SMP80MC
TRISIL™ FOR TELECOM EQUIPMENT PROTECTION
FEATURES
■ Bidirectional crowbar protection
■ Voltage: range from 120V to 270V
■ Low V_BO / V_R ratio
■ Micro capacitance equal to 12pF @ 50V
■ Low leakage current : I_R = 2µA max
■ Holding current: I_H = 150 mA min
■ Repetitive peak pulse current :
■ I_PP = 80 A (10/1000µs)
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 protec-
tion of high debit rate communication equipment
on CPE side. Its micro capacitance avoids any dis-
tortion 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.
