L3303S-VB Product details
Back to previous pageProduct introduction：
1. Product Introduction
The L3303S-VB is a high-performance single N-channel MOSFET in a TO263 package, designed for medium-low voltage and medium-high current applications. The device has a drain-source voltage (VDS) of **30V**, which can meet the needs of various switching power supplies and power management systems. Its gate-source voltage (VGS) is rated at **±20V**, and the gate threshold voltage (Vth) is **1.7V**, ensuring that it can turn on quickly at a lower voltage. The on-resistance (RDS(ON)) of the L3303S-VB is **18mΩ** at **VGS=4.5V** and **12mΩ** at **VGS=10V**, which enables the device to carry a drain current (ID) of up to **50A**. The use of trench technology not only improves switching performance but also reduces power consumption, making it very suitable for power conversion and other high-efficiency applications.
