The bidirectional configuration means a single part handles positive and negative transients — useful on AC-coupled signal lines or bipolar power buses. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE47CA/B is a through-hole component suited for point-to-point wiring or PCB mounting with 0.100-inch pitch holes. The DO-201 footprint is standard across the 1.5KE family, so a single board layout accepts the full voltage range from 6.8V to 440V. The device does not include power line protection features — it is a pure transient suppressor for signal or low-power DC rails. YAGEO lists the 1.5KE47CA/B as Active in production.","metaTitle":"YAGEO 1.5KE47CA/B TVS Diode, 1500W, DO-201, Bidirectional","metaDescription":"YAGEO 1.5KE47CA/B Zener TVS diode, 1500W peak pulse, 40.2V standoff, bidirectional, DO-201 axial.
