Vishay Siliconix Si4190DY ThunderFET®
100V Power MOSFETs
Vishay Siliconix Si4190DY ThunderFET® power MOSFETs offer the lowest values of on-resistance in the industry for 100V MOSFETs with 4.5V ratings. The Vishay Siliconix Si4190DY provides on-resistance of 8.8mΩ at 10V and 12mΩ at 4.5V. These ThunderFET power MOSFETs have an industry-best figure of merit (FOM) of 340mΩ-nC at 10V and 220mΩ-nC at 4.5V. The Vishay Siliconix Si4190DY is a TrenchFET® device optimized for primary side switching and secondary side synchronous rectification in isolated DC/DC power supply designs for telecom brick and bus converter applications.
