ESDA14V2 数据手册 ( 数据表 ) - STMicroelectronics

DESCRIPTION
The ESDAxxL 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. < 20µA at VBR.
▪ 300 W PEAK PULSE POWER (8/20µs)

BenefitS
   High ESD protection level : up to 25 kV.
   High integration.
   Suitable for high density boards.
  
APPLICATIONS
   Where transient overvoltage protection in ESD
   sensitive equipment is required, such as :
      - 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.
