The 43.68V clamp at 11.4A peak pulse current gives a 20V margin above the 22.8V standoff — enough headroom for a 24V bus with 10% tolerance without nuisance triggering. ## Active production, hermetic package Microchip lists the 1N6117US as Active. The SQ-MELF, B package is a hermetic surface-mount ceramic body suited for high-reliability and extended temperature environments.","metaTitle":"1N6117US Zener TVS Diode – 500W, 22.8V Standoff, SQ-MELF","metaDescription":"1N6117US from Microchip Technology: Zener TVS, 500W peak pulse power, 22.8V reverse standoff, bidirectional, SQ-MELF surface mount.","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":"Surface Mount","Package / Case":"SQ-MELF, B","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"500W","Base Product Number":"1N6117","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"B, SQ-MELF","Voltage - Breakdown (Min)":"27.08V","Voltage - Clamping (Max) @ Ipp":"43.68V","Voltage - Reverse Standoff (Typ)":"22.8V","Current - Peak Pulse (10/1000µs)":"11.4A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.2400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5dbd5050221203b922ebce5a7a6e86e6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the peak pulse power rating of the 1N6117US?","answer":"The 1N6117US is rated for 500W peak pulse power under a 10/1000µs waveform.
