Web9.4 Applications of Schottky Diodes • I0 of a Schottky diode is 103 to 108 times larger than a PN junction diode, depending on φB. A larger I0 means a smaller forward drop V. • A Schottky diode is the preferred rectifier in low voltage, high current applications. I V PN junction Schottky φB I V PN junction Schottky diode φ B diode q kT ... WebThe semiconductor composition of a Schottky diode is slightly different from a normal diode, and this results in a much smaller forward voltage drop, which is usually between …
WebIn silicon diode, 0.6 to 0.7 volts is wasted to turn on the diode, whereas in schottky diode, 0.2 to 0.3 volts is wasted to turn on the diode. Therefore, the schottky diode consumes less voltage to turn on. The voltage needed to turn on the schottky diode is same as that of a germanium diode.
WebThe Schottky barrier is the rectifying barrier for electrical conduction across heterojunction [3], either the metal-semiconductor junction or semiconductor-semiconductor junction, and, therefore, is of vital importance to the successful operation of any semiconductor device.
