Handling Precautions
Although ESD protection circuitry has been designed into the the VTC1, 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. Although no industry wide standard has been adopted for the CDM, a
standard HBM of resistance = 1.5kohms and capacitance = 100pF is widely used and therefore can be
used for comparison purposes.

Suggested IR profile
Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow conditions,
Table 7 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C.
