7-Segment Display with Decimal Common Cathode

IS

Saturation current

Current flow resulting from the diffusion of minority carriers. The value flow strongly affects the diode current. Typical values are between 1e-1 and 1e-18.

1e-14 A

N

Emission coefficient

Ideality factor. The value affects the exponential of the forward diffusion current. Set a low value, such as 0.1, to model a more ideal and sharp I/V curve.

1

RS

Series resistance

Parasitic resistance of the diode. Modeled as a series resistor.

0 Ω

IBV

Breakdown current

Current flowing through the diode when the diode conducts in reverse.

100p A

BV

Reverse breakdown voltage

Voltage at which the diode conducts in reverse.

1e30 V

CJO

Zero-bias junction capacitance

Capacitance of BE junction with no external voltage applied. The value affects the capacitance of the diode.

0 F

M

Junction grading coefficient

Indicator of the doping profile of the junction.

0.5

VJ

Junction potential

Built-in potential which means the potential across the depletion region in the thermal equilibrium. The value affects the capacitance of the diode.

1 V

ION

On current

Current above which the LED appears lit. The value has no effect on the model.

20m A
