Apa itu Diod . Control the Flow. Diode Characteristics 3. The materials in a Schottky diode are slightly different from a normal diode, and this results in a much smaller forward voltage drop, which is usually between 0.15V and 0.45V. When this voltage exceeds 0.7V, the diode is set to breakdown and the diode starts conducting and allows current to flow. A Schottky diode is also known as a hot carrier diode; it is a semiconductor diode with a very fast switching action, but a low forward voltage drop. I use a regular diode (1N4007) as a flyback diode for a 250ma 5v fan.My transistor is a 2N 3904 and the PWM generator is an attiny85:.
