SMF7V0A-HE3-08 Circuit Protection

SMF7V0A-HE3-08 is a Transient Voltage Suppression (TVS) diode. It functions as a protective device that can guard against transient voltages or electrical spikes from reaching sensitive equipment. This type of diode acts as a shield and endures electrical stress before breaking down to protect the sensitive circuitry inside the device. Using TVS diodes can help extend product life cycles and improve performance.

Application Field

SMF7V0A-HE3-08 TVS diodes are represented by a bi-directional symbol – a box above two lines – and are typically used for the protection of sensitive circuits from transients such as electrostatic discharge, cable discharge, inductive spikes, and other surges. SMF7V0A-HE3-08 diodes are specifically designed for low voltage, high-speed circuits.

Common applications for SMF7V0A-HE3-08 diodes include computer and communication equipment, mobile phones, automotive systems, industrial and office appliances, consumer electronics, and more. TVS diodes are an effective solution for protecting sensitive components from transient voltages.

Working Principle

The principle behind the operation of SMF7V0A-HE3-08 diodes is simple. They act as a bridge between the source of the voltage spike or surge and the sensitive components in the application. When an electrical spike is detected by the diode, the diode quickly clamps and absorbs the excess voltage while allowing the original voltage to stay intact. In technical terms, this is known as "avalanche breakdown" - an effect that occurs when a diode is subjected to an abrupt increase in voltage, which causes a large increase in current.

The SMF7V0A-HE3-08 diode is rated for a range of voltage strengths depending on the specific application. If the voltage spike exceeds the breakdown voltage, the diode will experience avalanche breakdown, meaning it will break down and absorb the energy from the transient electrical shock. The avalanche breakdown helps protect the sensitive components in the device from being damaged by the transient voltage.

Conclusion

SMF7V0A-HE3-08 diodes are a great solution for protecting sensitive components and circuits from transient electric shocks. By absorbing the voltages of the transient shock, the diode eliminates the risk of damage to the components in the system. TVS diodes are versatile, and can be used for a wide range of applications, from consumer electronics to industrial and automotive systems.
