® SMP80MC-270
TELECOM EQUIPMENT PROTECTION: TRISIL™
FEATURES
s Bidirectional crowbar protection
s Voltage: 270V
s Low VBO / VR ratio
s Micro capacitance 15pF typ @ 50V
s Low leakage current : IR = 2µA max
s Holding current: IH = 150 mA min
s Repetitive peak pulse current :
IPP = 80 A (10/1000µs)
MAIN APPLICATIONS
Any sensitive equipment requiring protection
against lightning strikes and power crossing:

(xDSL, T1/ E1, ISDN...)
s Terminals (phone, fax, modem...) and central of-
fice equipment
DESCRIPTION
The SMP80MC-270 is a micro capacitance
transient surge arrestor designed for the
protection of high debit rate communication
equipment. Its micro capacitance avoids any
distortion of the signal and is compatible with
digital line cards (xDSL, T1/E1, ISDN...).

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 are UL497B
approved (file: E136224) and comply with the following standards GR-1089 Core, ITU-T-K20/K21,
VDE0433, VDE0878, IEC61000-4-5 and FCC part 68.
