5/310 s tr = 5s tp = 310 s
2/10 s tr = 2s tp = 10 s

This Thyristor Surge Suppressor device TCP120A 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.

Particular attention TCP120A has been given 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.
