Introduction to 1N1185

1N1185 single rectifier diodes are semiconductor devices designed for general purpose use in applications where high reliability and low cost are the primary design criteria. These diodes are designed for a wide range of applications ranging from rectification and protection to high speed switching.

Application Fields of 1N1185

1N1185 rectifiers are commonly used in battery operated systems as power supplies and as protection and rectification in low current/low voltage applications. These diodes are also used in high speed switching applications, such as in motor control circuits and ultrafast motor control systems. They are also employed in AC adapters and power converters, and are often used in audio equipment, such as amplifiers and speakers.

Working Principle of 1N1185

A 1N1185 rectifier is an electrical device which, on application of a voltage, allows current to pass in one direction but blocks it from passing in the opposite direction. This action is achieved through differences in the junction characteristics of the diode. The 1N1185 rectifier consists of a series of N-type semiconductor material and layers of P-type material. The junction between the opposing layers of N and P-type material forms the rectifying junction. When forward biased, electrons from the P-type material enter the N-type material and this results in conduction.

When the voltage is reversed the conduction is blocked and a reverse current will not flow. This blocking action of the 1N1185 rectifier is referred to as its “reverse breakdown voltage”. The breakdown voltage of a 1N1185 rectifier is typically between 5 and 15V.

Conclusion

1N1185 single rectifier diodes are reliable devices with a wide range of applications ranging from rectification and protection to high speed switching. They are commonly used in battery operated systems as power supplies and in AC adapters and power converters. The working principle of the 1N1185 rectifier is based on its junction characteristics, which allow current to flow in one direction but block it from passing in the opposite direction.
