Exceeding the absolute maximum ratings may damage the device. 2. The device is not guaranteed to function outside its operating ratings. 3. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (maximum junction temperature), ƟJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDMAX = (TJMAX – TA)/ ƟJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041, TJMAX = 125°C and the typical thermal resistance, when board-mounted, is 326°C/W for the SOT-23 package. 4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5k Ω in series with 100pF. The machine model is a 200pF capacitor discharged directly into each pin. 5. Specification for packaged product only. 6. The boldface (overtemperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance ±[( ΔV R/ΔT)(65°C)(VR)]. ΔVR/ΔT 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 overtemperature tolerance for the different grades follows: a. C-grade: ±1.15% = ±0.5% ±100ppm/°C × 65°C b. D-grade: ±1.98% = ±1.0% ±150ppm/°C × 65°C Example: The C-grade LM4040-2.5 has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5 × 1.15% = ±29mV. |
