Automotive-grade transient suppression for 48V rails
The 1.5KE68AHB0G: Its 58.1 V reverse standoff voltage and 64.6 V minimum breakdown threshold place it on a 48 V nominal bus — the clamping onset sits above the steady-state rail and below the 92 V maximum clamp, so a load-dump or inductive kick is shunted before downstream semiconductors see damaging voltage.
Clamping voltage and pulse current at the BOM line
At the 17 A peak pulse current (10/1000 µs waveform), the clamping voltage is held to 92 V maximum. 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.
