  • Abstract
    A radiation-hardened, monolithic, silicon bipolar phototransistor has been developed and produced. Common emitter current gain at 2 mA collector current is 225 and remains above 140 after irradiation of 1 E13 n/sq cm or 1 Mrad(Si). Device photoresponse to 820 nm light decreases about 30% after 1 Mrad(Si) exposure and 55% after 1 E13 n/sq cm irradiation for typical input light levels. This phototransistor is ideal for applications requiring a radiation-hardened optocoupler
