ThunderFET 60 V to 100 V n-channel TrenchFET® power MOSFETs devices offer on-resistance ratings down to 4.5 V VGS in SO-8 and PowerPAK® SO-8 packages. Utilizing Vishay’s new ThunderFET® technology, devices offer the lowest values of on-resistance. In addition the product of on-resistance and gate charge — a key figure of merit (FOM) for MOSFETs in DC/DC converter applications — several devices are best in class. The ThunderFET power MOSFETs are optimized for primary side switching and secondary side synchronous rectification in isolated DC/DC power supply designs for telecom brick and bus converter applications. The MOSFETs’ 4.5 V rating for on-resistance allows a wide range of PWM and gate driver ICs to be considered. By utilizing 5 V rated ICs, gate driver losses can be reduced and the overall design simplified by eliminating the need for a separate 12 V power rail.
