• Analog signal processing- the 2N7002-D87Z can be used for signal processing, including signal conditioning, isolation, and amplification.
• Load Switching- this MOSFET can be used for low-power current and voltage switching with near-zero voltage drop and extremely low contact resistance.

Working Principle

The 2N7002-D87Z is a type of MOSFET (Metal Oxide Semiconductor Field Effect Transistor). It works by using a voltage to control the current flow through a semiconductor channel. It is an enhancement mode MOSFET, which means that when the gate voltage (Vgs) is applied, the current is controlled according to the applied voltage. It is also an n-channel MOSFET, meaning that the current flows from the source to the drain when the MOSFET is in the on state.

When there is no voltage applied to the gate, the MOSFET is in the off state, and no current flows. As the gate voltage is applied beyond the gate threshold voltage, the MOSFET will enter the linear region and current begins to flow. As the gate voltage reaches the drain source voltage (Vds), the current reaches its maximum and the MOSFET is in the saturation region.

The 2N7002-D87Z features a low gate threshold voltage, meaning that it can be easily switched on and off with low voltages. It also features a low drain-source on-state resistance and high breakdown voltage, making it suitable for controlling large currents and voltages.

Conclusion

The 2N7002-D87Z MOSFET is a versatile and reliable device that can be used in a variety of different applications. Its low gate threshold voltage, low on-state resistance, and high breakdown voltage make it particularly well-suited for driving loads, protection circuits, and load switching. It is an ideal solution for motor control, analog signal processing, and switching circuits.
