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 line and 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 esd5zxx is the ideal board level protection of esd sensitive semiconductor components. the tiny sod-523 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. figure 4 : esd 5z xx protection against esd esd sensitive device gnd esd 5z xx (1connection to gnd for esd 5z xx ) i/ o lines esd5zxx series 3 of 4 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification
