There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. Attention: Observe Precautions for Handling Electrostatic Sensitive Devices ESD Human Body Model (HBM) = 500 V (Class 1B) ESD Machine Model (MM) = 200 V (Class B) ESD Charged Device Model (CDM) = 1000 V (Class 4) Electrostatic Discharge (ESD) can damage this device, which must be protected from ESD at all times. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY16406-381LF are provided in Table 2. Electrical specifications are provided in Tables 3. Typical performance characteristics of the SKY16406-381LF are illustrated in Figures 3 through 9.
