Description and Applications
The MA4E1340 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 MA4E1340 Series of Schottky diodes is available 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 package. These 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, 70 V Schottky Diodes
are Useful in Detector, Limiter, Mixer, and Surge
Protection Applications for Operating Frequency
Bands from DC through 6 GHz.
