Electrostatic Discharge Sensitivity
The CX77304-15 is a Class I device.
Figure 6 lists the Electrostatic Discharge (ESD) immunity
level for each pin of the CX77304-15 product. The numbers in
Figure 6 specify the ESD threshold
levels for each pin where the I-V curve between the pin and ground starts to show degradation.
The ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the
Human Body Model. 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.
