It is available in a TO-220 package and is composed of a high resistivity silicon body for the junction layer. It has a good temperature coefficient with a guarantee of the nominal breakdown voltage and a maximum reverse current.

Typical Applications

1N5916C Zener Diode is mostly used in voltage regulation. It stands as an ideal device for applications that require both linear and reverse droop over temperature. Its low leakage current ensures that any noise interference is minimized so it\'s a good choice for noise suppression. It is also used for voltage monitoring and protection against reverse voltage transients such as transient overvoltage seen in telephone lines, or in the lower voltage spikes created on the automotive battery. 1N5916C is available with a variety of capacitance values, and power ratings in order to meet the specific requirements of any application.

Working principle

1N5916C Zener Diode works as a voltage regulator when reverse biased. It has a built-in diode junction which supports reverse current flow. When connected in the reverse bias mode, a greater amount of voltage is applied and the voltage across the junction increases until the zener voltage is reached. At this point the current across the junction becomes constant thus resulting in a stable voltage at the output. The voltage across the junction is maintained constant irrespective of the input voltage fluctuations.

1N5916C is also used for overvoltage protection. At startup, the high voltage applied across the diode junction results in sudden breakdown and thus helps protect the semiconductor device from the sudden voltage surge. It can also be used to limit the voltage across a system so that it does not exceed the predetermined threshold. At maximum breakdown voltage, 1N5916C Zener Diode can handle up to 5.6V.
