Reverse Recovery Test

Reverse Recovery tests characterize the body diode in the DUT device. If a diode is conducting in a forward direction and immediately switched to a reverse bias condition, the diode continues to conduct in the reverse bias state for a very short time as the forward voltage bleeds off. The current through the diode is fairly large in the reverse direction during this small recovery time.

After the carriers are flushed and the diode is acting as a normal blocking device in the reverse bias condition, the current flow drops to normal leakage levels.

There are multiple standards for reverse recovery measurements.
