Description
The MA4E1339 series is a silicon, medium barrier Schottky
diode suitable for use in mixer or detector circuits.
Applications
The MA4E1339 family of silicon Schottky diodes may be
used in mixer or detector circuits. The MA4E1339A-287T,
MA4E1339A-1146T, and MA4E1339A-1141T are suitable
for use in single ended mixers or single diode detectors.
The MA4E1339B-287T and MA4E1339B-1146T are
suitable for use in single balanced mixers or voltage doubler
detectors. The MA4E1339E-1068T may be used in
temperature compensated detectors, single balanced mixers
or double balanced mixers.
The MA4E1339 series of Schottky diodes is available in the
SOT-23 (case style 287), the SOT-143 (case style 1068),
the SOT-323 (case style 1146) and the SOD-323 (case style
1141) packages. These packages are supplied on tape and
reel for automatic pick and place assembly on surface
mount circuit boards, as indicated by a “T” to the case style
suffix.
