Introduction

The BZG05C3V9-M3-18 is a diode from the family of Zener single diodes. It is a compact, low voltage diode developed to be used in high speed control, signal processing, and other applications that require an accurate, high performance, and reliable signal control.

Application Field

The BZG05C3V9-M3-18 offers a wide range of high speed applications such as EMC testing, signal switching, signal conditioning, power management and other related applications. This diode has also been successfully applied for low power applications such as automotive, broadcast, mobile, and other related communications. It can be used in environments that need to consistently maintain control of electrical signals that have a high frequency.

Working Principle

The BZG05C3V9-M3-18 uses a reverse-biased Zener junction to achieve its purpose. When a voltage larger than the threshold voltage (Vz) is applied across the diode, the electrons and holes on the junction start recombining thus, releasing energy in the form of a diode current (Iz). This current flows through the diode junction and eventually is rectified, providing the desired effect.

The reverse bias of the BZG05C3V9-M3-18 diode reduces its output capacitance, making it more suitable for high frequency applications. It also reduces the internal power dissipation, allowing the diode to operate in a more efficient manner.

The BZG05C3V9-M3-18 diode also enables the user to have greater control on the signal’s level by providing a uniform output edge. This is done by providing a narrow voltage window (Vz) and a predictable current flow through the diode.

The BZG05C3V9-M3-18 diode has a wide range of performance benefits, including low losses, high speed, high accuracy and reliability, low input voltage droop, and low power dissipation.
