SM4303PSUC-VB Product details
Back to previous pageProduct introduction：
1. Product Introduction:
SM4303PSUC-VB is a single P-channel MOSFET in TO251 package, designed for low and medium voltage power management applications. Its maximum drain-source voltage (VDS) is -30V, suitable for switching in negative power systems or on the negative side of the power supply. The threshold voltage (Vth) of this MOSFET is -2.5V, which can stably conduct at a lower gate-source voltage. The RDS(ON) is 8mΩ at VGS=10V and 10.8mΩ at VGS=4.5V, showing extremely low on-resistance and reducing power loss. ID can reach up to -70A, suitable for control and switching applications of high current loads. Adopting Trench technology, it has good switching performance, low conduction loss and higher energy efficiency, suitable for high-performance power conversion and current regulation applications.
