MAP4KE68A

MAP4KE68A Application Field and Working Principle

MAP4KE68A is a type of TVS (Transient Voltage Suppressor) diodes. It is mainly used to protect sensitive equipment from voltage spikes and transients. It is designed to withstand extreme surges and prevent overvoltage conditions. Its reliable protection, low clamping voltage, and low dynamic impedance are some of its features.

This device is designed to limit the voltage across the device to a pre-defined value. It does this by redirecting excessive current away from the protected circuits. The device operates whenever the voltage on the anode terminal exceeds a certain value, called the breakdown or clamping voltage, allowing current to flow from the anode to the cathode. When the voltage across the device is within nominal limits, the current flow is blocked.

MAP4KE68A devices are mainly used in applications such as UPS, communications, home audio, and CCTV. They provide a reliable circuit protection for any device. They are also the ideal choice for over-voltage and electrostatic discharge (ESD) protection.

The MAP4KE68A device is made up of a junction diode with a fast-acting protection element. The junction diode is surrounded by a resistive network of two series-connected resistors, which control the clamping voltage of the device. The junction and the series resistors form the dynamical impedance of the device. The voltage drop across the series-connected resistors is needed to increase the dynamic impedance of the device, making it suitable for use in rapid-rising over-voltage and over-current conditions.

The MAP4KE68A is a robust device and is widely used for its reliable protection capabilities. It has low dynamic impedance which allows it to maintain its clamping voltage, even when the transient voltage is rising at a fast rate. It also has a low dynamic impedance which minimizes its impact on the protected system.

The MAP4KE68A is a bi-directional TVS diode, meaning it can be will handle current spikes and transients in either polarity. This feature makes the MAP4KE68A device an ideal choice for multiple applications. It is also an inexpensive and reliable way to protect any sensitive electronics from ESD.
