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.","metaTitle":"Vishay 1.5SMC510AHE3_ALL TVS, 1500W, 434V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC510AHE3_ALL automotive AEC-Q101 TVS diode, 1500W peak pulse, 434V reverse standoff, 698V clamping.
