LCP1521DEE

Manufacturer Part Number
LCP1521DEE
Description
(LCP1521S/DEE) Programmable transient voltage suppressor
Manufacturer
STMicroelectronics

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]).
