Breakdown Voltage Tolerance
maximum difference in temperature from the reference point of +25°C to T
voltage. The total overtemperature tolerance for the different grades in the temperature range where max∆T = +65°C is
shown below:
A grade: ±1.1% = ±0.1% ±100ppm/°C
B grade: ±1.2% = ±0.2% ±100ppm/°C
C grade: ±1.5% = ±0.5% ±100ppm/°C
D grade: ±2.5% = ±1.0% ±150ppm/°C
Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature reverse breakdown voltage tolerance of ±2.5V
