virtual-junction temperature; internal equivalent temperature (TJ; TVJ)

(1) A temperature representing the temperature of the junction(s) calculated on the basis of a simplified model of the thermal and electrical behavior of the semiconductor device.

NOTE The term "virtual-junction temperature" is taken from IEC standards. It is particularly applicable to multijunction semiconductors and is used to denote the temperature of the active semiconductor element when required in specifications and test methods. The term "virtual-junction temperature" is used interchangeably with the term "junction temperature".

(2) The temperature of the virtual junction.
