For a nominal 86.6 V DC rail, the TVS stays off during normal operation and only conducts when the transient pushes the line above the breakdown threshold. The 151.3 V clamping ceiling limits the voltage the downstream circuitry sees during the pulse — a critical number for selecting the voltage rating of the protected components. ## SQ-MELF package and temperature range Housed in the SQ-MELF B package, a surface-mount ceramic body with solderable end caps. The junction temperature range spans -55°C to 175°C, suiting it for avionics, downhole, and other high-temperature environments where plastic-packaged TVS diodes would degrade. The B, SQ-MELF package is the same footprint as the standard MELF but with a square body for better pick-and-place alignment. No power line protection feature — this is a unidirectional/bidirectional transient suppressor, not a rail clamp IC.","metaTitle":"1N6131US Zener TVS Diode – 500 W, 86.6 V Standoff, SQ-MELF","metaDescription":"1N6131US from Microchip Technology: Zener transient voltage suppressor, 500 W peak pulse power, 86.6 V reverse standoff, bidirectional, SQ-MELF B package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Packaging":"Bulk","Part Status":"Active","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"SQ-MELF, B","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6131","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)":"104.5V","Voltage - Clamping (Max) @ Ipp":"151.3V","Voltage - Reverse Standoff (Typ)":"86.6V","Current - Peak Pulse (10/1000µs)":"3.3A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.7400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6131US bidirectional?","answer":"Yes, it has one bidirectional channel, meaning it clamps transients of both polarities — useful for AC-coupled lines or bipolar supplies where a single device replaces two unidirectional TVS diodes back-to-back."},{"question":"What is the peak pulse power rating of the 1N6131US?","answer":"500 W peak pulse power measured with a 10/1000 µs exponential waveform.
