A 1N5359/TR8 is an axial-lead Zener diode, meaning that its anode and cathode leads both project out of the same side of the package. As with all diodes, it limits the direction of current flowing through it: current flows freely through it in one direction, however current in the other direction, though technically still possible, is heavily resisted. However, whereas a normal diode\'s one-directionality is itself largely unchanging, the 1N5359\'s conduction in the reverse direction is heavily dependent on the voltage across it: up to a certain voltage the conduction remains low, however, once the Zener voltage is exceeded, conduction rapidly increases.In practical terms, this means that the 1N5359/TR8 can be applied in any circuit where a reliable and stable voltage needs to be maintained, a setting which the device will maintain regardless of any current drawn. On the other hand, if the voltage drops too far, the device will abruptly increase conduction and therefore draw increasing amounts of current until the required voltage is restored.

The most obvious application in which the 1N5359/TR8 excels is within voltage regulation circuits. Since the device responds to the input voltage by adjusting its conduction accordingly to ensure the target voltage is maintained, it is a very usefull tool in stabilizing system voltages which are subject to power fluctuations which would otherwise lead to output instability. In addition, it can also be used to construct circuits that are capable of responding to changes in ambient temperature, compensating by adjusting the output accordingly; such applications are frequently seen in automotive electrics. Furthermore, the 1N5359/TR8\'s relatively large Zener resistance ensures that only small current flows, so for applications where the most efficient use of current is needed, the device can prove invaluable.

In terms of its working principle, the 1N5359/TR8 behaves much like any other type of diode. Its axial lead configuration allows it to be integrated directly into a circuit, where it will provide reverse-biased protection if its Zener voltage is surpassed. Its Zener voltage is determined by the precision of its construction; in the case of the 1N5359/TR8, its Zener voltage is 5.6V, allowing it to be utilised as a general-purpose voltage regulator for up to 5.6v applications. However, should a diode with a higher Zener voltage be required, the 1N5359/TR8 is available in alternate versions ranging from 2.4V to 75V.

It is also important to note that, as with any other type of diode, the 1N5359/TR8 will generate a relatively small amount of noise when current is flowing through it in either direction. This noise can be a problem in certain applications, and in such cases it may be desirable to use an alternative device in order to reduce or eliminate the interference; fortunately, other zener diode types, such as the 1N5360/TR9, are available.

To summarise, the 1N5359/TR8 is a general-purpose axial-lead Zener diode with a 5.6V Zener voltage, making it suitable for use in voltage regulation, temperature compensation and noise reduction applications. As the device is capable of reliably maintaining a specific voltage regardless of any current drawn, and due to its relatively low current consumption, it is a popular choice for any project requiring a reliable and efficient voltage regulator.
