DTMOSVI MOSFETs Toshiba DTMOSVI MOSFETs offer a low drain-source on-resistance of 0.033Ω (typical), a drain-source voltage of 650V, and a drain current of 57A. The DTMOSVI MOSFETs offer high-speed switching properties with lower capacitance. These MOSFETs are ideal for use in switching power supply applications.
