UDZVTE-177.5B Discrete Semiconductor Products

Introduction

The UDZVTE-177.5B is a single Zener diode designed to offer precise regulation of low to medium power. It is mainly used for overvoltage protection, grounding and preventing fluctuations in the output of devices such as transformers.

Application Field

The UDZVTE-177.5B offers a wide range of application fields:

• Overvoltage protection for transformers, displays, circuits, motors and converters
• Power supply stabilization
• Audio and video protection
• Grounding and control circuits
• Voltage buildup
• Clamping circuits

Working Principle

The UDZVTE-177.5B is a single Zener diode, meaning it has a single junction which allows it to maintain a constant voltage. When the voltage across the diode is less than the Zener voltage, the diode acts like a normal diode and conducts current in either direction. But when the voltage across the diode is greater than the Zener voltage, the diode begins to conduct strongly in one direction and offers only weak resistance in the other. This maintains a constant voltage across the diode.

The UDZVTE-177.5B is designed to protect circuits against a wide range of input voltage, from the peak voltage of the mains supply to the low voltage of a battery. Its low power rating makes it suitable for many different applications, including audio and video protection, power supply stabilization, as well as many other uses.
