A 1N5347/TR12 is a single Zener Diode manufactured by ON Semiconductor. It is designed for use in different applications such as voltage stabilization, voltage regulation, overvoltage protection, reverse polarity protection and other alike applications. In this article, we will discuss the application field and working principle of 1N5347/TR12.

1N5347/TR12 is a 3.3 V 6.0 W Zener Voltage Regulator Diode with a T-R version. It has a maximum reverse power dissipation rate of 12 W at an ambient temperature of 25 °C and an operating junction temperature range of -40 °C to +150 °C. It has an ambient temperature range of -55 °C to +150 °C and an operating junction temperature range of -55 °C to +200 °C. It has a maximum forward voltage drop of 1.0 V at a rated current of 5.0 A. The diode is available in a standard TO-220 package.

1N5347/TR12 is mainly used for voltage stabilization, overvoltage protection, reverse polarity protection, transient voltage suppression and voltage regulation. It can be used to limit the maximum voltage applied to a device or circuit. It is also used as a clamping device in protection of transistors, integrated circuits and voltage regulators from overvoltage. It also helps to suppress noise in electronic circuits.

The working principle of 1N5347/TR12 is based on the Zener effect. This is 3.3 V Zener Diode, which means that it has a Zener voltage of 3.3 V when the current is flowing in the reverse direction. The maximum reverse voltage rating is rated at 3.3 V and the maximum current rating is rated at 5 A.

When the voltage is below the Zener voltage, the diode behaves like a normal diode and the current flows in a single direction. When the voltage is increased and becomes equal or close to the Zener voltage, the current also increases. This voltage is known as the reverse break down voltage and is usually lower than the rated Zener voltage.

One of the most important features of the 1N5347/TR12 is that it can provide voltage regulation. This helps to ensure that the voltage applied to the device or circuit remains constant. This helps to increase the life of the device or circuit as it is not subjected to extreme voltage fluctuations. The 1N5347/TR12 also helps to provide reverse polarity protection by clamping any reverse voltage to a safe level.

In summary, the 1N5347/TR12 is a single Zener Diode manufactured by ON Semiconductor. It is designed for various applications such as voltage stabilization, overvoltage protection, reverse polarity protection and transient voltage suppression. It works on the principle of reverse break down voltage, also known as the Zener voltage, and is capable of providing voltage regulation and protecting the device from overvoltage.
