HSMS-2860-TR2G

RF Diode Overview

The HSMS-2860-TR2G is a surface mount microwave Schottky detector diode from the HSMS-286x family, designed for operation between 915 MHz and 5.8 GHz. It features a single diode configuration in an SOT-23 package with a typical forward voltage of 250 mV (max 350 mV) at 1.0 mA and a junction capacitance of 0.30 pF at 0 V reverse bias and 1 MHz. The device offers high detection sensitivity, reaching up to 50 mV/µW at 915 MHz, and supports DC bias applications for large signal detection, modulation, RF-to-DC conversion, and voltage doubling.

RF Diode Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper handling procedures are followed due to electrostatic sensitivity. Review the latest product change notices for any updates to specifications or packaging details before finalizing procurement orders.

RF Diode Selection Notes

Select this component when designing detectors for frequencies above 4 GHz where small signal detection is required without DC bias. For lower frequencies such as 915 MHz, consider alternative series like HSMS-282x for better performance characteristics. Evaluate thermal resistance requirements carefully, as the SOT-23 package has higher thermal resistance compared to SOT-323 or SOT-363 variants. Ensure impedance matching networks are designed around the specific RF impedance curves provided in the datasheet for optimal sensitivity.

RF Diode Part Context

This part belongs to the HSMS-286x family of surface mount microwave Schottky detector diodes originally developed by Agilent Technologies and later manufactured by Broadcom Limited. The family includes various configurations such as single diodes, series pairs, common anode/cathode setups, and bridge quads in SOT-23, SOT-143, SOT-323, and SOT-363 packages. The HSMS-2860 specifically denotes the single diode variant in the SOT-23 package.

RF Diode Replacement Considerations

Direct functional substitutes within the same package include other single diode variants from the HSMS-286x family, though pinout compatibility must be verified. For different package types, the HSMS-286B serves as the single diode equivalent in the SOT-323 package. Cross-family replacements like the HSMS-282x may offer better performance at lower frequencies but require circuit redesign.
