DUAL LINE PROGRAMMABLE TRANSIENT VOLTAGE

A.S.D.™

SUPPRESSOR FOR SLIC PROTECTION

FEATURES

s Dual line programmable transient voltage

suppressor

s Wide negative firing voltage range:

VMGL = -150 V max.

s Low dynamic switching voltages: VFP and VDGL

s Low gate triggering current: IGT = 5 mA max

s Peak pulse current: IPP = 15 A (10/1000 µs)

s Holding current: IH = 150 mA min

DESCRIPTION

This device has been especially designed to

protect 2 new high voltage, as well as classical

SLICs, against transient overvoltages.

Positive overvoltages are clamped by 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 cur-

rent consumption on printed circuit board during

the firing phase.

BENEFITS

Trisils are not subject to ageing and provide a fail

safe mode in short circuit for a better protection.

Trisils are used to help equipment to meet various

standards such as UL1950, IEC950 / CSA C22.2,

UL1459 and FCC part68. Trisils have UL94 V0

resin approved (Trisils are UL497B approved (file:

E136224)).
