The single unidirectional channel handles one polarity; for AC lines you would need two devices back-to-back. ## Automotive qualification and temperature grade The TransZorb® construction delivers the 1500 W pulse rating with a fast response time typical of Zener avalanche diodes. Vishay lists this part as Obsolete. For new designs or BOM positions that need an active AEC-Q101 TVS in the same voltage class, a parametric search on 434 V standoff and DO-214AB package will yield current-generation alternatives from Vishay or competitors — expect a board-spin if the footprint or electrical characteristics shift. ## Sourcing reality for an obsolete automotive TVS No pin-compatible direct replacement from Vishay is documented. If your board is already in production with the 1.5SMC510AHE3_A/H, the safest path is to secure a last-time buy of the remaining surplus inventory. For a new layout, a current-production TVS with the same DO-214AB footprint and 434 V standoff avoids a respin.","metaTitle":"Vishay 1.5SMC510AHE3_A/H TVS, 1500W, 434V Standoff, DO-214AB","metaDescription":"Obsolete Vishay 1.5SMC510AHE3_A/H Zener TVS diode, 1500W peak pulse, 434V reverse standoff, AEC-Q101 qualified.
