Trying to identify these 2 diodes but I am having trouble with it. They dont need to be replaced or anything, im just trying to recreate this flash tube circuit. For all I know, the label on it says kv23 with a line above the 2 and the 3. I attempted to measure the voltage drop between them with a multimeter and I dont get any measurements. They are both labeled “S4” and “S5” on the board, while the other diodes are labeled as S1, S2, S3. I tried to find information on a “kv23” diode and found nothing. What should I do now?
One thing I forgot to mention, this is a circuit from 1992, so there unfortunately are no schematics on this. I am mostly certain these diodes were long discontinued but I know there is an alternative I can use, I just dont know any info on these diodes
Hello,
Welcome to the DigiKey TechForum, I wasn’t able to find any information on these parts either. With no information on the specifications and you’re making an old circuit from new parts you will just need to breadboard and try different parts to see what works best.
