Diodes are an integral part of electronic devices that comprise a wide array of technologies. Within the category of diodes, Zener diodes are electronic components designed to limit the voltage applied to a particular circuit whichever way the current passes. Zener diodes are classified further into single and dual diodes.

The 1N4616UR is a single Zener diode manufactured by Central Semiconductor and its main application field is protection against overvoltage. Its primary function is to allow current to flow through it in one direction, while also providing a resistance to current flowing in the opposite direction. This results in a steady voltage applied across the device, regardless of the amount of current passing through or the direction it travels in.

Normally Zener diodes are produced in voltage grades ranging from 2.4V to 61V, depending on the application type. The 1N4616UR diode is available in a reverse breakdown voltage rating of 6.2V. This particular device exhibition a low power rating of 0.5W, a maximum average forward current rating of 200mA and a 50V working peak reverse voltage rating.

The operational working principle of the 1N4616UR Zener diode is similar to any other Zener device. When the voltage supplied to it is lower than its rated breakdown voltage, the diode behaves like any other common diode, allowing current to pass through it when the correct forward bias is applied.

However, when the voltage applied across the diode reaches its rated breakdown voltage, the diode conducts in the reverse direction. This is due to the strong electric field that is generated just above the P-N junction region. This field is strong enough to break down the barrier across the junction allowing current to pass in both directions, regardless of the direction of the applied voltage.

The voltage across the 1N4616UR diode remains roughly constant due to the exponential relationship between the current and reduction of voltage across the device. This gives the Zener diode its characteristic of providing a fixed low voltage reference point. This voltage reference is useful in several different types of applications ranging from voltage regulation in current limiting circuits and feed-back loops, to communication interface deriving.

The combination of the 1N4616UR low voltage rating and its high peak reverse voltage, makes it ideal for protective circuit purposes. This device is commonly used as part of an overvoltage protection circuit to ensure surges of high voltage do not damage components or integrated circuits.

In conclusion, the 1N4616UR diode is a single Zener diode produced by Central Semiconductor, designed to limit the voltage applied to a particular circuit. The device is available in a reverse breakdown voltage rating of 6.2 volts and a working peak reverse voltage rating of 50 volts. Its main application field is overvoltage protection and its operational principle relies on a strong electric field breaking down the barrier of the P-N junction, allowing current to pass through in both directions at the same time.
