APT7F100B Application Fields and Working Principle

The APT7F100B is an N-channel MOSFET which is most commonly used in power conversion applications. Its high current-handling capabilities, low gate charge and high linearity make it ideal for use in consumer, industrial and automotive applications. Additionally, its low-voltage gate threshold makes it suitable for low-noise applications such as in audio and video circuitry.

The working principle of a MOSFET is based on two fundamental properties. The first is the conductivity modulation which occurs when a voltage is applied to the gate (G) of the MOSFET, resulting in the conduction of current between the source (S) and the drain (D) terminals. The other is the pinch-off effect, which results in a decrease in the current flowing between the source and the drain when the applied gate-source voltage is increased beyond a certain threshold. The APT7F100B has a low-voltage gate threshold, so it is most suitable for use in low-noise applications.

The APT7F100B is optimized for use in power conversion applications, as its high-current, low-noise operation makes it an ideal choice for audio and video circuitry. It is also suitable for use in consumer, industrial and automotive markets due to its high linearity, high input impedance, low gate charge and ESD protection up to 2000V. Additionally, its junction temperature of 175 C makes it a reliable and durable choice for these applications.
