The SI4848DY-T1-GE3 is a power MOSFET produced by Vishay that operates with a drain-source voltage (VDS) of up to 150V and has a current rating of 3.7A and a power dissipation of 3.0 Watts. It has an average on-state resistance (RDS(on)) of 85mohm @ 10V. This part is based on the trench MOSFET technology which is used to decrease RDSon, reduce the capacitance of the device, reduce the cost and improve power efficiency. It features a low gate charge and low input capacitance which makes it suitable for fast switching applications such as server, automotive and power supply applications.
