The CX77301 is a Class I device. Figure 6 lists the Electrostatic

Discharge (ESD) immunity level for each pin of the CX77301

product. The numbers for each pin in Figure 6 specify the ESD

threshold level where the I-V curve between the pin and ground

starts to show degradation. If ESD damage threshold magnitude

is found to consistently exceed 2000 volts on a given pin, this so

is indicated. If ESD damage threshold below 2000 volts is

measured for either polarity, numbers are indicated that

represent worst case values observed in product

characterization.

Various failure criteria can be utilized when performing ESD

testing. Many vendors employ relaxed ESD failure standards

which fail devices only after “the pin fails the electrical

specification limits” or “the pin becomes completely non-

functional”. Skyworks employs most stringent criteria, fails

devices as soon as the pin begins to show any degradation on a

curve tracer.

To avoid ESD damage, both latent and visible, it is very important

that the product assembly and test areas follow the Class-1 ESD

handling precautions listed in

Table 5.
