The 27.7 V clamping voltage at 54.2 A peak pulse current keeps the transient below the downstream IC's abs-max rating, assuming the IC is rated for at least 30 V. Operating from -65 °C to 150 °C junction temperature, this part covers the full automotive temperature range — engine bay electronics see 125 °C ambient, leaving 25 °C margin for self-heating during a pulse. ## 1.5 kW peak pulse power in a DO-214AB footprint The DO-214AB (SMC) package is surface-mount, with a large copper tab on the cathode side for the bidirectional structure. Packaged in Tape & Reel (TR), it is compatible with automated pick-and-place assembly. The MSL (moisture sensitivity level) is not listed in the basic spec but for a standard SMC package it is typically MSL 1 — no bake-out required before reflow, though this should be confirmed from the full datasheet for the specific date code.","metaTitle":"1.5SMC20CAHM3_A/H Vishay TVS Diode, 1.5kW, Bidirectional","metaDescription":"Vishay 1.5SMC20CAHM3_A/H bidirectional TVS diode, 1500W peak pulse power, 17.1V standoff, AEC-Q101 qualified.
