HSMS-2827-TR1

RF Diode Overview

The HSMS-2827-TR1 is a surface mount RF Schottky barrier diode manufactured by Broadcom Limited, belonging to the HSMS-282x series. It features a Ring Quad configuration housed in an SOT-143 package with marking code C7. The device is optimized for analog and digital applications, offering low series resistance and low forward voltage at all current levels. Key electrical specifications include a maximum breakdown voltage of 15 V, a typical forward voltage of 340 mV at 0.5 mA, and a maximum reverse leakage current of 100 nA at 10 V. The junction capacitance is typically 10 pF at 0 V reverse bias, with a dynamic resistance of 12 Ω at 5 mA. It operates within a temperature range of -65°C to +150°C.

RF Diode Feature Summary

• Ring Quad Configuration: Contains four matched Schottky diodes arranged in a ring topology, specifically designed for balanced mixer applications to suppress even-order harmonics.
• Low Turn-On Voltage: Features a low forward voltage drop (as low as 0.34 V at 1 mA), ensuring efficient signal detection and rectification with minimal power loss.
• High Match Consistency: Diodes are fabricated from adjacent sites on the wafer to ensure high degree of matching between units, critical for balanced circuit performance.
• Surface Mount Design: Available in compact SOT-143 packaging to save board space and facilitate automated assembly processes.

RF Diode Applications

• Double Balanced Mixers: Used in RF mixing circuits up to 6 GHz where harmonic suppression is required.
• Frequency Multipliers: Suitable for frequency multiplication applications due to fast switching characteristics.
• Sampling Circuits: Employed in high-speed sampling switches for analog-to-digital conversion interfaces.

RF Diode Procurement Notes

Verify the specific ordering suffix TR1 confirms tape and reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure the component matches the HSMS-282x family specifications for pinout and thermal characteristics during supply chain validation.

RF Diode Selection Notes

Select this component when a quad configuration is needed for balanced mixer topologies requiring common mode rejection. Compare against HSMS-282R if a planar crossover quad is preferred for simpler PCB layout. Evaluate thermal resistance requirements, as SOT-143 packages have different dissipation capabilities compared to SOT-363 variants.

RF Diode Part Context

This part belongs to the Agilent/Broadcom HSMS-282x family of surface mount RF Schottky diodes. The family offers various configurations including single, dual, and quad versions in SOT-23, SOT-143, SOT-323, and SOT-363 packages. The HSMS-2827 specifically provides the ring quad topology within the SOT-143 outline, distinguishing it from bridge or cross-over quads.

RF Diode Replacement Considerations

HSMS-282R serves as a functional alternative if a planar crossover quad configuration is acceptable for the design.
