Zero Bias Si Detector

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 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 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.
