Introduction

The SA28A-E3/73 is designed for use with personal electronic equipment, such as television, audio/video players, cameras, and other similar products. It is a specialized device that is designed to protect against transient performance (overvoltage) from either the equipment or surrounding environment. The SA28A-E3/73 is designed to provide high-performance protection from transient performance while minimizing the equipment\'s effects on the functionality of the protected equipment.

TVS-Diodes

TVS (transient voltage suppression) diodes, also known as transient suppressors, are diodes used to protect sensitive electronic components from transient overvoltages. Transient overvoltages are short-duration voltage levels that exceed the rated operating voltage of the component. They can be caused by static electricity, power supply surges, lightning, or any device that produces sudden voltage spikes.TVS diodes are designed to provide superior protection from these types of overvoltages. They are generally built using two-terminal Zener Diodes, which are semiconductor-based diodes that have a breakdown voltage at which conduction begins. When a voltage surge is applied, the TVS diode will conduct current at the breakdown voltage and release it to ground. This reduces the voltage on the sensitive components, thus protecting them from damage.

SA28A-E3/73 Application Field and Working Principle

The SA28A-E3/73 provides protection against transient overvoltage performance from both the equipment and the surrounding environment. It has a rated operating voltage of 15.6V and a maximum breakdown voltage of 21V. This TVS diode is designed to provide superior protection of equipment by clamping any voltage transient up to its maximum breakdown voltage.The SA28A-E3/73 is designed to protect the equipment by clamping high voltage transients that occur beyond its rated operating voltage. When a voltage transient occurs, the diode will conduct current to ground, protecting the surrounding equipment from potential damage. As such, the SA28A-E3/73 is an ideal choice for protecting sensitive electronics from transient overvoltage performance.

Conclusion

In conclusion, the SA28A-E3/73 is a specialized TVS diode designed for use with personal electronic equipment, such as television, audio/video players, cameras, and other similar products. It provides superior protection against transient performance (overvoltage) from either the equipment or surrounding environment. This TVS diode is designed to clamp any voltage transient up to its maximum breakdown voltage, thus protecting the sensitive electronics and helping to ensure their reliable performance.
