MXLPLAD15KP78A Application Field and Working Principle

TVS - Diodes offer transient protection of various electronic systems from transients caused by electrostatic discharge (ESD) and other electrical disturbances. The MXLPLAD15KP78A is a high-performance, ultra-low capacitance, bi-directional ESD protection diode for telecom and other I/O interfaces. Its low capacitance design combined with reliable ESD protection ensures proper signal integrity performance.

Application Field

MXLPLAD15KP78A is a bi-directional TVS diode suitable for general purpose ESD protection on sensitive data and telecom lines. It has the capacity to divert high voltage transients on a low capacitance line and is capable of supporting higher power applications. For example, it can be used on USB, FireWire, HDMI, HD-SDI, Fibre Channel, IEEE 1394, and similar interfaces.

MXLPLAD15KP78A is ideal for applications where low capacitance is desired, and it can be used in low speed and mixed signal applications such as microcontrollers, memory, clocks, and audio. It can also be utilized in I/O protection for laptops and tablets, and in server/communication applications such as security cameras and industrial controls.

Working Principle

MXLPLAD15KP78A acts as a filter to protect circuits from transients caused by external events such as ESD, lighting, etc. It contains a low capacitance diode bridge that is clamped to ground when a high voltage transient appears. When the transient is removed, the bridge reverts back to its original state.

The MXLPLAD15KP78A also provides protection against reverse power or polarity reversal, eliminating the need for a Dual Exponential Resistance Diode (DERR). When the polarity is reversed, the diode bridge is clamped to ground, preventing current from passing through the line.

The MXLPLAD15KP78A has a low capacitance design, allowing it to be used in a wide range of high speed, low capacitance applications. The low capacitance design combined with reliable ESD protection ensures signal integrity and reduces system power consumption.
