Introduction

MMBD1503A-D87Z, part of a diode-rectifier array family, is a bidirectional diode array with an integrated diode array for use as a low voltage signal device by Arra-Semiconductor. The device is used in multiple signal applications including signal conditioning, signal pass-through, switching, and level shifting. It provides signal switches for both signal source and load to ensure optimal performance.

Application Field

MMBD1503A-D87Z is suitable for use in a wide variety of signal applications from switching and level shifting to signal conditioning and signal pass-through. It is typically used to provide signal switches for both signal source and load to ensure optimized performance. Examples of applications include Powerline Communication (PLC) systems, telecom systems, and medical/industrial equipment.

It can also be used as a low-power, low-current signal diode array for use in low voltage, high frequency operations, such as switching applications; level shifting; optical communication; and more.

Working Principle

The MMBD1503A-D87Z provides an integrated bridge arrangement of series connected pairs, enabling simple and convenient bi-directional switching between signal source and load. The device is designed to offer good resistance to reverse leakage current that can occur in signal conditioning or switching applications. It also offers low on-resistance to ensure low signal losses for optimum performance.

The counterpart of the MMBD1503A-D87Z is the MMBD1503B-D87Z, a dual diode diode array. This diode array provides additional protection to the IC’s by allowing current to flow only in one direction, thus protecting the IC from any reverse leakage current, while allowing current to flow to the load in either direction.

To ensure optimal performance, the device should be mounted on a high quality circuit board with adequate spacing between components. Heat sinking is also recommended for maximum thermal performance.

Conclusion

The MMBD1503A-D87Z diode-rectifier array provides reliable switching for both signal source and load, making it suitable for a wide range of applications. Its low on-resistance ensures low signal losses for optimal performance, while its integrated bridge arrangement allows for bi-directional switching. When properly mounted on a circuit board with adequate spacing and heat sinking and the necessary protection needed, the MMBD1503A-D87Z can provide reliable and efficient performance.
