Forward Biased Diode Capacitance
Diodes have two main capacitance components when forward biased: transition capacitance and diffusion capacitance. Let's discuss why diffusion capacitance is larger than transition capacitance in a forward biased diode.

Transition Capacitance
- Transition capacitance is also known as depletion capacitance.
- It is formed due to the width of the depletion region in the diode.
- This capacitance decreases as the diode is forward biased because the depletion region narrows.

Diffusion Capacitance
- Diffusion capacitance is due to the charge carriers injected into the depletion region.
- When the diode is forward biased, more charge carriers are injected into the depletion region, increasing the diffusion capacitance.
- This capacitance is larger than transition capacitance in a forward biased diode due to the increased number of charge carriers.

Conclusion
In a forward biased diode, the diffusion capacitance is larger than the transition capacitance due to the increased charge carrier injection into the depletion region. This results in higher diffusion capacitance values compared to transition capacitance values.
