Product Introduction: SM1A27PSUB-VB MOSFET
SM1A27PSUB-VB is a unipolar P-channel MOSFET in a TO-251 package, designed for high-efficiency power switching applications. Its maximum drain-source voltage (VDS) is -100V, which is suitable for power supplies and switching circuits that require negative voltage control. This MOSFET has a low on-resistance (RDS(ON) of 120mΩ @VGS=4.5V, 100mΩ @VGS=10V), and can provide good conductivity at a lower gate voltage, suitable for medium and high power load applications. The threshold voltage (Vth) is -2V, ensuring effective switching control at a lower gate voltage. The SM1A27PSUB-VB uses Trench technology to provide excellent switching performance and low conduction losses, making it an ideal choice for power management, inverters, and load switches.
