Introduction

The TZMB4V7-GS08 diode is a Zener diode suitable for a variety of applications. It is a part of a larger series of diodes from Toshiba, each type having different range of ratings. The TZMB4V7-GS08 diode falls into the Zener diode family, and is a single diode. As the name implies, this diode is manufactured and sold by Toshiba, who is a major semiconductor electronics supplier.

Application Field

The primary applications of the TZMB4V7-GS08 diode are in the generation of low voltage regulated power supplies, such as laptop and mobile device chargers, storage devices, and other such electronic devices. It also finds use as a voltage reference diode that maintains a consistent voltage regulator output from PC motherboards and other consumer electronics products.The diode is capable of operating at relatively high voltages, up to a peak inverse voltage (PIV) of 400V. This allows it to be used in a variety of applications that do not need as much voltage control as other Zener diodes. It is also available in very small package sizes, with a lead-less metal-oxide semiconductor (LMOS) package that is less than 1mm thick. This makes it well-suited for use in modern, compact electronics products, such as portable devices and laptops.

Working Principle

The TZMB4V7-GS08 diode operates on the principle of a Zener diode. It is a reverse-biased diode that is capable of conducting current in either direction. However, when the diode is reverse-biased, it will not allow the current to flow in one direction until its breakdown voltage is exceeded. Once the breakdown voltage is reached, the current can be conducted in either direction.The breakdown voltage of the TZMB4V7-GS08 diode is 4.7V, so it can be used to regulate voltages of up to 4.7V in an application circuit. When the voltage across the diode exceeds 4.7V, it will begin to conduct current, which will be regulated at 4.7V. This allows the diode to act as a voltage regulator, keeping output voltages stable and within a certain range.

Conclusion

The TZMB4V7-GS08 diode is a single Zener diode with a breakdown voltage of 4.7V. It is suitable for low voltage regulated power supplies, laptop and mobile device chargers, storage devices, and other such applications. It is also available in a very small package size, making it well-suited for use in modern, compact electronics products. Its ability to regulate voltages of up to 4.7V makes it an ideal voltage regulator for a variety of applications.
