It delivers 1500W (1.5kW) peak pulse power per the 10/1000µs waveform, with a reverse standoff voltage of 8.55V and a maximum clamping voltage of 18.6V at the rated peak pulse current. The single bidirectional channel means it protects both polarities in one package, simplifying layout for AC or bipolar DC lines. ## Rework and mounting — DO-214AB SMC Housed in a DO-214AB SMC surface-mount package, this part is straightforward to rework with hot air. The body is large enough to get a good grip with tweezers, and the cathode band (or lack thereof for bidirectional) is clearly marked. Standard SMC footprint, no exposed pad — just align and reflow. No special bake requirements beyond standard MSL handling. ## Temperature range and environment The 150°C limit gives headroom for self-heating during repetitive surge events, but derate the peak pulse power above 25°C per the datasheet curve.","metaTitle":"STMicroelectronics SM15T10CA TVS Diode, 1500W Bidirectional","metaDescription":"SM15T10CA bidirectional TVS diode from STMicroelectronics TRANSIL series. 1500W peak pulse power, 8.55V standoff, DO-214AB SMC package. -55°C to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"SM15T, 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":"SM15T10","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"SMC","Voltage - Breakdown (Min)":"9.5V","Voltage - Clamping (Max) @ Ipp":"18.6V","Voltage - Reverse Standoff (Typ)":"8.55V","Current - Peak Pulse (10/1000µs)":"538A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/539ce92ad6505c8a9d704773ec1ef151.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SM15T10CA bidirectional or unidirectional?","answer":"It is a single-channel bidirectional device, meaning it clamps both positive and negative transients symmetrically.
