6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)(2)| MIN | MAX | UNIT | |
|---|---|---|---|
| Input voltage (survival) | −50 | 60 | V |
| Power dissipation(3) | Internally limited | ||
| Junction temperature, TJMAX | 150 | °C | |
| Storage temperature, Tstg | −65 | 150 | |
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, contact the TI Sales Office/ Distributors for availability and specifications.
(3) The maximum power dissipation is a function of TJ(MAX), RθJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) − TA) / RθJA. If this dissipation is exceeded, the die temperature can rise above the TJ(MAX) of 150°C, and the LM2936Q may go into thermal shutdown.
6.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V |
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. .
