JAN1N4938-1

Diodes play an essential role in a variety of electronic circuits, such as rectification and signal switching. Among them, rectifiers, such as the widely used JAN1N4938-1, are one of the types of diodes. This article will introduce the application field and working principle of JAN1N4938-1.

JAN1N4938-1 Overview

JAN1N4938-1 is a type of single diode in a DO-15 small plastic package. It is especially designed for general-purpose rectification applications, such as small power supplies, inverters and other high-frequency rectification circuits.

JAN1N4938-1 features a high current rating and a high temperature operating range of -65 to +150 degrees Celsius, allowing it to support operations in extreme climates. With a current rating of 1.0A and a voltage rating of 100V, it is capable of handling up to 1W of power in most rectification applications. It is also RoHS compliant and available in a variety of packages and lead forms.

Application Field

The JAN1N4938-1 is mainly suitable for high-frequency, full-wave low-loss rectification, such as small power supplies, inverters, rectification and voltage regulation of low-voltage AC power sources. Since this diode features a high current rating and high temperature operating range, it can also be used in automotive applications, such as those involving battery charging, DC motors, alternator rectification, and voltage regulation.

Principle of Work

The JAN1N4938-1 works according to the principle of rectification, which is the conversion of alternating current (AC) electrical energy into direct current (DC). This principle is based on the fact that diodes can only pass current to move in one direction. Here, the JAN1N4938-1 works as a barrier, preventing current from traveling back the other direction.

When an AC power source is connected to the diode, the diode will only allow current to travel in one direction, while blocking the flow of current in opposite direction. This allows the previously alternating current to be converted into a direct current as it passes through the diode.

Conclusion

The JAN1N4938-1 diode is a widely used single diode for rectification applications, due to its high current rating, temperature operating range and availability in various packages. It works according to the rectification principle, which converts alternating current into a direct current. It is mainly suitable for small power supply rectification, inverter applications and other high-frequency rectification circuits.
