The reverse standoff voltage is 13.7 V, with a minimum breakdown of 17.1 V. Housed in a surface-mount SQ-MELF (C) package, the 1N6148AUS is rated for operation from -55°C to 175°C junction temperature, covering military and industrial thermal environments. ## Voltage ratings and clamping margin The 13.7V standoff and 17.1V breakdown give a 3.4V window — tight enough to avoid nuisance triggering on a 12V bus with 5% regulation, but wide enough to accommodate transient overvoltage before the clamping event. Maximum clamping at 25.1 V at 59.8 A peak pulse current defines the voltage the protected circuit must survive. ## Active production and supply posture The SQ-MELF package is a standard surface-mount footprint; the part is. Sourced per RFQ against the BOM quantity — pricing and lead time confirmed at quote time.","metaTitle":"1N6148AUS TVS Diode – 1500W Bidirectional, SQ-MELF","metaDescription":"1N6148AUS bidirectional Zener TVS diode from Microchip Technology. 1500W peak pulse power, 13.7V standoff, 17.1V breakdown, 25.1V clamping.","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, C","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6148","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"C, SQ-MELF","Voltage - Breakdown (Min)":"17.1V","Voltage - Clamping (Max) @ Ipp":"25.1V","Voltage - Reverse Standoff (Typ)":"13.7V","Current - Peak Pulse (10/1000µs)":"59.8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.6000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://www.microsemi.com/document-portal/doc_download/127854-1n6138us-1n6173aus-tvs-diode-series-datasheet","sourceUrl":null},"ai":{"faq":[{"question":"Is the 1N6148AUS a bidirectional TVS diode?","answer":"Yes, it has one bidirectional channel, meaning it clamps both positive and negative transients symmetrically — suitable for AC-coupled or bipolar DC lines where polarity reversal is possible."},{"question":"What package does the 1N6148AUS come in?","answer":"It is supplied in a surface-mount SQ-MELF, C package.
