Product Overview

The IRFP9240PBF is a high-performance P-Channel Power MOSFET launched by Infineon Technologies (formerly International Rectifier), specifically designed for high-voltage, high-current power electronics applications. With core advantages of -200V high-voltage tolerance, -12A high-current output, and 1.5Ω low on-resistance, this product serves as a key component in switching power supplies, motor drives, industrial controls, and other fields. The IRFP9240PBF effectively reduces circuit conduction losses, improves system efficiency, and features a wide operating temperature range of -55℃~150℃, making it suitable for various harsh working conditions. It is a preferred IRFP9240PBF power solution for engineers in power conversion and control design.

Key Features

• High Voltage Rating for Safety & Stability：The IRFP9240PBF has a maximum drain-source voltage (Vds) of -200V, which can stably handle high-voltage applications (such as 200V input switching power supplies), avoid voltage breakdown risks, and ensure long-term safe operation of the system.
• Low On-Resistance for High Efficiency：With a typical on-resistance (Rds(on)) of only 1.5Ω (@Vgs=-10V, Id=-6A), the IRFP9240PBF significantly reduces conduction losses during operation, helping to increase the overall circuit efficiency by 3%-5%.
• High Current Capacity for High Power：At Tc=25℃, the continuous drain current (Id) of the IRFP9240PBF can reach -12A, and it still maintains -7.5A output at high temperature (Tc=100℃), meeting high-current requirements for motor drives and power amplification.
• Wide Temperature Adaptation for Environmental Compatibility：The operating junction temperature (Tj) ranges from -55℃ to 150℃. Even in extremely cold (outdoor equipment in northern regions) or high-temperature (inside industrial equipment) environments, the IRFP9240PBF remains stable without additional temperature compensation circuits.
• Environmental Compliance for Global Access：The IRFP9240PBF fully complies with RoHS 2.0 and REACH standards, free of lead, mercury, and other hazardous substances. It helps enterprises easily pass international certifications such as CE and FCC, with no environmental compliance risks.

Technical Specifications

Typical Applications

• Switching Power Supplies (SMPS)：In AC-DC and DC-DC switching power supplies, the IRFP9240PBF acts as the main switching transistor to achieve efficient power conversion, thanks to its -200V high-voltage tolerance and low on-resistance. It reduces power loss of the power supply and is suitable for medium and high-power designs such as industrial power supplies and server power supplies, which is the core application of IRFP9240PBF in the power supply field.
• Motor Drives：For drive circuits of DC motors and stepper motors, the IRFP9240PBF provides a continuous high-current output of -12A to stably drive motor operation. Its wide temperature range ensures reliable operation of motors in high or low-temperature environments such as industrial machine tools and automotive auxiliary motors, avoiding drive failures caused by temperature fluctuations.
• Audio Power Amplification：In professional audio amplifiers and sound systems, the IRFP9240PBF serves as the core component of the power amplification stage. Its low on-resistance reduces signal distortion, and its high current capacity ensures the dynamic range of audio output, providing users with clear and stable sound quality—this is a typical application of IRFP9240PBF in the consumer electronics field.
• Solar Inverters：Solar inverters need to convert low-voltage DC power from photovoltaic panels to high-voltage AC power. The -200V high-voltage rating of the IRFP9240PBF adapts to conversion requirements, and its efficient conduction performance reduces inverter power consumption, improving the overall energy utilization rate of the solar power generation system.
• Industrial Control Equipment：In equipment such as PLCs (Programmable Logic Controllers) and frequency converters, the IRFP9240PBF is used in power output and control modules. Its wide temperature range of -55℃~150℃ copes with complex temperature environments in industrial sites, ensuring long-term stable operation of control equipment and reducing downtime and maintenance frequency.

Why Choose IRFP9240PBF?

• Comprehensive Parameters for Multi-Scenario Adaptation：The parameter combination of -200V high voltage, -12A high current, and 1.5Ω low resistance of the IRFP9240PBF covers high-voltage, high-current, and high-efficiency requirements. It can be directly adapted to multiple scenarios such as switching power supplies and motor drives, reducing the difficulty of engineer selection and design.
• Low Loss & High Efficiency for Cost Reduction：Compared with similar MOSFETs, the low on-resistance of the IRFP9240PBF reduces conduction losses by more than 30%, minimizing component heat generation. It not only improves system efficiency but also reduces heat dissipation design costs and extends equipment service life.
• Wide Temperature Reliability for Strong Environmental Tolerance：The operating junction temperature range of -55℃~150℃ allows the IRFP9240PBF to work in extremely cold and high-temperature environments without additional protection, making it particularly suitable for harsh scenarios such as industrial control and automotive electronics, and reducing system complexity.
