If you are swapping one in the field, the SMC body is large enough to hand-solder with a standard iron — no hot-air station needed. Listed as Active — no end-of-life notice, no last-time-buy window. For telecom and automotive BOMs that require a documented PPAP, this part carries the automotive pedigree.","metaTitle":"Vishay 1.5SMC220CAHM3/I TVS Diode, 185V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC220CAHM3/I bidirectional TVS diode, 1500W peak pulse, 185V standoff, AEC-Q101, DO-214AB.
