JAN2N7225 Application Field and Working Principle

When it comes to high power and low noise control, the JAN2N7225 MOSFET is second to none. This popular N-channel MOSFET, also called the JAN2N7225, is constructed using exceptionally rugged technology which allows it to tolerate ESD pulses up to 2 kilovolts. It works well in wide range of hi-frequency switching and as a low-dropout regulator.

Application Field

The JAN2N7225 MOSFET is useful in many kinds of power control applications, such as:

• switching power supplies
• controlling high-voltage loads
• power amplifiers
• AC/DC converters
• DC/DC converters
• motor drives

Additionally, it is well suited for applications such as USB and firewire circuits, low voltage drivers, audio stages, power and drivers for LCDs, and any additional circuit requiring low noise and high power handling.

Working Principle

The JAN2N7225 is an N-channel MOSFET which controls current by blocking a flow of electrons through a non-conductive gate. This means the JAN2N7225 can easily create an analogue AC signal with low noise and gain accuracy. The MOSFET basically consists of three layers, a gate, drain and source. To apply a voltage to the gate, it must be connected between the drain and source.

The MOSFET can be used as either a linear amplifier or as a switch. It functions as a switch when your relevant parameter is high and low, in which case it can measure a digital value like 0 or 1. Positive voltage applied to the gate below the rated threshold voltage of the MOSFET will slowly open up the gate allowing the electrons to pass through the gate. When there is no voltage applied to the gate, or if the voltage applied is negative, it will keep the gate closed.
