1N5226A Application Field and Working Principle

Introduction

1N5226A is a single zener diode specifically designed for general-purpose applications, such as voltage reference and voltage regulation in electronic circuits. It offers good quality and reliable performance, so it is widely used in the field of electronics. 1N5226A can sustain up to 1W power dissipation.

Application Field

1N5226A is most commonly used in voltage reference and voltage regulation application. It can be used in power supply design to maintain a stable output voltage. It is also suitable for voltage clamping and surge protection application. Other application includes clipping, clamping, peak detecting, AC zener applications and sampling circuits.

Working Principle

1N5226A is like other Zener diodes, which has a junction between p-type and n-type semiconductor materials. This diode utilizes the process of reverse breakdown when apply a reverse bias voltage over a certain threshold that varies according to the specific zener voltage. The zener voltage of the 1N5226A is 5.1V, when the reverse bias voltage side is larger than 5.1V then the diode becomes electrically conductive. The electric current flows through the diode while the voltage across diode remains at 5.1V, which is known as Zener Voltage.

The reverse breakdown voltage is the key factor if 1N5226A is suitable for the design application. The temperature coefficient of the breakdown voltage is important when designing the power supply. The thermal stabilization of 1N5226A is acceptable and suitable for most design application.
