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.
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 2 Unidirectional Transil functions
z Low leakage current: I_R max< 20 μA at VBR
z 3 00W peak pulse power(8/20μs)
z High ESD protection level: up to 25 kV
