The bidirectional configuration makes it suitable for AC lines or bipolar supply protection where polarity is not fixed. The minimum breakdown voltage is 16.7 V, which gives a 1.7 V margin above the 15 V standoff — enough to avoid nuisance triggering from normal rail ripple or load transients. For a 15 V rail with downstream components rated at, say, 30 V absolute maximum, this clamp level leaves a guard band; for a 12 V rail you would step down to the SMCJ12A or SMCJ12CA. ## Peak pulse current and waveform context The 308 A peak pulse current is specified with the 8/20 µs waveform, a common industrial surge shape. The 1500 W rating uses the longer 10/1000 µs waveform — the part's energy-handling capability is waveform-dependent, so when comparing against other TVS diodes make sure the test conditions match. Power line protection is marked as 'No', meaning this device is intended for signal or low-voltage DC bus protection, not for direct AC mains clamping.","metaTitle":"STMicroelectronics SMCJ15CA-TR TVS Diode","metaDescription":"STMicroelectronics SMCJ15CA-TR TRANSIL™ TVS diode, 1500W peak pulse power, 15V standoff, bidirectional, DO-214AB SMC package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SMCJ, TRANSIL™","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"SMCJ15","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Voltage - Breakdown (Min)":"16.7V","Voltage - Clamping (Max) @ Ipp":"32.5V","Voltage - Reverse Standoff (Typ)":"15V","Current - Peak Pulse (10/1000µs)":"308A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/afa32e66ad58d9d3b67a92acb79ea14b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SMCJ15CA-TR/alternatives.json"},"ai":{"faq":[{"question":"Does SMCJ15CA-TR fit into a DO-214AB footprint?","answer":"Yes.
