LM4041-N/LM4041-N-Q1 1.2 Electrical Characteristics (Industrial Temperature Range)
Boldface limits apply for TA = TJ = TMINto TMAX; all other limits TA = TJ = 25°C. The grades C, D and E designate initial
Reverse Breakdown Voltage tolerances of ±0.5%, ±1.0% and ±2.0%, respectively.

(1) Typicals are at TJ = 25°C and represent most likely parametric norm.
(2) 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.
(3) The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse
Breakdown Voltage Tolerance ±[(ΔVR↱ΔT)(max ΔT)(VR)]. Where, ΔVR/ΔT is the VR temperature coefficient, maxΔT is the maximum
difference in temperature from the reference point of 25 °C to T MAX or TMIN, and VR is the reverse breakdown voltage. The total over-
temperature tolerance for the different grades in the industrial temperature range where maxΔT=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.
(4) 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.
