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 to a low enough level such
that damage to the protected semiconductor is prevented. 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 ESD9DXXC Series 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.
