WebOct 7, 2013 · To use a MOSFET as a switch, you need to ensure that the gate-source voltage (Vgs) is higher than the source voltage. When the gate is connected to the source (Vgs=0), the MOSFET remains off. Take the IRFZ44N, a “standard” MOSFET, as an … Webbehaves like a capacitor. Conversely, switches such as triacs, thyristors and bipolar transistors are “current” controlled, in the same way as a PN diode. 2.2 Driving a gate As shown in figure 2, driving a gate consists of applying different voltages: 15V to turn on the device through S1, and 0V to turn off the device through S2.
