Transient voltage suppressors (TVS) are highly robust electronic components designed for suppressing transient voltage events, such as those caused by electrostatic discharge (ESD), lightning strikes, and other fast voltage transients, and protecting sensitive electronic devices or circuits from associated damages. The MXLCE15A is an advanced device designed to protect against overvoltages and overcurrents in a wide variety of applications.

MXLCE15A is a high-performance surface mount TVS diode specifically designed to protect semiconductor devices against overvoltages and overcurrents caused by external static fields, transient voltages due to electrostatic discharge (ESD) or lightning strikes. The device is specifically suited for lower voltage, higher density applications such as Ethernet, USB, VGA, DVI, and more. It is available in a robust SC75 round SMA package, making it perfect for space-limited applications.

Application field

MXLCE15A is an ideal solution for protecting I/O interfaces in applications such as servers, computers, gaming consoles, and telecommunications systems. It is also suitable for automotive, medical, and consumer electronics applications which require extremely fast response time. The device is also ideal for industrial and instrumentation systems that use high speed communication protocols such as CAN, SPI, and I2C.

Working principle

The device is constructed with a positive temperature coefficient (PTC) nonlinear resistance element and built-in capacitance. The PTC element limits the current flow through the device during an ESD event by increasing the resistance, thus preventing damage to the protected circuit. The integrated capacitance helps reduce the voltage overshoot produced by the ESD event, allowing for optimal voltage protection.

The MXLCE15A is also designed with a dual-point breakdown mechanism, which means that when the device is subjected to an ESD pulse, the first breakdown point is triggered, thus allowing for dynamic clamping of the voltage. This allows for faster protection than is achievable with a single-point breakdown mechanism. In addition, the device also features a highly sensitive high frequency response, making it ideal for applications with high speed signals.

In summary, the MXLCE15A transient voltage suppressor is a high performance device designed to protect semiconductor devices from transient overvoltage and overcurrent events caused by ESD, lightning strikes, and other external static fields. It is specifically designed for lower voltage, higher density applications, and is available in a robust SC75 round SMA package, making it ideal for space-limited applications. The device is also designed with a dual-point breakdown mechanism and a highly sensitive high frequency response, making it suitable for applications with high speed signals.
