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,
their breakdown voltage being referenced to -V
BAT
through the gate.
This
component
presents
triggering current (I

) in order to reduce the cur-
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)).
