Example of a circuit
A simple emergency triggering circuit.
T
: Thyristor
R1 : Current limiting resistance (0 - 200 Ω)
D1 : Series-diode (fast recovery diode)
D3 : Protection diode
D
: Zener diode, typical V : 3-6 V

Z
R , C : Protection against parasitic triggering;

recommended values:
R2 : 100 - 1000 Ω
C : 22 - 47 nF
2
R3, C3 : Snubber network of the thyristor
Notice
1. A IXBOD element has a maximum reverse
blocking voltage of 10V.
2. For higher reverse voltages a fast, soft recovery
diode must be connected in series (Fig. 9).
This diode must fulfill the conditions of Fig. 10.
