Hi PYTsai,

I do not currently have this data. I will go to the lab and test it. this will take a week.

Hi PYTsai,

I tested 5 devices. Vka = Vref.
The averages are as follows.
-40C: 0.44mA
25C: 0.48mA
90C: 0.52mA

Hi Marcoo,

We are looking for cathode current, but the data you give us is voltage. would you clarify? thanks!
