TVS diode for 64 V rails under the hood
The 1.5KE75AHB0G is a 1500 W peak-pulse Zener TVS diode from Taiwan Semiconductor's 1.5KE series, specified with a 64.1 V reverse standoff and a 103 V clamping point at 15 A (10/1000 µs waveform).
Clamping voltage and breakdown margin
The minimum breakdown voltage is 71.3 V, so a 64.1 V nominal rail (e.g., a 48 V battery after DC-DC conversion or a 60 V bus) stays below the avalanche threshold during normal operation while the TVS clamps transients before they reach 103 V. The unidirectional Zener construction (single channel) means it protects only against positive overvoltage relative to ground; negative spikes require a separate bidirectional or series-opposed pair.
Through-hole axial package for high-surge layouts
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE75AHB0G is a through-hole part that mounts by bending the leads through plated holes — the large body and thick leads carry the 1500 W pulse without trace lift-off, unlike surface-mount TVS diodes that need wide copper pads. Supplied in bulk tube packaging, it suits hand-assembly or wave-solder runs; no reel or tape-and-reel handling is required for low-volume or prototype builds.
