RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The -TR1G suffix indicates tape and reel packaging containing 3000 devices per 7-inch reel. Confirm compliance with RoHS standards and ensure the supplier provides original manufacturer documentation to validate authenticity before purchase.

RF Diode Selection Notes

Select this component when a common cathode PIN diode configuration is required for RF switching. Ensure the design accommodates the 100 V peak inverse voltage rating. Consider the SOT-23 footprint dimensions during PCB layout. Verify that the 2.5 Ω series resistance meets the insertion loss requirements of the target application.

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, and dual switch modes. The HSMP-389F specifically denotes the common cathode variant within this family, optimized for general-purpose RF switching applications.

RF Diode Replacement Considerations

Direct replacements within the same series include HSMP-389B (Single), HSMP-389C (Series), and HSMP-389E (Common Anode). Verify pinout compatibility and electrical specifications before substituting. Other manufacturers may offer similar PIN diodes, but matching the carrier lifetime and capacitance values is critical for circuit performance.
