SI4403CDY-T1-GE3-VB Product Introduction
**SI4403CDY-T1-GE3-VB** is a single P-channel MOSFET in SOP8 package, designed for low voltage, high current switching applications. Its maximum drain-source voltage (V_DS) is -20V, suitable for use in negative power supply and reverse current control circuits. The device has a low threshold voltage (V_th) of -0.6V, so it can be turned on and perform effective switching operations at a lower gate-source voltage.
**SI4403CDY-T1-GE3-VB** has an on-resistance (R_DS(ON)) of 21mΩ at V_GS=2.5V and 15mΩ at V_GS=4.5V, which means it is able to provide very low power losses. The maximum drain current (I_D) is -13A, making it suitable for switching applications with high current loads. Using Trench technology, it can provide low-loss, high-efficiency switching performance at higher frequencies, suitable for various power management and current control circuits.
