Limits are 100% production tested at 25°C. Limits over temperature are ensured through correlation using Statistical Quality Control

(SQC) methods. The limits are used to calculate AOQL.

The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse

Breakdown Voltage Tolerance ±[(

temperature tolerance for the different grades in the industrial temperature range where max

ΔT=65°C is shown below:

A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C

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

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

D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C

E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C

The total over-temperature tolerance for the different grades in the extended temperature range where max

ΔT = 100 °C is shown

below:

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

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

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

E-grade: ±4.5% = ±2.0% ±150 ppm/°C × 100°C

Therefore, as an example, the A-grade LM4041-N 1.2 has an over-temperature Reverse Breakdown Voltage tolerance of ±1.2V × 0.75%

= ±9.2 mV.

Load regulation is measured on pulse basis from no load to the specified load current. Ouput changes due to die temperature change

must be taken into account separately.-

(5)

Thermal hysteresis is defined as the difference in voltage measured at +25°C after cycling to temperature -40°C and the 25°C

measurement after cycling to temperature +125°C.
