The **UTD413L-TN3-R** is an N-channel enhancement mode Power MOSFET manufactured by Unisonic Technologies (UTC). It is primarily designed for high-efficiency switching applications, power management, and DC-DC conversion. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the UTD413L-TN3-R: | Parameter | Symbol | Maximum Rating | | :--- | :--- | :--- | | **Drain-Source Voltage** | $V_{DSS}$ | 40 V | | **Gate-Source Voltage** | $V_{GSS}$ | ±20 V | | **Continuous Drain Current** | $I_D$ | 13 A | | **Static Drain-Source On-Resistance** | $R_{DS(ON)}$ | 42 mΩ (at $V_{GS}=10V$) | | **Pulsed Drain Current** | $I_{DM}$ | 52 A | | **Total Gate Charge** | $Q_g$ | 12 nC (typ) | | **Package Type** | TO-252 | D-PAK | --- ### 2. Physical and Packaging Features The part number suffix **"TN3-R"** provides specific information regarding the physical delivery and package: * **TN3:** Refers to the **TO-252** package (also known as D-PAK). This is a surface-mount package designed for heat dissipation. * **R:** Indicates **Tape and Reel** packaging for automated SMT (Surface Mount Technology) assembly. * **Lead-Free/Halogen-Free:** UTC products with these suffixes are typically compliant with RoHS standards. --- ### 3. Core Features and Benefits * **Low On-Resistance ($R_{DS(ON)}$):** Minimizes power loss during the "on" state, leading to higher efficiency. * **Fast Switching Speed:** Reduced gate charge allows the device to toggle between states quickly, which is critical for high-frequency PWM (Pulse Width Modulation) circuits. * **High Power Density:** The TO-252 package allows for a compact footprint while still handling significant current. --- ### 4. Typical Applications The UTD413L is commonly found in the following electronic circuits: 1. **Motor Drivers:** Controlling small to medium-sized DC motors. 2. **DC-DC Converters:** Buck or Boost converters in consumer electronics. 3. **Load Switches:** Turning power rails on or off within a system. 4. **LED Lighting Drivers:** Managing current for high-brightness LED arrays. --- ### 5. Identification Code (Pinout) For the TO-252 package, the standard pinout configuration is: 1. **Gate (G):** Controls the MOSFET state. 2. **Drain (D):** Connected to the thermal pad (backside). 3. **Source (S):** Reference point for the gate and output.
