Introduction

The TZMB43-GS18 diode is a type of single-phase, low-voltage Zener diode produced by general semiconductor. It is intended for use in a wide variety of applications in the field of electronics. This diode is used in applications that require the regulation of a high-voltage power supply in order to prevent overloads, surges, and other issues. It is constructed of an NPN silicon epitaxial structure and a semi-insulated package, providing excellent performance and reliability.

Physical Appearance

The TZMB43-GS18 diode is available in two different package types, the TO-220 package and the SOT-223 package. The TO-220 package is composed of a black plastic body and a silver-plated copper tab, with a total diameter of 17.0 millimeters. The SOT-223 package is composed of a black epoxy resin body and a copper lead frame with a total diameter of 8.2 millimeters. The associated marking on the diode is a white “GS18”.

Rating and Characteristic Features

The TZMB43-GS18 diode has a rating of 8 volts (V) in DO-220 package, an IZT of 5mA, a TJ of 125 degrees Celsius (°C) and a Ptot of 500 mW. Its characteristics include a maximum memory of 800 degrees Celsius (°C), a minimum breakdown voltage of 6 volts (V) and a maximum series resistance of 2 ohms (Ω) at a temperature of 25 degrees Celsius (°C).

Application Field and Working Principle

The TZMB43-GS18 diode is commonly used for regulating high-voltage power supplies. For example, it is used in applications such as surge protectors, voltage regulators, and other power supplies. The diode works by using the electrical properties of a crystal diode to regulate the voltage of a power supply. This diode allows a current to flow in one direction while blocking the current from flowing in the opposite direction. As the voltage of the power supply begins to increase, the diode begins to conduct and limits the voltage of the power supply. This is called the "Zener Effect," which is how the diode regulates the voltage of the power supply.

Conclusion

The TZMB43-GS18 is a single-phase, low voltage Zener diode produced by general semiconductor designed for a variety of applications in the field of electronics. It comes in two different packages and has a rating of 8V and a IZT of 5mA. It is used for regulating high-voltage power supplies and works by utilizing the electrical properties of a crystal diode to limit the voltage of the power supply.
