A single bidirectional channel replaces two unidirectional TVS diodes in back-to-back, saving board area and reducing BOM count on signal lines that swing both polarities — RS-485, CAN, or audio lines. ## 53.2V breakdown — selection anchor for 42.6V standoff rail Breakdown voltage is 53.2V minimum, with a reverse standoff of 42.6V. That standoff sits comfortably above a nominal 36V or 48V bus, so the TVS stays off during normal operation. Clamping max is 77V at the rated 6.5A peak pulse current — the clamp voltage is the ceiling the protected IC sees, so confirm the downstream device can survive 77V for the pulse duration. Power line protection is not supported — this part is designed for signal-line or low-power rail protection, not AC mains. ## Active lifecycle — no LTB clock ticking Microchip lists the 1N6124US/TR as Active. The SQ-MELF package is the surface-mount variant of the through-hole 1N6124; the die is identical, so electrical specs match. The -55°C to 175°C junction temperature range covers underhood automotive, industrial oven, and downhole environments where 150°C-rated devices would derate.","metaTitle":"1N6124US/TR Bidirectional TVS Diode – 500W, 53.2V Breakdown","metaDescription":"Microchip 1N6124US/TR bidirectional Zener TVS diode, 500W peak pulse, 53.2V min breakdown, 42.6V standoff, 77V clamp.","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":"SQ-MELF, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, SQ-MELF","Voltage - Breakdown (Min)":"53.2V","Voltage - Clamping (Max) @ Ipp":"77V","Voltage - Reverse Standoff (Typ)":"42.6V","Current - Peak Pulse (10/1000µs)":"6.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.9201","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1N6124US/TR a bidirectional TVS diode?","answer":"Yes.
