fig1. pulse waveform fig3.power derating application note elec trostatic discharge (esd) is a major cause of failure in electronic systems. transient voltage suppressors (tvs) are an ideal choice for esd protecti on. 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 offer the best choice for minimal le ad inductance. they serv e as parallel protection elements, connected between the signal line 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 ideal board evel protection of esd sensitive semiconductor components. the tiny sod523 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 againt esd. the lesd5z2.5t1g is leshan radio comp any, ltd. lesd5z2.5t1g series rev.o 3/6
