Application Field

GLL4749-E3/97 diodes are suitable for both industrial and consumer applications. These diodes are commonly used in automotive, consumer electronics, computer, communication and other industries. They can be used in voltage regulation, overvoltage and overcurrent protection, polarity protection, noise reduction, static electricity, signal switching and various other applications.

Working Principle

GLL4749-E3/97 diodes use the Zener effect to regulate current flow by allowing the device to operate in the reverse breakdown region when it is exposed to an appropriate voltage. When a forward bias is applied to this device and the voltage reaches a certain level, the device will undergo a transition to the reverse breakdown region. This reverse-bias potential difference allows electrons to be injected into the P-type region and recombine with the existing holes, resulting in a decrease in voltage and current flow. The Zener diode has a low reference voltage, which is determined by the dopant concentration, the thickness of the junction, and the external series resistance. At a specific point, the device\'s reverse current-voltage curve produces a knee-like shape. This knee slip point is called the Zener breakdown voltage and the device works reliably within the specified voltage range.
