IEVref: 521-05-14 ID: Language: en Status: Standard Term: virtual temperature Synonym1: internal equivalent temperature (of a semiconductor device) [Preferred] Synonym2: Synonym3: Symbol: 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: ${T}_{\text{j}}={T}_{\text{case}}+\frac{P}{{R}_{\text{th}}}$ or ${T}_{\text{j}}={T}_{\text{amb}}+\frac{P}{{R}_{\text{th}}}$ Publication date: 2002-05 Source: Replaces: Internal notes: 2016-06-23: Subscripts corrected to upright in accordance with reply from Jean Schwob.
