The junction operates from -55°C to 175°C, so the device handles the self-heating from a 1500 W pulse at high ambient without derating until the case temperature exceeds 75°C. Above that, follow the power derating curve in the datasheet — typical TVS derate linearly to 0 % at 175°C. ## Package and board-fit — DO-201 axial, through-hole Supplied in a DO-201AA / DO-27 axial leaded package (supplier device package DO-201), this is a through-hole part intended for point-to-point wiring or PCB mounting with 0.042-inch (1.07 mm) diameter leads. The axial body length is typically 7.6 mm; the lead span accommodates standard 0.35-inch (8.9 mm) lead spacing on a prototype board or production PCB. Tape & Box (TB) packaging suits hand-insertion or low-volume automated assembly. No power line protection is claimed — this is a unidirectional device (one channel) for DC rail clamping, not AC mains cross-protection.","metaTitle":"1.5KE170A A0G TVS Diode, 1500W, 145V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE170A A0G Zener TVS, 1500W peak pulse, 145V reverse standoff, 234V clamping at 6.7A.
