how many volts to work
0.7V
forward bias
acts as closed switch (conductor)
reverse bias
acts as open switch (insulator)
reverse bias breakdown
max V until diode goes back to conductor if wired backwards
zener diode
Allows current flow in one direction, but also can flow in the reverse direction when above breakdown voltage
anode vs cathode
pos vs neg
depletion zone
space between diode (neutral)
ratings used
I and V (PIV- peak inverse voltage)
rectifiers
Improve V or I, AC into DC
full wave rectifier
2 diodes AC to DC (center-tap transformer)
bridge rectifier
4 diodes for full voltage
caps and resistor with diode circuit
steady DC charge
