Active production — 36V rail protection in DO-214AC
With a peak pulse power rating of 500W (10/1000µs waveform) and a clamping voltage of 58.1V at 8.6A peak pulse current, it protects downstream components from surges up to that energy level. The 36V reverse standoff voltage means it does not conduct during normal 36V operation, only clamping when the line exceeds the 40V minimum breakdown threshold.
The minimum breakdown voltage is 40V, and the maximum clamping voltage is 58.1V. This 18V window between the rail and the clamp sets the voltage stress the load must survive — a 36V-rated capacitor or IC on the same net should be rated for at least 60V to avoid avalanche failure during a surge. The unidirectional channel is typical for DC rail protection; it clamps positive transients and conducts forward like a Schottky on negative spikes, which is acceptable for most DC supplies.
