MLCE40A TVS – Diodes Application Field and Working Principle

MLCE40A is a silicon diode which provides protection from destructive electrostatic discharges (ESD). This device consists of two internal protection diodes which are placed in parallel, forming the bidirectional protection. This diode is designed specifically for both free-wheeling diode replacement and for ESD protection in various types of communication systems.

Applications

MLCE40A diodes are mostly used in electronic systems and components which are exposed to air discharge or system failure due to electrostatic discharges. They provide protection from voltage spikes and over-voltage transients. As such, MLCE40A diodes are typically employed in various communication systems, such as Point-to-Point (PTP) radio, GSM/3G, ISDN, VoIP, Ethernet, ATM, WCDMA, CDMA, and SDH/SONET systems. Additionally, they can also be used for general purpose ESD protection, as well as voltage spike and over-voltage protection in automotive, avionic, and industrial environment applications.

Working Principle

In order to understand the principle of how MLCE40A diodes function, it is necessary to understand the phenomenon of electrostatic discharge (ESD). ESD is basically a phenomenon of transient current flow which occurs when electrons are released onto a surface from an unbalanced electrical charge. The current which is generated by the ESD is known as an electrostatic micro-discharge. MLCE40A diodes are specifically designed to protect sensitive components in communication systems from damage caused by ESD. The two internal protection diodes in the MLCE40A are placed in parallel to each other in such a way that the voltage across them will always be a maximum of 40 Volts. These diodes then work to neutralize the voltage of the ESD within a certain level so as to prevent it from damaging the sensitive components. In addition, the diodes protect the ESD voltage from propagating and discharging through the other components. MLCE40A diodes also have an internal capacitance which works to limit the current at the time of discharge. This helps to protect the system against over-current damage which could otherwise occur due to the large peak currents created by the ESD. Finally, the capacitance also helps to reduce the amount of energy contained in the ESD by dissipating it over the diodes.

Conclusion

In conclusion, the MLCE40A diodes are mainly used for ESD protection in various communication systems and components. These diodes work to provide protection from voltage spikes and over-voltage transients, as well as limiting the current at the time of discharge. Moreover, they also serve to reduce the amount of energy contained in the ESD by dissipating it over the diodes. All these features make the MLCE40A diodes an ideal choice for various ESD protection applications.
