TVS - Diodes, or Transient Voltage Suppressors, are semiconductor devices used to protect electronics against over-voltage or electric spikes. They are designed to reduce or eliminate voltage spikes in order to protect sensitive electronic components from damage caused by excessive voltages. One example of a TVS - Diode is the LCE18A, which is a high performance device that is designed to protect power lines, data lines, and equipment cables from over-voltage or electric spikes.

The LCE18A is an ESD protection diode specifically designed for automotive and industrial applications. It is a surface-mount device (SMD), which makes it ideal for tight spaces in electronic circuits. The device has a size of 2mm x 1.5mm and a height of 0.6mm, which makes it small enough to enable space-saving applications. It is also RoHS compliant, which ensures environmental safety.

The LCE18A is a dual-function diode that can be used as either a protection diode or a switching diode. When used as a protection diode, it provides a low-capacitance ESD protection diode. This helps reduce levels of ESD, or electrical noise, without adding noise to the signal path. It is suitable for high frequency applications such as data line protection, USB ports protection, and CAN bus protection.

When used as a switching diode, the LCE18A can be used as a signal ground diode or a signal switching diode. As a signal ground diode, it provides a low-impedance path for the short pulse of current which occurs when ESD pulses are delivered onto the device. As a signal switching diode, the device can be used to switch logic signals and provide reliable on/off control. It is suitable for applications such as automotive and industrial motor control, reverse battery protection, and CAN bus protection.

The device has a maximum working voltage of 18V and a maximum ESD withstand voltage of 20kV. It has a maximum operating temperature of 125°C and a maximum storage temperature of 150°C. The LCE18A also features a low leakage current, and it has a wide range of options in terms of polarity, pin configuration, and package size.

In summary, the LCE18A is a small, high performance, dual-function diode which is designed to protect power lines, data lines, and equipment cables from over-voltage or electric spikes. It is suitable for a wide range of applications, including data line protection, USB ports protection, and CAN bus protection. The device is RoHS compliant and features a low leakage current, making it an ideal choice for automotive and industrial applications.
