WebHowever, this is not the case when the MOSFETS are conducting in the reverse direction through the body diode. The forward voltage of the body diode decreases with a temperature rise and enables more flow of current through it. With time, the current imbalance increases and causes thermal runaway, damaging the MOSFETs in parallel. Webflows because the VGS is not low enough to drive the MOSFET fully OFF, ID will increase as die temperature rises. This thermal runaway effect can ultimately cause MOSFET destruction. Conversely, the designer must consider the upper temperature limit for turning the MOSFET off. At 175 °C a logic level device may conduct channel current at a VGS ...
