Reverse standoff of 43 V sets the working voltage at which the device presents high impedance — it sits across the line and does nothing until a transient arrives. The 1500 W peak pulse rating defines the surge energy budget the device can absorb without degradation — the 69.4 V clamping voltage at 21.6 A is the operating point at that rated surge level. For shorter-duration transients the clamping voltage stays lower; a slower or higher-energy surge pushes the clamping closer to that ceiling. The 150°C TJ ceiling gives thermal headroom to absorb a surge without the junction temperature self-running away. AEC-Q101 qualification means the part has passed the automotive stress tests for discrete semiconductors — temperature cycling, humidity bias, and surge life are screened to the level required by original equipment manufacturers.","metaTitle":"1.5SMCJ43CA-AU_R1_000A1 TVS Diode, 43V Standoff, SMC Package","metaDescription":"Panjit 1.5SMCJ43CA-AU_R1_000A1, automotive bidirectional TVS diode, 43V standoff, 69.4V clamping, 1500W peak pulse, AEC-Q101, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Panjit International Inc.","Type":"Zener","Grade":"Automotive","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C ~ 150°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC (DO-214AB)","Voltage - Breakdown (Min)":"47.8V","Voltage - Clamping (Max) @ Ipp":"69.4V","Voltage - Reverse Standoff (Typ)":"43V","Current - Peak Pulse (10/1000µs)":"21.6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ43CA-AU_R1_000A1/alternatives.json"},"ai":{"faq":[{"question":"What is 1.5SMCJ43CA-AU_R1_000A1 used for?","answer":"It is a bidirectional TVS diode protecting a 43 V rail from voltage transients — automotive ECU inputs, sensor lines, and power rails that need clamp-down protection without latching.
