Product Introduction: W2918-VB
W2918-VB is a high-efficiency N-channel MOSFET in TO262 package, designed for high voltage and high current applications. This MOSFET has a drain-source voltage (VDS) of 100V and can carry a maximum drain current (ID) of 100A. Its on-resistance (RDS(ON)) is 10mΩ at VGS=4.5V and 9mΩ at VGS=10V, which means it can maintain extremely low power loss under high current and high frequency operation. The W2918-VB uses Trench technology to provide lower on-resistance and higher switching speed, thereby improving overall system efficiency and reducing heat generation. This MOSFET is widely used in power management, industrial control, motor drive and other fields that require high voltage and high current processing.
