- **Drain-Source Voltage (VDS):** 30V  
- **Continuous Drain Current (ID):** 62A (at 25°C)  
- **Pulsed Drain Current (IDM):** 250A  
- **Gate-Source Voltage (VGS):** ±20V  
- **Power Dissipation (PD):** 79W (at 25°C)  
- **On-Resistance (RDS(on)):** 8.0mΩ (max) at VGS = 10V  
- **Threshold Voltage (VGS(th)):** 1.0V to 2.0V  
- **Total Gate Charge (Qg):** 44nC (typical)  
- **Operating Junction Temperature (TJ):** -55°C to +175°C  
- **Package:** TO-252 (DPAK)  

### **Description:**  
The IRLR7821PBF is a high-performance N-channel MOSFET designed for low-voltage, high-current switching applications. It features low on-resistance and fast switching speeds, making it suitable for power management in DC-DC converters, motor control, and other high-efficiency applications.  

### **Features:**  
- Low gate charge for fast switching  
- Low RDS(on) for reduced conduction losses  
- High current handling capability  
- Avalanche energy specified  
- Lead-free and RoHS compliant  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

30V Single N-Channel HEXFET Power MOSFET in a D-Pak package

Alternative Part Number

  • CSD18540Q5B --: N-channel NexFET MOSFET in 5x6 SON package with comparable 60V rating and low RDS(on), suitable replacement for synchronous buck and power switching applications.
  • FDP8878 --: 60V N-channel PowerTrench MOSFET in TO-220 with similar current capability and low on-resistance, a common drop-in class alternative for the IRLR7821.
  • BSC0902NSI --: OptiMOS N-channel MOSFET in SuperSO8 with comparable voltage class and low RDS(on), well suited for high-efficiency power conversion designs.
