Notes on Ratings and Characteristics
1.0 Voltage Grade Table
2.0 Extension of Voltage Grades
This report is applicable to other voltage grades when supply has been agreed by Sales/Production.
3.0 De-rating Factor
A blocking voltage de-rating factor of 0.13%/°C is applicable to this device for Tj below 25°C.
4.0 Repetitive dv/dt
Standard dv/dt is 1000V/µs.
5.0 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.
6.0 Rate of rise of on-state current
The maximum un-primed rate of rise of on-state current must not exceed 400A/µs at any time during turn-
on on a non-repetitive basis. For repetitive performance, the on-state rate of rise of current must not
exceed 200A/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.
7.0 Gate Drive
The nominal requirement for a typical gate drive is illustrated below. An open circuit voltage of at least 30V
is assumed. This gate drive must be applied when using the full di/dt capability of the device.
The magnitude of IGM should be between five and ten times IGT, which is shown on page 2. Its duration
(tp1) should be 20µs or sufficient to allow the anode current to reach ten times IL, whichever is greater.
Otherwise, an increase in pulse current could be needed to supply the necessary charge to trigger. The
‘back-porch’ current IG should remain flowing for the same duration as the anode current and have a
magnitude in the order of 1.5 times IGT.

8.2 Calculating VT using ABCD Coefficients
The on-state characteristic IT vs. VT, on page 6 is represented in two ways;
(i) the well established VT0 and rT tangent used for rating purposes and
(ii) a set of constants A, B, C, D, forming the coefficients of the representative equation for VT in
terms of IT given below:
The constants, derived by curve fitting software, are given below for both hot and cold characteristics. The
resulting values for VT agree with the true device characteristic over a current range, which is limited to
that plotted.
