Did he buy those from 2D503Bs you, @Robert ?

Also, why the 253? All I can divine from the datasheet is wider operating temp range...

You mean the JRC072?

Thought the top was the proud batch and date code. Tired brain.

"intended for application as the switching elements in pulse high-speed devices of nanoseconds"

Do they clip nice?

 

[Robert]

Is this really happening? I can't even be sure anymore.

Well played sir... well played.

Thanks, Louis Rossmann...

I've never seen this before, but damn that's smart. I'm assuming installing resistors/diodes vertically it's to make it easier to:
a) probe
b) remove

Anything else?

Anything else?

Heat dissipation and physical real estate.

It's pretty common to see higher wattage resistors installed vertically to prevent damage to the board if/when they heat up.

It's kinda annoying when it comes to tracing because the end I need to measure is always the (inaccessible) one on the bottom...

Yeah, 8th watt resistors are horrible, so damn tiny.
