Application Note

Electrostatic discharge (ESD) is a major cause of failure in electronic systems. Transient Voltage

Suppressors (TVS) are an ideal choice for ESD protection. They are capable of clamping the incoming transient

Surface mount TVS offers the best choice for minimal lead inductance. They serve as parallel protection

elements, connected between the signal lines to ground. As the transient rises above the operating voltage of

the device, the TVS becomes a low impedance path diverting the transient current to ground. The SESD9D5C

is the ideal board evel protection of ESD sensitive semiconductor components.

The tiny SOD-923 package allows design flexibility in the design of high density boards where the space

saving is at a premium. This enables to shorten the routing and contributes to hardening against ESD
