Working Principles

The SMF22A-HE3-08 operates by diverting excess current away from sensitive components when a transient voltage spike occurs. It achieves this through the use of its diode-based design, which rapidly conducts when the voltage exceeds the breakdown voltage, effectively clamping the voltage to a safe level.

Detailed Application Field Plans

This voltage suppressor diode is commonly used in electronic circuits to protect sensitive components from voltage transients caused by events such as lightning strikes, ESD (electrostatic discharge), or inductive load switching. It finds applications in various industries including telecommunications, automotive, industrial electronics, and consumer electronics.
