The single bidirectional channel means one device protects both positive and negative overvoltage events on a line, saving board space compared to two unidirectional diodes back-to-back. Minimum breakdown voltage is 104.5V, so the diode begins conducting at that threshold. The clamping voltage at peak pulse current is 151.3V — the maximum voltage the protected circuit sees during a surge. For a 86.6V nominal rail, this leaves a 17.9V margin above the standoff before clamping, which is typical for a Zener-based TVS. The wide range means the breakdown voltage shifts less than 10% across temperature, but derate the peak pulse power above 25°C per the datasheet curve. ## Active production – sourcing through distribution The through-hole B Axial package is a leaded form factor compatible with wave soldering and hand rework. No moisture sensitivity level (MSL) concern — axial diodes are not moisture-sensitive.","metaTitle":"1N6131A TVS Diode – 500W Bidirectional Zener","metaDescription":"1N6131A from Microchip Technology: 500W peak pulse power, bidirectional Zener TVS, 104.5V min breakdown, 151.3V clamping, -55°C to 175°C, through-hole axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Microchip Technology","Type":"Zener","Series":"-","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"B, Axial","Product Status":"Active","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":"Axial","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":"$13.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72f565c96d1fb1ddee384734173c93c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1N6131A a bidirectional or unidirectional TVS diode?","answer":"It is a single-channel bidirectional Zener TVS.
