SA10C-E3/73

TVS diodes are semiconductor devices which are designed to protect sensitive microelectronic components from transient over-voltage conditions. The SA10C-E3/73 is one of the most commonly used diodes for this purpose. This article looks at the application field and working principle of the SA10C-E3/73.

Application Field

The SA10C-E3/73 is primarily used for protecting from transients. It is relatively common to find these devices in power circuits, data lines, high voltage cables, signal lines, and similar. Oftentimes, these devices are used in conjunction with other protection components, such as varistors, which are able to provide additional protection against common and normal mode transient events.

The SA10C-E3/73 is most helpful for applications that are susceptible to transient over-voltages generated by static discharges, switching, or power arcing. It is often utilised in computer systems, industrial control systems, and automotive electronics.

Working Principle

The purpose of a TVS diode like the SA10C-E3/73 is to provide a low-impedance connection between the signal and ground. This connection is crucial for protecting microelectronic components from transient over-voltage conditions. It works by limiting the current that can pass through the diode to a safe level.

When a transient event occurs, the diode will draw a large amount of current and begin to conduct, allowing a large surge of current to pass between the two terminals. This surge of current will then be safely diverted away from the microelectronic components, thereby protecting them from the over-voltage conditions.

When the transient event has ended, the diode will return to its non-conductive state, allowing normal operation to resume. The TVS diode is able to do this by having a high surge rating which allows it to absorb a large amount of energy, as well as a fast response time so that it can react quickly to the transient events.

Conclusion

The SA10C-E3/73 is a popular TVS diode which is designed to protect sensitive microelectronic components from transient over-voltage conditions. The application field for this device includes power circuits, data lines, high voltage cables, and signal lines. It works by providing a low-impedance connection between the signal and ground, which limits the current that can pass through the diode to a safe level. By having a high surge rating and a fast response time, it ensures that the microelectronic components will be sufficiently protected.
