AN2064 - APPLICATION NOTE
5. US market telecom protection tests
A PCB has been developed according to the criteria established earlier (see figure 9). These boards,
equipped with two fuses TCP1.25A from Cooper Bussmann and two TRISILs SMP100MC-270, have been
tested.
Figure 9: Picture of the developed board
The schematic of these tested boards is given in the figure 10 and performed tests were based on Telcor-
dia (Bellcore) GR1089 for both lightning and power mains disturbances.
. Lightning surge 10/1000µs +/-1kV 100A (25 pulses in each polarity)
. Lightning surge 2/10µs +/-2.5kV and 5kV 500A (10 pulses in each polarity)
. Power mains disturbance 600V 3A 1.1s
. Power mains disturbance 277V 25A 15mn
. Power mains disturbance 600V 60A 5s
