Handling Precautions

Although ESD protection circuitry has been designed into the the V-Type, 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.

JESD 22-C101

The V-Type 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 V-Type is hermetically sealed so an aqueous wash is not an issue.
