BIDIRECTIONAL TRANSILTM ARRAY FOR DATALINE PROTECTION
Application Specific Discretes A.S.D.TM
APPLICATIONS
Differential data transmission lines protection : - RS-232 - RS-423 - RS-422 - RS-485
FEATURES HIGH SURGE CAPABILITY TRANSIL ARRAY IPP = 40 A (8/20s) PEAK PULSE POWER : 300 W (8/20s) UP TO 5 BIDIRECTIONAL TRANSIL FUNCTIONS LOW CLAMPING FACTOR (VCL / VBR) AT HIGH CURRENT LEVEL LOW LEAKAGE CURRENT ESD PROTECTION UP TO 15kV SO8
FUNCTIONAL DIAGRAM
DESCRIPTION Transil diode arrays provide high overvoltage protectionby clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC's. The ITA series allies high surge capability against energetic pulses with high voltage performance against ESD.
