Hello. This if my first post on this forum and thanks for allowing me the opportunity to interface with you members. I have been a long time junkie when it comes to various hobbies from carpentry (framing & finish) to machining (mini mill & mini lathe) to auto repair, general contracting (slab to roof) to all other sorts of other things. I am in my early sixties, am retired from the US Army after 20 years, and unfortunately am 100% rated disable by the VA for several service connected disabilities. So my life now is solely around my wife and my hobbies.
I am having an issue with a laser circuit I am working on. I lost the laser-photo diode and have to replace it with another laser-photo diode. I also believe that this is a current driven system. But the main issue is that there are three components that I can not find any information on.
Anyways, I have identified most of the components on the laser driver board but am having problems identifying 3 components on the SMD board. The specific components are the diode (either a Zener or Barrier - based solely on an assumption [current limiter maybe???]) that I can not identify at all. It is marked is a while line indicating the polarity and the name "ASb". The other two components are what I believe to be Bi-Polar Junction Transistors ???, one is a PNP the other is a NPN. These are marked "6CW" with an "82" perpendicular to the "W" and the other is marked "5AW" with "60" perpendicular to the "W". BTW, the DC de-coupler??? cap is 1uF.
Anyways, I was hoping that someone here could assist me with identifying replacements for these components.
It is a relatively simple circuit where the input to the photo diode monitor side (laser diode output) of the laser-photo diode limits the driver circuit that drives the laser-photo diode on the laser side. It is a 3VDC system driven by a CR123 battery.
Here is a picture of the SMD board with the components I can not identify circled.
Any assistance would be appreciated.
Picture of the board with the components that I need to identify:
Schematic (I think...my attempt even though I know that it is not as "accurate" as it could be for component identification in a schematic drawing - sorry....)
I want to be sure that the components are replaced before I hook up another laser-photo diode so I do not "burn" the new diode as well.
Any help with this is really appreciated. And again, thanks for allowing me to post here.
