Transient Voltage Suppressors for ESD Protection
ESDXXV92D-C Series
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 ESD9DXXCA 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.
