The minimum breakdown voltage is 38.75V, so the part begins conducting before the rail exceeds that threshold. This bidirectional configuration protects circuits where the signal or power rail swings both positive and negative relative to ground. Littelfuse lists the 1.5SMC43C as Obsolete. Date-code provenance and lot traceability are verified before shipment.","metaTitle":"Littelfuse 1.5SMC43C TVS Diode, 1.5kW Bidirectional","metaDescription":"Littelfuse 1.5SMC43C Zener TVS, 1500W peak pulse, bidirectional, DO-214AB.
