FEATURES

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,

through the gate.

This component presents a very low gate

rent consumption on printed circuit board during

the firing phase.

FUNCTIONAL DIAGRAM

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)).
