MA4E2054B1-1146T

RF Diode Overview

The MA4E2054B1-1146T is a surface mount low barrier Schottky diode manufactured by MACOM Technology Solutions. It features two Schottky chips in a series pair configuration housed in an SOT-323 (Case Style 1146) plastic package. Designed for high-volume, low-cost detector and mixer applications, it operates within a temperature range of -65°C to +125°C. Key electrical specifications include a minimum breakdown voltage of 3.0 V at 10 µA reverse current, maximum reverse leakage currents of 100 nA at 1 V and 500 nA at 3 V, and a total capacitance of 0.3 pF maximum at 0 V bias. The device supports a forward current of 20 mA and a reverse voltage of 3 V.

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package style and plating configuration. Ensure that the procurement channel provides valid traceability for RoHS compliance status. Confirm that the delivered components match the specified SOT-323 form factor and series pair internal wiring before integration into production lines.

RF Diode Selection Notes

Select this component when a balanced mixer or voltage doubler circuit requires a compact surface mount solution. The series pair configuration eliminates the need for external discrete matching components typically required for single diodes. Consider the low capacitance and noise figure characteristics for high-frequency X-band operations where signal integrity is critical.

RF Diode Part Context

This part belongs to the MA4E2054 series of low barrier N-type silicon Schottky diodes. The 'B1' designation indicates the series pair configuration, while '1146' specifies the SOT-323 package style. Other variants in the series offer single elements or unconnected pairs in different packages such as SOT-23, SOD-323, and SC-79.

RF Diode Replacement Considerations

MA4E2054D1-1146T offers the same series pair configuration in the identical SOT-323 package but may differ in specific electrical tolerances or plating options. Verify pinout compatibility and parameter equivalence before substitution.
