Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.

Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse

Breakdown Voltage Tolerance ±[(∆VR/∆T)(max∆T)(VR)], where ∆VR/∆T is the VR temperature coefficient, max∆T is the max-

imum difference in temperature from the reference point of +25°C to TMIN or TMAX, and VR 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 x 65°C

B grade: ±0.85% = ±0.2% ±100ppm/°C x 65°C

C grade: ±1.15% = ±0.5% ±100ppm/°C x 65°C

D grade: ±1.98% = ±1.0% ±150ppm/°C x 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 x 100°C

B grade: ±1.2% = ±0.2% ±100ppm/°C x 100°C

C grade: ±1.5% = ±0.5% ±100ppm/°C x 100°C

D grade: ±2.5% = ±1.0% ±150ppm/°C x 100°C

Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature reverse breakdown voltage tolerance of ±2.5V

x 0.75% = ±19mV.

Note 3: Guaranteed by design.
