The junction temperature range spans -55°C to 175°C. ## Through-hole axial package — board-mount note Supplied in a through-hole axial package (B, Axial). The leads exit the body on both ends, so the part sits flat on the PCB or can be mounted vertically for dense layouts. The copper tab area under the cathode end sets the thermal resistance — a generous pad or a heatsink trace on the board improves surge-handling margin.","metaTitle":"1N6146A TVS Zener Diode — 1.5 kW, 11.4 V Standoff, Active","metaDescription":"Microchip Technology 1N6146A Zener TVS diode, 1500W peak pulse power, 11.4 V reverse standoff, 21 V clamping at 71.4 A.","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":"1500W (1.5kW)","Base Product Number":"1N6146","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Voltage - Breakdown (Min)":"14.25V","Voltage - Clamping (Max) @ Ipp":"21V","Voltage - Reverse Standoff (Typ)":"11.4V","Current - Peak Pulse (10/1000µs)":"71.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.7950","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 1N6146A bidirectional?","answer":"Yes — it is listed as a single bidirectional channel.
