Handling Precautions
Although ESD protection circuitry has been designed into the the VMEM5Q, proper precautions should
be taken when handling and mounting. VI employs a Human Body Model and a Charged-Device Model
(CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on
the circuit parameters used to define the model.

Human Body Model
2000V
Charged Device Model

Suggested IR Profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
conditions. Figure 4 shows max temperatures and lower temperatures can also be used e.g. peak
temperature of 220C.
