ESDAXX Datasheet, PDF (1/3 Pages) Weitron Technology – Dual transil arr ay for ESD protection

ESDAxx Series
Dual transil array for ESD protection
P b Lead(Pb)-Free
Description:
* The ESDAxx 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.
Features:
* 2 Unidirectional Transil functions
* Low leakage current: IR max< 20 μA at VBR
* 300W peak pulse power(8/20μs)
* High ESD protection level: up to 25 kV
* Complies with the following standards:
IEC61000-4-2 Level 4
MIL STD 883c - Method 3015-6 Class 3(Human Body Model)
Application:
* Computers
* Printers
* Communication systems
* It is particulary recommended for the RS232 I/O port protection where
the line interface withstands only with 2kV ESD surges.
Mechanical Data:
* Case : Molded Epoxy
* Marking : Marking Code
* Weight : 0.008 grams(approx)
