The grades A and B designate initial Reverse Breakdown Voltage tolerances of ±0.1% and ±0.2%, respectively. PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1) UNIT (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. ZR Reverse Dynamic Impedance IR = 1 mA, f = 120 Hz, IAC = 0.1 IR 0.5 1 Ω eN Wideband Noise IR = 100 μA 10 Hz ≤ f ≤ 10 kHz 80 μVrms ΔVR Reverse Breakdown Voltage Long Term Stability t = 1000 hrs T = 25°C ±0.1°C IR = 100 μA 120 ppm VHYST Thermal Hysteresis(5) ΔT = −40°C to 125°C 0.08% (1) 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. (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. 6.15 Electrical Characteristics: 4.1-V LM4040-N VR Tolerance Grades 'C' and 'D'; Temperature Grade 'I' all other limits TA = TJ = 25°C. The grades C and D designate initial Reverse Breakdown Voltage tolerances of ±0.5% and ±1%, respectively.
