ASD™
TRANSIL™ ARRAY
FOR DATALINE PROTECTION
MAIN APPLICATIONS
Data transmission lines protection, such as :
■
■
Unipolar signal up to 5.5 V
Bipolar signal in the ± 2.5 V range
FEATURES
■ High surge capability Transil array:
IPP = 40 A (8/20µs)
■
■
■
■
■
Peak pulse power : 300 W (8/20µs)
Up to 6 bidirectional Transil functions
Low clamping factor (VCL / VBR) at high current
level
Low leakage current
ESD protection up to 15kV
DESCRIPTION
Transil diode arrays provide high overvoltage protection by 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.
