1. L3803VS-VB MOSFET Product Introduction
L3803VS-VB is a high-efficiency single N-channel MOSFET in TO263 package, designed for medium and low voltage applications. The device has a drain-source voltage (VDS) of 30V and a gate-source voltage (VGS) range of ±20V, which enables stable operation in a variety of electrical environments. The turn-on threshold voltage (Vth) of L3803VS-VB is 1.7V, ensuring that it can be turned on quickly at a lower gate voltage. Using advanced trench technology, the on-resistance (RDS(ON)) of this MOSFET is 2.7mΩ at 4.5V and drops to 2.4mΩ at 10V, and can support a maximum drain current (ID) of up to 98A. Due to its excellent electrical characteristics and reliability, L3803VS-VB is widely used in power management, motor drive and industrial control.
