SDHN7.5K Application Field and Working Principle

Diodes, rectifiers and arrays are widely used in a variety of fields due to their versatile applications.SDHN7.5K, belonging to this category, is an ideal high power rectifier with excellent electrical characteristics. Commonly used for power supply, communication, and motion control applications, this diode array offers a reliable, low cost solution for rectifying AC power to DC power.

The SDHN7.5K array is especially suitable for high-power rectifier applications in the power, communications, electrical and manufacturing industries. The diode array provides a broad range of current ratings, ranging from 7.5A to 50A, and a withdrawal range of 1.8V to 20V. This flexibility enables the device to be used in a variety of rectifier and power supply applications in the industrial and commercial sectors.

The SDHN7.5K array uses a combination of high-efficiency and high-current fast and super-fast silicon rectifier diodes. The diodes are housed in an anodized aluminum housing, providing excellent heat dissipation and protection. The diode array is a single package containing four discrete rectifier diodes, packaged in a single chip. The array operates in a range of different voltage and current ratings and offers individual circuit protection for each diode.

The working principle of the SDHN7.5K array is based on the use of high-speed silicon rectifier diodes. When an AC sinusoidal voltage is applied to the anode of the diode, current flows in both directions, alternating between positive and negative. However, the diode rectifies this alternating current so that only current in one direction can flow, thus providing a DC output. The diode array also ensures that each diode is not over-stressed by allowing some current to flow in parallel with individual diodes.

The diode array also includes protective circuitry which prevents overvoltage or reverse current from damaging components. This protective mode operates by limiting the current and voltage flowing through each diode, ensuring reliable operation over a wide temperature range. The SDHN7.5K also includes integrated transient suppression, which helps minimize switching noise and electromagnetic interference.

The combination of its wide current ratings, custom protection and transient suppression mechanism makes the SDHN7.5K diode array ideal for a wide range of rectifier applications. The diode array can be used in power transmission systems, AC/DC power converters, switch mode power supplies and in domestic appliance control, providing high performance, reliability and easy installation.
