Calcolatore Potenza MOSFET — Formula
## Diode Forward Voltage Drop
When current flows through a diode, it drops a nearly constant forward voltage V_f.
### Formula
**V_out = V_supply - V_f**
**P_diode = V_f x I_load**
Silicon diodes drop about 0.7 V, Schottky diodes 0.2-0.4 V, and LEDs 1.8-3.3 V depending on color.

Esempio Risolto
A silicon diode (0.7 V drop) in a 5 V circuit carrying 100 mA.
- V_out = 5 - 0.7 = 4.3 V
- I_load = 100 / 1000 = 0.1 A
- P_diode = 0.7 x 0.1 = 0.07 W = 70 mW
