Littelfuse's TPSMB-VR series transient voltage suppression (TVS) diode provides secondary protection of sensitive automotive and other electronics from transients induced by load dump and other transient voltage events. The TPSMB-VR series complies with the automotive electronics council's Q101 stress test qualification for automotive-grade discrete semiconductors (AEC-Q101 qualified). It is ideal for protecting I/O interfaces, VCC bus, and other vulnerable circuits used in automotive applications. TPSMB-VR series has varying breakdown voltages ratings than its sister series, TPSMB, providing additional protection ratings.
