MA4E2054A1-287T

RF Diode Overview

The MA4E2054A1-287T is a single-element, low barrier N-type silicon Schottky diode manufactured by MACOM Technology Solutions. It is housed in an SOT-23 (Case Style 287) surface mount plastic package and supplied in tape and reel format. The device is designed for high-performance mixer and detector applications, featuring a minimum breakdown voltage of 3.0 V at 10 µA reverse current. Key electrical specifications include a maximum total capacitance of 0.30 pF at 0 V bias and a dynamic resistance of 17 Ω maximum at 10 mA forward current. It operates within a temperature range of -65°C to +125°C.

RF Diode Feature Summary

• Low barrier design optimized for high-volume, low-cost detector and mixer applications
• Single element configuration suitable for single-ended mixer and detector circuits
• RoHS compliant with lead-free construction and 260°C reflow capability

RF Diode Applications

• VSAT and DBS mixers
• RF tag applications for identification and toll collection
• High performance detector diodes

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package style and taping configuration. Ensure that the component meets all applicable RoHS directives and environmental compliance standards required for the target assembly process before finalizing procurement orders.

RF Diode Selection Notes

Select this component for designs requiring a single Schottky diode in an SOT-23 package. Consider the 0.30 pF maximum capacitance and 3.0 V minimum breakdown voltage when designing RF front-ends. Verify thermal management requirements as power dissipation must be derated linearly to zero watts at 125°C case temperature.

RF Diode Part Context

This part belongs to the MA4E2054 series of surface mount low barrier Schottky diodes. The series includes various configurations such as single elements, series pairs, and unconnected pairs across multiple package styles including SOT-23, SOT-323, SOD-323, and SC-79. The 'A1' designation specifically indicates the single element configuration in the SOT-23 package.

RF Diode Replacement Considerations

Other parts in the MA4E2054 series may serve as alternatives depending on the required circuit topology. For balanced mixer or voltage doubler circuits, consider the series pair configurations such as MA4E2054B1-287T or MA4E2054D1-287T. Single-ended applications can utilize other single-element variants like MA4E20541-1141T if package compatibility allows.
