1500W peak pulse in an axial DO-201
The 1.5KE82A R0G: That 1500 W rating means it can absorb a single pulse of that energy without failing — the key spec for a line-side or DC-rail clamp where a transient hits once and the part must survive it. The 70.1 V standoff is the DC bus or signal line voltage the diode does not conduct under — pick this so it sits above the normal rail and below the downstream device's abs-max rating. Housed in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), through-hole mounted. The 1.5KE series is a standard JEDEC outline — the lead spacing and body diameter match existing PCB layouts for the 1.5 kW TVS footprint.
Temperature range and deployment context
The wide Tj range means the clamping voltage and leakage current are stable across the temperature extremes found in outdoor telecom cabinets, engine bays, or industrial control enclosures. The part is marked as General Purpose in application — no power line protection (no internal filter), so it is intended for signal or low-voltage DC rail transient suppression, not AC mains primary protection.
Lifecycle and procurement
The axial leads are taped per EIA-296 for automatic insertion — a standard reel format for through-hole TVS diodes.
