Diodes - Rectifiers - Single: AR4PJ-M3/87A Application Field and Working Principle

A diode is the most common type of semiconductor device, and it is fundamental to the electronic industry. Diodes are typically used for rectifying, steering and preventing excessive power from flowing in the wrong direction. The AR4PJ-M3/87A from CASCOS is an ultra-compact, electrical fast-acting, single-phase, surface-mount bridge rectifier designed primarily for applications such as encoders, touch pads, and security systems. This article provides an overview of the application field and working principle of the AR4PJ-M3/87A.

Application Fields of the AR4PJ-M3/87A

The AR4PJ-M3/87A is designed primarily for power supply designs requiring low voltage drops and high efficiency. The device has a maximum forward current of 200mA, making it suitable for use in applications that require fast electrical response times and precise control, such as encoders, touch pads, and security systems. The AR4PJ-M3/87A is also suitable for driving transistors, thyristors, and transformers, and for motor control for low voltage and current applications.

Working Principle of the AR4PJ-M3/87A

The working principle of the AR4PJ-M3/87A is simple but effective. The device consists of two half-bridges, each composed of five diodes in a bridge configuration. When AC input power is applied, the diodes of each half-bridge will alternately conduct and block current, resulting in a pulsed DC output. This pulsed DC output is then filtered and rectified, resulting in a stable DC output.The AR4PJ-M3/87A can be operated with voltage inputs ranging from 9 to 30 volts. When powered, the device will draw approximately 8mA of current and have a maximum reverse recovery time of 25ns. The device is also rated for peak reverse voltage (VRRM) of 800 volts.

Conclusion

The AR4PJ-M3/87A from CASCOS is a high performance, single-phase, surface-mount rectifier designed for use in applications such as encoders, touch pads, and security systems. The device has a maximum forward current rating of 200mA and will draw approximately 8mA of current when powered. The working principle of the device is based on the bridge configuration of two half-bridges, each composed of five diodes. When AC input power is applied, the diodes of each half-bridge alternately conduct and block current, resulting in a pulsed DC output. This pulsed DC output is then filtered and rectified to produce a stable DC output.
