    Products Detail

    The series includes NPN silicon phototransistors (OP505, OP506, OP705) and a photodarlington (OP535). OP705 has an integrated base-emitter resistor for low light rejection. Devices come in blue-tinted T-1 (3mm) epoxy package. They offer variety of sensitivity ranges and receiving angles: narrow (20°) for OP505, OP535, OP705; wider for OP506; widest (90°) for OP505W and OP506W. Ideal for space-limited applications. 100% production tested with infrared light for correlation with GaAs and GaAIAs emitters.

    Key Features

    • Package: T-1 (3mm) epoxy, blue-tinted
