AOD206_030 is a N-channel PowerTrench® MOSFET developed by Fairchild Semiconductor that is designed for low voltage, high current automotive applications. As a MOSFET—Metal-Oxide-Semiconductor Field-Effect Transistor—it is a versatile solution for automotive power switching, providing high levels of efficiency, thermal performance, and system reliability. It is well-suited for applications including powertrain management, system monitoring, motor control, and energy storage.

Electrical Characteristics

The AOD206_030 MOSFET has a typical drain-source on-resistance (RDS (on)) of 0.023 Ohm, a gate-source voltage range of +/-20V (VGS), and a maximum drain current of 30A (ID). It operates at levels of up to 100V for drain-source voltage (VDS), and has a maximum power dissipation of 4.5 W.

The transition frequency (fT) of this MOSFET is 44 GHz, with a typical threshold voltage of 1V. It also has a typical low gate charge (Qg) of 15 nC, meaning it requires minimal input from the gate in order to turn on or off. This is an important factor for its applications, as it helps ensure fast switching, even with heavy loads.

Applications

The AOD206_030 was designed with automotive applications in mind, and is used in powertrain servers, monitoring systems, motor control circuits, and energy storage systems. Its low RDS(on) and high current makes it ideal for power switching, while its low threshold (Vt) and low gate charge (Qg) enable fast switching speeds. This MOSFET is also adapted to be used in an environment with wide ambient and cold-crank temperatures.

Due to its wide range of features, the AOD206_030 is a great fit for automotive dynamic systems such as powertrain management, motor starters, acceleration control, and spark generation. Its applications reach beyond the automotive field, and it is also used in white goods, fans, and other small appliances.

Working Principle

The AOD206_030 works in a way similar to other MOSFETs. In basic terms, it is an “electronic switch”, whose drain and source are connected to a voltage source. When a gate voltage is applied, electrons from the gate move into the channel, allowing current to flow between the drain and source. When the gate voltage is removed, current is blocked.

Essentially, the AOD206_030 MOSFET uses capacitance, rather than resistance, to control the flow of current. Because the gate terminal is insulated from the main body of the MOSFET, it can be used to control current without wasting energy as heat. This makes it very efficient when compared to other transistors and more suitable for high-frequency switching applications.

Conclusion

The AOD206_030 is a versatile MOSFET that offers advantages in applications that require fast switching and low power consumption. Its low threshold voltage, low gate charge, and high drain current enable high levels of efficiency, and its wide range of applications make it a great fit for a wide range of automotive and consumer applications.
