In one embodiment of the present invention, photocurrents induced in the collector-base junction of a transistor by ionizing radiation incident thereon are compensated by the photocurrent generated by a plurality of series-connected diodes. One feature of the invention includes the selection of the junction areas of the diodes relative to that of the transistor to obtain a predetermined potential at an electrode of the transistor during the incidence of the ionizing radiation.
