Introduction to TVS Diodes

Transient Voltate Suppression Diodes or (TVS) diodes are semiconductor devices which are used to protect sensitive electronic equipment from voltage spikes. They provide a bidirectional solution, and are a cost-effective and simple solution to protect against voltage transients. These devices differ from traditional zener diodes in that they are not limited to only one voltage; They have a greater power and current handling capability and offer a short response time. Depending on the application, they can be constructed with different capacities, such as low capacitance, low leakage current, fast response time, low reverse leakage current and more.

SA5.0CA-E3/73 Application Field and Working Principle

The SA5.0CA-E3/73 is a LED type TVS diode designed for use in industrial UV exposure applications. It is made of a high-temperature synthetic material with low capacitance and low leakage current. The device also offers fast response time in order to provide protection from voltage transients.

The diode has a reverse breakdown voltage of 5V and a maximum peak pulse current of 73A at 8/20 microsecond with a maximum clamping voltage of 7.8V. This TVS diode protects the circuit from induced voltages up to 5V and clamping voltages up to 7.8V.

The diode operates in a simple way, when a voltage transient occurs, the forward voltage of the diode starts to increase, and the current passes through it. Then the voltage will drop to the peak clamping voltage of the device and the current will start to decrease. This dissipates the transient energy and protects the device from the transient.

Conclusion

The SA5.0CA-E3/73 is an LED type TVS diode with a reverse breakdown voltage of 5V and a maximum peak pulse current of 73A. It offers protection from voltage transients in industrial UV exposure applications, providing a simple and cost-effective solution for circuit protection. This diode operates by dissipating the transient energy when a voltage transient occurs, thus protecting the device.
