Notes:
1. The values in this table correspond to the nominal creepage and clearance values as detailed in “6. Package Outline:
16-Pin Narrow Body SOIC”. VDE certifies the clearance and creepage limits as 4.7 mm minimum for the NB SOIC-16
package. UL does not impose a clearance and creepage minimum for component level certifications. CSA certifies the
clearance and creepage limits as 3.9 mm minimum for the NB SOIC-16 package.
2. To determine resistance and capacitance, the Si84xx is converted into a 2-terminal device. Pins 1–8 are shorted
together to form the first terminal and pins 9–16 are shorted together to form the second terminal. The parameters are
then measured between these two terminals.
3. Measured from input pin to ground.
