The **2N60LL-TND-R** is a specific part number for an N-Channel Power MOSFET, typically manufactured by companies like UTC (Unisonic Technologies). It is designed for high-voltage, high-speed switching applications. --- ## 1. Technical Specifications The core parameters of the 2N60 series usually revolve around its power handling and resistance capabilities: | Parameter | Typical Value | Description | |:---|:---|:---| | **Drain-Source Voltage ($V_{DSS}$)** | 600V | Maximum voltage across drain and source | | **Drain Current ($I_D$)** | 2.0A | Continuous current handling | | **Gate-Source Voltage ($V_{GSS}$)** | ±30V | Maximum gate control voltage | | **$R_{DS(ON)}$** | ~3.8Ω to 4.4Ω | Resistance when the transistor is fully "on" | | **Total Gate Charge ($Q_g$)** | 9.0nC | Amount of charge required to switch the gate | --- ## 2. Key Features * **Low Gate Charge:** Allows for fast switching speeds and reduced drive power requirements. * **Avalanche Ruggedness:** Designed to handle momentary voltage spikes without immediate failure. * **Low $C_{rss}$:** Low reverse transfer capacitance improves efficiency in high-frequency circuits. * **Package Type:** The "TND" suffix often refers to a specific package variant, likely **TO-252 (DPAK)** or **TO-251 (IPAK)**, suitable for surface-mount or compact through-hole designs. --- ## 3. Part Number Breakdown While manufacturer codes vary slightly, the nomenclature usually follows this logic: * **2N60:** 2 Amps / 600 Volts (Base series). * **LL:** Low Leakage or specific "Low" characteristic version. * **TND:** Package/Lead style indicator (Often TO-252/DPAK). * **R:** Tape and Reel packaging (for automated pick-and-place machines). --- ## 4. Common Applications Due to its high voltage rating and moderate current, this MOSFET is frequently used in: 1. **Switch Mode Power Supplies (SMPS):** Acting as the main switching element. 2. **LED Drivers:** Controlling power to high-voltage LED strings. 3. **DC-DC Converters:** Stepping down high DC voltages. 4. **Electronic Ballasts:** Used in lighting control circuits. --- ## 5. Typical Schematic Representation In a circuit, the pinout for the DPAK (TO-252) version is usually: ```text Pin 1: Gate (Control) Pin 2: Drain (Connected to Case) Pin 3: Source (Ground/Return) ```
