VI20100CHM3/4W is a diode array comprised of two individual diodes housed in a single package in order to protect loads from any reverse current (in opposite direction) in the circuit. This type of diode array is specially designed for switching regulators, for voltage level shifting and for other discrete power devices. It is constructed with a bypass voltage of 10V with a forward current of 1A and is capable of blocking reverse currents up to 10A.

A VI20100CHM3/4W is a surface mount device built on a printed circuit board that requires an external heat sink and provides an industry-standard electrical interface compatible with industry-standard terminations and mounting. The array is typically made of two special plastic-encapsulated PN junction rectifier diodes.

The main application field of the VI20100CHM3/4W is to protect against reverse current. This can be accomplished by a rectifier connected to a reverse polarity voltage source. In this instance, the diode array will act as a rectifier, and all of the reverse current is blocked from the load in order to protect the load from over current damage caused by the reverse voltage. In this way, the VI20100CHM3/4W acts as a protective diode for the load.

The VI20100CHM3/4W also has a wide range of other application fields. It can be used as a voltage level shifter in an AC-DC converter circuit, for example, which is a common application for the diode array. It is also used for power supply regulation and clamping in switched mode power supplies (SMPS), or for soft-starting DC motors. Furthermore, it can be used to reduce the inductive kickback caused when inductive loads connected to AC power lines are switched off.

The working principle of the VI20100CHM3/4W is based on the PN junction rectifier. It works by allowing current to flow in one direction only, while blocking current in the opposite direction. In this way, any reverse voltage or current applied to the device is blocked, protecting the load from the effects of any reverse current. The diode array’s construction allows for higher absolute voltage to be blocked, and for higher peak reverse current. Additionally, the diode array works at a much lower operating temperature since the two elements are housed in the same package.

In conclusion, the VI20100CHM3/4W is a type of diode array used to provide protection to multiple devices from reverse current in circuits powered from AC sources. It works by using a PN junction rectifier to allow current to flow in one direction only, while blocking current in the opposite direction. The wide range of uses for the diode array make it suitable for multiple applications, ranging from protection against reverse current, voltage level shifting, power supply regulation and clamping, to soft-starting DC motors. Moreover, its construction allows for higher absolute voltage to be blocked, higher peak reverse current, and a much lower operating temperature than other individual diodes.
