## Overview of the 2N80L-TN3-R The **2N80L-TN3-R** is an N-Channel enhancement mode Power MOSFET designed for high-voltage, high-speed switching applications. It is commonly used in power supplies, motor drivers, and DC-to-DC converters. ### 1. Key Technical Specifications | Parameter | Symbol | Typical Value | |:---|:---:|:---| | **Drain-Source Voltage** | $V_{DSS}$ | 800V | | **Continuous Drain Current** | $I_D$ | 2.0A | | **Drain-Source On-Resistance** | $R_{DS(ON)}$ | 6.3 $\Omega$ (Max) | | **Gate-Source Voltage** | $V_{GS}$ | $\pm$ 30V | | **Total Gate Charge** | $Q_g$ | 12 nC | | **Package Type** | - | TO-252 (D-PAK) | --- ### 2. Physical and Pin Configuration The **TN3** suffix in the part number indicates the package type, which is **TO-252** (also known as D-PAK). This is a surface-mount package designed for efficient heat dissipation. 1. **Gate (G):** Controls the biasing of the MOSFET. 2. **Drain (D):** Connected to the high-voltage load (usually the center tab in TO-252). 3. **Source (S):** Connected to the ground or negative side of the circuit. --- ### 3. Features and Benefits * **High Voltage Capability:** With an 800V rating, it is suitable for AC-to-DC rectification stages and industrial power systems. * **Low Gate Charge:** Allows for faster switching speeds and reduced drive power requirements. * **Robustness:** High ruggedness against $dv/dt$ (voltage spikes), improving reliability in inductive load switching. * **RoHS Compliant:** The "R" in the suffix usually denotes compliance with environmental standards and tape-and-reel packaging. --- ### 4. Typical Applications * **Switching Mode Power Supplies (SMPS):** Used in the primary side of the power supply. * **LED Lighting:** Constant current drivers for high-voltage LED strings. * **Electronic Ballasts:** Used in lighting control circuits. * **Adapters:** Power adapters for laptops and industrial electronics. ### 5. Identification Code Breakdown `2N80` typically refers to the electrical characteristics (**2** Amps, **80**0 Volts), while `L` often denotes a "Lead-free" or specific process variant by the manufacturer (likely UTC - Unisonic Technologies). ---
