TVS (Transient Voltage Suppression) diodes are a type of electrical component used to protect power and data lines from voltage spikes and surges. They are a combination of a diode, a resistor, and an inductor that can absorb and dissipate high-voltage transients that would otherwise damage or destroy conventional electronics. The 5KP15A-G is a TVS diode from ON Semiconductor, and it is commonly used in a variety of applications to prevent damage from overvoltage transients. In this article, we will discuss the applications of the 5KP15A-G diode as well as its working principle.

Applications

The 5KP15A-G diode is typically used for ESD (Electrostatic Discharge) and overvoltage transient protection for primary and secondary telecom/telephone lines, data lines, and LAN/VLAN networks. It is also suitable for automotive, industrial, and consumer electronics applications. The 5KP15A-G can be used to protect any circuit where a voltage spike is possible, such as a USB port, audio jack, DC power input, or other type of port or connector.

This diode is also used to protect an Integrated Circuit (IC) from ESD and voltage transients. For example, it can be used to protect sensitive logic ICs from overvoltage transients or ESD transients. In automotive applications, the diode can be used to protect a variety of electrical systems from the effects of ESD transients. This includes airbag systems, instrument clusters, ABS systems, and power windows.

Working Principle

The 5KP15A-G diode works on the principle of an MOV (metal oxide varistor). When the diode is exposed to a high voltage spike or transient, the MOV will absorb the energy from the transient and become activated. The MOV will then act as a current limiting device and divert the current away from the protected circuit. The MOV will then dissipate the energy as heat and will return to its original state once the transient has passed.

The 5KP15A-G is an "unidirectional" diode, meaning that it is designed to protect against transients in one direction only. This means that the diode should be installed in the circuit in such a way that the transient voltage is applied in the opposite direction as the diode. This will ensure that the diode will be able to properly absorb and dissipate the voltage spike.

The 5KP15A-G diode is designed to withstand transients up to 15A (amperes) or 3000V (volts). It has a peak power rating of 7500W and a response time of 1 nanosecond. The diode is also RoHS (Restriction of Hazardous Substances) compliant. This means that it does not contain any hazardous materials such as lead, mercury, or cadmium.

Conclusion

The 5KP15A-G diode from ON Semiconductor is a TVS (Transient Voltage Suppression) diode designed for ESD and overvoltage transient protection. It can be used in a variety of applications including data lines, automotive electronics, and consumer electronics. It works by absorbing and dissipating high-voltage transients that would otherwise damage or destroy conventional electronics. It is capable of handling transients up to 15A or 3000V and has a response time of 1 nanosecond. This makes it an ideal choice for many applications where transient protection is needed.
