           A critical issue with all semiconductor devices is junction temperature (TJ). TJ must be kept below its maximum rated value,typically 150°C. The lower the junction temperature the better.The thermal circuit shown below allows temperature to be estimated with simple calculations. The temperature rise acrosseach interface is equal to the total power dissipated in the device times the thermal resistance (PD • q). An estimate of the junctiontemperature can be calculated using the following formula:
