Breakdown starts at 83.3 V minimum, and the device clamps the transient at 121 V maximum at peak pulse current. This 46 V window between standoff and clamp defines the margin the downstream circuitry must survive. A single bidirectional channel protects both polarities on the same line, which simplifies board layout compared to pairing two unidirectional devices back-to-back. ## DO-214AB package and tape-and-reel delivery ## Active lifecycle, single-source reality This is a single-source part from Microchip; no direct second source is published. For BOM risk management, qualifying an alternate from the same DO-214AB TVS family before allocation tightens is a prudent step.","metaTitle":"SMCJ75CAE3/TR13 TVS Diode – 1500W, 75V, Bidirectional","metaDescription":"SMCJ75CAE3/TR13 Zener TVS diode from Microchip Technology. 1500W peak pulse power, 75V reverse standoff, bidirectional, DO-214AB (SMC) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Tape & Reel (TR)","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":"SMCJ75","Operating Temperature":"-65°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"83.3V","Voltage - Clamping (Max) @ Ipp":"121V","Voltage - Reverse Standoff (Typ)":"75V","Current - Peak Pulse (10/1000µs)":"12.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5850","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SMCJ75CAE3/TR13 and SMCJ75A?","answer":"The SMCJ75CAE3/TR13 is a bidirectional device (one channel protects both polarities), while the SMCJ75A is a unidirectional device.
