MP4KE15A

TVS diodes are electrical overshoot protection devices used in electronics to protect sensitive electronic components from voltage surges caused by electrostatic discharge (ESD), lightning, other power surges, and inductive switching. The MP4KE series of overvoltage protection components from ON Semiconductor are designed to safeguard your printed circuit boards from damages due to overvoltage transients, and the MP4KE15A is a popular type of TVS diode in this series.

The MP4KE15A is a low-clamp, low-capacity unidirectional device that supports up to 15A reverse surge current. It is constructed with a surge-rated resistor to limit current and a voltage stake to dissipate excess energy. To understand the working principle of the MP4KE15A, we need to first understand what happens when a surge occurs. When a surge exceeds the voltage during normal operating conditions, the surge current will flow through the fuse, which triggers the diode and limits the current to a safe level. The voltage stake dissipates the excess energy instead of allowing current to flow into other components.

The MP4KE15A has a wide range of applications in different electronic circuits. It is particularly popular for protecting consumer electronics, such as mobile phones and laptops, against electrical surges. It is also often used in industrial electronic control circuits, such as those found in factory automation applications, to help protect machines from damaging voltage transients. The MP4KE15A is also frequently used in automotive electronic control units to protect circuits from overvoltage transients caused by EMI and ESD. In addition, the MP4KE15A is commonly used in telecommunication systems, home appliances, and power supply designs.

The MP4KE15A is an efficient and reliable overvoltage protection device that can help safeguard electronic components against damaging voltage spikes and surges. With its wide range of applications, the MP4KE15A is an excellent choice for protecting sensitive electronic components against power surges. It is also easy to install and requires minimal maintenance.
