SMP100MC
Trisil™ for telecom equipment protection
Features
■ Bidirectional crowbar protection
■ Voltage: range from 140 V to 400 V
■ Low VBO / VR ratio
■ Micro capacitance from 15 pF to 30 pF @ 50 V
■ Low leakage current: IR = 2 µA max
■ Holding current: IH = 150 mA min.
■ Repetitive peak pulse current:
IPP = 100 A (10/1000 µs)
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).
Complies with the following standards
■ GR-1089 Core
■ ITU-T-K20/K21
■ IEC 61000-4-5
■ TIA/EIA IS-968
■ UL497B recognized, UL file E136224
Applications
Any sensitive equipment requiring protection
against lightning strikes and power crossing:
■ Terminals (phone, fax, modem...) and central
office equipment
■ ADSL2+ and low end VDSL
SMB
(JEDEC DO-214AA)
Description
The SMP100MC 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 line cards (ADSL, VDSL,
ISDN...).
SMP100MC series has been tested and
confirmed compatible with Cooper Bussmann
Telecom Circuit Protector TCP 1.25 A.

2 Application information
In wire line applications, analog or digital, both central office and subscriber sides have to be
protected. This function is assumed by a combined series / parallel protection stage

Ring
relay
Line
Line
Ex. Analog line card
Ex. ADSL line card or terminal
In such a stage, parallel function is assumed by one or several Trisil, and is used to protect
against short duration surge (lightning). During this kind of surges the Trisil limits the voltage
across the device to be protected at its break over value and then fires. The fuse assumes
the series function, and is used to protect the module against long duration or very high
current mains disturbances (50/60Hz). It acts by safe circuits opening. Lightning surge and
mains disturbance surges are defined by standards like GR1089, TIA/EIA IS-968,
ITU-T K20.
