(IR = 100µA, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS
Wideband Noise eN IR = 100μA, 10Hz ≤ f ≤ 10kHz 20 μVRMS Reverse Breakdown Voltage ΔV Long-Term Stability R T = 1000h, IR = 100μA 120 ppm
Note 1:
All devices are 100% production tested at +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Note 2:
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 TMIN or TMAX, and VR is the reverse breakdown voltage. The total overtemperature tolerance for the different grades in the temperature range where maxΔT = +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 The total overtemperature tolerance for the different grades in the extended temperature range where maxΔT = +100°C is shown below: A grade: ±1.1% = ±0.1% ±100ppm/°C ✕ 100°C 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 Therefore, as an example, the A-grade LM4041-1.2 has an overtemperature reverse breakdown voltage tolerance of ±2.5V x 0.75% = ±19mV.
Note 3:
Guaranteed by design.
