The 12.8 V standoff means it sits across a 12 V rail without conducting leakage; the 22.26 V clamp is where it holds the surge — downstream circuitry must survive that peak. ## Obsolete — sourcing through surplus channels Littelfuse lists the 1.5SMC15 as Obsolete. This part is available through independent surplus and broker channels — quantities are lot-specific, date-code spread and packaging condition (sealed reel vs cut tape) confirmed at RFQ. No pin-compatible direct replacement is documented; a board spin would be required to use a different TVS family.","metaTitle":"1.5SMC15 Littelfuse Zener TVS, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC15 Zener TVS diode, 1500W peak pulse, 12.8V standoff, DO-214AB.
