Installation Classification
1. The values in this table correspond to the nominal creepage and clearance values as detailed in "7. Package Outline:
2. To determine resistance and capacitance, the Si84xx is converted into a 2-terminal device. Pins 1–4 are shorted
3. Measured from input pin to ground.
8-Pin Narrow Body SOIC" on page 25. VDE certifies the clearance and creepage limits as 4.7 mm minimum for the NB
SOIC-8 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-8 package.
together to form the first terminal and pins 5–8 are shorted together to form the second terminal. The parameters are
then measured between these two terminals.
