SMP75-8
TRISILTM FOR TELECOM EQUIPMENT PROTECTION

FEATURES

Bidirectional crowbar protection Voltage: 8V Low leakage current : IR = 2uA max Holding current: IH = 150 mA min Repetitive peak pulse current : IPP = 75 A (10/1000us)

MAIN APPLICATIONS Any sensitive equipment requiring protection against lightning strikes and power crossing:

SMB (JEDEC DO-214AA)

Ethernet, T1/E1 Table 1: Order Code Part Number SMP75-8

DESCRIPTION The SMP75-8 is a very low voltage transient surge arrestor especially designed to protect sensitive telecommunication equipment against lightning strikes and other transients. Its low voltage makes it suitable to protect low voltage transformer in T1/ E1, ethernet links without saturation of the transformer. 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 UL1950, 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 GR1089 Core, ITU-T-K20/K21, VDE0433, VDE0878, IEC61000-4-5 and FCC part 68.
