Application  
i
Protection of thyristors against overvoltages in forward  
direction.  
Thyristor  
BOD  
VBO (TVJ) = VBO, 25°C [1+KT(TVJ - 25°C)]  
VD  
Calculation example  
a. The maximum junction temperature shall be  
calculated for a module IXBOD 1 -30R at an  
ambient temperature Ta = 60 °C, an exponentially  
decaying current ITM = 40A, a pulsewidth tp = 2 µs,  
an operating frequency f = 50 Hz and natural  
convection. From the diagram Fig. 6 the energy per  
pulse is obtained:  
b. If following these steady-state conditions an  
overload for 1 minute occurs with ITM= 60 A and a  
pulse-width tp = 4 µs at the same operating  
frequency f = 50 Hz, then the resulting maximum  
junction temperature is calculating as follows:  
TVJmax2 = TVJmax1 + (Ep2-Ep1) • n • f •ZthJA(t) + Kp • (Ep2-Ep1)  
The diagrams Fig. 11 and Fig. 8 show  
Ep1 = 6 x 10-3 Ws  
For a module IXBOD1-30R the number of single  
IXBOD elements is:  
Ep2= 14x10-3 Ws  
n = 3  
ZthJA(t = 1min) = 12K/W  
At natural air cooling the thermal resistance junction  
to ambient amounts to (Fig.8):  
From what follows:  
RthJA = 20K/W  
TVJmax2 = 82.2 + 14.4 + 5,6 = 102.2 °C  
and the unknown temperature can be calculated as:  
TVJmax1 = Ta + n • f • Ep • RthJA + Kp • Ep  
TVJmax1 = 60 + 18 + 4.2 = 82.2°C  
which is allowed because the maximum admissible  
junction temperature TVJM = 125 °C.
