matched junctions minimize variation in capacitance,
forward voltage and dynamic resistance within the
four diodes in the quad. They are offered in low, medium
and high barrier heights. These diodes are available
in a small profile surface mount package SOT-143
(ODS-1068). They are available in tape and reel for
automatic pick and place assembly.
