HSMS-286L-TR1G

RF Diode Overview

The HSMS-286L-TR1G is a surface mount microwave Schottky detector diode from the HSMS-286x family, manufactured by Broadcom Limited. It is housed in an SOT-323 package with lead code 'TL', identifying it as an unconnected trio configuration containing three independent single diodes. The device operates within the 915 MHz to 5.8 GHz frequency range and features a peak inverse voltage of 4.0 V. Typical forward voltage ranges from 250 mV to 350 mV at 1.0 mA, with a typical junction capacitance of 0.25 pF at 0 V reverse bias and 1 MHz. The component supports a maximum junction temperature of 150°C and is designed for applications requiring matched diodes for consistent performance.

RF Diode Procurement Notes

Verify the specific ordering suffix TR1G corresponds to tape and reel packaging when sourcing. Confirm the manufacturer designation remains Broadcom Limited or Avago depending on the production era. Ensure compatibility with RoHS standards if required by the final assembly specifications.

RF Diode Selection Notes

Select this component when a triple-diode configuration is required without internal series or common connections. The SOT-323 package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance characteristics of the SOT-323 package for power dissipation requirements relative to larger SOT-363 alternatives.

RF Diode Part Context

This part belongs to the HSMS-286x series of DC biased detector diodes. The series includes various configurations such as single diodes, series pairs, and bridge quads in SOT-23, SOT-143, SOT-323, and SOT-363 packages. The HSMS-286L specifically utilizes the SOT-323 form factor with the TL marking code.

RF Diode Replacement Considerations

HSMS-286B-TR1G provides a single diode in the same SOT-323 package. HSMS-286C-TR1G offers a series pair configuration. For six-lead requirements, HSMS-286K-TR2G serves as a high-isolation alternative in the SOT-363 package.
