About the Product

High-Efficiency 55V MOSFET for Motor Control & Power Switching

Engineered for demanding automotive and industrial applications, the AUIRF4905S P-Channel MOSFET delivers 55V/42A power handling with an ultra-low 20mΩ RDS(on) for maximum efficiency. This surface-mount D2PAK transistor features advanced planar technology, making it the ideal solution for motor drives, power tools, and EV battery management systems.

 

Ultra-Low 20mΩ RDS(on) P-Channel MOSFET - 175°C Operation Rated

✔ Automotive-Grade Reliability – Rated for 175°C operation with repetitive avalanche capability
✔ High-Current Handling – 42A continuous current (70A pulsed) for robust power switching
✔ Fast Switching – 120nC gate charge enables high-frequency operation
✔ Wide Compatibility – ±20V VGS range for flexible drive circuits
✔ Proven Durability – 170W power dissipation in compact D2PAK package

 

Key Applications:

  • EV motor controllers and power tool speed regulation
  • DC-AC inverters and power supply switching
  • Industrial automation equipment
  • Medical device power management
  • Battery protection circuits
