The FDS8934A is a high performance array of enhancement mode FETs from Fairchild Semiconductor. It is designed for applications such as load switching. It consists of four Logic circuit protection FETs in a single package, providing high current load switching and low load current on the gate. Each FET has a separate gate, drain and source, allowing for individual channel control.

The FDS8934A has an operating temperature range of -55°C to 150°C, a maximum drain-source breakdown voltage of 14V and a maximum drain-source on-state resistance of 1.6 Ohm. The FDS8934A also features protection circuitry including over voltage, over current and over temperature protection. The four FETs are configured in a single package, with a total power dissipation of 8W. The max gate threshold voltage is 3.5V, and the gate source leakage current is 1uA.

The working principle of the FDS8934A is the same as any other enhancement mode FET. When a voltage is applied to the gate, it creates a channel between the source and drain and allows electrons to flow. This current flow is dependent on the voltage applied to the gate and the channel resistance between the drain and source. When the voltage on the gate is turned off, the channel returns to its original current state and electrons cannot flow. The FDS8934A can be used for load switching based on this principle.

The FDS8934A can be used in a variety of applications from high current load switching and protection, to signal conditioning and level shifting. It can be used in automotive, industrial, home automation and medical device applications. It is an ideal solution for applications such as motor control, power supply protection and overcurrent protection, as well as a wide range of signal processing applications.

The FDS8934A is a versatile and highly reliable array of enhancement mode FETs for many different applications. It provides high current load switching and low gate transimpedance, as well as protection from over voltage, over current and over temperature. It is also able to operate in a wide temperature range from -55°C to 150°C. It is both cost effective and power efficient, making it an ideal choice for many different applications.
