What the 1.5KE82C protects and how it clamps
It clamps transients at 118.65V maximum while conducting 13.5A peak pulse current — enough to shunt a 24V or 48V DC bus spike or an AC line transient on a control transformer secondary.
Package, temperature range, and hand-solderability
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE82C is a through-hole part — the leads are thick enough for a standard soldering iron and the body is easy to grip with a heatsink clip. 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.
