TESTING ELECTRONIC COMPONENTS WITH MEASURING TOOLS & REPAIR ( 4 )

                                                                        MOSFET
Physical form such as FET transistors. Its function is to raise the voltage or lower voltage.
FET has three legs as well, namely:

• GATE (G) is the input leg
• 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 for generating a high voltage to drive the transformer.

 

His legs are usually already sure that when we faced our FET in the direction of the sequence from left to right foot is GATE, DRAIN, SOURCE.

• Example penaik FET voltage: 793 K, 1117 K, 1214 K, IRF 630, IRF 730, IRF 620, etc..
• Examples of lowering the voltage FET: 9610 IRF, IRF 9630, etc. (usually 4 numbers u / IRF)

 

 • FET UP VOLTAGE
How to measure:
Ohmmeter measurement limit X10 / X1K

 

 

• DOWN VOLTAGE FET
How to measure:
Ohmmeter measurement limit X10 / X1K
