t(s) ^DESCRIPTION
c This device has been especially designed to
u protect subscriber line cards against overvoltage.
d _{Two diodes clamp positive overloads while}
ro negative surges are suppressed by two protection
P thyristors.
te ^{A particular attention has been given to the internal}
wire bonding. The “4-point” configuration ensures
le _{a reliable protection, eliminating overvoltages in-}
o _{troduced by the parasitic inductances of the wiring}
s _{(Ldi/dt), especially for very fast transient}
b _{overvoltages.}
