I found a few metadata/detail issues during the check: missing pin descriptions, missing package metadata, and a 70 V description value that conflicts with the datasheet’s 80 V VCEO. I’m correcting those documented fields now before wrapping up.
The independent sanity check agreed the footprint and electrical specs match the base DIP-4 VO617A-3; the only clarity issue is pin 2 using “C” for cathode while pin 4 also uses “C” for collector. I’m renaming pin 2 to “K” to avoid ambiguity.
Completed the VO617A-3 review and updates. I set the Datasheet URL to the official Vishay PDF, corrected/filled metadata, added pin descriptions, corrected the description’s VCEO value to 80 V, and verified the DIP-4 footprint matches the base through-hole VO617A-3.
Open items:
Pin 2 and pin 4 still both display as C; descriptions disambiguate them, but pin 2 would be clearer as K/CATHODE.
The footprint is valid for base through-hole VO617A-3, not SMD or wide-body suffix variants.
