ASDM20N90Q-R

The ASDM20N90Q-R is a high-performance N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Ascend. This component is designed for applications requiring efficient power management and switching capabilities.

Key Features:

1. Voltage Rating: The ASDM20N90Q-R has a maximum drain-source voltage (V_DS) of 900 volts, making it suitable for high-voltage applications. This allows it to handle significant voltage spikes without failure.

2. Current Rating: It can handle a continuous drain current (I_D) of up to 20 amperes, which is ideal for various power electronics applications, including power supplies, motor drives, and inverters.

3. R_DS(on): The on-resistance (R_DS(on)) is low, typically in the range of a few ohms, which minimizes power loss during operation. This characteristic is crucial for enhancing efficiency and reducing heat generation in high-current applications.

4. Gate Threshold Voltage: The gate threshold voltage (V_GS(th)) is designed to be low, allowing for easy drive with standard logic levels. This feature ensures that the MOSFET can be turned on and off efficiently with minimal gate drive power.

5. Package Type: The ASDM20N90Q-R is typically housed in a TO-220 package, which provides good thermal performance and allows for easy mounting on heatsinks. This package design is favored for its ability to dissipate heat effectively, ensuring reliable operation under load.

6. Switching Speed: The device exhibits fast switching characteristics, making it suitable for high-frequency applications. This is particularly beneficial in applications such as switch-mode power supplies (SMPS) and DC-DC converters.

7. Thermal Characteristics: The MOSFET is designed to operate over a wide temperature range, with a maximum junction temperature (T_J) of up to 150°C. This robustness allows it to function reliably in demanding environments.

8. Applications: The ASDM20N90Q-R is widely used in various applications, including:

   • Power supplies (AC-DC and DC-DC converters)
   • Motor control circuits
   • Lighting control systems
   • Renewable energy systems (like solar inverters)
   • Industrial automation
