Features
• RF & Microwave Medium Barrier Silicon
20 V Schottky Diode
• Available as Single Diode, Series Pai r o r
Unconnected Pair Configurations.
• Low Profile Surface Mount Plastic Packages
• Lead Free (RoHS Compliant) Equivalents Avail-
able With 260 Deg. C Reflow Capability
Description and Applications
The MA4E1339 series is a silicon medium barrier
Schottky diode suitable for use in mixer, detector
and limiter circuits. These diodes are also usable 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 compliant
part numbers.
The MA4E1339 Series of Schottky diodes is avail-
able in the SOT-23 ( case style 287 ), SOT-143
( case style 1068 ), SOT-323 ( case style 1146 ),
SOD 323 (case style 1141) and the SC-79 ( case
style 1279 ).
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.
These Silicon Medium Barrier, 20 V Schottky Diodes
are Useful in Detector, Limiter, Mixer, and Surge
Protection Applications for Operating Frequency
Bands from D.C. through 6 GHz.
