RF Diode Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and datasheet revision against authorized distribution channels. Confirm RoHS compliance status and specific ordering suffixes match project requirements. Ensure storage conditions adhere to the specified temperature ranges to maintain device integrity prior to assembly.

RF Diode Selection Notes

Select this component when a single Schottky diode configuration is required for medium barrier applications. The SOT-23 package provides a compact footprint for space-constrained designs. Consider alternative series pair or unconnected pair configurations if circuit topology demands matched diode characteristics or differential signaling capabilities.

RF Diode Part Context

This component belongs to the MA4E1340 series of silicon medium barrier Schottky diodes manufactured by MACOM Technology Solutions. The series offers multiple package options including SOT-23, SOT-323, SC-79, and SOD-323. The 'A' designation indicates a single diode configuration, while 'B' denotes a series pair. The '1' suffix specifies the SOT-23 case style.

RF Diode Replacement Considerations

Direct substitutes within the same series include MA4E1340A1-1146T (SOT-323), MA4E1340A1-1141T (SOD-323), and MADS-001340-12790T (SC-79). These alternatives share identical electrical characteristics but differ in physical package dimensions and pinout orientation.
