Description
This device has been 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
This component presents a very low gate
triggering current (I
consumption on printed circuit boards during the
firing phase.

A Trisil™ is not subject to ageing and provides
a fail safe mode in short circuit for better
protection.
Trisils are used to help equipment meet various
standards such as UL1950, IEC 950 / CSA
C22.2, UL1459 and FCC part68.
Trisils have UL94 V0 approved resin.
Trisils are UL497B approved (file: E136224).
