The DO-214AB (SMC) package is a standard surface-mount footprint for TVS diodes in this power class, with a low-inductance body that minimizes clamping overshoot. The -55°C to 150°C junction temperature range means it can sit near a hot power supply or in an outdoor enclosure without derating prematurely. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5SMC18 as Obsolete. No official successor order code is recorded, so a pin-compatible drop-in from the same manufacturer is not guaranteed. The part is available through independent surplus and broker channels, sourced to order against a BOM line.","metaTitle":"Littelfuse 1.5SMC18 TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC18 Zener TVS, 1500W peak pulse, 15.3V standoff, DO-214AB.
