TISP4xxxJ1BJ Overvoltage Protector Series
APPLICATIONS INFORMATION
Y Configuration Design
This protection configuration has three modes of protection. The RING to TIP terminal pair protection is given by the series combination of
protectors Th1a and Th1b, see Figure 11. The terminal pair protection voltage will be the sum of the V(BO), breakover voltage, of Th1a and the
V(BO) of Th1b. Protectors Th1a and Th1b are the same device type and the terminal pair protection voltage will be 2 V(BO)1. For a terminal pair
protection voltage of ±400 V, Th1a and Th1b would have V(BO)1 = ±400/2 = ±200 V.
Similarly for the other terminal pairs, RING to GROUND protection is given by the series combination of Th1b and Th2 and the terminal pair
protection voltage is V(BO)1 + V(BO)2. TIP to GROUND protection voltage will also be V(BO)1 + V (BO)2.
The maximum terminal pair voltage before clipping might occur is the sum of the protector VDRM, off-state voltages, see Figure 12. For RING to
TIP this will be 2 VDRM1. The ±200 V V(BO)1 protectors of the previous example have a VDRM of ±155 V, giving a maximum non-clipping signal
voltage of ±310 V. For RING to GROUND and TIP to GROUND terminal pairs, the maximum non-clipping signal voltage will be VDRM1 + V DRM2 .
Under longitudinal surge conditions, when the prospective currents of the line conductors, IRING and ITIP, are equal, Th2, the ground return
protector, carries the sum of the Th1a and Th1b currents, see Figure 13. The current rating of Th2 must be twice that of Th1a and Th1b.

The main impulse waveforms of the standard are 500 A, 2/10 and 100 A, 10/1000. Assuming fuse current limiters, F1a and F1b, a suitable
Th1a and Th1b protector for these conductor currents is the TISP4xxxH3BJ series of devices. The ground return protector, Th2, must be rated
for at least 1000 A,2/10 and 200 A, 10/1000. A suitable Th2 protector for these ground currents is the TISP4xxxJ1BJ series of devices. This
arrangement is shown in Figure 14 and the following table lists all the catalogue device combinations.
