Reverse breakdown change with curren

All limits T_A = T_J = 25°C, unless otherwise specified. The grades C, D, and E designate initial reverse breakdown voltage tolerance of ±0.5%, ±1.0%, and ±2.0% respectively.

(1) Limits are 100% production tested at 25°C. Limits over temperature are made sure through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate AOQL.

(2) Typical values are at T_J = 25°C and represent most likely parametric norm.

(3) The over temperature limit for reverse breakdown voltage tolerance is defined as the room temperature reverse breakdown voltage tolerance ±[(ΔV_R↱ΔT)(max ΔT)(V_R)]. Where, ΔV_R/ΔT is the V_R temperature coefficient, max ΔT is the maximum difference in temperature from the reference point of 25 °C to T_MAX or T_MIN, and V_R is the reverse breakdown voltage. The total over-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% ±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
E-grade: ±2.98% = ±2.0% ±150ppm/°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% ±100ppm/°C × 100°C
C-grade: ±1.5% = ±0.5% ±100ppm/°C × 100°C
D-grade: ±2.5% = ±1.0% ±150ppm/°C × 100°C
E-grade: ±4.5% = ±2.0% ±150ppm/°C × 100°C
Therefore, as an example, the A-grade LM4041-NLM4041-N-Q1 1.2 has an over-temperature reverse breakdown voltage tolerance of ±1.2 V × 0.75% = ±9.2mV.

(4) Load regulation is measured on pulse basis from no load to the specified load current. Output 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.
