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) , SC-79
(case style 1279) and the SOD 323, (case style
1141) plastic package. The se packages are supplied
on tape and reel for automatic pick and place as-
sembly and for surface 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.
