The through-hole B, Axial package is a standard form factor for point-to-point wiring or PCB mounting. ## Clamping voltage and surge current Maximum clamping voltage at the peak pulse current of 10.9 A is 45.7 V — this is the voltage the protected circuit sees during a surge event. The reverse standoff voltage (25.1 V typical) tells you the DC operating level below which the diode stays off; above that, it starts to leak and eventually avalanches. Because the part has no power line protection feature, it is intended for signal-line or low-power bus clamping rather than mains-side suppression. The bidirectional construction means a single device replaces two back-to-back unidirectional diodes, saving board area and reducing part count. ## Active production — no obsolescence pressure This removes the sourcing risk of an NRND or obsolete part — you can commit the BOM line without planning a future respin. Availability is confirmed per RFQ; the through-hole package and standard Zener TVS family mean multiple date-code lots are generally accessible through distribution channels.","metaTitle":"1N6118AE3 Zener TVS Diode – 500W, 31.4V Breakdown","metaDescription":"1N6118AE3 from Microchip Technology: Zener transient suppressor, 500W peak pulse power, 31.4V min breakdown, bidirectional, -55°C to 175°C, through-hole B","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","Operating Temperature":"-55°C ~ 175°C (TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, Axial","Voltage - Breakdown (Min)":"31.4V","Voltage - Clamping (Max) @ Ipp":"45.7V","Voltage - Reverse Standoff (Typ)":"25.1V","Current - Peak Pulse (10/1000µs)":"10.9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.8100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72f565c96d1fb1ddee384734173c93c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1N6118AE3 unidirectional or bidirectional?","answer":"It is a single-channel bidirectional suppressor.
