® SMP100MC
TRISIL™ FOR TELECOM EQUIPMENT PROTECTION
FEATURES
Bidirectional crowbar protection
Voltage: range from 120V to 270V
Low VBO / VR ratio
Micro capacitance from 20pF to 30pF @ 50V
Low leakage current : IR = 2µA max
Holding current: IH = 150 mA min
Repetitive peak pulse current :
IPP = 100 A (10/1000µs)
MAIN APPLICATIONS
Any sensitive equipment requiring protection
against lightning strikes and power crossing.
These devices are dedicated to central office pro-
tection as they comply with the most stressfull
standards.
Their Micro Capacitance make them suitable for
ADSL2+ and low end VDSL.
DESCRIPTION
The SMP100MC is a series of micro capacitance
transient surge arrestors designed for the protec-
tion 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...).
Compatible with Cooper Bussmann fuse:
TCP 1.25A.
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 UL60950, 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.

These topologies, using SMP100MC from ST and
TCP1.25A from Cooper Bussmann, have been
functionally validated with a Trisil glued on the
PCB. Following example was performed with
SMP100MC-270 Trisil. For more information, see
Application Note AN2064.
Test conditions:
2/10µs + and -2.5 and 5kV 500A (10 pulses of each
polarity), Tamb = 25°C
