If the downstream device's absolute maximum rating is below this, a lower-clamping TVS or additional filtering is needed. No power derating is required until ambient exceeds 25°C, but above that the peak pulse power must be reduced per the datasheet derating curve. Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE15A R0G is a through-hole part suited for point-to-point wiring or PCB mounting with 0.042-inch diameter lead holes on a 0.375-inch lead spacing. The axial body allows vertical or horizontal mounting depending on board layout constraints. The 1.5KE series includes multiple voltage variants, but the 1.5KE15A is the specific 15V unidirectional version in this package.","metaTitle":"1.5KE15A R0G TVS Diode, 1500W, 12.8V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE15A R0G Zener TVS diode, 1500W peak pulse power, 12.8V reverse standoff, 74A Ipp, DO-201 axial.
