R5009ANX Transistor

The R5009ANX is a single N-channel MOSFET (metal-oxide-semiconductor field-effect transistor) manufactured by Rohm Semiconductor. This product is intended for consumer electronics, low voltage applications, and power management.

Application Field

The R5009ANX is suitable for a variety of consumer electronics, including:

• Switching power supplies
• Three-phase motor drives
• Voltage regulators
• Solid-state relays
• Battery management
• Input/output buffers

The R5009ANX performs well in medium to high frequency switching applications, making it suitable for applications such as DC-DC converters and adapters, Class D amplifiers, motor control, and more.

Working Principle

MOSFET transistors work by using electric fields to control the flow of current in a circuit. A MOSFET is composed of a gate, a source and a drain. The electric field of the gate can be used to control the flow of electric current from the source to the drain. In the case of the R5009ANX, the N-channel MOSFET, a positive voltage applied to the gate allows current to flow freely between the source and drain, while a negative voltage applied to the gate shuts off the current.

The R5009ANX features a low threshold voltage, low input capacitance and minimal ‘on’ resistance. This makes it well-suited for low voltage applications where power management is critical. In addition, the R5009ANX offers excellent on-state and off-state control characteristics and has a high-speed switching capability.

Conclusion

The R5009ANX is an N-channel MOSFET suitable for a variety of applications, including switching power supplies, voltage regulators and battery management. It features low threshold voltage, low input capacitance, minimal on-resistance and excellent on-state and off-state control characteristics. It is ideal for low voltage applications, where power management and energy efficiency are critical.
