It is qualified to AEC-Q101, meaning it meets the automotive reliability stress and temperature requirements for under-hood and cabin electronics. This makes it a fit for protecting 48 V nominal automotive buses, telecom line cards, or industrial DC supplies from transients like load dump or inductive kickback. ## Voltage ratings and what they mean for the rail The breakdown voltage (VBR) range starts at 53.2 V minimum, which is the point where the device begins to conduct significantly. The clamping voltage (VC) is 77 V maximum at the rated peak pulse current of 19.5 A. This is the voltage the protected circuitry sees during a surge event; a downstream component rated for 80 V or higher has margin. The 1500 W peak pulse power rating means the device can absorb a single 10/1000 µs surge up to that energy level without failing. This simplifies the BOM and saves board space on a 48 V bus that sees surges of either polarity.","metaTitle":"1.5SMC56CAHM3_A/H TVS Diode, 1.5kW, 77V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC56CAHM3_A/H bidirectional TVS diode, 1500W peak pulse power, 77V clamping, AEC-Q101 qualified.
