The DO-214AB (SMCJ) footprint is the standard SMC package; the same land pattern serves the whole 1.5SMC series, so a BOM swap to a different voltage rating within the family requires no board spin.","metaTitle":"1.5SMC39 Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC39 Zener TVS diode, 1500W peak pulse power, 33.3V standoff, DO-214AB.
