DESCRIPTION
This device has been especially designed to
protect subscriber line cards against overvoltage.
Two diodes clamp positive overloads while
negative surges are suppressed by two protection
thyristors.
A particular attention has beengiven to the internal
wire bonding. The 鈥?-point鈥?configuration ensures
a reliable protection, eliminating overvoltages
introduced by the parasitic inductances of the
wiring (Ldi/dt), especially for very fast transient
overvoltages.
