ESDA5V3

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. ELECTROSTATIC DISCHARGE 300 WATTS 5.3/6.1/14.2/25 VOLTS 3 1 2 Features: * 2 Unidirectional Transil functions * Low leakage current: IR max< 20 A at VBR * 300W peak pulse power(8/20 s) * 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) SOT-23 Eqivalent Circuit Diagram: 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.
