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 Ω and 75 Ω systems.
These parts are offered with Sn/Pb plating, as well
as with 100 % matte Sn plating on the RoHS compli-
ant part numbers.
The MA4E1338 Series of Schottky diodes is avail-
able in the SOT-23 ( case style 287 ), SOT-143
( case style 1068 ), SOT-323 ( case style 1146 )
and the SOD 323, ( case style 1141 ) plastic pack-
age. These packages are supplied on tape and reel
for automatic pick and place assembly and for sur-
face mount placement to circuit boards, as indicated
by a “T” to the P/N suffix.
These Silicon Medium Barrier, 8 V Schottky Diodes
are Useful in Detector, Limiter, Mixer, and Surge
Protection Applications for Operating Frequency
Bands from D.C. through 6 GHz.
