MP4KE100AE3 Datasheet/PDFTransient Voltage Suppressors (TVSs) have been widely used in power system protection owing to their superior surge absorbing capabilities. They are available in discrete form as well as several integration designs. The MP4KE100AE3 is a typical example of a discrete TVS integrated circuit. This article explains its application field and working principle.
The MP4KE100AE3 is suitable for a wide variety of applications including telecommunications systems, consumer electronic systems, PC motherboards, solid-state drive designs, portable electronic devices, automotive systems, and industrial control systems. Its ultra-low capacitance ensures unbeatable over-voltage protection in high-speed and data-sensitive electronic devices. It provides ESD protection for data line protection and other vulnerable components in the system.
The working principle of the MP4KE100AE3 is based on its semiconductor structure. It consists of a series of vertical PN junction diodes connected in parallel to reduce the capacitance. The diodes are then connected to two opposed electrode contacts, the anode and the cathode. Under normal operating conditions, the diode junction behaves like a resistor, allowing current to flow in one direction only. However, when a transient voltage spike is applied, the diode junction behaves like a short circuit, allowing current to flow in both directions. This diverts the voltage spikes away from the protected circuits they are connected to.
In order to maximize the ESD protection of the MP4KE100AE3, it is recommended to use external capacitors connected in parallel to the diode. This reduces the capacitance of the diode junction, allowing for more efficient voltage spike absorption. The device operates over a wide voltage range from 5V to 36V and is capable of withstanding voltages of up to 28V. The maximum surge current rating is 28A.
The MP4KE100AE3 is built on a state-of-the-art thick film technology, offering superior reliability even under extreme temperature and humidity conditions. It is offered in an SOD-323UF package, making it easy to mount and safer to handle during installation. The device is RoHS compliant and 100% lead-free.
In conclusion, the MP4KE100AE3 is a state-of-the-art TVS diode designed to provide superior ESD protection in a variety of electronic systems. Its series of vertical PN junction diodes, a wide voltage range, and its ultra-low capacitance make it the perfect choice for applications that require reliable surge absorption. Its SOD-323UF size and RoHS compliance make it easy to handle and safer to operate.
