The 1.5KE82AHB0G: Breakdown voltage is specified at 77.9 V minimum, with a reverse standoff of 70.1 V — the diode remains high-impedance below this level, drawing negligible leakage in normal operation. The DO-201AA axial-lead package (also known as DO-27) mounts through-hole, suited for point-of-entry protection on power inputs where creepage distance and solder-joint reliability matter.
It is AEC-Q101 qualified, the automotive stress-test qualification for discrete semiconductors. This covers temperature cycling, high-temperature reverse bias, and other reliability screens required for under-hood and passenger-compartment electronics.
