Reverse avalanche capability
In operation with an antiparallel freewheeling diode, the GTO reverse voltage VR may exceed the rate value VRRM
due to stray inductance and diode turn-on voltage spike at high di/dt. The GTO is then driven into reverse
avalanche. This condition is not dangerous for the GTO provided avalanche time and current are below 10 µs
and 1000 A respectively. However, gate voltage must remain negative during this time. Recommendation : VGR =
10… 15 V.
