RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The BLKG suffix indicates bulk packaging containing 100 pieces per antistatic bag. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS requirements if applicable to your assembly process.

RF Diode Selection Notes

Select this component when low parasitic inductance is critical for high-frequency performance up to 3 GHz. The single diode configuration simplifies circuit design compared to multi-diode arrays. Verify that the 100 V breakdown voltage and thermal characteristics meet the system's power dissipation requirements.

RF Diode Part Context

This part belongs to the HSMP-389x series of surface mount RF PIN switch diodes. The 'T' designation specifically identifies the low inductance single diode variant within the series. Other variants in the series offer different configurations such as series pairs or common cathode arrangements.

RF Diode Replacement Considerations

Direct replacements must match the single diode configuration, 100 V breakdown voltage, and SOT-23 package. Check datasheets for equivalent low inductance specifications and ensure compatibility with existing PCB footprints.
