The **3N60G-TM3-R** is a specific type of N-Channel Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) commonly used in switching power supplies and high-voltage applications. Here is a detailed breakdown of its specifications and characteristics: --- ### 1. General Specifications The part number follows a standard nomenclature where "3" typically refers to the current rating and "60" refers to the voltage rating. | Parameter | Specification | Description | | :--- | :--- | :--- | | **Type** | N-Channel MOSFET | Logic-controlled high-voltage switch | | **Drain-Source Voltage ($V_{DSS}$)** | 600V | Maximum voltage the device can handle | | **Continuous Drain Current ($I_D$)** | 3.0A | Max current flow at 25°C | | **Gate-Source Voltage ($V_{GS}$)** | ±30V | Max voltage to trigger the gate | | **On-Resistance ($R_{DS(on)}$)** | ~3.6Ω | Resistance when the device is fully ON | | **Package Type** | TO-251 (TM3) | Through-hole "IPAK" style package | --- ### 2. Key Features * **Low Gate Charge:** Requires minimal energy to switch between ON and OFF states, enabling high-frequency operation. * **High Switching Speed:** Reduces power loss during the transition phases. * **100% Avalanche Tested:** Ensures reliability against voltage spikes that exceed the rated breakdown voltage. * **RoHS Compliant:** The "G" in the suffix usually denotes "Halogen-Free" or "Green" materials. --- ### 3. Pin Configuration The TO-251 (TM3) package typically follows the standard MOSFET pinout: 1. **Gate (G):** Controls the flow of current between Drain and Source. 2. **Drain (D):** Connected to the high-voltage load. 3. **Source (S):** Connected to the ground or common return. --- ### 4. Typical Applications Because of its high voltage rating (600V) and moderate current capacity (3A), it is found in: * **AC/DC Adapters:** Power bricks for laptops and electronics. * **LED Drivers:** Constant current circuits for lighting. * **SMPS:** Switching Mode Power Supplies. * **DC-DC Converters:** High-voltage industrial power regulation. --- ### 5. Part Number Suffix Breakdown * **3N60:** 3 Amps, 600 Volts. * **G:** Halogen-free/Green material. * **TM3:** Package code for TO-251 (Long Lead IPAK). * **R:** Usually denotes Tape and Reel or specific Tube packaging.
