SDUR1520CT Application Field and Working Principle

SDUR1520CT is a rectifier diode array product manufactured by Semtech. It is applicable in major worldwide communications rectifier designs, where high reliability and stability of performance are essential.

SDUR1520CT is designed to address the requirements of critical telecommunications applications and consists of four pairs of common anode, rectifier diodes connected in series. It is a high power diode, capable of handling up to 200mA of current, 250V of voltage, and up to 400W of power.

The SDUR1520CT diode array has an extremely wide operating temperature range, as low as -60°C and as high as +150°C compared to some other diodes in the same category. Its excellent temperature performance is enabled by its low leakage current and peak junction-to-case thermal resistance of 0.5K/W. Finally, its high reliability is achieved by its low reverse bias catastrophic failure rate of 5,000 per million.

The application field for the SDUR1520CT array is primarily in the telecom industry, where it is needed for Direct-to-Home (DTH) applications, as well as for ADSL/VDSL modem applications. It is also used in other areas of power conversion, such as off-line power supplies and in general rectification. The diode array is suitable for a wide range of telecom applications in the telecom industry.

In terms of the working principle of the SDUR1520CT, it functions as a controlled rectifier. In a controlled rectifier, the intended load value is SET using a series of adjustable diodes. These diodes, or the controlled rectifier, are designed to provide a load shedding current that reduces in proportion to load voltage. This load shedding current provides protection against over-current or over-voltage conditions, ensuring that the load remains consistently constant.

The SDUR1520CT diode array is the perfect solution for telecom rectification applications, as it is designed for the high power and performance demands of these demanding applications. Its wide operating temperature range makes it suitable for use in remote sites, and its high reliability ensures that it will operate reliably in particularly harsh environmental conditions.
