I'm having trouble identifying a Motorola Optocoupler. It is a 6 pin thru hole device with the following marking;"SOC839A". It also has the Motorola logo on it. I beleive it is a MOC8XXX part. Is there any way to confirm the exact P/N?

Thank you.

Hi Nick,

It's probably one of two devices - MOC8020 or MOC8021 depending on the CTR (Current transfer ratio).

I have always used http://www.icmaster.com for older semiconductor datasheets. (Back in the old days we used to use the IC master data books which cost big time!).

Hope that helps,

Rob.
