With no power line protection rating, this unidirectional TVS is intended for DC signal or low-voltage supply rails, not AC mains transient suppression — the 10/1000 µs pulse shape matches IEC 61000-4-5 surge testing for equipment-level transients. ## DO-201 axial package — through-hole footprint and temperature range Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE47A A0G mounts through-hole — a common footprint for replacement in existing power supply and I/O protection designs where surface-mount TVS arrays are not an option.","metaTitle":"1.5KE47A A0G TVS Diode, 1500W, 40.2V Standoff, DO-201","metaDescription":"1.5KE47A A0G Taiwan Semiconductor Zener TVS, 1500W peak pulse, 40.2V reverse standoff, 64.8V clamp.
