The DO-201AA (DO-27) axial-lead package is a through-hole form factor with a 0.052-inch lead diameter — the thermal resistance to ambient depends on the lead length and PCB copper area; a 10 mm lead length on each side into a 25 mm² pad gives roughly 60°C/W junction-to-ambient.","metaTitle":"1.5KE110CH TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE110CH Zener TVS diode, 1500W peak pulse, 89.2V standoff, 158V clamp, AEC-Q101 automotive grade, active production.
