The IRF7805ZTRPBF is an N-channel Power MOSFET designed and manufactured by Infineon Technologies. Here's how it can be described in terms of its configuration, function, and application fields:


  • Type: N-channel MOSFET
  • Package: 8-SO (Small Outline, 8 leads, e.g., SOIC, SOJ, SO, SOIC Narrow)
  • Pinout: Typically, N-channel MOSFETs have three pins: Gate, Drain, and Source. The specific pinout can be obtained from the datasheet.

Function: The primary function of the IRF7805ZTRPBF N-channel MOSFET is to act as a switch or amplifier in electronic circuits. MOSFETs, when used as a switch, can carry and block significant levels of current, making them suitable for various power management applications.

As a switch, it can control the flow of current between the drain and source terminals. When a suitable voltage is applied to the gate terminal, it allows current to flow between the drain and source (i.e., the MOSFET is "on"). When the gate voltage is removed or reduced, the current flow is interrupted (i.e., the MOSFET is "off"). This switching function is vital in applications such as power supplies, motor control, LED lighting, and many other types of electronic control circuits.

Moreover, MOSFETs like the IRF7805ZTRPBF can be used in amplifier circuits where they can provide gain and control over signals, but their most common role in modern electronics is as a high-efficiency switch.

Application Field:

  • Power Supplies: In switch-mode power supplies, MOSFETs like the IRF7805ZTRPBF are used to efficiently regulate the flow of power from the input to the output, controlling the voltage and current levels with high precision.
