HSMS-286K-TR2G

RF Diode Overview

The HSMS-286K-TR2G is a surface mount microwave Schottky detector diode from the HSMS-286x family, manufactured by Broadcom Limited. It features a six-lead SOT-363 (SC-88) package containing two matched unconnected diodes configured for high isolation applications. The device operates within a frequency range of 915 MHz to 5.8 GHz and supports DC bias currents up to 5 µA. Key electrical specifications include a peak inverse voltage of 4.0 V, a typical junction capacitance of 0.25 pF at 0 V reverse bias, and a forward voltage ranging from 250 mV to 350 mV at 1.0 mA. Detection sensitivity reaches up to 50 mV/µW at 915 MHz.

RF Diode Feature Summary

• High Isolation Configuration: Grounded center leads provide up to 10 dB higher isolation compared to conventional pairs, minimizing RF coupling between detector and reference diodes in differential circuits.

RF Diode Applications

• Differential detector circuits requiring high isolation between signal paths
• RFID and RF Tag systems operating above 4 GHz
• Large signal detection and modulation

RF Diode Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for End-of-Life notifications prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements to prevent damage during assembly.

RF Diode Selection Notes

Select this part when high isolation between paired diodes is critical for circuit performance. The SOT-363 package offers better thermal conductivity than SOT-143 variants. Ensure design accommodates the specific pinout where leads 2 and 5 are grounded for optimal isolation performance.

RF Diode Part Context

This component belongs to the HSMS-286x series of DC biased detector diodes designed for frequencies from 915 MHz to 5.8 GHz. The 'K' suffix denotes the specific high-isolation unconnected pair configuration within the SOT-363 package, distinct from standard single or series pair configurations.

RF Diode Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and thermal requirements if considering alternative packages such as SOT-143 variants.
