Transient suppression for 30.8 V rails
The 1.5KE36CA B0G: It clamps transients at 49.9 V maximum while conducting 31 A peak pulse current, protecting a 30.8 V nominal rail from overvoltage events. The DO-201AA axial-lead package suits through-hole assembly on power-supply or I/O boards where a single bidirectional device replaces two unidirectional diodes in anti-series.
Voltage ratings and clamping margin
Reverse standoff voltage is 30.8 V — the rail voltage below which the diode draws negligible leakage. Breakdown occurs at 34.2 V minimum, ensuring the device does not conduct during normal operation on a 30.8 V supply. Clamping voltage at 49.9 V maximum defines the protection ceiling: downstream components must survive this peak during a transient. The 31 A peak pulse current rating (10/1000 µs) gives the surge capacity for industrial or automotive load-dump events.
