## Overview of IRFP064VPBF The **IRFP064VPBF** is a high-power N-Channel enhancement mode MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by Infineon (formerly International Rectifier). It is primarily designed for high-speed switching and power conversion applications. --- ### 1. Key Technical Specifications The following table outlines the absolute maximum ratings and primary characteristics of the device: | Parameter | Symbol | Typical Value | Unit | | :--- | :--- | :--- | :--- | | **Drain-to-Source Voltage** | $V_{DSS}$ | 60 | Volts | | **Continuous Drain Current** | $I_D$ | 110* | Amperes | | **Static Drain-to-Source On-Resistance** | $R_{DS(on)}$ | 0.0055 (5.5mΩ) | Ohms | | **Total Gate Charge** | $Q_g$ | 170 | nC | | **Power Dissipation** | $P_D$ | 250 | Watts | | **Operating Temperature** | $T_j$ | -55 to +175 | °C | *\*Note: Current may be limited by the package type; always refer to thermal dissipation limits.* --- ### 2. Physical Characteristics - **Package Type:** TO-247AC. This is a through-hole package designed for high power dissipation, often requiring a heatsink. - **Lead Finish:** "PBF" indicates that the part is **Lead-Free (Pb-Free)** and RoHS compliant. - **Pinout:** 1. **Gate (G):** Controls the switching of the MOSFET. 2. **Drain (D):** The output terminal connected to the load. 3. **Source (S):** Typically connected to the ground or negative rail. --- ### 3. Core Features and Benefits - **Ultra-Low On-Resistance:** The 5.5mΩ resistance minimizes power loss due to heat during the "ON" state, increasing efficiency. - **High Speed:** Optimized for fast switching, making it suitable for high-frequency PWM (Pulse Width Modulation) circuits. - **Ruggedness:** Fully avalanche rated, meaning it can handle transient voltage spikes without immediate failure. - **Logic Level Compatibility:** While best driven at 10V, it can begin conducting at lower gate voltages. --- ### 4. Typical Applications The IRFP064VPBF is commonly found in the following electronic circuits: 1. **DC Motor Control:** Used in H-Bridge configurations for heavy-duty motors. 2. **Inverters:** Converting DC battery power to AC power. 3. **SMPS (Switched-Mode Power Supplies):** Acting as the main switching element for high-current power bricks. 4. **Uninterruptible Power Supplies (UPS):** High-current battery switching. 5. **Solar Charge Controllers:** Managing the high current coming from solar panels. --- ### 5. Simple Implementation Example (Pseudo-Circuit) To turn the MOSFET on, a voltage ($V_{GS}$) must be applied between the Gate and Source. ```cpp // Logic for driving a Gate Driver for the IRFP064V if (Current_Demand > 0) { digitalWrite(GATE_DRIVER_PIN, HIGH); // Output 10V to Gate } else { digitalWrite(GATE_DRIVER_PIN, LOW); // Pull Gate to Ground (0V) } ``` ---
