The main impulse voltage wave shape of these recommendations is 10/700. The current wave shape is loading dependent, but it is 5/310 into
a short circuit. To coordinate with a ±400 V primary protector a minimum series resistance of 6.5 Ω is required (“The New ITU-T
Telecommunication Equipment Resistibility Recommendations”, Compliance Engineering Magazine, January-February 2002). The coordination
resistance limits the peak non-truncated current to ±400/6.5 = 62 A. A suitable Th1a and Th1b protector for these conductor currents is the
TISP3xxxT3BJ series of devices, which combine Th1a and Th1b in a single SMB3 package. The ground return protector, Th2, must be rated
for at least 124 A of a 5/310 waveshape. Suitable Th2 protectors for these ground currents are the TISP4xxxH3BJ or TISP4xxxJ1BJ series of
devices. The arrangement is shown in Figure 15 and the following table lists all the catalogue device combinations. Using the SMB3 packaged
TISP3xxxT3BJ saves one third of the PCB placement area compared to solution using three single protector SMB packaged devices.
