Product Overview

IRF540NPBF is a high-performance N-channel power Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), specifically designed for high-voltage and high-current switching scenarios. It is one of the core components in the field of power electronics. IRF540NPBF features core advantages including 100V high drain-source voltage (Vds), 33A continuous drain current (Id), and 0.04Ω low on-resistance (Rds(on)), which can effectively reduce circuit loss and improve system energy efficiency. It is widely suitable for power control needs in industrial, consumer electronics, and automotive electronics fields. With stable electrical performance and eco-compliant design, IRF540NPBF is a classic model preferred by engineers in power switch design.

Key Features

• High Voltage Tolerance: The maximum drain-source voltage (Vds) of IRF540NPBF reaches 100V, which can stably cope with high-voltage applications within 100V, adapting to high-voltage circuits such as switching power supplies and inverters, and avoiding device damage caused by voltage fluctuations.
• Low Conduction Loss Advantage: Under the condition of Vgs=10V, the typical on-resistance (Rds(on)) of IRF540NPBF is only 0.04Ω, with extremely low conduction loss. According to the formula P=I²R, the loss is only 36W at 30A current, significantly improving circuit energy efficiency.
• High Current-Carrying Capacity: At 25℃, the continuous drain current (Id) of IRF540NPBF can reach 33A, and it still maintains 21A current output at 100℃, which can meet the needs of high-current loads such as motor drives and high-power lighting.
• Stable Operation in Wide Temperature Range: The operating temperature range of IRF540NPBF covers -55℃~175℃. It can adapt to outdoor equipment in cold areas at low temperatures and tolerate the heating environment of industrial equipment at high temperatures, and can operate stably without additional temperature control modules.
• Global Eco-Compliance: IRF540NPBF fully complies with RoHS environmental standards, free of lead, mercury, and other harmful substances. It meets environmental regulations in the EU, North America, and other regions, and is suitable for the production of electronic equipment with strict environmental requirements.

Typical Applications

• Switching Power Supply Field: In AC-DC and DC-DC switching power supplies, IRF540NPBF serves as the core switching device. With 100V high Vds and 0.04Ω low Rds(on), it realizes efficient voltage conversion, reduces switching and conduction losses, adapts to medium and high-power equipment such as server power supplies and industrial power supplies, and improves power supply energy efficiency to over 90%.
• Motor Drive Systems: For the drive circuits of DC motors and stepper motors, the 33A high Id of IRF540NPBF can provide sufficient drive current, and the wide-temperature characteristic adapts to the temperature change during motor operation, ensuring the stable and reliable operation of automotive wiper motors and industrial conveyor motors during startup, stop, and speed regulation.
• LED Lighting Drive: In high-power LED street lights and industrial lighting, IRF540NPBF can be used as a current control switch. The low on-resistance reduces current transmission loss, avoiding device heating affecting LED lifespan. The 100V Vds adapts to the voltage demand of multi-series LEDs, ensuring long-term stable operation of lighting equipment.
• Solar Inverters: Solar inverters need to convert DC power to AC power. The high-voltage and high-current characteristics of IRF540NPBF adapt to the power switching link of inverters, and the temperature resistance copes with outdoor temperature fluctuations, ensuring the inverter works continuously in the environment of -30℃~60℃ and improving the efficiency of the solar power generation system.
• Automotive Electronic Auxiliary Systems: In automotive auxiliary systems such as window lifting and seat adjustment, IRF540NPBF meets the temperature resistance requirements of automotive electronics (-55℃ low-temperature startup), 33A current drives small motors, and the eco-compliant design meets automotive industry standards, reducing the failure risk of auxiliary systems.

Why Choose IRF540NPBF ?

• Wide Parameter Coverage, Strong Adaptability: The 100V Vds, 33A Id, and 0.04Ω Rds(on) of IRF540NPBF cover most medium and high-power applications. Compared with similar MOSFETs, there is no need to change models to adapt to multiple scenarios such as switching power supplies and motor drives, reducing selection costs.
• High Environmental Tolerance, Strong Reliability: The wide temperature range of -55℃~175℃ + voltage fluctuation resistance design enables IRF540NPBF to cope with harsh environments such as industrial high temperatures and outdoor low temperatures. The device failure rate is less than 0.1%, improving the reliability of end products.
• Package Compatibility, Convenient Design: IRF540NPBF adopts the industry-standard TO-220AB package, which can be directly compatible with most PCB designs without special package adaptation. The ±20V Vgs is compatible with common driver chips, reducing the complexity of driver circuit design and shortening the R&D cycle.
• Complete Quality Certifications, High Compliance: IRF540NPBF has passed international certifications such as UL and CE, complies with RoHS environmental standards, and adopts ISO9001 quality control in the production process. The parameter consistency error of each batch is ≤5%, avoiding product recall risks caused by device quality.
• Mature Supply Chain, Stable Supply: As a classic model, IRF540NPBF has a mature global supply chain with a short delivery cycle (7-10 days for regular orders). It supports multiple packaging types such as tube packaging and bag packaging, meeting the different needs of small-batch trial production and large-batch production, and reducing procurement risks.
