Temperature Effect on Dark Current Solution

Follow our step by step solution on how to calculate Temperature Effect on Dark Current?

FIRST Step Consider the formula

I da = I d \cdot 2^{\frac{T 2 - T 1}{10}}

Next Step Substitute values of Variables

∴

I da = 11nA \cdot 2^{\frac{50°C - 40°C}{10}}

Next Step Convert Units

∴

I da = 1.1E-8A \cdot 2^{\frac{323.15K - 313.15K}{10}}

Next Step Prepare to Evaluate

∴

I da = 1.1E-8 \cdot 2^{\frac{323.15 - 313.15}{10}}

Next Step Evaluate

∴

I da = 2.2E-08A

LAST Step Convert to Output's Unit

∴

I da = 22nA

How to Evaluate Temperature Effect on Dark Current?

Temperature Effect on Dark Current evaluator uses Dark Current in raised temperature = Dark Current*2^((Changed Temperature-Previous Temperature)/10) to evaluate the Dark Current in raised temperature, The temperature effect on dark current is often referred to as thermal excitation. This is because the dark current in photodetectors, such as photodiodes, is often caused by the thermal excitation of carriers. This process depends critically on the temperature and can increase the dark current. Dark Current in raised temperature is denoted by I_da symbol.
