Dual line programmable transient voltage suppressor for

SLIC protection

Features

■ Dual line programmable transient voltage

suppressor

■ Wide negative firing voltage range:

■ V_MGL= -150 V max.

■ Low dynamic switching voltages: V_FPand

V_DGL

■ Low gate triggering current: I_GT= 5 mA max

■ Peak pulse current: I_PP= 20 A (10/1000 µs)

■ Holding current: I_H= 150 mA min

SO-8

Description

Functional diagram

This device has been especially designed to

protect 2 new high voltage, as well as classical

SLICs, against transient overvoltages.

TIP 1

RING 1

Positive overvoltages are clamped by 2 diodes.

Negative surges are suppressed by 2 thyristors,

their breakdown voltage being referenced to -V_BAT

through the gate.

GND

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.

Benefits

TIP 2

RING 2

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)).
