ASD (Application Specific Devices)
Features
Description
These devices have been especially designed
to protect 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
through the gate.
These components present a very low gate
triggering current (I
current 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 level of
protection. Trisils are used to ensure equipment
meets various standards such as UL60950,
IEC950 / CSA C22.2, UL1459 and FCC part 68.
Trisils have UL94 V0 approved resin (Trisils are
UL497B approved [file: E136224]).
