The **2N80L-TM3-R** is a specific type of N-Channel Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) commonly used in switching applications. It is designed to handle high voltages while maintaining low resistance. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the component's specifications: | Part Segment | Meaning | | :--- | :--- | | **2N80** | **2 Amps** (Drain Current) and **800 Volts** (Drain-Source Voltage). | | **L** | **Lead-free** / RoHS compliant. | | **TM3** | **Package Type** (Typically refers to TO-251 or "IPAK"). | | **R** | **Tape & Reel** (Packing method). | --- ### 2. Key Technical Specifications Below are the typical electrical characteristics for this MOSFET: | Parameter | Symbol | Value | | :--- | :--- | :--- | | Drain-Source Voltage | $V_{DSS}$ | 800V | | Continuous Drain Current | $I_D$ | 2.0A | | Pulsed Drain Current | $I_{DM}$ | 8.0A | | Gate-Source Voltage | $V_{GSS}$ | ±30V | | On-State Resistance | $R_{DS(ON)}$ | ~5.0Ω to 6.3Ω (Max) | | Total Gate Charge | $Q_g$ | 12nC (Approx) | --- ### 3. Physical Features & Structure The 2N80L-TM3-R is built using **Advanced Planar Stripe Technology**. This provides several advantages: * **Low On-Resistance:** Reduces power loss during the "ON" state. * **Fast Switching:** Allows the device to turn on and off rapidly, which is essential for modern power supplies. * **High Avalanche Energy:** The device is rugged and can survive short-duration high-voltage spikes (Avalanche ruggedness). --- ### 4. Common Applications Due to its high voltage rating (800V), this part is rarely used in battery-operated gadgets and is instead found in: 1. **Switching Mode Power Supplies (SMPS):** Used as the primary switch in AC-to-DC converters. 2. **LED Drivers:** Controlling power flow to high-voltage LED arrays. 3. **Electronic Ballasts:** Used in lighting circuits. 4. **DC-DC Converters:** High-efficiency power conversion in industrial equipment. --- ### 5. Schematic Connection In a typical circuit, the three pins are used as follows: ```text Pin 1: Gate (G) -> Control signal (Trigger) Pin 2: Drain (D) -> Connected to the Load (High voltage side) Pin 3: Source (S) -> Connected to Ground (Return path) ```
