* The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-19500.
1. SCOPE
1.1 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.
* 1.2 Physical dimensions. See figure 1 (4N47, 4N47A, 4N48, 4N48A, 4N49, and 4N49A) (similar to TO-99), and
figure 2 (4N47U, 4N48U, 4N49U, 4N47BU, 4N48BU, and 4N49BU).
1.3 Maximum ratings
. Unless otherwise specified, maximum ratings apply to all case outlines, T
A
= +25°C.
