This combination protects downstream components from overvoltage until the surge energy dissipates. The junction temperature range spans -55°C to 175°C, covering the full automotive thermal profile without derating the peak pulse power at the high end. Supplied in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE300AH is soldered into the board via wave or hand-soldering. No moisture sensitivity level applies — axial diodes do not require bake-out before assembly. The package body is cylindrical, 9.5 mm length typical, with leads 1.3 mm diameter for the cathode band.","metaTitle":"TSC 1.5KE300AH Zener TVS, 1500W, 256V Standoff, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE300AH Zener TVS diode, 1500W peak pulse, 256V standoff, 414V clamping, AEC-Q101 automotive grade.
