The 1.5 kW peak pulse rating is referenced to a 10/1000 µs surge shape — the standard automotive ISO 7637 impulse. For shorter, higher-rate transients (1/20 µs or ESD), the effective let-through is lower because the diode's dynamic resistance is smaller at faster rise times; for slower, higher-energy surges the same 1.5 kW rating derates against the longer pulse width. Budget the clamping voltage into your downstream IC's absolute-maximum input rating — 93.6 V should sit cleanly below whatever the protected bus expects. ## AEC-Q101 qualification and automotive temperature margin AEC-Q101 is the discrete semiconductor qualification standard for automotive environments — it covers temperature cycling, humidity bias, UHAST, and surge stress testing. The device is listed as not rated for power-line protection — this is a signal-line or local bus clamp, not a 120/240V mains protector. Use a dedicated mains TVS or MOV for AC-line front-end protection; the 1.5SMCJ58A suits the 12V or 24V supply rail feeding a protected node, sitting close to the connector on the board.","metaTitle":"Panjit 1.5SMCJ58A-AU_R1_000A1 Zener TVS, 58V standoff","metaDescription":"Panjit 1.5SMCJ58A-AU_R1_000A1 unidirectional Zener TVS diode, 58V standoff, 93.6V clamping, 1.5kW peak pulse, AEC-Q101 automotive, DO-214AB (SMC), Active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Series":"Automotive, AEC-Q101","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Automotive","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"64.4V","Voltage - Clamping (Max) @ Ipp":"93.6V","Voltage - Reverse Standoff (Typ)":"58V","Current - Peak Pulse (10/1000µs)":"16A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the 1.5SMCJ58A-AU_R1_000A1 used for in an automotive design?","answer":"This Zener TVS clamps transient spikes on a 12V or 24V automotive supply rail.
