That energy rating puts it squarely in the medium-to-high transient protection bracket — suitable for clamping surges on 48V telecom rails, 28V aircraft buses, or industrial DC supplies where a single bidirectional device handles both polarities. Breakdown voltage starts at 86.5V minimum, with a maximum reverse standoff of 69.2V. The 125.1V clamping voltage at 12A peak pulse current means the protected circuit sees no more than 125V across the transient — a margin that keeps downstream MOSFETs and control ICs inside their avalanche ratings. ## Temp range and package — where it fits physically That makes the 1N6165A a candidate for avionics power entry, engine-bay electronics, and outdoor base-station power supplies where ambient can exceed 175°C and the junction climbs higher under repetitive surge. Through-hole axial package (B, Axial). The leads are solderable into standard through-hole pitch holes — no reflow profile, no MSL concern. For a board that already uses through-hole rectifiers or MOVs, this part drops into the same assembly flow. ## Lifecycle and supply — active, no end-of-life clock Microchip lists the 1N6165A as Active. That means the BOM line is safe for multi-year production runs — no forced redesign window, no hoarding premium.","metaTitle":"1N6165A TVS Diode – Microchip, 1500W, 86.5V Breakdown","metaDescription":"1N6165A from Microchip Technology: Zener TVS, 1500W peak pulse, 86.5V min breakdown, 125.1V clamp, bidirectional, axial through-hole.","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","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"86.5V","Voltage - Clamping (Max) @ Ipp":"125.1V","Voltage - Reverse Standoff (Typ)":"69.2V","Current - Peak Pulse (10/1000µs)":"12A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/127853-1n6138-1n6173a-tvs-diode-series-datasheet","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6165A bidirectional or unidirectional?","answer":"Bidirectional — a single channel that clamps both positive and negative transients.
