SA26A-E3/73 Circuit Protection

TVS diodes, which are also known as Transient Voltage Suppressors, are a type of power semiconductor that protect other vulnerable components from sudden voltage changes. The SA26A-E3/73 is an example of such a device, with many applications across various industries. This article provides an overview of the SA26A-E3/73 application field and working principle.

The SA26A-E3/73 is a dual bi-directional TVS diode. It is designed to provide ESD, EFT, and surge protection of data and signal lines. Some of the key features of this device include a peak pulse power rating of 400 Watts, a 5V to 36V working voltage range, and a 7.2V breakover voltage. Common applications for the SA26A-E3/73 include IT and communication equipment, medical devices, industrial power systems, electronic appliances, and automotive systems.

The SA26A-E3/73 works by providing a low current level that diverts high voltage transients away from the protected components. During normal operation, the TVS diode acts as an open circuit allowing no current to pass through. When a voltage transient is detected, the diode quickly switches to a low resistance state, allowing the current to flow away from the protected components. This helps to protect the components from damage due to voltage spikes. The diode then switches back to its open circuit state, thus restoring the flow of normal current.
