Positive surge

Negative surge

Please note that the KBMF01SC6 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 the Negative Surge figure.

3. LATCH-UP PHENOMENA

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 KBMF01SC6 provides a high immunity to latch-up phenomena by

smoothing very fast edges.
