Transient voltage suppression diodes, commonly referred to as TVS, are special diodes designed to limit voltage on a circuit. They do this by providing a path of low resistance for any large spikes of current that appear on the line. Thus, the TVS is able to absorb the over voltage while returning the voltage back to the original level.

The 1N6107 is a kind of TVS with reverse breakdown voltage from 6.8V to 250V. It suits low-cost over-voltage protection applications including general interface protection, clipping circuits, ESD protection, and other applications that may be subjected to over-voltage transients. The figure 1 shows the schematic of 1N6107 TVS.

Figure 1. 1N6107 Schematic

The 1N6107 is made up of a silicon V-groove diode which exhibits a low dynamic resistance when a voltage spike is applied to it, thereby redirecting most of the excessive current away from the protected circuit. It has an internal capacitance of about 4-5pF between the anode and the cathode. Working within the limits of the IEC61000-4-2 specification it is able to achieve a high clamping voltage up to 250V for a 1µs pulse.

The working principle of 1N6107 is simple and well-known. It is based on the PN junction diode and works by allowing pulses or surges of positive or negative current to flow in a single direction. Whenever the voltage on the PN junction exceeds the breakdown voltage of the diode, the PN junction will activate the breakdown voltage, triggering a high conduction current through the diode\'s P-N junction. This conduction current can then dissipate the high voltage or surge in the circuit, thus preventing damage to the circuit.

In operation, the 1N6107 diode works by providing a very low resistance path for any excessive voltage spikes on the circuit. As the voltage increases, the PN junction conducts more current, thus dissipating the excess energy and allowing the line voltage to be returned to the original level. This dual mode protection helps to ensure that any significant over voltage is quickly dissipated and the circuit is safeguarded against damage.

As mentioned above, 1N6107 can be used in a wide range of applications including general interface protection, ESD protection, and clipping circuits, etc. Thus, it can be a great solution for applications where better surge capacity, lower capacitance, and high peak power or temperature capability are needed. Its extremely low input capacitance, low dynamic resistance, and high peak current rating make it well suited for general protection and over-voltage protection applications.

In summary, 1N6107 is a very reliable and efficient TVS that can help protect circuits from transient voltages. With its extremely low input capacitance, low dynamic resistance, and high peak current rating, it is well suited for use in a variety of protection applications. It is a great choice for applications where better surge capacity, lower capacitance, and high peak power or temperature capability are needed
