FQD5P20TM

The FQD5P20TM is a P-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by ON Semiconductor. This device is designed for high-efficiency switching applications and is particularly suitable for power management in various electronic circuits.

Key Features:

1. Type: P-Channel MOSFET

   • The FQD5P20TM is specifically a P-channel device, which means it conducts when a negative voltage is applied to the gate relative to the source.

2. Voltage Rating:

   • The maximum drain-source voltage (V_DS) is typically rated at -20V. This allows it to handle a range of applications where the voltage does not exceed this limit.

3. Current Rating:

   • The maximum continuous drain current (I_D) is rated at -5A. This makes it suitable for applications that require moderate current handling capabilities.

4. R_DS(on):

   • The on-resistance (R_DS(on)) is low, typically around 0.5 ohms at a gate-source voltage (V_GS) of -10V. This low on-resistance contributes to reduced power losses during operation, enhancing overall efficiency.

5. Gate Threshold Voltage (V_GS(th)):

   • The gate threshold voltage is in the range of -1V to -3V, which indicates the voltage required to turn the MOSFET on. This feature allows for compatibility with various control voltages.

6. Package Type:

   • The FQD5P20TM is available in a TO-220 package, which provides good thermal performance and is suitable for heat dissipation in high-power applications.

7. Applications:

   • This MOSFET is commonly used in power management circuits, including DC-DC converters, motor drivers, and load switches. Its characteristics make it ideal for battery-powered devices and other applications where efficiency is critical.

8. Thermal Characteristics:

   • The device has a maximum junction temperature (T_J) rating of 150°C, allowing it to operate in a wide range of thermal environments.

Electrical Characteristics:

• Input Capacitance (C_iss): Typically around 1,200 pF, which affects the switching speed and drive requirements.
• Output Capacitance (C_oss): Typically around 200 pF, influencing the device's performance in high-frequency applications.
• Reverse Transfer Capacitance (C_rss): Typically around 100 pF, which is important for understanding the device's behavior in switching applications.

Conclusion:

The FQD5P20TM from ON Semiconductor is a versatile P-channel MOSFET that offers a combination of low on-resistance, moderate current handling, and a suitable voltage rating for various power management applications. Its TO-220 package ensures effective heat dissipation, making it a reliable choice for engineers designing efficient electronic circuits.
