SMP80MC
TRISIL™ for telecom equipment protection
Features
■ Bidirectional crowbar protection
www.DataSheet4U■.comVoltage: range from 120 V to 320 V
■ Low VBO / VR ratio
■ Micro capacitance equal to 12 pF @ 50 V
■ Low leakage current : IR = 2 µA max
■ Holding current: IH = 150 mA min
■ Repetitive peak pulse current :
■ IPP = 80 A (10/1000 µs)
Main applications
Any sensitive equipment requiring protection
against lightning strikes and power crossing:
■ Terminals (phone, fax, modem...) and central
office equipment
Description
The SMP80MC is a series of micro capacitance
transient surge arrestors designed for the
protection of high debit rate communication
equipment on CPE side. Its micro capacitance
avoids any distortion of the signal and is
compatible with digital transmission like ADSL2
and ADSL2+.
Benefits
Trisils are not subject to ageing and provide a fail
safe mode in short circuit for a better protection.
They are used to help equipment to meet main
standards such as UL1950, IEC950 / CSA C22.2
and UL1459. They have UL94 V0 approved resin.
SMB package is JEDEC registered (DO-214AA).
Trisils comply with the following standards GR-
1089 Core, ITU-T-K20/K21, VDE0433, VDE0878,
IEC61000-4-5 and FCC part 68.
