MOSFET N‑channel Infineon IRF540NPBF, TO-220 package, 130 W power rating

Infineon IRF540NPBF is an N‑channel MOSFET housed in a TO‑220 through‑hole package, engineered for switching and amplification in power electronics applications. With a rated power dissipation of 130 W, the device offers the conduction and thermal management characteristics common to TO‑220 components, making it suitable for circuits where reliable handling of moderate power and straightforward mounting are required.

Advantages

The MOSFET provides low on‑resistance and stable switching performance appropriate for general‑purpose power switching and linear amplification. The TO‑220 package facilitates effective heat sinking and easy PCB or chassis mounting. Infineon manufacturing and device design ensure consistent electrical characteristics and robustness under typical operating conditions for power supplies and motor control circuits.

Suitable for

• Motor drivers and motor control circuits
• DC–DC converters and voltage regulators
• Linear and switching power supplies
• General‑purpose switching and load drivers
• Prototyping and repair of through‑hole power electronics

Key specifications

• Transistor type: N‑channel MOSFET
• Package: TO‑220 through‑hole
• Power dissipation: 130 W (package dependent, with adequate cooling)
• Intended use: switching and amplification in power electronic circuits
• Mounting: vertical or with heatsink for thermal management

How to use

Install the MOSFET on a PCB or secure it to a heatsink using the TO‑220 mounting tab to ensure proper thermal transfer. Observe correct gate, drain and source connections and follow recommended gate‑drive levels suitable for the circuit topology. Provide appropriate gate resistors, snubbers or flyback diodes when switching inductive loads. Ensure thermal design (heatsink, airflow, or PCB copper) matches expected dissipation to keep junction temperature within safe limits.

Usage recommendations

For reliable operation, use the device within its specified voltage, current and thermal limits, apply proper gate‑drive voltages, and include protection components (such as diodes, resistors and transient suppression) when working with inductive or high‑energy circuits. When mounting, attach a suitable heatsink and consider thermal compound to improve heat transfer.
