DSL01-xxxSC5 Secondary protection for DSL lines Features 4 Low capacitance devices: DSL01-xxxSC5: Delta C = 3.5 pF typ 5 3 High surge capability: 30 A - 8/20 s 2 Voltage: 8 V, 10.5 V, 16 V, and 24 V 1 RoHS package SOT23-5L (SC-59) Benefits Transil mode will clamp ESD and low energy Figure 1. Functional diagram surges without disturbing line drivers during transmission while high energy surges will be 1 - 5 short circuited to avoid line driver damage. The low capacitance makes it suitable for ADSL2+ and VDSL signals. Complies with the following standards 3 - 4 IEC 61000-4-2, level 4 Pin 2: Not to be connected 15 kV (air discharge) 8 kV (contact discharge) MIL STD 883G-Method 3015-7: Class 3 Description 25 kV (Human body model) This device combines a Transil used for low IEC 61000-4-5, level 2: 24 A, 8/20 s energy surges and a Trisil for high energy surges. This combination provides a surge / Applications capacitance trade-off compatible with high debit rates such as ADSL2+ and VDSL. The Secondary protection to be located after the combination on the same die makes it compatible transformer of ADSL and VDSL modem either with SOT23-5L package. on central office or subscriber side. Replaces crowbar protection located on primary side.
