Its reverse standoff voltage is 12V, meaning the diode does not conduct at normal line voltage; when a surge exceeds the 13.6V minimum breakdown, it clamps at 22.6V maximum and shunts up to 125A of 8/20µs peak pulse current. The 500W peak pulse power rating defines the energy it can absorb in a single surge event — a key number for derating against the expected transient energy on an industrial control or telecom line. The B, Axial package is a through-hole form factor — the lead spacing and body diameter match standard 0.100-inch pitch board layouts. ## Sourcing and compliance – authorized channel, RoHS As an Active Microchip part, the 1N6463 is available through authorized distribution. The part is RoHS compliant per standard Microchip declarations. For volume BOM positions, the exact ordering code 1N6463 is the through-hole Axial variant — no suffix for tape or reel, since the package is Bulk. Quoted to order against your line-item quantity.","metaTitle":"1N6463 Zener TVS Diode – 500W, 12V Standoff, Axial","metaDescription":"1N6463 from Microchip Technology: Zener TVS diode, 500W peak pulse power, 12V reverse standoff, 22.6V clamping, Axial package.","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":"1N6463","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"Axial","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"13.6V","Voltage - Clamping (Max) @ Ipp":"22.6V","Voltage - Reverse Standoff (Typ)":"12V","Current - Peak Pulse (10/1000µs)":"125A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e98ac610a1de8a2054ffc6757c2a948b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the power rating of 1N6463?","answer":"The peak pulse power rating is 500W, tested with an 8/20µs waveform.
