The single unidirectional channel means it protects one polarity — the cathode band orients toward the positive rail being clamped. ## Package and board-fit decision The tape-and-reel packaging suits automated pick-and-place assembly. ## Sourcing an obsolete AEC-Q101 TVS Vishay has marked the 1.5SMC350AHE3_A/H as obsolete. For new designs, a 300V standoff, 1500W peak-pulse, AEC-Q101 qualified TVS in a DO-214AB package from the same or an alternate manufacturer should be evaluated for functional equivalence — a board layout change is not required if the footprint and pinout match, but the breakdown and clamp voltage tolerances must be verified against the rail being protected.","metaTitle":"1.5SMC350AHE3_A/H Vishay TVS, 1500W, 300V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC350AHE3_A/H Zener TVS diode, 1500W peak pulse, 300V standoff, DO-214AB SMC.
