SMP100LC
TRISIL™ FOR TELECOM EQUIPMENT PROTECTION
FEATURES
■ Bidirectional crowbar protection
■ Voltage range from 8V to 400V
■ Low capacitance from 20pF to 45pF @ 50V
■ Low leakage current : I_R = 2µA max
■ Holding current: I_H = 150 mA min
■ Repetitive peak pulse current:
I_PP = 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 Low Capacitances make them suitable for
ADSL.
DESCRIPTION
The SMP100LC is a series of low capacitance
transient surge arrestors designed for the protec-
tion of high debit rate communication equipment.
Its low capacitance avoids any distortion of the sig-
nal and is compatible with digital transmission line
cards (xDSL, ISDN...).
SMP100LC series tested and confirmed compati-
ble with Cooper Bussmann Telecom Circuit Pro-
tector 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.
