PN SD1528, Suffix "R1"

[ABend.1]

Hello,

I am trying to find any info on obsolete RF transistor MPN SD1528-08R1. I have the datasheet for the base PN itself but I cannot find any documentation that contains or defines the suffix "R1".

Any help would be greatly appreciated.

Thanks,

This transistor dates back to ancient times and was discontinued ages ago.

We are sorry to inform you that no more information is available for it.
