Notes:
1. The values in this table correspond to the nominal creepage and clearance values as detailed in “10. Package Outline:
16-Pin Wide Body SOIC” , “12. Package Outline: Narrow Body SOIC” , “14. Package Outline: 14 LD LGA (5 x 5 mm)” ,
and “16. Package Outline: 14 LD LGA with Thermal Pad (5 x 5 mm)” . VDE certifies the clearance and creepage limits
as 4.7 mm minimum for the NB SOIC-16 and 8.5 mm minimum for the WB 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 and 7.6 mm minimum for the WB SOIC-16 package.
2. To determine resistance and capacitance, the Si823x is converted into a 2-terminal device. Pins 1–8 (1-7, 14 LD LGA)
are shorted together to form the first terminal and pins 9–16 (8-14, 14 LD LGA) are shorted together to form the second
terminal. The parameters are then measured between these two terminals.
3. Measured from input pin to ground.
