TVS (Transient Voltage Suppressor) diodes are electronic components, akin to any other diode, with a more specialized function. Unlike run-of-the-mill diodes, which chiefly carry current in one direction and block current in the opposite direction, TVS diodes also offer superior protection against surges of energy. There are many different types of TVS diodes, and 15KPA36C is one of them.

Application Field

The 15KPA36C is a dual diode. As such, its primary use is protecting equipment against large voltage spikes. It typically consists of two similar diodes, one of which is usually a Zenor diode and the other a Transient Voltage Suppressor (TVS) diode, which are connected to a common point. It is designed to protect electronic components, including semiconductors, against voltage transients. It can also be used to clamp surges to safe levels, retain stable voltage, suppress signal over-voltages, and ensure power supply switch-on safety.

This diode is often used to protect sensitive electronic components from voltage spikes which can occur in automotive applications. It can be used for protection against voltage spikes in automotive and power supplies, voltage clamping, as well as signal transients

Working Principle

The 15KPA36C is a zener diode with another TVS diode connected to it. The main purpose of the two diodes is to suppress transients. A zener diode works by maintaining a constant voltage across its output even when the input voltage varies. This is because when the input voltage rises too high, the Zener diode starts to conduct current that is in opposite direction of the primary current flow, thus diverting much of the voltage away from the device that is being protected.

On the contrary, the TVS diode simultaneously starts to pass current in the same direction of current flow through its junction when the input voltage rises too high. This helps to protect the protected device from further voltage increase. Overall, the two diodes together helps to protect the device from voltage transients that can render the device inoperable.

Apart from protection against voltage transients, the 15KPA36C diode also ensures power supply switch-on safety. This is because as the input voltage rises too high, the diode will help divert much of the voltage away from the device, by conducting current in opposite directions.

In the 15KPA36C diode, the two diodes are connected to a common point. This helps to enhance the protection provided by the diode, as it is able to absorb larger amounts of energy due to its increased size. The two diodes together are able to provide a higher level of protection against transients, surges, and over-voltages.

Conclusion

The 15KPA36C is a dual diode usually consisting of two similar diodes, one of which is usually a Zenor diode and the other a Transient Voltage Suppressor (TVS) diode. It is typically used to protect electronic components, including semiconductors, against voltage transients. The two diodes are connected to a common point, making the diode more capable of absorbing larger amounts of energy compared to standard diodes. It can also be used for power supply switch-on safety, as well as clamping surges to safe levels.
