Description and Introduction

N-CHANNEL 100V The **P40NF10L** from STMicroelectronics is a robust N-channel power MOSFET designed for high-efficiency switching applications. With a drain-source voltage (VDS) rating of 100V and a continuous drain current (ID) of 40A, this component is well-suited for power management in industrial, automotive, and consumer electronics.  

Featuring low on-resistance (RDS(on)) of just 0.04Ω, the P40NF10L minimizes conduction losses, enhancing energy efficiency in high-current circuits. Its fast switching capability ensures reduced power dissipation, making it ideal for applications such as DC-DC converters, motor drives, and load switching.  

The MOSFET is housed in a TO-220 package, providing excellent thermal performance and ease of mounting on heat sinks for improved heat dissipation. Additionally, its rugged design ensures reliability under demanding conditions, including high-temperature environments.  

Engineers favor the P40NF10L for its balance of performance, durability, and cost-effectiveness. Whether used in power supplies, inverters, or battery management systems, this MOSFET delivers consistent performance while maintaining operational stability. Its specifications make it a versatile choice for designers seeking a dependable power switching solution.

Application Scenarios & Design Considerations

N-CHANNEL 100V

Alternative Part Number

  • IRFZ44N --: Widely available N-channel logic-level MOSFET with comparable 55V/49A ratings, suitable drop-in for many 100V-class low-side switching designs.
  • FQP30N10 --: 100V N-channel MOSFET in TO-220 with similar current capability, good match for the P40NF10L voltage class and package.
  • IRLZ44N --: Logic-level N-channel MOSFET with low RDS(on) and 55V rating, usable in lower-voltage variants of the same application.
