The **M3H36FCD-R** is a high-performance, automotive-grade MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) manufactured by **Renesas Electronics**. It is specifically designed for high-current switching applications and is built using advanced trench technology. --- ### ## Technical Specifications Below are the primary electrical characteristics of the M3H36FCD-R: | Parameter | Symbol | Typical Value | Unit | | :--- | :--- | :--- | :--- | | **Drain-Source Voltage** | $V_{DSS}$ | 40 | V | | **Drain Current (DC)** | $I_D$ | 60 | A | | **On-State Resistance** | $R_{DS(on)}$ | 3.6 (max 4.5) | m$\Omega$ | | **Gate-Source Voltage** | $V_{GSS}$ | $\pm$20 | V | | **Channel Temperature** | $T_{ch}$ | 175 | °C | | **Package Type** | - | TO-252 (DPAK) | - | --- ### ## Key Features and Internal Construction #### 1. Low $R_{DS(on)}$ Technology The device is optimized for extremely low "on-resistance." This reduces power dissipation (heat generation) during conduction, allowing the component to handle high current loads efficiently. #### 2. Automotive Qualification The "R" suffix and the M3H series designation typically signify compliance with **AEC-Q101** standards. This means the part can withstand harsh environments, high vibration, and extreme temperature fluctuations common in vehicle electronics. #### 3. Logic Level Drive This MOSFET can be fully turned on using logic-level gate voltages (typically 4.5V to 10V), making it compatible with microcontrollers and dedicated gate driver ICs. #### 4. Package: TO-252 (DPAK) The DPAK is a surface-mount package designed for high-power applications. It features a large metal tab (the Drain) that serves as a heat sink to dissipate thermal energy into the PCB. --- ### ## Typical Applications Due to its high current capacity and reliability, the M3H36FCD-R is commonly found in: * **Power Steering Systems (EPS):** Controlling high-torque motors. * **DC-DC Converters:** Voltage regulation in automotive power grids. * **Load Switches:** Controlling high-current heaters, fans, or lighting. * **Motor Drives:** Used in H-bridge configurations for brushed or brushless DC motors. --- ### ## Pin Configuration | Pin Number | Name | Description | | :--- | :--- | :--- | | 1 | **Gate** | Controls the switching state (On/Off) | | 2/4 | **Drain** | Connected to the load (Tab is also Drain) | | 3 | **Source** | Connected to the ground or return path |
