That's not a regular Motorola part number. Most likely it was made/selected for a manufacturer. Other than testing for NPN/PNP, there's not much hope of determining what it may correspond to.

Aren't house numbers lovely?

What's it out of, if you know?

Could be a SCR or TRIAC as well....

Cheers!
