VMOS (V-MOSFETS)

A VMOS is an enhancement MOSFET that can handle much higher drain currents than standard E-MOSFETS (Enhanced-MOSFETS). The "CURRENT" capability of a VMOS transistor results from its physical make-up or construction. The V-MOSFET has a "WIDER CHANNEL" than other E-MOSFETS. The "WIDER CHANNEL" allows a higher "DRAIN CURRENT" to be generated ata given value of Vgs or "source gate voltage" Also, another advantage of the VMOSFET is that it is not susceptible to thermal runaway. The VMOS has a positive temperature coefficient, which means that the channel resistance increases when temperature increases.

Therefore V-MOSFETS can be used in high-power applications where standard MOSFETS cannot be used.
