LESDA5V3LT1G

www.DataSheet4U.com LESHAN RADIO COMPANY, LTD. Dual transil array for ESD protection General Description The LESDAxxxLT1G 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 bidirectionnal suppressor by connecting only pin1 and 2. LESDAXXXLT1G 3 1 2 SOT– 23 Applications z Computers z Printers z Communication systems It is particulary recommended for the RS232 I/O port protection where the line interface withstands only with 2kV ESD surges. Features z z z z 2 Unidirectional Transil functions Low leakage current: IR max< 20 μA at VBR 3 00W peak pulse power(8/20μs) High ESD protection level: up to 25 kV Benefits z z z High ESD protection level up to 25 kV.
