PRELIMINARY INFORMATION
TCN4041
ELECTRICAL CHARACTERISTICS (Cont.): Boldface type specifications apply for TA = TJ = TMIN to TMAX. All other
specifications; TA = TJ = 25°C. The grades C, D, and E designate initial
Reverse Breakdown Voltage tolerances of ±0.5%, ±1.0%, and ±2.0%,
respectively.

NOTES: 4. Typicals are at TJ = 25°C and represent most likely parametric norm.
5. Limits are 100% production tested at 25°C.
6. The boldface (over-temperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown
Voltage Tolerance ±[(∆VR/∆T)(65°C)(VR)]. ∆VR/∆T is the VR temperature coefficient, 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 is shown
below:
C-grade: ±1.15% = ±0.5% ±100ppm/°C x 65°C
D-grade: ±1.98% = ±1.0% ±150ppm/°C x 65°C
E-grade: ±2.98% = ±2.0% ±150ppm/°C x 65°C
7. When VOUT ≤ 1.6V, the TCN4041-ADJ in the SOT-23B package must operate at reduced IR. This is caused by the series resistance of the
die attach between the die (-) output and the package (-) output pin. See the Output Saturation (SOT23-B only) curve in the Typical
Characteristics section.
8. Reference voltage and temperature coefficient will change with output voltage. See Typical Characteristics curves.
