® 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.
