Dual Programmable Transient Voltage Suppressor(TVS)
S61089, S61089A & S61089B
Description
SOP-8
This device has been especially designed to protect subscriber line
card interfaces (SLIC) against transient over-voltages. Positive
overloads are clipped with 2 diodes. Negative surges are suppressed
by 2 thyristors, their breakdown voltage being referenced to-VBAT
through the gate. This component presents a very low gate triggering
current (IGT) in order to reduce the current consumption on printed
circuit board during the firing phase. A particular attention has been
given to the internal wire bonding. The configuration ensures reliable
protection, eliminating the overvoltage introduced by the parasitic
inductances of the wiring (Ldi/dt), especially for very fast transients.

Benefits
Marking
The devices are not subject to ageing and provide a fail safe mode in
short circuit for a better protection. They are used to help equipment
to meet various standards such as UL1950, IEC / CSA C22.2,
UL1459 and FCC part68.
