|HP-41C/CV/CX Battery Pack Circuit (burnt diode)|

As a HP-41CV (since 1980, and lately HP50g) owner, I need your help to solve this puzzle.
One of the diodes in the Battery Pack (HP 82120A) failed. However, HP decided to hide the identification of the components, put his own ID on them. Therefore, I was not able to recognize and replace it. The marks on it are:
(M)K 020 057 218
Does anybody know what this translates into?
I've found a Motorola Diode with very similar looks: 1N 75 1A 615 But, I don't know if this is the same thing.
If someone has the list of components, or better yet, a Circuit Schematic, or a link to a previous post.. I'd highly appreciate it. My searches returned almost nothing.
Thank you and happy HP days,
