The boldface (overtemperature) 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 tempera- ture 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 overtemperature tolerance for the different grades follows: a. C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C b. D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C Example: The C-grade LM4040-2.5 has an overtemperature Reverse-Breakdown Voltage tolerance of ±2.5 × 1.15% = ±29 mV.
