TVS (Transient Voltage Suppressor) diodes are essential components in the majority of circuits for protection against electrodynamic forces, such as indirect lightning strikes and EMP (electromagnetic pulses) devices. The LCE15-E3/73, a high-voltage transient voltage suppressor diode, is one of the most common TVS diodes when it comes to circuit protection.

The LCE15-E3/73 is a solid-state component, meaning its operation is electromechanical instead of electrical. It is design to clip momentary voltage surges beyond the permissible level, thus protecting the circuit from potential damages or destruction. It is available in a wide range of voltage ratings, ranging from 50 to 1500 volts. The typical breakover voltage (Vbr) is between 12 to 24 volts.

The working principle of the LCE15-E3/73 is quite simple: it has two metal plates separated by a thin film of insulating material. When a voltage surge occurs, the insulating material is overcome by the electrical force of the voltage, causing the two plates to come into contact and allowing a potential current to flow. This current will then be dissipated through the diode, avoiding any further damage.

The LCE15-E3/73 is used in a variety of electronic systems as a primary surge protection device for both AC and DC circuits. It is typically applied in telecommunications, industrial control systems, home appliances, consumer electronics, automotive and other high complexity electronic systems.

The diode is installed in series with the protected load, where it will absorb any transient surge occurring. The circuit must be designed to ensure that the voltage rating of the LCE15-E3/73 is not exceeded. To ensure proper operation, the total surge current rating (Ipp) must also be considered. The typical surge current rating of the LCE15-E3/73 is 20A peak pulse current, with a clamping voltage of 18V, at circuit board level.

The LCE15-E3/73 can be a great choice for circuit protection in a wide range of applications. It is specifically designed to protect sensitive components or circuits from excessive transient overvoltages, and can effectively reduce the destruction that such voltage surges can cause. If you need a solid-state diode for transient voltage protection, the LCE15-E3/73 is certainly a good choice.
