Back to previous pageProduct introduction：
1. Product Introduction
IRFS4321PBF-VB is a high-performance N-channel MOSFET in TO-263 package. Designed for high voltage and high current applications, this MOSFET has a maximum drain-source voltage (VDS) of 150V and a maximum drain current (ID) of 128A, making it suitable for use in high power environments. IRFS4321PBF-VB uses advanced Trench technology to provide low on-resistance (RDS(ON)), which is 7.5mΩ at a VGS of 10V. This design reduces power consumption and heat, and improves system efficiency and reliability.
