MOSFET
Physical form, such as FET transistors. Its function is to boost or lower the voltage.
FET has three legs as well, namely:
• GATE (G) is the input legs
• DRAIN (D) is the output leg
• SOURCE (S) is the source of the foot
Its function is usually used in the circuit switching type power supply to generate a high voltage to drive the transformer.
Her feet are usually sure that when we faced in our direction then FET sequence from left to right foot is GATE, DRAIN, SOURCE.
• Raising the voltage FET Example: K 793, K 1117, K 1214, IRF 630, IRF 730, IRF 620, etc..
• Examples of lowering voltage FET: IRF 9610, IRF 9630, etc (usually 4 digits u / IRF)
