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-V_BAT

through the gate. This component presents a very low gate triggering

current (I_GT) 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

Functional Diagram

Dual line programmable transient voltage suppressor

Wide negative firing voltage rage :

V_MGL= -75V (S61089)

V_MGL= -100V (S61089A)

V_MGL= -155V (S61089B)

Low dynamic switching voltages V_FPand V_DGL

Low gate triggering current: I_GT= 5mA max

Peak pulse current: I_PP= 30A (10/1000μs)

Holding current: I_H> 150mA

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.
