HSMS-286P-TR1G

RF Diode Overview

The HSMS-286P-TR1G is a surface mount microwave Schottky detector diode from the HSMS-286x series, manufactured by Broadcom Limited. It features a bridge quad configuration within a SOT-363 (SC-70) package with six leads. The device is optimized for operation between 915 MHz and 5.8 GHz, serving applications such as RF/ID tags, large signal detection, modulation, and voltage doubling. Key electrical specifications include a typical forward voltage of 250 mV to 350 mV at 1.0 mA and a typical capacitance of 0.25 pF at 0 V reverse bias. The component supports a peak inverse voltage of 4.0 V and operates within a temperature range of -65°C to +150°C.

RF Diode Feature Summary

• Bridge quad configuration provides four matched diodes in a single compact surface mount package.
• High detection sensitivity across UHF and microwave frequencies up to 5.8 GHz.
• SOT-363 package utilizes copper leadframe for superior thermal conductivity compared to alloy alternatives.
• Diodes are sourced from adjacent wafer sites to ensure consistent forward voltage matching.

RF Diode Applications

• RF/ID and RFID tag power harvesting circuits
• Voltage doubler configurations for low-power DC generation
• Large signal detection and modulation demodulation
• Differential detector circuits requiring high isolation

RF Diode Procurement Notes

Verify the specific ordering suffix TR1G to confirm tape and reel packaging quantities. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure ESD handling precautions are observed during assembly due to the sensitivity of Schottky junctions.

RF Diode Selection Notes

Select this part when a bridge rectifier topology is required for voltage doubling or differential detection in a minimal footprint. The SOT-363 package offers better thermal dissipation than SOT-23 variants. Verify that the 0.25 pF capacitance meets the impedance matching requirements for the target frequency band.

RF Diode Part Context

This component belongs to the HSMS-286x family of surface mount microwave Schottky detector diodes. The 'P' designation specifically identifies the bridge quad configuration within the SOT-363 package. Other family members include single diodes, series pairs, and common anode/cathode configurations in SOT-23, SOT-143, and SOT-323 packages.
