Features
■ Bidirectional crowbar protection ■ Voltage range from 8 V to 400 V ■ Low capacitance from 20 pF to 45 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) Main 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 stressfull 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. Its low capacitance 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 (formely FCC Part 68 lightning tests), UL60950 (AC power fault tests). Moreover, the use of the TCP1.25A allows the SMP100LC-xxx to be safe for the 2nd level (B criteria) AC power fault tests. Order Code 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. Order code Marking SMP100LC-xxx See Section 5 on page 11 SMB (JEDEC DO-214AA)
