Back to previous pageProduct introduction：
1. Product Introduction
**SPB46N03-VB** is a single N-channel MOSFET in TO263 package, designed for low voltage, high current applications. With a drain-source voltage (VDS) of 30V, this MOSFET is ideal for low voltage power conversion and power management systems. Its gate-source voltage (VGS) is ±20V and can carry a drain current of up to 50A. Its on-resistance (RDS(ON)) is very low, 18mΩ at VGS=4.5V and 12mΩ at VGS=10V, which enables it to have very low power loss when operating at high current, thus improving the efficiency of the system. Designed with Trench technology, SPB46N03-VB can provide higher switching speeds and lower conduction losses, making it an ideal choice for power converters, switching power supplies, and high power load control systems.
