FUNCTIONAL DIAGRAM  
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.

This monolithic Transil Array is based on 6  
unidirectional Transils with a common cathode and  
can be configurated to offer up to 5 bidirectional  
functions. This imposes a maximum differential  
voltage between 2 input pins (see opposite table).  
Typical application : RS232 junction.
