Description and Applications
The MA4E1338 series is a silicon medium barrier
Schottky diode suitable for use in mixer, detector
and limiter circuits. These diodes are also suitable
for usage in anti-parallel, shunt power surge
protection circuits for 50 and 75 systems.
The MA4E1338 Series of Schottky diodes is
available in the SOT-23 (case style 287), SOT-323
(case style 1146) , SC-79 (case style 1279) and the
SOD 323, (case style 1141) plastic package. These
packages are supplied on tape and reel for
automatic pick and place assembly and for surface
mount placement to circuit boards, as indicated by a
“T” to the P/N suffix.
SOD-323 (1141)
Configurations (Top View)
These Silicon Medium Barrier, 8 V Schottky Diodes
are useful in detector, limiter, mixer, and surge
protection applications for operating frequency
bands from DC through 6 GHz.
