With a 64.1 V reverse standoff, the diode idles off in normal operation and begins conducting once the transient pushes the line above the 71.3 V minimum breakdown threshold. At 104 V clamping voltage, the downstream circuit sees a defined overvoltage ceiling during the surge event — the downstream IC or rail stays within its abs-max rating if the transient energy is within the diode's rated 1.5 kW peak pulse capacity. ## Peak pulse ratings — 1.5 kW and 14.6 A at 10/1000 µs At this waveform, the 14.6 A peak pulse current is what the diode must conduct during the event — a faster waveform (8/20 µs) with the same clamped voltage would pull a higher peak current, so the 14.6 A figure is specific to this test condition. ## DO-214AB SMC package and surface-mount integration Available in Tape & Reel and Cut Tape packaging — the Cut Tape option suits NPI prototyping runs where a full reel is overkill.
