1.5 kW clamping for 185 V rails
The 1.5KE220CA A0G: With a peak pulse power rating of 1500 W (10/1000 µs waveform), it handles 4.8 A peak pulse current before the clamping voltage rises to 328 V maximum. Breakdown occurs between 209 V (minimum) and the clamping ceiling — that 119 V headroom from the 185 V standoff gives the diode room to absorb energy without conducting during normal line ripple.
DO-201 axial — through-hole survivability
Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE220CA A0G mounts through-hole — the body and leads handle the thermal pulse of a 1.5 kW surge without the trace-lift risk a surface-mount part faces on a thin board.
Active — no end-of-life pressure
General-purpose application rating means it is not locked to a single end market — power supplies, motor drives, battery chargers, and telecom rectifiers all use this class of 1.5 kW axial TVS.
