ETP01-xx21 Protection for Ethernet lines Features Differential and common mode protection Telcordia GR1089 Intrabuilding: 100 A, 2/10 s ITU-T K20/21: 40 A, 5/310 s Low capacitance: 13 pF max at 0 V UL94 V0 approved resin SO8 package is JEDEC registered SO-8 Benefits TrisilTM technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection. This series is used to help equipment to meet main standards such as UL61950, IEC 950 / CSA C22.2 and UL1459. Figure 1. T1 Complies with the following standards IEC 61000-4-2: Level 4 - 15 kV (air discharge) - 8 kV (contact discharge) MIL STD 883E-Method 3015-7: class3: - 25 kV (Human body model) TELCORDIA GR-1089 Core: 100 A, 2/10 s ITU-T K20/21: 37.5 A, 5/310 s IEC 61000-4-5: 4 kV, 42 , 96 A, 8/20 s IEC 61000-4-4 EFT : 40A (5/50ns) GND GND GND T2 Description This series can meet subscriber and central office requirements. Protection against telecommunications surge standards on: - 10/100 Mbps Ethernet - Ethernet Gigabit - T1 / E1 line cards September 2009 T1 GND T2 Applications Schematic diagram The ETP01 series is a low capacitance transient surge arrestor designed for protection of high debit rate communication network. Planar technology used combines a high surge capability to comply with Telcordia GR1089 Intrabuilding and ITU-T K20/21, and low capacitance to avoid distortion of high speed signals such as Ethernet.
