The 1.5KE220CA R0G is a bidirectional Zener-type TVS diode from Taiwan Semiconductor's 1.5KE series, designed to clamp transients on general-purpose power and signal lines. The reverse standoff voltage is 185V — the diode remains transparent below this level, drawing negligible leakage. This clamping margin protects 200V-class bus rails and intermediate DC links from overvoltage events.
It is supplied in a DO-201AA (DO-27) axial-lead through-hole package, shipped on tape and reel.
