    The maximum junction temperature for a thyristor is typically around 125°C to 150°C. However, it is important to note that the actual maximum junction temperature can vary depending on the specific manufacturer and model of the thyristor. It is always recommended to refer to the datasheet provided by the manufacturer for the exact maximum junction temperature specification.
