Description and Applications
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.
SC-79 (1279)
Configurations (Topviews)
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
MADS-002200-12790T.
These parts are offered with Sn/Pb plating, as well
as with 100 % matte Sn plating on the RoHs compliant part numbers.

The MADS-002200 in an SC-79 Package Style was evaluated in a detector circuit in which the
Schottky diode terminates a 50 Ohm transmission line on a duroid substrate. The SC-79 packaged
diode was attached to the terminal of a 3.5mm connector and the output voltage was measured
through a bias tee on a voltmeter. Matching was not attempted.
The voltage peak at 2 GHz is due to a resonance of the SC-79 package inductance with the diode junction capacitance. This condition results in higher RF voltage across the diode junction.
