P-TYPE (BORON DOPED)
ELECTRIC FIELD
N-TYPE (PHOSPHORUS DOPED)

Oscilloscope: V-I Characteristic

-40V (Breakdown) 0V +2V (Forward)

ANALYTICS ENGINE

DEPLETION WIDTH
0.52 µm
DIFFUSION CURRENT
0.00 mA
JUNCTION REGIME
Equilibrium
Engineering Note:
Zener/Avalanche breakdown occurs near -33V to -35V. Beyond this, the depletion region collapses due to impact ionization.
