Key Technical Specifications The following table outlines the core electronic parameters for the M3H16FAG-R: | Parameter | Symbol | Typical Value | | :--- | :--- | :--- | | **Drain-to-Source Voltage** | $V_{DSS}$ | 40 V | | **Continuous Drain Current** | $I_D$ | 160 A | | **Static Drain-Source On-Resistance** | $R_{DS(on)}$ | 1.1 mΩ (typ) @ 10V | | **Gate-to-Source Voltage** | $V_{GSS}$ | ±20 V | | **Operating Junction Temperature** | $T_j$ | -55 to +175 °C | | **Package Type** | - | TO-263 (D2PAK-7pin) | --- ### 2. Physical and Structural Characteristics * **AEC-Q101 Qualified:** This part is specifically designed and tested to meet automotive reliability standards, ensuring it can withstand high vibration and extreme temperature cycles. * **Low $R_{DS(on)}$:** The internal resistance during conduction is extremely low (approx. 1.1 milliohms), which minimizes power loss (heat generation) and increases overall system efficiency. * **Package Design:** The 7-pin TO-263 package provides superior heat dissipation and lower lead inductance compared to standard 3-pin TO-220 or TO-263 variants, allowing for higher current handling. --- ### 3. Application Use Cases Due to its high current capacity and low resistance, the M3H16FAG-R is commonly integrated into the following circuits: 1. **Automotive Power Steering (EPS):** Handling the high-torque motor control requirements. 2. **DC-DC Converters:** Acting as a high-speed switch in buck or boost regulators for electric vehicles. 3. **Battery Management Systems (BMS):** Used in safety disconnects or cell balancing where high current flow is expected. 4. **Motor Drives:** Efficiently driving BLDC (Brushless DC) motors in industrial tools. --- ### 4. Gate Drive Considerations To utilize this MOSFET effectively, the gate drive circuit should be designed with the following in mind: * **Logic Level:** While it can turn on at lower voltages, optimal performance (lowest resistance) is achieved with a gate voltage ($V_{GS}$) of 10V. * **Gate Charge ($Q_g$):** Because it is a large power MOSFET, it has a high gate capacitance. A robust gate driver is necessary to charge/discharge the gate quickly for high-frequency switching.
