(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

(2)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),

θJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any

temperature is PDmax = (TJmax − TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4041-N,

TJmax = 125°C, and the typical thermal resistance (θJA), when board mounted, is 326°C/W for the SOT-23 package, 415°C/W for the

SC70 package and 180°C/W with 0.4

″ lead length and 170°C/W with 0.125″ lead length for the TO-92 package.

LM4041-N 1.2 Electrical Characteristics (Industrial Temperature Range)

Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25°C. The grades A and B designate initial

Reverse Breakdown Voltage tolerances of ±0.1% and ±0.2%, respectively.

Typicals are at TJ = 25°C and represent most likely parametric norm.

(2)

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.

(3)

The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse

Breakdown Voltage Tolerance ±[(

ΔVR↱ΔT)(max ΔT)(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 MAX or TMIN, and VR 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% ±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 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% ±100 ppm/°C × 100°C

C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C

D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C

E-grade: ±4.5% = ±2.0% ±150 ppm/°C × 100°C

Therefore, as an example, the A-grade LM4041-N 1.2 has an over-temperature Reverse Breakdown Voltage tolerance of ±1.2V × 0.75%

= ±9.2 mV.
