TRANSIENT VOLTAGE SUPPRESSORS FOR ESD PROTECTION
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 SESD9DXXC
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.
