Transient voltage suppression (TVS) is the technology used for voltage protection of various devices and circuits in the electrical system. It is designed to help protect sensitive electronic components from high voltages which may cause damage. The MXL15KP110CA is a TVS diode that is specifically designed for storage, battery and antenna protection. It is a mobile diodes product which is offered in a SOT-23 package. The TVS diodes, such as the MXL15KP110CA, are designed to provide protection against electric surge and spikes, and to ensure safety and reliable operation in the system.

MXL15KP110CA Application Field

The MXL15KP110CA can be used in various applications such as mobile phones, tablet computers, GPS units, TVs, digital audio-video players, and automotive applications, as well as in industrial equipment. It provides improved electrostatic discharge (ESD) protection, surge handling capability, and low clamping voltage. It offers an optimised combination of low leakage for low supply current, low stray inductance, for optimal protection efficiency, and superior surge protection, to ensure not only reliability but also long service life.

The MXL15KP110CA is designed to protect sensitive components in smartphone, tablet and other portable applications from damage due to ESD, which typically occurs when the device is recharged or connected to another device. The MXL15KP110CA can also protect automotive and industrial applications from overvoltage and short circuit transients caused by electrical surges from the AC-DC and DC sources.

Working Principle of MXL15KP110CA

The MXL15KP110CA is a bidirectional TVS diode that automates the protection of sensitive electrostatic discharge sensitive (ESDS) circuits against ESD. The device consists of an array of avalanche diodes and an integrated high voltage protection circuit. It absorbs the excess energy from ESD and transient events, thereby preventing damage to the system and device. The working principle of the MXL15KP110CA is based on the avalanche breakdown mechanism.

Avalanche breakdown occurs when an avalanche diode is exposed to voltages higher than the breakdown voltage. During this process, the electron-hole pairs (generated by the impact ionization) in the intrinsic region of the avalanche diode increase very rapidly. The generated electric field in the diode drives the electrons in the cavity drift region, leading to current flow. This phenomenon is called avalanche breakdown.

The MXL15KP110CA acts as an electrical transducer: it dissipates excessive transient energy as heat as soon as it is present and produces a voltage which is able to absorb transient energy such that the overvoltage in the power supply of the system is limited. Thus, these diodes enable electrical systems to survive high-voltage conditions without damage.

Conclusion

The MXL15KP110CA is a TVS diode for mobile phones, tablet computers, TVs, digital audio-video players, automotive applications, and industrial equipment, designed to protect sensitive components from ESD, overvoltage, and short-circuit transients. It consists of an array of avalanche diodes connected in series with an integrated high voltage protection circuit. It uses the avalanche breakdown mechanism to absorb transient energy whereby the voltage is kept within limits to ensure reliability and long service life for the system.
