ITAxxB1
BIDIRECTIONAL TRANSIL™ ARRAY
ASD™
FOR DATALINE PROTECTION
MAIN APPLICATIONS
Differential data transmission lines protection,
such as :
■ RS-232
■ RS-423
■ RS-422
■ RS-485
FEATURES
■ High surge capability Transil array:
I_PP = 40 A (8/20µs)
■ Peak pulse power : 300 W (8/20µs)
■ Up to 5 bidirectional Transil functions
■ Low clamping factor (V_CL / V_BR) at high current
level
■ Low leakage current
■ ESD protection up to 15kV
DESCRIPTION
Transil diode arrays provide high overvoltage pro-
tection by clamping action. Their instantaneous re-
sponse to transient overvoltages makes them
particularly suited to protect voltage sensitive de-
vices such as MOS Technology and low voltage
supplied IC’s.
The ITA series combines high surge capability
against energetic pulses with high voltage per-
formance against ESD.
COMPLIES WITH THE FOLLOWING STANDARDS:
■ IEC61000-4-2 level 4:
15kV (air discharge)
8kV (contact discharge)
■ MIL STD 883E-Method 3015-7: class3
25kV HBM (Human Body Model)
