1N5340C/TR12 is a 3.4V Zener diode, and it is included in Diodes - Zener - Single category. It is a three-terminal axial lead, hermetically sealed, with PbSn or PbSnAg termination. With the breakdown voltage of 3.4V, this diode has a power dissipation rating of 500mW.

The main application of 1N5340C/TR12 are in low power reverse voltage protection, polarity indicator or voltage testing and clamping application, to stabilize voltage.

The 1N5340C/TR12 diode features surge capability of 400Watts and they are leads with nickel plated copper, with the hermetically sealed case top to avoid moisture and dust coming inside.

The working principle of 1N5340C/TR12 is through the Zener process. Like all Zener diodes, it has a reverse voltage breakdown behaviour, with a slope increasing as the voltage goes up. If a voltage higher than 3.4V is applied between the two terminals, electrons are projected across the junction, creating a current that flows in the reverse direction and assisting the breakdown, then the current starts flowing with just modest increasing on the applied voltage.

The dynamic resistance of 1N5340C/TR12, defined as the reciprocal of the slope dV/dI at the Zener voltage, is about 0.4 ohms. This dynamic resistance of 1N5340C/TR12 is very low, meaning that the regulation factor keeps the output voltage low and constant, regardless of the load.

When forward voltage is applied, the current passing through is directly proportional with the applied voltage. However, when the applied voltage is between 0 and 3.4V, the current is almost 0. This means that the application of 1N5340C/TR12 Zener diode is useful when the ideal voltage is 3.4V, and it helps detecting any current passing through and avoid any excess of current running through the circuit.

1N5340C/TR12 is a leakage current of only 0.2mA maximum and its voltage tolerance ranges between 25.7V up to 5%. Its function can be classified as low power reverse voltage protection, polarity indicator or voltage testing and clamping application.

In terms of its forward voltage, 1N5340C/TR12 uses about 0.4V. This is slightly higher than 1N914, the other Zener most commonly used, but the difference is not big enough to damage the components on the circuit.

The 1N5340C/TR12 diode also has low dynamic resistance, 0.4 ohm, which is an important feature for devises that need constant output voltage. It also has an average reverse current of only 2uA, less than 1N914 and other Zener diodes.

Since the 1N5340C/TR12 diode is bead sealed and come with leads in nickel plated copper, it is reliable and can be used in harsh environment without getting damaged due to dust, humidity, moisture or temperature changes.

Finally, it is important to note that 1N5340C/TR12 has high surge capability of 400Watts, meaning it can handle sudden voltage peaks without any problems. This ensures that the device can could be used in applications in which high voltage transients are possible.
