The LIE-312 is a single-channel pyroelectric detector in a TO-39 housing with a 2.0 mm diameter lithium-tantalate element featuring a metal black coating, designed for infrared sensing in voltage mode with long time constant. It has a nominal 5.0 mm aperture, a thermal time constant of 200 ms, and an electrical time constant of 5 s. Voltage responsivity is at least 500 V/W at 10 Hz and 50 V/W at 100 Hz under 500 K blackbody radiation at 25 °C. Noise density is no more than 180 nV/√Hz at 10 Hz and 35 nV/√Hz at 100 Hz. Detectivity ranges from 1.6E+08 cm√Hz/W at 1 kHz to 8.0E+08 cm√Hz/W at 10 Hz. The offset voltage is nominally 0.4 to 1.5 V, with a maximum drain-source voltage of 18 V. Operating and storage temperature is -25 to +60 °C.
