No hot-air rework station needed; a hobbyist or rework tech can replace it on a board in under a minute. The operating junction temperature range spans -55°C to +175°C, which covers everything from outdoor telecom cabinets to under-hood automotive modules. The wide margin means derating for ambient heat is straightforward — at 85°C ambient the 1500W rating is still usable with a linear derating factor. ## Obsolete — sourcing reality for the 1.5KE82C Because the 1.5KE series is a mature, widely cloned TVS family, functionally equivalent parts exist from multiple vendors (same DO-201 package, same 70.1V standoff, same 1500W rating). A cross-reference check against the BOM's voltage and power requirements is the practical next step — the original part number is sourced to order against an RFQ.","metaTitle":"Littelfuse 1.5KE82C TVS Diode, 1500W, DO-201, Bidirectional","metaDescription":"Littelfuse 1.5KE82C bidirectional Zener TVS diode, 1500W peak pulse power, 70.1V standoff, DO-201 axial.
