MALVERN, Pa. — Vishay Intertechnology has introduced a new series of uni/bidirectional 1500 W surface-mount PAR® transient voltage suppressors (TVS) in the SMB (DO-214AA) package. To meet the demands of automotive applications, the Vishay General Semiconductor T15BxxA and T15BxxCA series are AEC-Q101 qualified and offer high temperature operation to +185 °C.
Compared to TVS in the SMC (DO-214AB) package, the Automotive Grade devices released today provide a 58 % smaller footprint to save board space and lower system costs. The unidirectional T15BxxA series offers extremely stable breakdown voltages from 12 V to 51 V, while the bidirectional T15BxxCA series provides breakdown voltages from 12V to 100 V. The devices offer excellent clamping capability — 17.0 V to 70.1 V for the T15BxxA and 17.0 V to 137 V 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; 48 V DC/DC converters and inverters; integrated starter generators, BMS, vehicle control units (VCU), and on-board chargers; and telematics control units (TCU) for audio, electronic stability control (ESC), and radar sensors.
The devices meet MSL level 1 standards per J-STD-020 and are RoHS-compliant and halogen-free.
Samples and production quantities of the uni/bidirectional TVS are available now, with lead times of 12 weeks.
