1. Device Overview
Manufacturer: Infineon Technologies Type: N-channel Power MOSFET Package Type: D2PAK Maximum Voltage Rating: 55V Maximum Continuous Drain Current (Id): 120A Rds(on): 20mΩ (at Vgs = 10V)2. Pinout and Package
The IRF5210PBF uses the D2PAK package, which is a surface-mount type with 3 pins for electrical connections.
Pin Number Pin Name Description 1 Gate (G) Gate input for controlling the MOSFET. Connect to a voltage source for switching. 2 Drain (D) Drain terminal, where the load is connected and current flows out of the MOSFET. 3 Source (S) Source terminal, where current flows into the MOSFET from the ground.3. Pin Function Description
Pin 1 (Gate):
The gate controls the switching behavior of the MOSFET. It requires a positive voltage relative to the source to turn on the MOSFET, allowing current to flow from drain to source. A negative voltage will turn off the MOSFET.
Gate Threshold Voltage (Vgs(th)): Typically 1-2V, below which the MOSFET will not fully turn on.
The gate is capacitive and should be driven by a proper voltage signal, usually from a gate driver circuit.
Pin 2 (Drain):
The drain is the terminal where the MOSFET's output current is directed to the load.
This pin must be connected to the load or the high-voltage side of the circuit. The current flows from the drain to the source when the MOSFET is conducting (i.e., turned on).
Pin 3 (Source):
The source is where the current flows into the MOSFET. This pin is typically connected to ground in a common-source configuration.
The voltage between the source and drain is essential for determining the operation of the MOSFET.
