The 10.2 V reverse standoff voltage means the diode stays transparent on a 10 V rail; it starts conducting at 10.8 V minimum breakdown. Littelfuse has marked the 1.5SMC12 as Obsolete. No pin-compatible direct replacement from Littelfuse is documented. Housed in a DO-214AB (SMC) surface-mount package, also referred to as SMCJ.","metaTitle":"Littelfuse 1.5SMC12 TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC12 Zener TVS diode, 1500W peak pulse power, 10.2V standoff, DO-214AB.
