IRFP250 Power MOSFET Datasheet

Introduction

The IRFP250 is a high-performance N-channel power MOSFET widely used in a variety of high-power, high-frequency applications. As a third-generation power MOSFET, it is manufactured with advanced processing techniques to deliver a strong combination of low on-resistance, fast switching speeds, and exceptional ruggedness. This makes it an ideal choice for switching regulators, motor control circuits, and power converters where efficiency and reliability are paramount. It can handle a continuous drain current of up to 33A and a drain-source voltage of 200V, providing a robust solution for a wide range of demanding tasks. The TO-247 package provides excellent thermal dissipation, ensuring the device can operate reliably at higher power levels.

The IRFP250’s low on-resistance (RDS(on)​), typically 0.085Ω, significantly reduces power loss during the conduction state, minimizing heat generation and improving overall system efficiency. Its fast switching speed, with turn-on and turn-off times in the nanosecond range, makes it highly effective in high-frequency switching applications, such as DC-DC converters and inverters. The dynamic dV/dt rating and repetitive avalanche rating are crucial features that ensure the MOSFET’s durability and ability to withstand the electrical stresses of inductive loads, providing a higher level of reliability.

Equivalent MOSFETs of IRFP250

While an exact one-for-one replacement is rarely possible, several MOSFETs are considered functional equivalents or suitable alternatives for the IRFP250, provided their specifications match the specific needs of your circuit. When selecting a substitute, prioritize matching the drain-source voltage (VDS​), continuous drain current (ID​), and on-resistance (RDS(on)​).

Here’s a list of common equivalent MOSFETs for the IRFP250:

• IRFP250N: The modern version from Infineon. It has very similar, often slightly better, specs but is known to be less robust to “abuse” compared to the original.
• IRFP260: A higher-power counterpart with the same 200V rating but a significantly higher drain current of 50A and a lower on-resistance. This can be a reliable upgrade.
• STP20N20: An N-channel MOSFET from STMicroelectronics with comparable ratings, making it a good cross-reference option.
• IRFP240: A related MOSFET with the same 200V rating but a slightly lower drain current and higher on-resistance. It’s a viable alternative for applications with less demanding current requirements.
• FQA29N20: Manufactured by Fairchild, this MOSFET is also a 200V, 29A component that can be used as a substitute in many applications.
