Dual Programmable Transient Voltage Suppressor(TVS)
S61089, S61089A & S61089B
Description
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.
Feature
u Dual line programmable transient voltage suppressor
u Wide negative firing voltage rage :
VMGL= -75V (S61089)
VMGL= -100V (S61089A)
VMGL= -155V (S61089B)
u Low dynamic switching voltages VFP and VDGL
u Low gate triggering current: IGT = 5mA max
u Peak pulse current: IPP = 30A (10/1000μs)
u Holding current: IH > 150mA
Benefits
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.
