WebEven so, on occasion, designers find the need to operate two MOSFETs in a parallel configuration. Generally speaking, as MOSFETs do not suffer from thermal runaway (as can happen with bipolar devices), this makes paralleling them easier. As MOSFETs are voltage-driven, they simply need a stable and uniform voltage.
