Dual Diode - Series Pair (Tee) Configuration: 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? and 75? systems. These parts are offered with Sn/Pb plating, as well as with 100% matte Sn plating on the RoHS compliant part numbers. The MA4E1338 Series of Schottky diodes is available 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. 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, 8V Schottky Diodes are Useful in Detector, Limiter, Mixer, and Surge Protection Applications for Operating Frequency Bands from D.C. through 6 GHz.
