The MA4E2200 series are Silicon zero bias P-type
detector diodes assembled in low cost surface mount
plastic packages. They are designed for usage in a wide
variety of detector applications.
The MA4E2200 series of zero bias detector diodes
are available in the SOT-23 (case style 287) in series
pair configurations, SOD-323 (case style 1141),
SC-79 (1279) in a single configuration, and the SOT-143
(case style 1068) in a reverse unconnected pair configuration.
The part number consists of the base number
MA4E2200, followed by the wiring configuration (A,
B, D, E ), the package style (287, 1068, 1141) and a
“T” for tape and reel. The SC-79 part number is
These parts are offered with Sn/Pb plating, as well
as with 100 % matte Sn plating on the RoHs compliant
The small diode package size and moderate parasitics
make these parts attractive for Low Leakage
Limiters and RF Temperature Compensated Envelope
Detectors for RF ID Tags Applications up to 4 GHz.
