Note 1: All devices are 100% production tested at +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Note 2: The limit over the full temperature range for the reverse breakdown voltage tolerance is defined as:
[VRTOL] ±[(∆VR / ∆T) X (max∆T) X (VR)]
where ∆VR / ∆T is the VR temperature coefficient, max∆T is the difference from the +25°C reference point to TMIN or TMAX,
and VR 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.
