This clamping margin keeps downstream semiconductors within their safe operating area during load-dump or inductive kickback events. ## AEC-Q101 qualification and temperature range AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the standard. The DO-214AB (SMC) surface-mount package supports standard reflow soldering profiles. The bidirectional configuration uses a single die in a two-terminal package, simplifying PCB layout for a single-rail clamp.","metaTitle":"Vishay 1.5SMC43CAHM3/I TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC43CAHM3/I bidirectional TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101 qualified.
