ESD application hints

To improve the ESD robustness of this device

above specified

±2KV/HBM external blocking ca-

pacitors must be used. Nevertheless the max. en-

ergy which can be clamped by this device should

not exceeds 0.2mJ for each pin. An equivalent in-

put diagram for calculation can be seen in fig. 9.
