TVS (Transient voltage suppressor) diodes offer protection against damaging voltage transients that can be caused due to switching spikes and lightning strikes. The LCE20A-E3/73 is a unidirection TVS diode designed to protect electronic circuits from excessively high voltage transients. This device is specifically designed for applications that requires positive or unidirectional transient voltage protection and it comes in an isolated power package that offers superior surge protection.

The LCE20A-E3/73 is an axial leaded TVS diode that works on the principle of exceeding the Maximum Clamping Voltage (MCV). In this device, the MCV is 20A and the peak pulse current is 375A which is extremely suitable for high surge protection. The unique construction of the LCE20A-E3/73 involves a low profile, a wide operating temperature range and an improved failure mode that makes it ideal for high speed, low profile, automotive, industrial and telecom applications.

The main application of the LCE20A-E3/73 is to provide protection against low to medium level electrical transients. It can also be used to protect LAN equipment, telecommunication circuits, wiring harnesses, control systems and other sensitive electronic equipment from damage due to ESD events. In addition, this device has a low forward voltage drop which helps it to clamp the voltage quickly and effectively.

The working principle of the LCE20A-E3/73 is very simple. It consists of two very basic components – a zener diode and a voltage suppressor. When a transient voltage is applied to the device, it begins to conduct. The zener diode works by triggering a breakdown of the voltage, while the voltage suppressor works by preventing it from exceeding its maximum clamping voltage.

This prevents damage due to the electrical overstress, by clamping the voltage and limiting the current. The device has a 20A peak pulse current and a 375A peak pulse current which helps it to quickly dissipate excess energy and protect the circuit from damage.

The LCE20A-E3/73 is a capable and reliable device designed to provide robust protection against damaging voltage transients. Its wide operating temperature range, robust construction and low forward voltage drop make it ideal for a variety of applications. It is an affordable solution for electricians and engineers who require solid protection against surges and transients.
