Good evening everyone! I am trying to identify the 3-legged smd component marked "99" on the attached photo of the FLUKE79III electronic card .... I am also attaching the general photo of the multimeter ... Could someone help me?? Thank you for your patience and dedication.

I would expect BAV99 dual diode for some kind of clamping to rail. Not sure as it would require a bit more reverse engineering.

I also have a Fluke 79III and opened it up. This is what the parts in my device look like, maybe this will help you.
