SZBZX84C27ET3G

The SZBZX84C27ET3G is a P+ type silicon planar Zener diode which is designed to ensure low noise levels, low reverse leakage, low forward voltage drop and low temperature coefficient at standard operating conditions. It is an ideal solution for applications that require high reliability and dynamic stability. This Zener diode is suitable for use in most application fields, including power converters, cellular base stations and digital systems.

Applications

The SZBZX84C27ET3G can be used in applications where a limited number of breakdowns per minute is required due to limits imposed on reverse current for the device. Other applications include overvoltage protection, surge protection, transient protection, EMC protection, as well as negative rail and clamp circuits. The SZBZX84C27ET3G is also used in voltage regulation applications, as well as industrial control feedback, temperature controller feedback and feedback loop to maintain stability.

Working Principle

The SZBZX84C27ET3G operates on the principle of a Zener diode, in which the current flowing through the diode is oppositely directed and of constant magnitude, creating a reverse breakdown voltage. At the breakdown voltage, the current is limited and increases very slowly. This creates a stable voltage and current leading to a consistent output voltage. The Zener voltage and current are held constant as long as the temperature and current are within a specified range.

The SZBZX84C27ET3G Zener diode is constructed from a specifically designed P+ type silicon planar chip and features a guard ring for high reliability. The guard ring helps protect the junction from electrical overstress and overcurrents, producing a high immunity to environmental conditions. The device incorporates a higher internal resistance, which will reduce the temperature coefficient and leakage current. The high operating temperature and high-grade silicone make the device suitable for rugged and long life applications.
