Note 1:
All devices are 100% production tested at +25°C and are guaranteed by design for T

= T
MIN
to T
MAX
, as specified.
Note 2:
The limit over the full temperature range for the reverse breakdown voltage tolerance is defined as:
[V
RTOL
] ±[(
V
R
/
T) X (max
T) X (V
R
)]
where
V
R
/
T is the V
R
temperature coefficient, max
T is the difference from the +25°C reference point to T
MIN
or T
MAX
,
and V
R
is the reverse breakdown voltage.
The total tolerance over the full temperature range for the different grades where max
T = +100°C is shown below:
A grade: ±0.6% = ±0.1% ±50ppm/°C
100°C
B grade: ±0.7% = ±0.2% ±50ppm/°C
100°C
C grade: ±1.0% = ±0.5% ±50ppm/°C
100°C
Note 3:
Guaranteed by design.
