531X306LCCBAG3 Reduce activation loss

The turn-on process of 531X306LCCBAG3 is greatly affected by its gate trigger pulse. Strong trigger pulses can reduce the turn-on time, promote the simultaneous turn-on of series devices, and also reduce turn-on losses, enhancing its di/dt endurance. Therefore, it is necessary to apply synchronous and extremely steep trigger pulses to the series thyristors, with a trigger current amplitude of IGM=4-10 IGT and a trigger current rise time tr of less than 1 microsecond. Due to the fact that the blocking, opening, and recovery characteristics of 531X306LCCBAG3 vary with the temperature of the chip, ensuring synchronous temperature changes at any state and time during the operation of the series thyristor is the basis for ensuring its reliable voltage equalization.

Therefore, it is necessary to adopt the method of using the same heat dissipation body for series devices to ensure the consistency of device temperature.The performance and reliability of 531X306LCCBAG3 are closely related to the operating junction temperature of the device. Under normal use, the junction temperature is generally less than 80 degrees Celsius. If the heat dissipation is poor, it will have a significant impact on the lifespan of the tube core. Practice has proven that after replacing the core of the 531X306LCCBAG3 thyristor heat sink, the heat dissipation effect is significantly reduced, especially after replacing it three or four times, some are no longer usable at all.
