ITAxxB1BIDIRECTIONAL TRANSIL™ ARRAY
FOR DATALINE PROTECTION
REV. 1
December 2004
MAIN APPLICATIONSDifferential data transmission lines protection,
such as : RS-232 RS-423 RS-422 RS-485
FEATURES High surge capability Transil array:
IPP = 40 A (8/20µs) Peak pulse power : 300 W (8/20µs) Up to 5 bidirectional Transil functions Low clamping factor (VCL / VBR ) at high current
level Low leakage current ESD protection up to 15kV
DESCRIPTIONTransil 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)

Note 1: For surges greater than the specified maximum value, the I/O will first present a short-circuit and after an open circuit caused by the wire melting.
Note 2: Between I/O pin and ground.
Note 3: Between two input pins at 0V Bias, F = 1 MHz.

ITAxxB1This monolithic Transil Array is based on 6 unidirectional Transils with a common cathode and can be con-
figurated to offer up to 5 bidirectional functions. This imposes a maximum differential voltage between 2
input pins (see table 4).
