The model number "I RF R024NTRPBF" corresponds to a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) produced by Infineon Technologies, a well-known brand in the semiconductor industry. This specific part is designed for switching and Power applications, typically used in power management circuits, voltage regulation, and motor control.
Package Type:
The IRFR024NTRPBF comes in a TO-220 package, which is a standard package for discrete power semiconductors. This package type is used for components that require good heat dissipation and can handle higher currents.Pin Function Specifications:
The IRFR024NTRPBF is a 3-pin MOSFET device, and the pinout is as follows:
Pin Number Pin Name Pin Description 1 Drain (D) The Drain pin is the terminal through which current flows out of the MOSFET. It is connected to the load in the circuit. 2 Gate (G) The Gate pin is used to control the switching of the MOSFET. By applying a voltage to this pin, you create an electric field that controls the flow of current between the Drain and Source. 3 Source (S) The Source pin is the terminal through which current enters the MOSFET. It is typically connected to the ground or negative rail in a circuit.Circuit Principle Instructions:
The IRFR024NTRPBF operates as an N-channel MOSFET, meaning the current flows through the device from the Drain to the Source when the Gate is properly driven. The key features and principles of operation are:
When a positive voltage is applied to the Gate relative to the Source (typically above the threshold voltage), the MOSFET becomes conductive, allowing current to flow from the Drain to the Source. When the Gate voltage is zero or below the threshold, the MOSFET remains off, and no current flows between the Drain and Source. The Source is usually connected to the negative rail or ground in a typical circuit. The Drain is where the load is connected, and current flows out of this pin. The Gate controls the switching and the speed at which the MOSFET turns on or off.Pin Function FAQ:
