The 47.8 V reverse standoff voltage means this TVS starts conducting significantly above the normal 48 V bus level, so a 48 V telecom or automotive supply rail stays below the leakage threshold during normal operation. Clamping at 77 V limits the transient to a level that downstream 80 V-rated MOSFETs or controllers can survive. ## Automotive qualification and temperature range AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and humidity bias. The Automotive grade also flags that the part is on a PPAP-ready baseline, so a Tier-1 supplier can request the production part approval process documentation for their customer submission. ## Package and board-fit — DO-214AB (SMC) The cathode band on the bidirectional version is absent — both pins are identical, so orientation during pick-and-place is non-critical. The SMC body is larger than the SMA/SMB siblings, which helps spread the heat from the 1500 W pulse into the board copper. Supplied in Tape & Reel, compatible with standard 12 mm embossed carrier tape per EIA-481. The reel quantity is typically 850 or 3000 depending on the reel diameter — confirm the count at RFQ for your BOM line. ## Sourcing and lifecycle — active production Cross-reference at RFQ if dual-sourcing is required.","metaTitle":"1.5SMC56CAHM3_A/I Vishay TVS, 1500W, 77V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC56CAHM3_A/I TVS diode, 1500W peak pulse, 77V clamping, AEC-Q101 automotive grade.
