Uni/bidirectional TVS solutions offer high temperature operation in SMB package

Vishay Intertechnology, Inc. has introduced a new series of uni/bidirectional 1500W surface-mount PAR TVS in the SMB (DO-214AA) package. To satisfy the demands of automotive applications, the Vishay General Semiconductor T15BxxA and T15BxxCA series are AEC-Q101 qualified and deliver high temperature operation to +185C.

Compared to TVS in the SMC (DO-214AB) package, the automotive grade devices provide a 58% smaller footprint to save board space and lower system costs. The unidirectional T15BxxA series provides extremely stable breakdown voltages from 12V to 51V, while the bidirectional T15BxxCA series offers breakdown voltages from 12V to 100V. The devices provide exceptional clamping capability – 17V to 70.1V for the T15BxxA and 17V to 137V for the T15BxxCA – and very fast response times.

The TVS are designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. Typical applications will include lighting, electro-mechanical brake (EMB), and fuel pump control; 48V DC-DC converters and inverters; integrated starter generators, BMS, VCU, and onboard chargers; and telematics control units (TCU) for audio, ESC, and radar sensors.

The devices meet MSL level 1 standards per J-STD-020 and are RoHS-compliant and halogen-free.
