I was wondering how do you determine if a KES-400A Diode is good?
I recently ordered 3PHR-803A KES-400A sleds from Daedal. I harvest them from their sleds, and wanted to determine if they are good. So I decided that the best way is to take my trusty Fluke 189 and measure the diodes. Here are my results:
Since the Blue/Violet diode portion gave me OL reading on 2 of the diodes but a 3.26V value for #1. I did noticed all 3 lit up when the diode's breakdown voltage was being measured.
Does that mean 1 or 2 of my Blue/Violet LD is bad, or measuring the BDV not a valid way to check if it's a good diode?
Thanks.
FYI:

#1 | #2 | #3 | ||
Pin | Desc | BDV | BDV | BDV |
1 | VLD (Blue/Violet) | 3.26V | OL | OL |
2 | IRLD (IR) | 1.45V | 1.45V | 1.45V |
3 | PD | 0.88V | 0.94V | 0.86V |
4 | RLD (red) | 1.77V | 1.77V | 1.77V |
