The SE4020B MOSFET is a TO-252 surface-mountable device, manufactured by SINO-IC, used for low- to moderate-power switching applications. It is constructed with a N-Trench MOSFET, which offers a higher voltage protection, higher speed, and higher surge capabilities. The MOSFET has a drain source breakdown voltage of 40V, a continuous drain current of 20A, a threshold voltage of 2V, a gate threshold voltage of 250uA, a on-resistance of 23mΩ at 5A and 10V, and is RoHS compliant.
