Ⅴ.Control the on-off between source and drain of the gate voltage of FDS6910

FDS6910 is an N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) device whose gate voltage controls the current by controlling the on-off between source and drain.

In a MOSFET, the gate voltage determines the on or off state of the channel. When the gate voltage is lower than the nominal value, the channel is closed and current cannot flow from source to drain. When the gate voltage is higher than the nominal voltage, the channel opens and current can flow from source to drain.

The gate voltage of the FDS6910 can be controlled by external circuitry. When the gate voltage is higher than the minimum voltage, the channel between the source and drain is turned on and current can flow through the channel. At this time, the resistance between the source and drain is very small and can be regarded as a short circuit. When the gate voltage is lower than the nominal voltage, the channel is closed and the resistance between the source and clear electrodes is very large and can be regarded as an open circuit.

Therefore, by controlling the gate voltage of the FDS6910, the on-off between the source and drain can be controlled, thereby realizing power switch and amplifier applications in electronic circuits.
