It sits in parallel with a signal or secondary-side rail and clamps any voltage spike that exceeds its breakdown threshold, protecting downstream ICs and passive components from surge damage. This part is listed as general-purpose and carries Power Line Protection = No, so it is not intended for AC line-front protection — its domain is board-level clamping on 12 V nominal rails. ## Standoff, breakdown, and clamping — what each voltage means The 13 V reverse standoff is the maximum voltage the TVS can block indefinitely in the reverse direction during normal circuit operation — the rail can sit 13 V below ground without the diode conducting. The 14.4 V minimum breakdown is the point where it begins to turn on; until that threshold is crossed the downstream circuit sees nothing.","metaTitle":"1.5SMCJ13C TVS Diode, 1500W Peak, 13V Standoff, DO-214AB","metaDescription":"Diotec 1.5SMCJ13C unidirectional TVS diode, 1500 W peak pulse, 63 A peak pulse current, 13 V standoff, 23.8 V clamping, DO-214AB SMC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Diotec Semiconductor","Type":"Zener","Series":"-","Package":"Strip","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-50°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC/DO-214AB","Voltage - Breakdown (Min)":"14.4V","Voltage - Clamping (Max) @ Ipp":"23.8V","Voltage - Reverse Standoff (Typ)":"13V","Current - Peak Pulse (10/1000µs)":"63A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8068","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3fb0502b23c3703cafef426b7b2bf7e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMCJ13C/alternatives.json"},"ai":{"faq":[{"question":"What is the 1.5SMCJ13C's listed type and package?","answer":"It is listed as a Zener type in a Strip package, surface-mounted in the SMC/DO-214AB case."},{"question":"Is the 1.5SMCJ13C unidirectional or bidirectional?","answer":"It is a unidirectional TVS with 1 bidirectional channel — meaning a single-polarity clamp.
