Extrinsic photodetectors with implanted low ohmic contacts are used in ISOPHOT, which is one of the four focal plane instruments of the Infrared Space Observatory (ISO). If operated under the low temperature and low background conditions of ISO, such detectors show a highly nonlinear transient response to step changes of infrared illumination. For the Si:Ga detector arrays in PHT-S, the spectrometer in ISOPHOT, we are able to describe accurately the nonlinear photoresponse by a simple analytical function of time. Based on the theory, fundamental detector constants characterizing the dynamic behavior of such detectors can be extracted from experimental data. This allows the prediction of the steady state signals of short time measurements that have not stabilized after an illumination change. Results are presented on the dynamic effects of step-like flux changes and on the observed nonstationary injection of carriers due to temperature variations of the detector. The optimization of the in-orbit observation strategy is discussed using theory and experimental results.
