A thyristor has a maximum allowable junction temperature of 120ºC...
°C. This means that the temperature at the junction between the semiconductor layers of the thyristor should not exceed 120°C during operation. If the junction temperature exceeds this limit, the thyristor may be damaged or destroyed. Therefore, it is important to ensure that the thyristor is properly heat-sinked and that the ambient temperature around the thyristor is within the specified range. Additionally, the thyristor should not be subjected to high voltage or current surges, which can also cause the junction temperature to rise rapidly.
