Features
■ Bidirectional crowbar protection ■ Voltage: range from 140 V to 400 V ■ Low VBO / VR ratio ■ Micro capacitance from 15 pF to 30 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) 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 ■ TIA/EIA IS-968 ■ UL497B recognized, UL file E136224
Applications
Any sensitive equipment requiring protection against lightning strikes and power crossing: ■ Terminals (phone, fax, modem...) and central office equipment ■ ADSL2+ and low end VDSL
Description
The SMP100MC is a series of micro capacitance transient surge arrestors designed for the protection 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...). SMP100MC series has been tested and confirmed compatible with Cooper Bussmann Telecom Circuit Protector TCP 1.25 A. TM: Trisil is a trademark of STMicroelectronics. SMB (JEDEC DO-214AA)
