The **3N60L-TM3-R** is a high-voltage N-Channel Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) commonly used in switching power supplies and DC-DC converters. Below is a detailed breakdown of its specifications and characteristics. ### 1. Key Technical Specifications The part number follows a specific nomenclature where "3" typically refers to the Current (Amps) and "60" refers to the Voltage (600V). | Parameter | Specification | | :--- | :--- | | **Transistor Type** | N-Channel MOSFET | | **Drain-Source Voltage ($V_{DSS}$)** | 600 V | | **Continuous Drain Current ($I_D$)** | 3.0 A | | **Pulsed Drain Current ($I_{DM}$)** | 12 A | | **Static Drain-Source On-Resistance ($R_{DS(ON)}$)** | 3.6 $\Omega$ (Max) @ $V_{GS}$ = 10V | | **Gate-Source Voltage ($V_{GS}$)** | $\pm$ 30 V | | **Package Type** | TO-251 (Short Lead) / TO-252 | | **Lead-Free Status** | Halogen Free / RoHS Compliant (L-Suffix) | --- ### 2. Physical Packaging (TM3-R) The suffix **TM3-R** describes the physical delivery and mounting format: * **TM3:** Refers to the **TO-251** package (often called I-PAK). This is a through-hole version of the D-PAK, featuring straight leads. * **R:** Generally indicates **Tape and Reel** or a specific orientation in packaging for automated assembly. --- ### 3. Core Features * **Low Gate Charge:** Designed to minimize switching losses, making it efficient at high frequencies. * **High Switching Speed:** Capable of rapid transitions between "on" and "off" states. * **Improved dv/dt Capability:** Robust against high-speed voltage transients, reducing the risk of device failure during switching. * **100% Avalanche Tested:** Ensures the device can handle unexpected energy spikes (inductive loads). --- ### 4. Typical Applications Because of its 600V rating and 3A current capacity, it is ideal for: 1. **Switch Mode Power Supplies (SMPS):** Used in the primary side of AC-DC adapters. 2. **LED Lighting:** Constant current drivers for high-voltage LED strings. 3. **Electronic Ballasts:** Fluorescent lighting circuits. 4. **DC-DC Converters:** High-efficiency power conversion in industrial equipment. --- ### 5. Pin Configuration (TO-251) Looking at the front of the component (label side): 1. **Gate (G):** Controls the "on/off" state. 2. **Drain (D):** Connected to the load (also connected to the metal tab). 3. **Source (S):** Connected to the ground or negative rail.
