The axial leads allow point-to-point wiring or PCB mounting with the body standing off the board. The package is unidirectional — one channel per device, with the cathode band indicating the polarity for DC rail protection. It is not rated for power line protection (AC mains continuous overvoltage), so it is suited for DC bus, signal line, or low-voltage AC secondary-side clamping.","metaTitle":"YAGEO 1.5KE47A/B TVS Diode, 1500W, 40.2V Standoff","metaDescription":"YAGEO 1.5KE47A/B Zener TVS diode, 1500W peak pulse power, 40.2V reverse standoff, DO-201 package.
