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 OD is applied before Vcc.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and
IR reflow simulation. The SO-720 family is capable of meeting the following qualification tests:
Environmental Compliance

Mechanical Shock
Mechanical Vibration
Solderability
Gross and Fine Leak
Resistance to Solvents
Conditions

MIL-STD-883, Method 2016
Handling Precautions
Although ESD protection circuitry has been designed into the SO-720 proper precautions should be taken when
handling and mounting. VI employs a Human Body model (HBM) and a Man-Man model (MM) for ESD
susceptibility testing and design protection evaluation.

The device is designed to meet the JEDEC standard
for Pb-Free assembly. The temperatures and time
intervals listed are based on the Pb-Free small body
requirements. The SO-720 device is hermetically
sealed so an aqueous wash is not an issue.
