| Model Description | This model is a simple, basic
diode
model based
on the standard SPICE diode with the addition of reverse
recovery.
During
reverse recovery, the diode current exponentially decays
to the reverse
saturation current, independent of the diode reverse
voltage. Upon request, a SPICE subsircuit is available for this Basic Diode Model. |
| Model Parameters | Model parameters are the same
as
those of the
standard SPICE diode model with the addition of the
carrier lifetime
parameter
"Tau". The standard SPICE diode includes only the
diffusion transit
time
parameter "TT". Both "TT" and "Tau" are required to
characterize
reverse recovery.
Data sheets frequently give measurements of Qrr
and
trr. Approximate conversions to TT and Tau
are: |
| Performance Level: | BASIC |
| Quality Classification: | 3B This model has been extensively used. Parameter extraction is available. |
