WILLAS
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 SESD3Z5C is the ideal board evel protection of ESD sensitive semiconductor components.
The tiny SOD-323 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.
