TISP4xxxJ1BJ Overvoltage Protector Series
ITU-T K.20, K.45 and K.21 Designs (Continued)
An ITU-T compliant design would probably require the replacement of the fuses by coordination resistors. With a
±
410 V off-state voltage, this
may seem unnecessary as modern primary protectors will switch at lower voltages and automatically coordinate. On a perfect longitudinal
waveform this is true. However, the ITU-T also applies a transverse (metallic) test as well, to simulate non-simultaneous switching of the
primary protection. In this case, one conductor is grounded, which places the RING to TIP protection in parallel with the unswitched primary
protector. The
±
270 V off-state voltage is likely to be lower than the primary switching voltage and there isn’t coordination. Under GR-1089-
CORE conditions with non-simultaneous switching, the 100 A 10/1000 current, which should have gone through the unswitched primary
protector, is diverted through the top arms of the Y into the switched primary, causing a 200 A current flow in that primary protector.

Asymmetrical Designs
These designs are for special needs, where the RING to TIP protection voltage must be different to the RING to GROUND and TIP to
GROUND voltages. ADSL modem interfaces often have a need for asymmetric voltage limiting, see Figure 16. Here, the RING to TIP voltage
limitation is given by the d.c. blocking capacitor, C1, and the RING to GROUND and TIP to GROUND limitation is insulation breakdown. Often
the breakdown limit is set by the spacing of the PW (Printed Wiring) tracks. Figure 17 shows a solution. Using two
±
165 V V
(BO)
parts for Th1a
and Th1b, the RING to TIP voltage is limited to
±
330 V. Using a higher voltage
±
350 V V
(BO)
part for Th2 limits the insulation stress to
±
515 V.
Figure 17 and its following table is for a GR-1089-CORE compliant design.
