Fig. A5:
Remaining voltage at both stages S1 (Vinput) and S2 (Voutput) during ESD surge.
Please note that the KBMFxxSC6 is not only acting for positive ESD surges but also for negative ones. For
these kind of disturbances it clamps close to ground voltage as shown in Fig. A5b.
The early ageing and destruction of IC’s is often due to latch-up phenomena which is mainly induced by
dV/dt. Thanks to its structure, the KBMFxxSC6 provides a high immunity to latch-up phenomena by
smoothing very fast edges.

when the gap across lines decreases, this is the reason why we provide crosstalk measurements for
monolithic device to guarantee negligeable crosstalk between the lines. In the example above the ex-
pected signal on load R

signals in the disturbing line. The perturbed line will be more affected if it works with low voltage signal or
high load impedance (few k
).
