1500W peak pulse power in an axial DO-201 package
The 1.5KE24AH: That 47A peak pulse current at the 33.2V clamping voltage means it shunts transient energy away from downstream circuitry during an overvoltage event, holding the line at the clamp until the surge dissipates. The 20.5V reverse standoff voltage is the DC operating level — the diode stays off below this, drawing negligible leakage. Breakdown starts at 22.8V minimum, so a 24V nominal rail with 10% tolerance sits safely under the standoff, and the diode only conducts when the transient pushes above the breakdown threshold.
Automotive grade with AEC-Q101 qualification
The DO-201AA axial package with through-hole mounting suits high-reliability power stages and battery-connected circuits where a surface-mount part might be thermally or mechanically marginal. The DO-201 supplier device package is the standard footprint for this power class.
