The LM335 series are precision, easily-calibrated, integrated circuit temperature sensors. Operating as a 2-terminal zener, the LM335 has a breakdown voltage directly proportional to absolute temperature at +10 mV/°K. With less than 1W dynamic impedance the device operates over a current range of 400 μA to 5 mA with virtually no change in performance. When calibrated at 25°C the LM135 has typically less than 1°C error over a 100°C temperature range. Unlike other sensors the LM135 has a linear output.
The LM335 operates from −40°C to +100°C.

The LM135/LM235/LM335 are available packaged in hermetic TO-46 transistor packages while the LM335 is also available in plastic TO-92 packages.
