Diagrams for Calculating the Virtual Junction Temperature Ripple of Semiconductor Devices

Diagrams for constant pulse current with rectangular and sinusoidal wave forms were calculated. They are designed to calculate the difference between virtual junction temperature atthe end and at the beginning of current pulse. The described method is valid for all semiconductor devices whose thermal circuit can be modeled electrically by serial RC-pair connection whose forward characteristic can be approximated by threshold voltage and slope resistance. The use of diagrams is illustrated.
