The grades C, D and E designate initial Reverse Breakdown Voltage tolerances of ±0.5%, ±1% and ±2%, respectively.

Limits over temperature are ensured through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate AOQL. (2) Typicals are at TJ = 25°C and represent most likely parametric norm. (3) The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance ±[( ΔVR/ΔT)(maxΔT)(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 MIN or TMAX, and VR is the reverse breakdown voltage. The total overtemperature 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 overtemperature tolerance for the different grades in the extended temperature range where max ΔT = 100 °C is shown below: C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C Therefore, as an example, the A-grade 2.5-V LM4040-N has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5V × 0.75% = ±19 mV. (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. 10 Submit Documentation Feedback Copyright © 2000–2015, Texas Instruments Incorporated Product Folder Links: LM4040-N LM4040-N-Q1 |
