Functional operation is not implied at these or any other conditions in 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. Table 2.

Table 3. Environmental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Moisture Sensitivity Level MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 MIL-STD-883 1 Conditions Method 2002 Method 2007 Method 2003 Method 1014 Method 2016 Handling Precautions Although ESD protection circuitry has been designed into the the VVC4, 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. Table 4. ESD Ratings Model Human Body Model Charged Device Model Minimum 1500 1000 Conditions MIL-STD-883 Method 3115 JESD 22-C101 The VVC4 is qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and time intervals listed are based on the Pb-Free small body requirements and parameters are listed in the table below. The contact pads are gold over nickel so lower IR reflow temperatures such as 220°C can be used (device is backwards compatible with a lead solder assembly). The VVC4 is hermetically sealed so an aqueous wash is not an issue. Table 5.
