Single unidirectional channel — the cathode band marks the anode; reverse polarity protection requires a second device or a bridge arrangement. ## DO-201 axial — board-fit and replacement considerations The DO-201AA (DO-27) axial leaded package suits point-to-point wiring, terminal blocks, or through-hole PCB layouts where the lead bend radius and hole diameter (typically 1.0–1.3 mm) must match the assembly process. No power line protection rating — this device is intended for signal and low-power rail transient clamping, not primary AC mains suppression.","metaTitle":"YAGEO 1.5KE170A/B Zener TVS, 1500W, DO-201","metaDescription":"YAGEO 1.5KE170A/B Zener TVS diode, 1500W peak pulse, 145V standoff, 234V clamp, DO-201 axial.
