6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)(3)(2)(4)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Reverse Current | 15 | mA | ||
| Forward Current | 10 | mA | ||
| Storage temperature, Tstg | 8-Pin SOIC Package | −65 | 150 | °C |
| TO / TO-92 Package | −60 | 150 | °C | |
(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, please contact the TI Sales Office/Distributors for availability and specifications.
(3) Refer to RETS135H for military specifications.
(4) Soldering process must comply with the Reflow Temperature Profile specifications. Refer to http://www.ti.com/packaging.
6.2 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)| MIN | NOM | MAX | UNIT | |||
|---|---|---|---|---|---|---|
| Specified Temperature | LM135, LM135A | Continuous (TMIN ≤ TA ≤ TMAX) | −55 | 150 | °C | |
| Intermittent (1) | 150 | 200 | ||||
| LM235, LM235A | Continuous (TMIN ≤ TA ≤ TMAX) | −40 | 125 | °C | ||
| Intermittent (1) | 125 | 150 | ||||
| LM335, LM335A | Continuous (TMIN ≤ TA ≤ TMAX) | −40 | 100 | °C | ||
| Intermittent (1) | 100 | 125 | ||||
| Forward Current | 0.4 | 1 | 5 | mA | ||
(1) Continuous operation at these temperatures for 5,000 hours for LP package may decrease life expectancy of the device.
