Reverse Recovery Double-Pulse Test Setup

Reverse Recovery tests characterize the body diode in the High-Side device on

the DUT Test Module. 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.

This DPT test uses the following Test Module and Oscilloscope Probes:

Keysight Double-Pulse Test Fixture Installation and Use Guide

– Any Isolated Keysight Low-Side and matching Isolated High-Side Gate

Drive Module.

– Either the PD1000-60901 DUT Module for TO-247 3-pin devices,

PD1000-60902 DUT Module for TO-247 4-pin devices or the

PD1000-62401 DUT Module for D

– N2819A 10:1 Differential Oscilloscope Probe for measuring Gate Current,

– PD1000-60002 Protection Probe for measuring I

– N2873 10:1 Standard Oscilloscope Probe for measuring V

Low-Side Gate Drive Module.

– 10076C 100:1 High Voltage Probe for measuring V

– IMPORTANT: Remove the PD1000-66505 Clamp Module before running a

Standard or Reverse Recovery SPT Test.

When installing or removing the PD1000-66505 Clamp Module,

you must cycle power on the PD1500A rack in order for the

change to be discovered.
