Juxing 1SMA4730A 1W 3.9V Zener Diode Suitable for Surface Mounted Design with SMA Package

Product Description

Product Description Zener diode is a specialized type of diode that is designed to work in the reverse breakdown region of its voltage-current characteristic curve. Unlike regular diodes, which are designed to allow current to flow in one direction and block it in the reverse direction, Zener diodes are specifically engineered to have a controlled breakdown voltage in the reverse direction.
When a Zener diode is operated in reverse bias beyond its breakdown voltage (also known as the Zener voltage), it starts to conduct in the reverse direction. This characteristic makes Zener diodes valuable in a variety of applications, primarily related to voltage regulation and voltage reference.
It's important to choose a Zener diode with the appropriate breakdown voltage for your specific application. Zener diodes are available in a wide range of breakdown voltages and power ratings to suit different requirements.
