Hello,
Can you provide the required Clearance and Creepage Distance for the ISO121BG ?
Is this information available?
Thank you!
Hi Jim!
I hope you're doing well.
I went to the TI packages site: http://www.ti.com/packaging/docs/searchtipackages.tsp?packageName=DIP
Identified the package type as CDIP SB JVD from the datasheet.
Found the associated package drawing from the packages site: http://www.ti.com/lit/ml/mcdi039/mcdi039.pdf
Creepage is the shortest distance between two conductive parts measured along the surface of a solid insulation.
Clearance is the shortest distance between two conductive parts measured through air.
I'll use nominal values in inches for the calculations.
Creepage: 2*((0.065+0.030)/2) + ((0.610+0.580)/2) = 0.69 inches
Clearance: ((0.012+0.008)/2)+ 0.6 = 0.61 inches
Provided a picture to help the customer understand where my measurements came from.
