8 LED Bar

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. 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
