Quantities are lot-specific and confirmed at RFQ; no factory lead time applies. ## 1500 W peak pulse — what the rating means Rated for 1500 W peak pulse power dissipation under the 10/1000 µs waveform. This is the energy-handling ceiling for a single transient event — the device absorbs the surge and clamps the voltage, then resets. ## AEC-Q101 and the automotive pedigree Part of the Automotive, AEC-Q101 qualified 1.5SMC series using Vishay's TransZorb® silicon-avalanche technology. Unidirectional — one channel protects a single rail. ## DO-214AB (SMC) — board-fit note Supplied in DO-214AB (SMCJ) surface-mount package, Tape & Reel. The 548 V clamping voltage means the PCB clearance and creepage around the cathode tab should follow the peak transient voltage, not the standoff — a 600 V-rated clearance rule is a safe starting point.","metaTitle":"1.5SMC400AHE3_A/I TVS Diode, 1500W, 342V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC400AHE3_A/I 1500W TVS, 342V reverse standoff, 548V clamping, AEC-Q101.
