No power line protection is offered — this is a unidirectional Zener TVS for signal or DC rail clamping, not for AC mains surge suppression. ## Sourcing and lifecycle posture No official successor or pin-compatible alternative is documented; the 1.5KE series covers a range of standoff voltages, so a different voltage variant would require a BOM change.","metaTitle":"YAGEO 1.5KE220A/B Zener TVS, 1500W, 185V Standoff, DO-201","metaDescription":"YAGEO 1.5KE220A/B Zener TVS diode, 1500W peak pulse power, 185V reverse standoff, 328V clamping at 4.6A.
