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
Benefits
■ Trisil™ 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.
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)
Applications
This series can meet subscriber and central office
requirements.
■ Protection against telecommunications surge
standards on:
– 10/100 Mbps Ethernet
– T1 / E1 line cards

Description
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.
