Benefits
■
Trisils are not subject to ageing and provide a
fail safe mode in short circuit for better
protection.
Helps equipment meet main standards such as
UL60950, IEC 950 / CSA C22.2 and UL1459.
Epoxy meets UL94, V0.
Package is JEDEC registered (DO-214AA).

Description
The SMP80MC is a series of micro capacitance
transient surge arrestors designed for the
protection of high debit rate communication
equipment. Its micro capacitance avoids any
distortion of the signal and is compatible with
digital transmission like ADSL2 and ADSL2+.
Complies with the following standards
