The short circuit protection of the Evaluation Driver Board basically relies on 2-level Turn-off function already
implemented in the TD350. Thanks to this operation mode, the collector-emitter overvoltage, which is a result
of the stray inductance and the collector current slope, is limited
the second level of the turn-off voltage. If the stray inductance is not higher than 30µH the 2ED100E12-F can
switch-off the IGBT safely. If L

off circuit, during switching-off under short circuit condition are shown on Figure 6c.

Note that the 2-level Turn-off on the Evaluation Driver Board is always enabled, therefore the propagation
