Absolute Maximum Ratings and Handling Precautions
Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not implied or
any other excess of conditions represented in the operational sections of this data sheet. Exposure to absolute maximum ratings
for extended periods may adversely a ect device reliability.
Although ESD protection circuitry has been designed into the VT-501, proper precautions should be taken when handling and
mounting, VI employs a Human Body Model and Charged Device Model for ESD susceptibility testing and design evaluation.
ESD thresholds are dependent on the circuit parameters used to de ne the model. Although no industry standard has been
adopted for the CDM a standard resistance of 1.5kOhms and capacitance of 100pF is widely used and therefor can be used for
comparison purposes.

Suggested IR Pro le
Devices are built using lead free epoxy and can be subjected to standard lead free IR re ow conditions shown in Table 5. Contact
pads are gold over nickel and lower maximum temperatures can also be used, such as 220C.
