RF Diode Procurement Notes

Verify the exact ordering suffix against official distributor catalogs to confirm the packaging format. The TR2G designation specifies a 10,000-unit count on a 13-inch reel. Ensure compatibility with standard SMT reflow profiles during assembly planning. Confirm lead finish and material specifications match design requirements before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a Common Anode PIN diode configuration is required for RF switching. The SOT-323 package offers a compact footprint suitable for space-constrained PCB layouts. Evaluate the 0.30 pF capacitance and 2.5 ohm series resistance against system impedance matching needs. Consider the 100V breakdown voltage for high-power signal handling capabilities.

RF Diode Part Context

This part belongs to the HSMP-389x series of surface mount RF PIN switch diodes manufactured by Broadcom Limited. The series includes various configurations such as single, series, dual switch mode, and unconnected trio arrangements. The HSMP-3893 specifically denotes the Common Anode variant within this family, sharing general reliability and thermal characteristics with other members of the series.

RF Diode Replacement Considerations

Direct replacements must maintain the Common Anode configuration and similar electrical parameters. Verify pinout compatibility for SOT-323 packages. Check datasheets for equivalent breakdown voltage and capacitance values to ensure circuit performance remains unaffected during substitution.
