MP5KE120AE3

TVS - Diodes

The MP5KE120AE3 is a Transient Voltage Suppressor diode (TVS) designed to provide circuit protection from damaging over voltage conditions. This diode features a very low let-through voltage and provides good clamping performance without affecting system performance. TVS diode technology is well-suited for systems that have a high level of sensitivity.

Application Field

The MP5KE120AE3 is a low capacitance, low voltage diode designed for use in portable electronics, communication equipment, and computer systems. This type of diode is designed to protect against over voltage transients in sensitive circuits and systems. It can be used to protect against lightning surge, ESD (electrostatic discharge), and over voltage transients.

Working Principle

The MP5KE120AE3 works on the principle of crowbar protection. This means that when an over voltage transient is detected, the diode switches from being off to being on, and this causes a “crowbar” effect, which clamps the over voltage and prevents it from entering the system. In addition to providing protection from over voltage transients, the MP5KE120AE3 also provides EMI/RFI protection. This diode is designed to have a very low capacitive and inductive coupling, so it helps to reduce electromagnetic interference.

Conclusion

The MP5KE120AE3 is a low capacitance, low voltage TVS diode that provides protection from over voltage transients and EMI/RFI radiation. It works on the principle of crowbar protection and can be used in a variety of portable electronics, communication equipment, and computer systems. This type of diode is relatively easy to install and provides a high level of reliability when used in sensitive circuits and systems.
