LM4041-1.2 Electrical Characteristics (Note 4)
Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C. The grades C and D designate initial Reverse Break-
down Voltage tolerance of ±0.5% and ± 1.0%, respectively.

Note 4. Specication for packaged product only.
Note 5. Typicals are at TJ = 25°C and represent most likely parametric norm.
Note 6. Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control (SQL)
methods.
Note 7. The boldface (over temperature limit for Reverse Breakdown Voltage Tolerance is dened as the room temperature Reverse Breakdown Volt-
age Tolerance ±[(ΔVR/ΔT)(65°C)(VR)]. ΔVR/ΔT is the VR temperature coefcient, 65°C is the temperature range from –40°C to the reference
point of 25°C, and VR is the reverse breakdown voltage. The total over temperature tolerance for the different grades follows:
C-grade: ±1.15% = ±0.5% ±100ppm/°C × 65°C
D-grade: ±1.98% = ±1.0% ±150ppm/°C × 65°C
Example: The C-grade LM4040-2.5 has an over temperature Reverse Breakdown Voltage tolerance of ±2.5 × 1.15% = ±29mV.
