MA4E2054D1-287T

RF Diode Overview

The MA4E2054D1-287T is a surface mount low barrier N-type silicon Schottky diode from the MA4E2054 series, manufactured by MACOM Technology Solutions. It features two Schottky chips in a series pair configuration within an SOT-23 (Case Style 287) plastic package. The device is designed for high-performance mixer and detector applications, offering low reverse leakage current (<500 nA at 3 V), low capacitance (0.30 pF max.), and low 1/F noise. Key electrical specifications include a minimum breakdown voltage of 3.0 V at 10 µA, a maximum dynamic resistance of 17 Ω at 10 mA forward current, and a forward voltage range of 250 mV to 350 mV at 1 mA. It supports an operating temperature range from -65°C to +125°C.

RF Diode Feature Summary

• Series pair configuration incorporating two Schottky chips for balanced mixer and detector voltage doubler circuits
• Low barrier design providing high detector sensitivity (-55 dBm TSS) and low noise figure (5.7 dB SSB at X-Band)
• Ultra-low total capacitance (0.30 pF max.) and low reverse leakage current for improved RF performance
• Lead-free construction compliant with RoHS directives and suitable for tape and reel processing

RF Diode Applications

• VSAT and DBS mixers
• Balanced mixer and detector voltage doubler circuits
• RF tag applications for identification and toll collection

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the package style and taping configuration. Ensure that the procurement channel provides original manufacturer packaging to maintain component integrity. Cross-reference the part number with the latest datasheet revision to confirm compliance with environmental standards such as RoHS. Confirm that the supplier can provide traceability documentation required for quality assurance processes.

RF Diode Selection Notes

Select this component when a series pair configuration is required for balanced mixer or voltage doubler topologies. The SOT-23 package offers a compact footprint suitable for space-constrained PCB layouts. Consider the low barrier characteristics for applications demanding high sensitivity at X-band frequencies. Evaluate the thermal management requirements given the specified operating temperature range and power dissipation limits under continuous wave conditions.

RF Diode Part Context

The MA4E2054D1-287T belongs to the MA4E2054 series of surface mount low barrier Schottky diodes. This series includes single element variants (MA4E2054A1, MA4E2054I) and unconnected pair configurations (MA4E2054B1). The D1 suffix specifically denotes the series pair wiring configuration housed in the SOT-23 package, distinguishing it from other pinouts and package styles within the same product family.

RF Diode Replacement Considerations

Direct substitutes within the MA4E2054 series include the MA4E2054B1-287T, which shares the SOT-23 package but utilizes an unconnected pair configuration rather than a series pair. Verify circuit compatibility if substituting between different internal chip arrangements.
