1500W peak pulse, 434V standoff — the protection window for a 400V bus
The 1.5SMC510AHE3_ALL: This clamping window — 434V working standoff, 485V minimum breakdown, 698V clamp — is sized for protecting 400V nominal DC buses in automotive and industrial power systems, where transients from load dump or inductive kickback must be shunted before they reach downstream silicon.
AEC-Q101 qualification and active lifecycle
The 1.5SMC510AHE3_ALL carries AEC-Q101 automotive qualification, meaning it has passed the stress tests (temperature cycling, high-temperature reverse bias, ESD) required for under-hood and chassis-mounted electronics. Production status is Active per the manufacturer's lifecycle record — no end-of-life notice or last-time-buy window is on file.
DO-214AB SMC package — board-fit and storage
The package is moisture-sensitive — store the reels dry per the floor-life label on the reel. The single unidirectional channel means the cathode band on the package must align with the protected rail; reverse insertion bypasses the protection entirely.
