[SOLVED] Temperature coefficient for dark current in photodiode

[Tetik]

How do we interpret the temperature coefficient of dark current in specifications. In some datasheet, we can find 1.15 times/°C.

If I have a delta temperature of 50°C, do I have A) to multiply 1.15 * 50 or B) to powered it 1.15^50.


Thanks for your help.

1.15^50 . A factor of ≈1000 for 50° of temp. rise is reasonable for leakage (or dark) current in silicon.
