Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow
simulation. The VL-821 family is capable of meeting the following qualification tests:

Although ESD protection circuitry has been designed into the VL-821 proper precautions should be taken when handling
and mounting. VI employs a human body model (HBM) and a charged device model (CDM) for ESD susceptibility testing
and design protection evaluation.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Functional operation is not
implied at these or any other conditions in excess of conditions represented in the operational sections of this datasheet.
Exposure to absolute maximum ratings for extended periods may adversely affect device reliability. Permanent damage is
also possible if E/D is applied before V
