Defining Diode Data Sheet Parameters

When consulting a data sheet for specifications of a part, it is, of course, important to take the
meaning intended by the authors of the data sheet. The importance of this obvious idea plays it-
self out in the ability to make wise part selections in the course of a new design or in the search
for a replacement part.
This application note will take the reader on a tour of parameters used by Advanced Power Tech-
nology in their diode data sheets. In most cases the intent will be to define and explain. In a few
cases more discussion will be provided to clarify the usage of data sheet information. The note
will be divided into sections corresponding to the sections of the data sheets. It is recommended
that the reader refer to the data sheet for the APT15D60B while reading this application note.
This data sheet is referred to at several points in the note and is available on APT’s website:

Nomenclature
In this document lower case letters will be
used for instantaneous values of signals, and
upper case letters will be used for limits, av-
erages, and D.C. values. Consequently, i
R
is
the instantaneous value of the diode reverse
current, whereas I
R
is the specified D.C. re-
verse current under certain conditions of re-
verse voltage, V
R
, and case temperature T
C
.
In data sheets this distinction is sometimes
not made. An example of using a capital let-
ter two different ways is found in the data
sheets in the sections dealing with maximum
D.C. reverse voltage, V
R
, and junction ca-
pacitance, C
T
. The voltage at which the
junction capacitance C
T
is measured is 200
V. That voltage is called V
R
to designate it
as the applied D.C. reverse voltage. It is left
therefore to the reader to discern from the
context whether V
R
is the maximum D.C.
reverse voltage or the applied D.C. reverse
voltage.
