This is a general-purpose transient suppressor for unidirectional rail protection — the single diode handles one polarity; a second device in anti-series covers bidirectional lines. ## DO-201 axial footprint and thermal reach Housed in a DO-201AA (DO-27) axial-lead package with a DO-201 supplier device case code, the part is a through-hole mount. The 1500 W rating assumes the leads are soldered into a PCB with adequate copper area to sink the pulse heat — the junction temperature range spans -55°C to 175°C, so the device handles repetitive transients as long as the average power stays within the thermal derating curve for the ambient condition. The axial body is 9.1 mm long typical for the DO-201AA format, with 1.3 mm diameter leads. Lead spacing on the PCB should match the standard 0.4-inch (10.16 mm) hole pitch used for this package family.","metaTitle":"1.5KE220A A0G TVS Diode, 1500W, 185V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE220A A0G Zener TVS, 1500W peak pulse, 185V reverse standoff, 328V clamping.
