NOTES: 4. Typicals are at TJ = 25°C and represent most likely parametric norm.
5. Limits are 100% production tested at 25°C.
6. The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown
Voltage Tolerance ±[(∆VR/∆T)(65°C)(VR)]. ∆VR/∆T is the VR temperature coefficient, 65°C is the temperature range from – 40°C to the
reference point of 25°C, and VR is the reverse breakdown voltage. The total over-temperature tolerance for the different grades is shown
below:
C-grade: ±1.15% = ±0.5% ±100ppm/°C x 65°C
D-grade: ±1.98% = ±1.0% ±150ppm/°C x 65°C
E-grade: ±2.98% = ±2.0% ±150ppm/°C x 65°C
