A Zener Diode is an electronic component which can use to make a very simple voltage regulator circuit. This circuit enables a fixed stable voltage to be taken from an unstable voltage source such as the battery bank of a renewable energy system which will fluctuate depending on the state of charge of the bank.

The 1N4742A is a versatile and reliable Zener diode that can use in a wide variety of electronic applications. It is a popular choice for hobbyists and professionals alike.

12V 1W Zener Diode 1N4742A is a Zener Diode for general use and also suitable for many different applications. Color band denotes the cathode end polarity.

The 1n4742 is a Zener diode use for clipping circuits with high power rating. The Zener diode conducts in both directions i.e. forward-biased condition and reverse-biased condition.

The Zener diode operates just like the normal diode when in the forward-bias mode, and has a turn-on voltage of between 0.3 and 0.7 V. However, when connected in the reverse mode, which is usual in most of its applications, a small leakage current may flow.
