Which characteristic of a Schottky diode makes it a better choice than a silicon junction diode for use as a power supply rectifier?
Pick an answer to check it.
Answer: D. Lower forward voltage drop
A Schottky diode has a low forward voltage drop, about 0.2 to 0.4 V versus about 0.7 V for silicon. Less voltage drop means less power wasted as heat in a rectifier.
Tip: Schottky = low drop, less heat.
