Product introduction:

Product Introduction

STB70NF03LT4-VB is a single N-channel MOSFET in TO263 package, designed for low voltage and high current applications. With a maximum drain-source voltage (VDS) of 30V and a maximum drain current (ID) of 98A, this MOSFET is suitable for power conversion systems that require high frequency, high efficiency and low power consumption. STB70NF03LT4-VB uses Trench technology and has extremely low on-resistance (RDS(ON) = 2.7mΩ @ VGS = 4.5V, RDS(ON) = 2.4mΩ @ VGS = 10V), effectively reducing power loss and improving system efficiency. It is widely used in high-efficiency power supplies, drive circuits and low-voltage and high-current switching systems, and is an ideal switching element in high-performance devices.
