BS EN IEC 63378-3:2025

Thermal standardization on semiconductor packages. Part 3: Thermal circuit simulation models of discrete semiconductor packages for transient analysis | Status: Current

1 Scope This part of IEC 63378 specifies the thermal circuit network model of discrete (TO-243, TO-252 and TO-263) packages, which is used in the transient analysis of electronic devices to estimate precise junction temperatures without experimental verification. This model is intended to be made and provided by semiconductor suppliers and to be used by assembly makers of electronic devices.
