Figure 3.25 shows protection of a SLIC using 20 W series resistors on both Tip and Ring in
addition to Teccor’s Battrax (B1100CC) and a diode bridge (General Semiconductor part
number EDF1BS). However, the overshoot caused by the diode bridge must be considered.
The series resistance (a minimum of 20 W on Tip and 20 W on Ring) limits the simultaneous
surge currents of 100 A from Tip to Ground and 100 A from Ring to Ground (200 A total) to
within the surge current rating of the SA-rated SIDACtor device and Battrax. The diode
bridge shunts all positive voltages to Ground, and the B1100CC shunts all negative
voltages greater than |-VREF -1.2 V| to Ground.
