  • Low forward voltage drop improves efficiency
  • 40 V reverse voltage handles typical rail voltages
  • 3 A forward current supports moderate loads
  • nSMC-2 package enables compact surface-mount assembly

YINGHUA NSQ03A04 Schottky Diode

The YINGHUA NSQ03A04 is a Schottky diode rated for 40V and 3A in an nSMC-2 surface-mount package. It serves engineers and hobbyists building rectification, freewheeling or polarity-protection circuits where low forward voltage drop and fast switching are required. Supplied new, it suits prototype runs and volume assembly alike.

Designers needing higher voltage or current

This device suits designs that stay within the 40V and 3A limits. Buyers who need more voltage headroom or greater current capacity should look at other parts. It is also not intended for applications that demand a different package outline or alternative semiconductor technology.

Questions about this item

How can I verify the NSQ03A04 is functioning correctly after soldering it to the PCB?

Measure the forward voltage drop across the diode with a multimeter; a healthy Schottky typically shows a low reading consistent with its 40V 3A rating.

What is included in the package and what extra items are needed for installation?

The package contains the NSQ03A04 diodes in nSMC-2 format; you will need solder, flux and standard SMT assembly tools to mount them.
