Single/bidirectional TVS devices are now available for sampling and are in mass production, with a lead time of 12 weeks.
