CONCLUSION To evaluate the limit before thermal runaway, the maximum value of the reverse current has to be considered. Actually, this parameter is critical for thermal runaway and the worst case must be con-sidered. To evaluate the maximum reverse current of a power Schottky, take the typical value given in figure.
Webloop can cause thermal runaway and damage to the PCB or MOSFETs. For this reason it is important to keep the characteristics of the body diode and the expected reverse current flow in mind when choosing the MOSFET. Schematic Considerations When the first MOSFET turns on, it causes a rapid voltage swing at the source node as it starts to … WebOct 28, 2016 · Hitting a temperature greater than 125C on the VRM with EVGA's design could result in MOSFET failure, effectively triggered by a runaway thermal scenario …
