This is the under-hood temperature band, with an operating junction range of -65°C to 150°C. ## Breakdown and clamping thresholds The minimum breakdown voltage is 22.8V, so the diode starts conducting and clamping the transient once the line voltage exceeds that level. This limits the voltage spike seen by downstream electronics to a safe level below the typical 36V abs-max of many automotive-rated ICs. The unidirectional channel means it protects a single polarity rail — positive transients above breakdown are clamped to ground, while negative excursions are forward-biased through the junction. For AC or bidirectional lines, a different series variant would be needed. The supplier device package is the same DO-214AB (SMC), so the land pattern is consistent across Vishay's 1.5SMC series. The tape-and-reel packaging suits automated pick-and-place assembly. Power line protection is not enabled (marked as 'No'), so this device is intended for signal or low-power rail protection rather than main power bus clamping. In automotive telecom or body-control module applications, it guards the 24V nominal supply lines against load-dump and inductive kickback transients. ## Active lifecycle — sourcing posture The production status is listed as Active, so there is no end-of-life or last-time-buy pressure.","metaTitle":"Vishay 1.5SMC24AHM3/I TVS, 1500W, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC24AHM3/I Zener TVS diode, 1500W peak pulse, 20.5V standoff, AEC-Q101 automotive grade.
