Electrostatic discharge (ESD) is a major cause of failure in electronic systems. Transient Voltage Suppressors (TVS) are an ideal choice for ESD prot ection. 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 mi nimal 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 SESD3ZxxC is the ideal board evel protection of ESD sensitive semiconductor components. The tiny SOD-323 package allows design flexibilit y in the design of high density boards where the space saving is at a premium. This enables to shorten the routing and cont ributes to hardening against ESD.
