3.1 ESD application hints
To improve the ESD robustness of this device above specified ±2 kV/HBM external blocking
capacitors must be used. Nevertheless the max. energy which can be clamped by this
device should not exceeds 0.2mJ for each pin. An equivalent input diagram for calculation
can be seen in Figure 11.
