Working Principle of IRLU7821PBF

A P-channel Hexfet Power MOSFET is an insulated-gate Field Effect Transistor or FET. The IRLU7821PBF is an N-channel MOSFET and uses N-type semiconductor material to create an array of electronically isolated channels. It has a single gate terminal and multiple drains and sources. The P-channel Hexfet Power MOSFET is characterized by its low on-state resistance (RDS(on)) and fast switching speeds.

The P-channel Hexfet Power MOSFET is a three-terminal device that has a gate input, a source terminal, and a drain terminal. In operation, the gate input acts as a control signal to the device, either allowing or limiting the current flow from the source to the drain. When a negative voltage is applied to the gate, the result is an ON state, in which current flows from the source to the drain. When no gate voltage is applied, the device is in an ideal OFF state.

The IRLU7821PBF has a threshold voltage of -5 V, which is the voltage that needs to be applied to the gate in order to switch the device ON. The device also has a maximum drain-source voltage rating of -20V and a peak drain current of 20A. The drain-source on-resistance (RDS(on)) is 0.045 Ω and the gate-source threshold voltage can range from -5 V to -7 V.

The IRLU7821PBF has the capability for fast slew rate, low input capacitance and a built-in reversed diode on the drain lead for ESD protection (electro-static discharge). This device is ideal for a variety of applications, including switch mode power supplies, motor control and high-speed switching circuits.
