Description

The IRF7240PBF is a P-channel power MOSFET from Infineon Technologies, designed for high-efficiency switching applications. Key features include:
- Voltage Rating: -40V (drain-to-source)
- Current Rating: -12A (continuous drain current)
- Low On-Resistance: 60mΩ (max at VGS = -10V)
- Fast Switching: Optimized for high-speed performance
- Package: TO-220AB (through-hole, easy to mount)
Commonly used in DC-DC converters, motor control, and power management circuits, it offers reliable performance with low gate charge for reduced switching losses. The P-channel configuration simplifies high-side switching by allowing gate drive relative to ground.
Applications:
- Battery protection
- Load switching
- Power supplies
Its PBF suffix indicates lead-free (RoHS-compliant) construction. Always refer to the datasheet for detailed specs and thermal considerations.
