Back to previous pageProduct introduction：
1. Product Introduction
**SSM9928O-VB** is a dual N-channel MOSFET in TSSOP8 package with common source-common gate configuration, suitable for high-efficiency power management and switch control applications. The maximum drain-source voltage (VDS) of this MOSFET is 20V, and the maximum gate-source voltage (VGS) is ±20V, which can meet the needs of most low-voltage power circuits and high-efficiency switching applications. The threshold voltage (Vth) ranges from 0.5V to 1.5V, ensuring effective conduction at a lower gate voltage.
The on-resistance (RDS(ON)) of this model is 32mΩ (VGS=2.5V) and 22mΩ (VGS=4.5V), which can maintain low power consumption and efficient current conduction even at high current (ID=6.6A). It uses **Trench technology**, which provides extremely low on-resistance and fast switching response, and can achieve better performance in high-efficiency power conversion and switch control. SSM9928O-VB is widely used in power management, battery management and high-efficiency current switching.
