Product Introduction
**SFU9230B-VB** is a single P-channel power MOSFET in TO251 package, designed for high voltage load switch applications. Its maximum drain-source voltage (VDS) is -200V, which is suitable for medium and high voltage negative power supply systems. The maximum gate-source voltage (VGS) of this device is ±20V, which adapts to a wide range of driving voltage conditions. The threshold voltage (Vth) is -2.5V, which means that it can be started at a lower gate voltage, which is suitable for low voltage drive switch applications. The on-resistance (RDS(ON)) is 1200mΩ at VGS=4.5V and 1000mΩ at VGS=10V. Although the on-resistance is relatively large, it still performs well in medium power load applications. The maximum drain current (ID) is -5A, which is suitable for handling medium current applications in negative voltage environments. This MOSFET adopts Trench technology, has good switching characteristics and reliability, and is suitable for negative power management, power conversion, load switching and other fields.
