scope:
This specification covers the performance requirements for solid state optically coupled isolators in which a gallium aluminum arsenide diode light source is optically coupled to a silicon NPN phototransistor. Four levels of product assurance are provided for each type as specified in MIL-PRF-19500.
See figure 1 (4N47, 4N47A, 4N48, 4N48A, 4N49, and 4N49A)(similar to TO-99); see figure 2 (4N47U, 4N48U, and 4N49U).
