Definition: theoretical temperature which is based on a simplified representation of the thermal and electrical behaviour of the semiconductor device

NOTE 1 – The virtual temperature is not necessarily the highest temperature in the device.

NOTE 2 – Based on the power dissipation and the thermal resistance or impedance that corresponds to the mode of operation, the virtual junction temperature can be calculated from the formula:
