At the clamping voltage of 113V, the peak pulse current is 13.3A — meaning the diode must survive that current impulse while keeping the clamped voltage below 113V at the board rail. The CA suffix marks a bidirectional part: it clamps both positive and negative transients, so it suits single-polarity rails where the protected node swings both directions during fault events. ## Temperature grade and automotive qualification AEC-Q101 qualification means it passed the automotive stress suite: humidity, temperature cycling, and surge life — the test sequence that separates a consumer-grade TVS from one that survives a vehicle lifetime. ## Package and footprint for this power class The DO-214AB (SMC) package is the standard medium-power TVS footprint — the cathode bar in the center of the package identifies the polarity end, and the wide pad underneath carries the thermal path from the junction to the board copper. Supplied on tape and reel — the standard automotive reel count of 3000 per reel suits high-volume assembly; confirm the reel orientation matches your pick-and-place tooling before committing to the BOM. ## Sourcing posture Active product status — the part is ordered to BOM quantity through independent distribution, with availability and lead time confirmed at RFQ.","metaTitle":"1.5SMC82CAHE3/9AT TVS Diode, 113V Clamping, DO-214AB","metaDescription":"Vishay bidirectional TVS diode, 1.5 kW peak pulse, AEC-Q101 automotive qualified.
