The operating junction temperature range spans -55°C to 175°C, covering industrial and automotive under-hood thermal profiles. The single unidirectional channel protects one rail per device.","metaTitle":"1.5KE120-B Littelfuse TVS Diode, 1500W, 102V Standoff","metaDescription":"Littelfuse 1.5KE120-B is an obsolete 1500W unidirectional TVS diode, 102V standoff, 173.25V clamp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5KE","Package":"Bulk","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"DO-201","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"108V","Voltage - Clamping (Max) @ Ipp":"173.25V","Voltage - Reverse Standoff (Typ)":"102V","Current - Peak Pulse (10/1000µs)":"9.2A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f1ea870152ad203d90f672f2af1c1ed0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE120-B/alternatives.json"},"ai":{"faq":[{"question":"What package does the 1.5KE120-B use?","answer":"It comes in a DO-201AA (DO-27) axial-lead through-hole package, supplier device package DO-201.
