DUAL ASYMETRICAL TRANSIENT

SUPPRESSOR

PRODUCT PREVIEW

SAN T A ANA DIV I S I ON

DESCRIPTION

This Thyristor Surge Suppressor 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.

Particular attention 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.
