transient voltage suppressors for esd protection general description the is a transient voltage suppressor designed to protect components which are connected to data and transmission lines against esd. it clamps the voltage just above the logic level supply for positive transients, and to a diode drop below ground for negative transients. applications z computers z printers z communication systems features z unidirectional transil functions z low leakage current: i r max< 20 a at v rm z 300w peak pulse power(8/20 s) absolute ratings (t amb =25 c ) symbol parameter value units p pp peak pulse power (t p = 8/20 s) 300 w t l maximum lead temperature for soldering during 10s 260 c t stg storage temperature range -55 to +150 c t op operating temperature range -40 to +125 c t j maximum junction temperature 150 c v pp electrostatic discharge iec61000-4-2 air discharge iec61000-4-2 contact discharge 15 8 kv sot? 23 s-LGSOT08LT1G 1 3 2 leshan radio company, ltd. z transient protection for data lines as per z we declare that the material of product compliance with rohs requirements. device package shipping ordering information iec61000-4-2(esd) 15kv(air) 8kv(contact) iec61000-4-5(lightning) see i ppm below LGSOT08LT1G rev.o 1/5 LGSOT08LT1G LGSOT08LT1G sot23 3000/tape & reel s-LGSOT08LT1G z s- prefix for automotive and other applications requiring unique site and control change requirements; aec-q101 qualified and ppap capable.

application note electrostatic 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 is the ideal board evel protection of esd sensitive semiconductor components. the tiny sot23 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. leshan radio company, ltd.
