The SQ-MELF (C) surface-mount package suits automated assembly and high-reliability applications where a hermetic seal is not required but a robust ceramic body is preferred. ## Temperature range and environment fit Rated for continuous junction temperature from -55°C to 175°C, this part is specified for avionics, downhole instrumentation, and outdoor telecom where the ambient temperature can swing beyond the commercial range. The 175°C upper limit gives headroom for derating when the device is mounted near hot components or in a sealed enclosure with limited airflow. ## Lifecycle and sourcing posture The base product number is 1N6144, and the 'AUS' suffix denotes the SQ-MELF package variant. Verify the BOM line calls for this exact suffix.","metaTitle":"1N6144AUS Zener TVS Diode – 1500W, Bidirectional, SQ-MELF","metaDescription":"1N6144AUS from Microchip Technology – Zener TVS diode, 1500W peak pulse, bidirectional, 9.1V standoff, 16.9V clamp, -55°C to 175°C, SQ-MELF 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":"Surface Mount","Package / Case":"SQ-MELF, C","Product Status":"Active","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1N6144","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)":"11.4V","Voltage - Clamping (Max) @ Ipp":"16.9V","Voltage - Reverse Standoff (Typ)":"9.1V","Current - Peak Pulse (10/1000µs)":"88.8A"}},"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 1N6144AUS bidirectional?","answer":"Yes, it is a single bidirectional channel.
