No official successor is listed, so any replacement will require a board spin or a parametric cross to a different TVS diode in the same DO-214AB footprint. Housed in a DO-214AB (SMC) package, the 1.5SMC150 is a surface-mount device with a single unidirectional channel. The SMC footprint is larger than the SMA/SMB siblings, which helps with thermal dissipation during the pulse — the 1500 W rating assumes the standard copper land pattern on the PCB.","metaTitle":"Littelfuse 1.5SMC150 TVS Diode, 1500W, DO-214AB","metaDescription":"Obsolete Littelfuse 1.5SMC150 Zener TVS, 128V standoff, 217.35V clamp, 1500W peak pulse.
