Breakdown occurs at a minimum of 285 V, and the clamping voltage is capped at 414 V — this margin protects downstream components rated for 400 V or higher from transients like load dump or inductive kickback on a 256 V nominal bus. ## Through-hole DO-201 package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE300CAHB0G mounts through-hole — typical for high-reliability automotive or industrial boards where vibration resistance and replaceability matter. The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles.","metaTitle":"1.5KE300CAHB0G Taiwan Semiconductor TVS, 1.5 kW, 256 V","metaDescription":"1.5KE300CAHB0G bidirectional Zener TVS, 1500 W peak pulse, 256 V standoff, AEC-Q101.
