1N3995RA Application Field and Working Principle

Introduction

The 1N3995RA is a type of zener diode designed for use as a voltage regulator or for clamping of negative voltage transients. It is a single diode with a breakdown voltage of 9.1V and a maximum reverse current of 5mA. The device is encapsulated in a standard two-terminal leaded package, making it easy to integrated into a variety of circuit designs.

Application Field

The 1N3995RA is primarily used in circuits that require a regulated voltage or to clamp negative voltage transients. It is used in applications such as voltage regulators, voltage references, DC/DC converters, and automated test equipment. It is also used in many consumer electronics, such as mobile phones, tablets, and home appliances. It is an ideal solution for many circuit designs with its small size, low cost, and ability to dissipate heat. The 1N3995RA is designed to operate over a wide temperature range, from -40°C to +125°C.

Working Principle

When a small reverse bias is applied to the 1N3995RA, an exponential increase in reverse current is observed. At a certain bias voltage, called the “Zener voltage”, the current suddenly increases dramatically – this marks the point of breakdown. The Zener voltage is maintained at a constant value and the current that is passing through the device is referred to as “Zener current”. The 1N3995RA is designed to maintain a constant Zener voltage of 9.1V across a wide range of temperatures. It is also designed to ensure that the Zener current does not exceed 5mA.

Conclusion

The 1N3995RA is a popular diode used in a variety of circuits to provide voltage regulation and clamping of negative voltage transients. It is designed to maintain a constant Zener voltage of 9.1V across a wide temperature range and offers a maximum reverse current of 5mA. The device is encapsulated in a standard two-terminal leaded package for easy integration into various circuits. It is an ideal mechanical partner for many applications due to its small size, low cost, and ability to dissipate heat.
