OPB70AWZ through OPB70HWZ
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) For OPB703, OPB704 and OPB705, derate linearly 1.67 mW/° C above 25° C.
(3) For OPB703WZ, OPB704WZ, OPB705WZ and OPB70BWZ, derate linearly 1.82 mW/° C above 25° C.
(4) The distance from the assembly face to the reflective surface is d.
(5) Crosstalk (I
CX
) is the collector current measured with the indicated current in the input diode and with no reflecting surface.
(6) Measured using Eastman Kodak neutral white test card with 90% diffuse reflectance as a reflecting surface. Reference: Eastman
Kodak, Catalog # E 152 7795.
(7) All parameters tested using pulse techniques.
