I am trying to identify a diode I found on the DC-DC converter flex PCB inside my WM F707 that I am trying to restore. Could anyone help me find out what this is or suggest an alternative? I am looking for diode D803 (type CL-70G-CD): This seems to be a 3-pin diode that is entirely unknown to me. I could not find spec sheets and have not been able to identify alternatives: I think the component is labelled 10-T (or: IO-T?) on-board:
The part you circled in red is Q803, an NPN transistor, it's not a diode. D803 is an LED, Light Emitting Diode. In the D803 symbol there are two arrows pointing out from the diode, this indicates that it emits light.
Thanks for pointing out my mishap. I am aware of the PCB label for the LED, but simply mixed up two components. The issue has been resolved.
Just to wrap up: Components starting with a Q are transistors (typically 3 leads like this SOT23 package), components with a D are diodes, typically 2 leads. But sometimes diodes also come in a SOT23 or similar package, with only 2 funtional leads. And some zener diodes or adjustable diodes may have 3 leads.
