1. The quoted values of
∆V
ref
are based on a constant current I
Z
. Two factors can cause
∆V
ref
to change, namely the
differential resistance r
dif
and the temperature coefficient S
Z
.
a) As the max. r
dif
of the device can be 50
Ω,
a change of 0.01 mA in the current through the reference diode will
result in a
∆V
ref
of 0.01 mA
×
50
Ω
= 0.5 mV. This level of
∆V
ref
is not significant on a BZV10 (∆V
ref
< 46 mV),
it is however very significant on a BZV14 (∆V
ref
< 2.3 mV).
b) The temperature coefficient of the reference voltage S
Z
is a function of I
Z
. Reference diodes are classified at the
specified test current, and the S
Z
of the reference diode will be different at different levels of I
Z
. The absolute value
of I
Z
is important, however, the stability of I
Z
, once the level has been set, is far more significant. This applies
particularly to the BZV13 and BZV14. The effect of the stability of I
Z
on S
Z
is shown in Fig.2.
2. All reference diodes are characterized by the ‘box method’. This guarantees a maximum voltage excursion (∆V
ref
)
over the specified temperature range, at the specified test current (I
Z
), verified by tests at indicated temperature
points within the range. V
Z
is measured and recorded at each temperature specified. The
∆V
ref
between the highest
and lowest values must not exceed the maximum
∆V
ref
given. Therefore the temperature coefficient is only given as
