It is an ellusive part to find.
Closest I could get was this one.
I would check it under voltage to find out the zener voltage(11V or 7.1V).
Use a DC P.S(start with 12V and then with 15V) put a series resistor to allow about 10-20mA of current and measure the zener voltage.

Sir mityeltu . . . . .
I can’t see those being other than just one watt encased Zener diodes, possibly at some custom 7 volt variant from the normal assigned bracketing values of 6.8-----7.5 VDC Zener thresholds..
How about doing a non destructive testing, using a 24VDC supply and a series current limiting resistor of 1k to its cathode.
That should tickle the unit enough to see what its Zener threshold is being .
If that gives no reading, suspicion that you just might have yourself a special unit on up in the ~70 V region, and use a higher 100VDC and a 10 K resistor to do the same test.
That house number is being a dead end lead, otherwise, but Motorola did use that diode prefix in olden tymes on some of their diodes...

Is the data requirement as a function of part replacement or so you can use the stock you have for some other purpose?
If it is from existing equipment then the schematic of it in-situ may reveal some information.
If it is from a 'found' (or purchased) bandolier of assorted components then it may well be a transient absorber since (in my personal experience) there seems to be a lot of them about in the surplus market.....

I work in a component deication lab. This part was sent for testing at 5.5v (according to the customer who purchased them from a clearing house supplier). However, there is no datasheet so I have no idea what breakdown current limit should be to determine pass/fail criteria.
I am led to believe they were manufactured by Microsemi, so i am going to reach out to them today.
Thank you for all the advice/support/help. Wish me luck.

Very decent of you. Thanks.
