U-MOSIV MOSFETs Toshiba U-MOSIV MOSFETs are offered in logic-level gate drive, low-voltage gate drive, and 10V gate drive variants in N-channel and P-channel polarity. The U-MOSIV MOSFETs offer low drain-source ON-resistance and low leakage current. These devices are offered in through-hole and surface mount packages and are ideal for motor driver, DC-DC converter, and switching voltage regulator applications.
