The **FP3003** is a high-performance, high-voltage N-Channel Enhancement Mode Trench MOSFET. It is primarily used in power management applications where efficiency and high-speed switching are critical. --- ### ## Technical Specifications Below are the primary electronic characteristics of the FP3003: | Parameter | Symbol | Typical Value | Unit | | :--- | :--- | :--- | :--- | | **Drain-Source Voltage** | $V_{DSS}$ | 30 | V | | **Gate-Source Voltage** | $V_{GSS}$ | $\pm$ 20 | V | | **Continuous Drain Current** | $I_D$ | 60 - 80 | A | | **Static Drain-Source On-Resistance** | $R_{DS(on)}$ | 4.5 - 6.0 | m$\Omega$ | | **Total Gate Charge** | $Q_g$ | 15 - 20 | nC | | **Operating Temperature** | $T_j$ | -55 to +150 | $^\circ$C | --- ### ### Core Electronic Features 1. **Trench Technology:** The FP3003 utilizes "Trench" construction, which increases the density of the cells within the silicon. This significantly reduces the **$R_{DS(on)}$** (On-Resistance), leading to lower power dissipation and higher efficiency. 2. **Low Gate Charge ($Q_g$):** It features a low total gate charge, which allows for faster switching speeds. This makes it ideal for high-frequency DC-DC converters where switching losses must be minimized. 3. **High Current Capability:** Despite its small footprint (often found in **TO-252** or **PDFN5x6** packages), it can handle significant continuous currents, making it robust for motor control. 4. **Avalanche Ruggedness:** The device is designed to handle high energy in the "avalanche" mode, providing a safety margin against voltage spikes from inductive loads. --- ### ### Common Applications * **DC-DC Converters:** Used in Buck or Boost converters for voltage regulation. * **Motor Drivers:** Ideal for H-bridge configurations in small motor control systems. * **Load Switches:** Used in battery management systems (BMS) to connect or disconnect the load safely. * **Synchronous Rectification:** Used in the secondary side of power supplies to improve efficiency over traditional diodes. --- ### ### Pin Configuration (Typical TO-252) ```text _______ | [D] | <-- Drain (Tab/Pin 2) | FP3003| |_______| | | | G D S (Gate, Drain, Source) 1 2 3 ```
