AN2064 - APPLICATION NOTE
Figure 8 shows the time current curves of the TCP fuse series. This figure is used to verify use of the
TCP1.25A with the SMP100MC-270. For the second level, the fuse has to blow before the TRISIL is dam-
aged, so to verify this point we must compare the ITSM points of the SMP100MC with the time current
points of the TCP1.25A. Please note that the ITSM points are given in peak values while the TCP curve is
given in rms values.

The comparison of TCP1.25A and SMP100MC datasheet values shows that this solution is convenient for
this application. The next section will refer to test performed on such a module.
