Frequently Asked Questions (FAQ)

Q1: Can it be used for 3.3V system control?
A: Yes. The NDS0605 is an N-channel MOSFET with a low gate voltage. It achieves low on-resistance (typically approximately 60mΩ) at VGS = 2.5V, making it fully compatible with 3.3V or 2.5V digital control signals. This makes it ideal for on/off control, power supply/load switching, or level shifting in low-voltage systems such as FPGAs, MCUs, and SoCs.

Q2: Can two channels be used in parallel?
A: Parallel connection is structurally possible, but in practice, several key points should be noted: First , the lead length and current path should be kept consistent between devices to minimize current unevenness caused by distributed resistance. Second, power loss will be concentrated in the device that turns on earlier, which may cause local overheating. Therefore, it is recommended to use devices from the same batch and to properly arrange copper foil heat dissipation and thermal balance in the PCB design. For high current applications, independent drive circuits can also be considered to improve system stability and lifespan.
