Back to previous pageProduct introduction：
1. **Product Introduction:**
SSN3139K-VB is a single P-channel MOSFET in SOT723-3 package, designed for low voltage, high efficiency switching power supplies and battery management systems. The maximum drain-source voltage (VDS) of this MOSFET is -20V, the gate-source voltage (VGS) is ±20V, and the threshold voltage (Vth) is -0.45V. Its low on-resistance (RDS(ON)) enables it to have low power consumption and high efficiency during operation, especially when VGS = 10V, the on-resistance can be reduced to 380mΩ, thereby reducing energy loss. SSN3139K-VB can provide a maximum drain current (ID) of -0.78A, which is suitable for low power electronic devices for regulating switching current. Its Trench technology enables it to have a fast switching response, suitable for miniaturization and low power electronic applications.
