## 2N60-TF3-R Technical Overview The **2N60-TF3-R** is a high-voltage N-Channel enhancement mode Power MOSFET designed for high-speed switching applications. It is widely used in power supplies, motor controls, and DC-to-DC converters due to its low gate charge and efficient switching characteristics. ### 1. General Specifications The table below summarizes the primary electrical characteristics of the 2N60-TF3-R. | Parameter | Symbol | Value | Unit | | :--- | :---: | :---: | :---: | | Drain-Source Voltage | $V_{DSS}$ | 600 | V | | Continuous Drain Current | $I_D$ | 2.0 | A | | Pulsed Drain Current | $I_{DM}$ | 8.0 | A | | Gate-Source Voltage | $V_{GSS}$ | $\pm 30$ | V | | Static Drain-Source On-Resistance | $R_{DS(ON)}$ | 4.4 | $\Omega$ | | Total Gate Charge | $Q_g$ | 9.0 | nC | --- ### 2. Physical and Package Characteristics The suffix **TF3** typically refers to the package type, while **R** denotes the packing style (e.g., Tape and Reel). * **Package Type:** TO-220F (Full Pack/Isolated). * **Isolation:** The "F" in TO-220F indicates an internally insulated package, meaning the metal tab is covered in plastic. This prevents short circuits to the heatsink without needing an extra mica washer. * **Thermal Resistance:** $R_{\theta JC}$ is approximately $5.0 ^\circ \text{C/W}$. --- ### 3. Pin Configuration The device follows the standard three-pin layout for power MOSFETs: | Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | **Gate** (G) | Controls the flow of current between Drain and Source. | | 2 | **Drain** (D) | The terminal where the current enters (connected to the load). | | 3 | **Source** (S) | The terminal where the current exits (connected to ground). | --- ### 4. Key Features & Applications #### Features * **Low Gate Charge:** Minimizes switching losses and allows for high-frequency operation. * **Ruggedness:** Designed to withstand high energy in the avalanche and commutation modes. * **High Speed:** Fast switching times ($t_{on}/t_{off}$). #### Typical Applications 1. **SMPS (Switching Mode Power Supplies):** Used in the primary stage for AC-DC conversion. 2. **LED Lighting:** Constant current drivers for high-voltage LED strings. 3. **DC-DC Converters:** Efficient voltage regulation in industrial equipment. 4. **Electronic Ballasts:** Used in fluorescent lighting circuits. --- ### 5.
