ETP01-xx21 Protection for Ethernet lines Features ■ Differential and common mode protection ■ Telcordia GR1089 Intrabuilding: 150 A, 2/10 µs ■ ITU-T K20/21: 40 A, 5/310 µs ■ Low capacitance: 13 pF max at 0 V ■ UL94 V0 approved resin ■ SO-8 package is JEDEC registered SO-8 Benefits ■ ■ Trisil™ technology is not subject to ageing and provides a fail safe mode in short circuit for a better protection. Figure 1. This series is used to help equipment to meet main standards such as UL61950, IEC 950 / CSA C22.2 and UL1459. 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 µs ■ ITU-T K20/21: 37.5 A, 5/310 µs ■ IEC 61000-4-5: 4 kV, 42 Ω, 96 A, 8/20 µs ■ IEC 61000-4-4 EFT : 40A (5/50ns) T1 GND GND GND GND T2 T2 Description Applications This series can meet subscriber and central office requirements. ■ Schematic diagram (top view) Protection against telecommunications surge standards on: – 10/100 Mbps Ethernet – T1 / E1 line cards 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.
