fig2.power derating application note 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 su ch that damage to the protected semiconductor is prevented. surface mount tvs offers the bes t choice for minimal lead induct ance. 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 d evel 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. lesd5d5.0ct1g leshan radio company, ltd. current to ground. the lesd5d5.0ct1g is the ideal boar rev.o 3/6
