6.1 Absolute Maximum Ratings (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) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating the device beyond its specified operating ratings.
(2) If Military/Aerospace specified devices are required, please 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 LM2936 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. .
