The AO4821 N-Channel Field Effect Transistor (FET) is a high-voltage device designed for high-volume, low-cost applications. Its low on-resistance, fast switching speed and high reliability make it ideal for applications that require high power and performance. The device features a TO-220-2SO package, which provides excellent thermal conductivity, low inductance and excellent mounting flexibility. It is a robust, reliable and cost-effective solution for power switching and line-level switching in high-voltage applications.
The AO4821 is a Depletion-mode n-channel MOSFET with built-in gate protection, meaning it operates in the reverse bias region and is not susceptible to gate damage caused by static electricity.
The p-channel version of the device (the AO4822) is also available, and both parts have a breakdown voltage of 100 Vds. This means that they are well-suited for applications that require high-voltage switching and can be used in both linear and switching applications. They can also be used as level shifters, and they provide protection against over-current, over-voltage, and over-temperature conditions.
The AO4821 is typically used in dc-dc converter applications, such as automotive inverters, chargers, motor controllers and high-voltage industrial motor control systems. Additionally, it is also used in high-voltage linear and switching applications, such as motor drives, battery chargers, UPS systems and industrial equipment. The device is also used in battery management systems, safety devices, and industrial systems that require high-reliability devices.
The AO4821 operates under the principle of insulated gate control, which uses an applied gate voltage to create a channel between the source and drain. The electrical current then flows between the source and drain, controlled by the amount of applied gate voltage. The device can handle higher power and switching speed because of the insulating layer between the gate and drain.
The device is also protected from over-current, over-voltage and over-temperature conditions. This protection is necessary because dc-dc conversion applications are typically subject to multiple environmental conditions. For example, motor controllers may be subject to extreme temperatures, electrical noise, and high-current spikes at startup. The AO4821 device is protected against these conditions, making it a reliable and cost-effective device for these applications.
In summary, the AO4821 N-Channel Field Effect Transistor is an ideal device for applications that require high power and performance in high-voltage environments. It features low on-resistance, fast switching speed and high reliability, making it suitable for use in both linear and switching applications. Additionally, it is protected from over-current, over-voltage and over-temperature conditions, making it a reliable and cost-effective device for dc-dc converter applications.
