On one hand, the leakage current of power electronics modules such as IGBTs depends on the temperature. On the other hand, the temperature distribution on the IGBT chips is significantly non-uniform in high current and high voltage power modules where the chip center often suffers a maximum value while border edges and/or corners have a minimum value.

Which temperature of the chip below does affect the leakage current?

  • maximum,
  • minimum,
  • area-weighted average temperature,
  • the temperature of the active area or
  • termination area.
  • 1

  • \$\begingroup\$ Why cannot the leakage be a function of the local temperature at the local portion of the high-voltage junction? \$\endgroup\$ – analogsystemsrf Feb 5 '19 at 15:53
