#### Optocoupler

Optocouplers transfer electrical signals between isolated circuits through light, allowing isolation of high voltages from lower voltages.
Diode - 1N5817, Schottky, High Switching Speed
Schottky diode with low forward voltage drop and high switching speeds.
$0.10 Diode - General purpose rectifier, 1A, 1N400X A semiconductor device which passes current in the forward direction (from anode to cathode), and blocks current in the opposite direction. Starting at$0.15
Diode - Zener, 1W, 1N4741A, 1N4748A
A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
Starting at $0.15 Diode - Fast Recovery, 1A, 600V, 1N4937 A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.$0.20
Diode - Silicon Rectifier, 3A, 400V, 1N5404
A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction.
