For a 48 V nominal system with a 60 V abs-max input rating on the downstream converter, the 92 V clamp provides a 32 V margin — enough to absorb a single-pulse load dump without exceeding the converter's avalanche rating. The DO-201AA axial package is a through-hole form factor with a 0.052-inch lead diameter, suited for point-to-point wiring or PCB mounting with a 0.100-inch lead spacing. The bulk packaging is typical for hand-insertion or low-volume production; the part is not supplied on tape-and-reel.","metaTitle":"1.5KE68AHB0G TVS Diode, 1.5kW, 58.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE68AHB0G automotive Zener TVS, 1500W peak pulse, 58.1V reverse standoff, AEC-Q101 qualified.
