IRF540N – IRF540 N-Channel MOSFET Transistor (TO-220)

Description

• MOSFET Type: N-channel MOSFETs are typically used to control the flow of current between the source and drain terminals when a voltage is applied to the gate terminal. The IRF540N is an N-channel MOSFET, which means it conducts current when a positive voltage is applied to its gate relative to its source terminal.
• Voltage Rating: The IRF540N is known for its relatively high voltage rating. It can handle a maximum drain-source voltage of up to 100 volts, which makes it suitable for applications requiring high voltage switching.
• Current Rating: It has a reasonably high continuous drain current rating of around 33 amperes (33A). This indicates its ability to handle substantial current loads.
• Package Type: The IRF540N is typically available in a TO-220 package. The TO-220 package is a common through-hole package with a metal tab for efficient heat dissipation. This allows for easy mounting on a heatsink, making it suitable for power applications.
• Applications: N-channel MOSFETs like the IRF540N are used in various applications, including motor control, power amplification, voltage regulation, and switching circuits.
• Gate Threshold Voltage: The gate threshold voltage (Vgs(th)) is the voltage required to turn the MOSFET on. For the IRF540N, this value typically falls within the range of 2 to 4 volts.
• On-Resistance: The on-resistance (Rds(on)) of the IRF540N can vary, but it is generally relatively low for its current and voltage ratings. A lower Rds(on) value means less power dissipation when the MOSFET is on.
• Heat Dissipation: Due to the higher current and voltage ratings of the IRF540N, efficient heat dissipation is important, and it’s common to use a heatsink when using this MOSFET in high-power applications.
