Maximum Ratings

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 aﬀect device reliability.

Although ESD protection circuitry has been designed into the VT-702, 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 deﬁne 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 Proﬁle

Devices are built using lead free epoxy and can be subjected to standard lead free IR reﬂow conditions shown in Table 6. Contact pads are

gold over nickel and lower maximum temperatures can also be used, such as 220°C.
