1.5kW Zener TVS in a DO-201 axial package
The 1.5KE82A-B: Housed in a DO-201AA / DO-27 axial-lead package, it mounts through-hole on a PCB or terminal strip.
Obsolete — sourced through independent channels
Diodes Incorporated lists the 1.5KE82A-B as obsolete. No official successor order code is recorded on the lifecycle entry.
Clamping voltage and peak current — the real protection envelope
When a transient exceeds the 77.9 V minimum breakdown threshold, the device avalanches and clamps to 113 V maximum at the rated 13.3 A peak pulse current. That 113 V ceiling is what the downstream silicon must survive — if the protected rail is a 48 V telecom bus, the clamp margin is roughly 2.4× the nominal, which most downstream DC-DC converters with 100 V abs-max input can ride through.
