super junction MOSFET (SJ-MOSFET)

Super Junction MOSFETs (SJ-MOSFET) are high performance MOSFETs designed for switching higher powers and voltages and are used in voltage converters.

Unlike conventional MOSFETs, SJ-MOSFETs have a much larger pn junction area between source and drain. This leads to an extremely low contact resistance between the mentioned electrodes. This is about 0.1 Ohm in the switched state (on). This low on-resistance results in low heat generation due to power dissipation.

SJ MOSFETs are housed in TO packages (TO-220) and are used in power electronics, power supply devices, motor controls and lighting technology.
