Voltage Grade Table Voltage Grade V DRM V DSM V RRM V RSM V D V R V V DC V 8 8 9 56 1 1 11 7 12 12 13 81 2. Extension of Voltage Grades This report is applicable to other voltage grades when supply has been agreed by Sales/Production. 3. De-rating Factor A blocking voltage de-rating factor of.13%/ C is applicable to this device for T j below 25 C. 4. Repetitive dv/dt Standard dv/dt is 1V/µs. 5. Snubber Components When selecting snubber components, care must be taken not to use excessively large values of snubber capacitor or excessively small values of snubber resistor. Such excessive component values may lead to device damage due to the large resultant values of snubber discharge current. If required, please consult the factory for assistance. 6. Rate of rise of on-state current The maximum un-primed rate of rise of on-state current must not exceed 3A/µs at any time during turnon on a non-repetitive basis. For repetitive performance, the on-state rate of rise of current must not exceed 15A/µs at any time during turn-on. Note that these values of rate of rise of current apply to the total device current including that from any local snubber network. 7. Gate Drive The nominal requirement for a typical gate drive is illustrated below. An open circuit voltage of at least 3V is assumed. This gate drive must be applied when using the full di/dt capability of the device. I GM 4A/µs I G t p1 The magnitude of I GM should be between five and ten times I GT, which is shown on page 2. Its duration (t p1 ) should be 2µs or sufficient to allow the anode current to reach ten times I L, whichever is greater. Otherwise, an increase in pulse current could be needed to supply the necessary charge to trigger. The back-porch current I G should remain flowing for the same duration as the anode current and have a magnitude in the order of 1.5 times I GT. 8. Computer Modelling Parameters Data Sheet.
