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 particularattention has beengiven to the internal wire bonding. The ”4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (Ldi/dt), especially for very fast transient overvoltages.
