Product details

1500 W peak pulse, 70.1 V standoff — the clamping profile

The 1.5KE82C-B: Its 70.1 V reverse standoff voltage means the part stays transparent on a nominal 48 V or 60 V rail, only clamping when a transient pushes past that threshold. That 118.65 V clamp is the hard limit the downstream circuitry must survive — a 100 V-rated MOSFET on the same rail is at risk if the TVS lets the voltage rise that high before the avalanche kicks in.

DO-201 axial — field-swappable with a soldering iron

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE82C-B is a through-hole part. The body is marked with the polarity band for the bidirectional version — no orientation guesswork on the board. A standard soldering iron and a pair of cutters are all you need to swap it in the field; no hot-air station required. The axial leads fit into plated through-holes on a 0.6 mm to 1.2 mm PCB. Lead spacing is typically 0.400 inches (10.16 mm) for this package family — check the board layout before committing the replacement.

Obsolete — sourcing through independent channels

Littelfuse lists the 1.5KE82C-B as obsolete. For a BOM that already uses this order code, the sourcing posture is quoted-to-order against the line quantity.
