Note 1: All devices are 100% production tested at T A = +25°C and are guaranteed by design for T A = T MIN to T MAX , as specified.
Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse
Breakdown Voltage Tolerance ±[( ? V R / ? T)(max ? T)(V R )], where ? V R / ? T is the V R temperature coefficient, max ? T is the maxi-
mum difference in temperature from the reference point of +25°C to T MIN or T MAX , and V R is the reverse breakdown volt-
age. The total overtemperature tolerance for the different grades in the temperature range where max ? T = +65°C is shown
below:
A grade: ±0.75% = ±0.1% ±100ppm/°C 65°C
B grade: ±0.85% = ±0.2% ±100ppm/°C 65°C
C grade: ±1.15% = ±0.5% ±100ppm/°C 65°C
D grade: ±1.98% = ±1.0% ±150ppm/°C 65°C
The total over-temperature tolerance for the different grades in the extended temperature range where max ? T = +100°C is
shown below:
A grade: ±1.1% = ±0.1% ±100ppm/°C 100°C
B grade: ±1.2% = ±0.2% ±100ppm/°C 100°C
C grade: ±1.5% = ±0.5% ±100ppm/°C 100°C
D grade: ±2.5% = ±1.0% ±150ppm/°C 100°C
Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature reverse breakdown voltage tolerance of ±2.5V
0.75% = ±19mV.
Note 3: Guaranteed by design.
