5SGA 20H4502
Reverse avalanche capability
In operation with an antiparallel freewheeling diode, the GTO reverse voltage
V
R
may exceed the rate
value V
RRM
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 : V
GR
= 10… 15 V.
