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 LESD3Z5.0CMT1G is the ideal boar
d 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.
