VS-16CDH02-M3/I Application Field and Working Principle

VS-16CDH02-M3/I is a rectifier diode array often used in numerous applications. It is classified as an array because it contains multiple diodes mounted onto a single chip. It is typically used in logic circuits, and can also be used in power supply rectification, output protection, current level sensing, switching, and LED display circuits. It is intended for use in voltage converters and phase-control circuits.

The VS-16CDH02-M3/I diode array is made of four diodes in total, all connected anode-to-cathode. It is a medium-power rectifier with a continuous forward current of 1.6A and a peak surge current of 8.0A. The diodes have PN junction structures, with a nominal forward voltage drop of (at 1A) 0.85V. The reverse voltage drop is considered to be around 600V

When electric current flows through the diode, it is said to be "forward-biased". In this instance, the diodes of the VS-16CDH02-M3/I act as a one-way switch that only allows the current to flow through in one direction. This is because when forward-biased, the height of the potential barrier between the anode and the cathode is reduced, allowing electrons to pass through. By contrast, when the current attempts to flow in the opposite direction and the diode is "reverse-biased", the height of the potential barrier is increased, blocking the current.

Rectifier diodes are also used in power supply rectification and protection. Power supplies often take AC current and need to convert it to DC before it can be used. The VS-16CDH02-M3/I rectifier diode can be used in a rectifier circuit to do this. The diode blocks current from flowing in the opposite direction, allowing only the positive half-cycles through. This produces DC current by making the average of the waveform equal to zero.

The VS-16CDH02-M3/I array is also used in current level sensing and LED display circuits. In these applications, the diodes act as a current limiting device. By selectively varying the current flowing through the diodes, they can be used to control the power going to individual LEDs, ensuring they are all illuminated evenly. The diodes can also be used to control the level of current being fed into a circuit, ensuring that too much current does not overload the components.

Finally, the VS-16CDH02-M3/I array can be used in switching and phase-control circuits. In these applications, the diodes are regarded as a “controlled switch”. By controlling the voltage across the diodes, they can be used to regulate the amount of current flowing through the circuit and selectively switch elements on and off.

In summary, the VS-16CDH02-M3/I rectifier diode array is an extremely versatile, medium-power device. It is most commonly used in power supply rectification and protection, current level sensing, switching, and LED display circuits; however, it can also be used in numerous other applications. Its four diodes, each with a nominal forward voltage drop of 0.85V, serve to block current from flowing in the opposite direction and facilitate precise current level control.
