APT94N60L2C3G belongs to the family of transistors - FETs, MOSFETs, more precisely; it belongs to the Single type of the FETs. It is a general-purpose power MOSFET with excellent switching performance, low on-resistance and high power and thermal dissipations. Generally, MOSFETs (Metal Oxide Semiconductor Field Effect Transistors) are power transistors being known as voltage-controlled transistors, devices that are mainly used for switching. A voltage is used to control the current and result in a very high input impedance.

ET94N60L2C3G is built-in a TO-220AB package and it is suitable for use under low thermal resistance conditions. It has an minimal gate threshold and possesses an RDS(on) of 3 mOhm at 10V with a drain current of 46A. This MOSFET also owns a 150V drain source voltage and a maximum operation temperature of 150°C. Moreover, its maximum Power Dissipation (Tc = 25°C) is 97 W.

The Application field of APT94N60L2C3G MOSFET is the field of motor control, AC/DC converters and resonant converters. In these converters, it is mainly applied for rectifying and switching purpose. Besides, it can also be used in applications such as power supplies, UPS systems and anywhere else power conversion is required.

Now, talking about the working principle of APT94N60L2C3G MOSFET. As its name suggests, MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor. This is a four-terminal device, consisting of drain, source, gate and body. When a voltage is applied between the gate and source terminal, a semiconductor channel with high input impedance is created between drain and source which grants a high current path. This allows the control of electric energy which makes MOSFET suitable for numerous applications.

When normally-off mode is selected, the MOSFET acts as a switch in cutoff state until voltage is applied between the gate and source; when the voltage which is applied exceeds the threshold voltage (Vgs > Vth), the transistor will be switched to the on state. The higher the applied voltage, the greater the electric current become as a result. The electric current stays the same until the voltage decreases below the threshold voltages (Vgs < Vth), upon which the transistor returns to the off state. This make APT94N60L2C3G an ideal element for switching applications such as thyristors.

In the on state, the electric current flowing through the device is limited by the gate resistance which then influences the Power Dissipation of the device itself. The maximum power dissipation is primarily determined by the temperature rating of the device if the voltage across Source and Drain (Vds) is known. If not, the power dissipation should be indicated in the datasheet of the device itself.

The off-state behavior of APT94N60L2C3G MOSFET is nearly symmetrical compared to the on-state behavior. As the voltage decreases below the gate threshold voltage, the electric current through the device is eventually interrupted and the device will return to the off-state. This effectively makes the device be the switch that can be used to control the electric current in switching applications. In other words, the APT94N60L2C3G MOSFET can be used in circuits with low current requirements to avoid over-heating and power loss.

To summarize, APT94N60L2C3G belongs to the family of transistors, FETs- MOSFETs - Singles; is built-in a TO-220AB package; with a minimal gate threshold and an RDS(on) of 3 mOhm and 46A drain current at 10V voltage; 150V drain source voltage - 150°C maximum operation temperature, and 97 W maximum power dissipation. It is mainly applied for motor control, AC/DC converters, resonant converters and power conversion.

Its working principle is that, when a voltage is applied between the gate and source terminal, a semiconductor channel with high input impedance is created between drain and source which grants a high current path, and the electric current through the device is eventually interrupted when the voltage decreases below the gate threshold voltage. This makes it an ideal element suitable for switching applications.
