dual transient voltage suppr essors array for esd protection general description the l gsot05clt1g is a dual monolithic 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. it can also work as bidirectional suppressor by connecting only pin1 and 2. applications z computers z printers z communication systems features z 2 unidirectional transil functions z r max< 20 a at v rm z 300w peak pulse power(8/20 s) z transient protection for data lines as per iec61000-4-2(esd) 15kv(air) 8kv(contact) iec61000-4-5(lightning) see i ppm below 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 lgsot05clt1g 1 3 2 leshan radio company, ltd. ordering information low leakage current: i device marking shipping lgsot05clt1g 05c 3000/tape & reel rev.o 1/5 ?aec q101 qualified and ppap capable z aec q101 qualified and ppap capable z

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 arrays offer the best choice for minimal lead inductance. they serve as parallel protection elements, connected between the signal line to ground. as the transient rises above the operating voltage of the device, the tvs array becomes a low impedance path diverting the transient current to ground. the array 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. lgsot05clt1g lgsot05clt1g rev.o 4/5
