Prompt delivery
I haven't had the chance to use these yet, but wanted to note that delivery was very prompt and so far everything I ordered (loads of small count discrete components).

Also, no datasheet was availabel from the AllEctronics site, however, I think this is the correct datasheet:

Excellent Photo Diode
I bought five of these for an automatic "on-after-dark" dispaly and they worked perfectly. Also, the location for my projects is exposed to high day time temperatures in direct sunlight. The PD-2's worked perfectly. I want to add that during assembly, an assistant brought me one that had been assembled wrong. The PD-2 was in backward and I thought it would be trashed since he had turned the unit on and left it for some time. We just reversed the diode and switched it on and operation was perfect! Very impressive for the price.
