Introduction

TZM5256C-GS08 is a single zener diode, which is typically used as a voltage regulator for various applications.

Application Field

The TZM5256C-GS08 is widely used in various electronic and electrical projects, including circuits that require constant voltage regulation and protection from reverse loading or accidental shorts. It is designed to provide a guaranteed breakdown voltage with a closed-loop feedback feature that ensures that it remains within a specified operating range. Additionally, due to its wide temperature range, it is also suitable for use in automotive and aerospace applications.

It is often used in low voltage power supplies, voltage references, and as protection devices against reverse loading and accidental shorts. It is also suitable for use in circuits where the parameters of the circuit such as frequency, temperature, and load current may affect the output voltage. Additionally, it is exceptionally well-suited for portable battery-powered circuits.

Working Principle

The working principle of TZM5256C-GS08 is based on the principle of electron tunneling between two electrical junctions. This diode consists of two terminals, the anode and the cathode, which are surrounded by a semiconductor material. When an external voltage is applied across the terminals, electrons from the anode tunnel through the valence band of the semiconductor material to the cathode. The electrons must have a minimum energy greater than the bandgap in order for the tunneling action to take place. This energy translates into a voltage drop across the terminals. Depending on the polarity of the applied voltage, either the electrons or the holes are created and the diode is forward biased or reverse biased, respectively.

When it is forward biased, the voltage drop across the terminals is minimal and the diode acts as a resistor. Upon reaching the breakdown voltage, the diode switches to its breakdown region where it is reverse biased and the potential barrier within the valence band is eliminated. As a result, current can flow freely through the diode and the voltage across the terminals is regulated as long as the forward current does not exceed the maximum specified current rating.

Conclusion

In conclusion, the TZM5256C-GS08 is a single zener diode, which is designed to provide a guaranteed breakdown voltage with a closed-loop feedback feature. It is suitable for a variety of applications, including low voltage power supplies, voltage references, protection against reverse loading and short circuits, and automotive and aerospace applications. Additionally, its working principle is based on the principle of electron tunneling between two electrical junctions.
