## Overview of the 2N60L-TF3-R The **2N60L-TF3-R** is a high-voltage N-Channel enhancement mode Power MOSFET. It is primarily designed for high-efficiency switch-mode power supplies (SMPS), DC/DC converters, and motor control applications. --- ### 1. Key Technical Specifications The following table outlines the fundamental electrical characteristics of the device: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Drain-Source Voltage ($V_{DSS}$)** | 600V | Maximum voltage the device can withstand when off. | | **Continuous Drain Current ($I_D$)** | 2.0A | Maximum continuous current at $T_C = 25°C$. | | **Static Drain-Source On-Resistance ($R_{DS(on)}$)** | 4.5 $\Omega$ (Max) | Resistance when the gate is fully turned on. | | **Gate-Source Voltage ($V_{GSS}$)** | $\pm$ 30V | Maximum voltage range for the gate pin. | | **Total Gate Charge ($Q_g$)** | 9.0 nC (Typ) | Amount of charge required to fully switch the device. | | **Power Dissipation ($P_D$)** | 23W - 54W | Depends on the specific heat sinking and package. | --- ### 2. Physical Packaging and Naming The suffix **TF3-R** provides specific information about the physical form factor and shipping method: * **2N60L**: The base model number (600V, 2A MOSFET). The "L" usually signifies "Lead-free" or a specific low-gate-charge variant. * **TF3**: Refers to the **TO-220F** package. This is the "Full Pack" or isolated version of the standard TO-220. The tab is covered in plastic, meaning it does not require an additional insulating mica washer when mounted to a heatsink. * **-R**: Typically indicates **RoHS compliance** and/or **Tape & Reel/Tube** packaging. --- ### 3. Pin Configuration The device follows the standard power MOSFET pinout for the TO-220F package: 1. **Gate (G)**: Controls the switching of the MOSFET. 2. **Drain (D)**: The terminal where current enters (connected to the load). 3. **Source (S)**: The terminal where current exits (connected to ground). --- ### 4. Typical Applications Due to its high voltage rating and relatively low current, it is commonly found in: * **AC/DC Adapters**: Power bricks for laptops and electronics. * **LED Drivers**: Constant current supplies for lighting. * **Auxiliary Power Supplies**: Small standby power circuits in larger appliances. * **Electronic Ballasts**: Used in fluorescent lighting systems. --- ### 5. Equivalent/Substitute Parts If the 2N60L-TF3-R is unavailable, the following parts are often used as functional equivalents (always verify the package type): * **FDPF2N60** (Fairchild/ON Semi) * **STD2NK60** (STMicroelectronics) * **SSS2N60B** (Samsung)
