概要
Description
- Voltage Rating: 30V
- Current Rating: 61A (continuous)
- Low On-Resistance (RDS(on)): 3.7mΩ (max at 10V VGS)
- Fast Switching: Optimized for high-speed performance
- Logic-Level Gate Drive: Compatible with 4.5V drive
- Package: D2PAK (TO-263), surface-mountable
Ideal for DC-DC converters, motor control, and power management in automotive, industrial, and consumer electronics. Its low RDS(on) minimizes conduction losses, improving efficiency.

Pinout
1. Gate (G) – Controls the switching operation.
2. Drain (D) – Connects to the load (high-voltage side).
3. Source (S) – Connects to ground (low-voltage side).
Key Features:
- 30V Drain-Source Voltage (VDS)
- 195A Continuous Drain Current (ID)
- Ultra-low On-Resistance (RDS(on) = 1.7mΩ @ 10V VGS)
- Logic-Level Gate Drive (4V VGS)
Commonly used in power switching, motor control, and DC-DC converters for high-efficiency applications.
Application
1. Power Management – DC-DC converters, voltage regulators.
2. Motor Control – Brushed DC and stepper motor drivers.
3. Load Switching – Power distribution in automotive, industrial, and consumer electronics.
4. Battery Protection – Discharge control in portable devices.
5. LED Drivers – Efficient current control for lighting systems.
Its low on-resistance (1.8mΩ) and high current handling (195A pulsed) make it ideal for high-efficiency, high-power applications.
