The MXLP4KE43A is a TVS diode designed to protect sensitive electronic components from over-voltage caused by lightning, high-energy transients, or induced power surges. The device can also be employed for the transient protection of IT and telecoms equipment, such as set-top boxes and TVs.

The MXLP4KE43A is a single-line flanged body device capable of protecting two data lines in one device. The MXLP4KE43A is available in three power versions, with a unidirectional or bidirectional form. It includes an integrated electrostatic discharge (ESD) protection diode, creating an effective multi-element solution.

As a TVS diode, the MXLP4KE43A works by providing a highly efficient over-voltage protection. When a voltage exceeding the diode\'s rated Clamping Voltage (VC) is applied, the diode conducts all of the current. Additionally, when a transient amplitude exceeds the diode\'s rated Breakdown Voltage (VBR), the diode clamps the voltage and dissipates the energy. The clamping voltage (VC) is determined by the device\'s ionization or avalanche breakdown, depending on the characteristics of the over-voltage.

The flanged body design of the MXLP4KE43A makes it suitable for a variety of applications. The device is housed in a small package, making it suitable for use in space-constrained applications, such as portable and mobile devices, which are especially prone to damage from over-voltage transients. Additionally, its flanged body design allows for easy connection and mounting.

The MXLP4KE43A provides over-voltage protection for sensitive electronic components, such as TVs and set-top boxes. It features an integrated ESD protection diode and a flanged body design, which makes it suitable for space-constrained applications. Its wide operating voltage range and high clamping voltage make it an ideal solution for protection against high-frequency pulses and transients, which can often lead to damage or destruction of sensitive electronic devices.
