HSMS-286K-TR1G

RF Diode Overview

The HSMS-286K-TR1G is a surface mount microwave Schottky detector diode from the HSMS-286x family, manufactured by Broadcom Limited. It is housed in a SOT-363 package and optimized for operation between 915 MHz and 5.8 GHz. The device features high detection sensitivity of up to 50 mV/µW at 915 MHz, 35 mV/µW at 2.45 GHz, and 25 mV/µW at 5.80 GHz. It provides up to 10 dB higher isolation compared to standard configurations due to grounded center leads. Electrical specifications include a typical forward voltage of 250 mV minimum and 350 mV maximum, with a capacitance of 0.25 pF at 0 V reverse bias and 1 MHz frequency.

RF Diode Feature Summary

• High isolation configuration achieved through grounded center leads
• Matched diodes sourced from adjacent wafer sites for consistent performance
• Enhanced thermal conductivity via copper leadframe design
• Miniature SOT-363 package footprint for board space savings

RF Diode Applications

• RFID and RF Tag applications
• Large signal detection
• Modulation circuits
• RF to DC conversion
• Voltage doubling circuits

RF Diode Procurement Notes

Verify component authenticity against official datasheets. Confirm package marking codes match the specific K configuration for high isolation. Ensure handling procedures account for electrostatic sensitivity as specified in manufacturer guidelines.

RF Diode Selection Notes

Select this variant when differential detector circuits require high isolation between reference and detector diodes. The grounded center leads reduce RF coupling errors. Verify thermal resistance requirements align with the SOT-363 package characteristics for power dissipation limits.

RF Diode Part Context

This component belongs to the HSMS-286x series of DC biased detector diodes. The 'K' suffix denotes the specific six-lead SOT-363 configuration with grounded center leads for high isolation. The 'TR1G' indicates tape and reel packaging and lead-free compliance.

RF Diode Replacement Considerations

HSMS-286B-TR1G offers single diode functionality in SOT-323. HSMS-286C-TR1G provides series pair configuration. Standard HSMS-2865 serves as a conventional differential detector without the enhanced isolation features of the K variant.
