SMP100LC
Trisil™ for telecom equipment protection
Features
■ Bidirectional crowbar protection
■ Voltage range from 8 V to 400 V
■ Low capacitance from 20 pF to 45 pF @ 2 V
■ Low leakage current: I
R
= 2 µA max
■ Holding current: I
H
= 150 mA min.
■ Repetitive peak pulse current:
I
PP
= 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
■ IEC 61000-4-2 level 4
■ TIA/EIA IS-968
■ UL497B recognized, UL file E136224
Applications
Any sensitive equipment requiring protection
against lightning strikes and AC power faults.
These devices are dedicated to central office
protection as they comply with the most stressful
standards. Their low capacitances make them
suitable for xDSL.
Description
The SMP100LC is a series of low capacitance
transient surge arrestors designed for the
protection of high data rate communication
equipment. The low capacitance of the devices
avoids any distortion of the signal and is
compatible with digital transmission line cards
(xDSL, ISDN...).
SMP100LC series tested and confirmed
compatible with Cooper Bussmann Telecom
Circuit Protector TCP 1.25A.
The SMP100LC-xxx with the fuse TCP1.25A or
TCP2A is compliant with Telcordia GR1089
(lightning and AC power fault tests),
ITU-T K20/K21 (lightning and AC power fault
tests), TIA/EIA-IS-968 (formerly FCC Part 68
lightning tests), and UL60950 (AC power fault
tests). The use of the TCP1.25A allows the
SMP100LC-xxx to be safe for the 2nd level (B
criteria) AC power fault tests.
