Lear more about paralleling power MOSFETs

There is a continuous need for higher power capability in most applications today. In some applications, a single MOSFET is not enough. In these applications, designers must share the current load among multiple MOSFETs in parallel.

Connecting MOSFETs in parallel while ensuring a rugged design which includes safe operation and reliability is a challenge. Current sharing among devices in parallel is often not well understood and can cause unexpected system failures in the field if not done properly.

Infineon has developed collaterals to explain these challenges and offer solutions to help designers apply the correct methodology in designing power converters.

Paralleling becomes more of a challenge under switching conditions and more so as frequency increases. When paralleling MOSFETs, it is essential to understand and ensure proper current balance among the MOSFETs, comprehend MOSFET parameters affecting current sharing, conduction losses, switching losses, and the importance of gate threshold voltage on the device temperature.
