Vishay Intertechnology Inc. (NYSE: VSH) has launched a new series of high-temperature, surface-mount transient voltage suppressors (TVS) designed for automotive electronics. The T15BxxA (unidirectional) and T15BxxCA (bidirectional) series operate at temperatures up to +185 °C and come in a compact SMB (DO-214AA) package.
The new devices are AEC-Q101 qualified, making them suitable for harsh automotive environments. Compared to larger SMC (DO-214AB) devices, these models offer a 58% smaller footprint, enabling greater board space efficiency and reduced system costs—especially important for electric and hybrid vehicle platforms.
The unidirectional TVS series supports breakdown voltages from 12 V to 51 V, while the bidirectional series ranges from 12 V to 100 V. Both offer strong clamping performance—up to 70.1 V for unidirectional and up to 137 V for bidirectional—along with fast response times to protect sensitive electronics from voltage transients caused by inductive load switching and lightning.
Target applications include lighting systems, electro-mechanical braking (EMB), fuel pump control, 48 V DC/DC converters and inverters, battery management systems (BMS), vehicle control units (VCU), and on-board chargers. The devices are also well-suited for telematics control units supporting radar, audio, and electronic stability control (ESC) features.
Vishay’s new TVS solutions comply with MSL level 1 per J-STD-020 and are both RoHS-compliant and halogen-free, meeting current industry environmental standards.
Samples and production quantities are available now, with standard lead times of 12 weeks.
