HSMS-286F-TR1G

RF Diode Overview

The HSMS-286F-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 and configured as a common cathode pair. The device operates within the UHF to C band frequency range of 915 MHz to 5.8 GHz. Key electrical specifications include a typical forward voltage of 250 mV minimum to 350 mV maximum at 1.0 mA, and a typical capacitance of 0.25 pF at 0 V reverse bias and 1 MHz. The absolute maximum ratings specify a peak inverse voltage of 4.0 V and a junction temperature limit of 150 °C.

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required tape and reel packaging configuration. Ensure compliance with RoHS directives if lead-free variants are mandated for the assembly process. Cross-reference the date code against current production status to avoid obsolete stock.

RF Diode Selection Notes

Select this component when a common cathode dual-diode configuration is required for differential or doubler topologies. The SOT-323 package provides superior thermal dissipation relative to SOT-23 alternatives. Evaluate the 0.25 pF capacitance and video resistance parameters against the target impedance matching network requirements for the specific operating frequency.

RF Diode Part Context

This part belongs to the HSMS-286x series of DC biased detector diodes designed for low-cost, high-volume designs. 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-286F specifically utilizes the SOT-323 form factor with a common cathode arrangement.

RF Diode Replacement Considerations

The HSMS-286B serves as a single diode alternative within the same package. For identical common cathode functionality, verify availability of other common cathode variants in the HSMS-286x family that match the SOT-323 outline and electrical tolerances.
