HSMS-281L-TR2G

RF Diode Overview

The HSMS-281L-TR2G is a surface-mount RF Schottky barrier diode from the Broadcom HSMS-281x series, packaged in an SOT-363 (SC-70) configuration. It features an unconnected trio arrangement with three isolated diodes. Key electrical specifications include a breakdown voltage of 20 V, a maximum forward voltage of 400 mV at 1 mA, and a reverse leakage current of 35 nA at 20 V. The device exhibits a typical capacitance of 1.2 pF and dynamic resistance of 15 Ω at 5 mA. It operates within a junction temperature range of -65°C to +150°C and is supplied in a 13-inch tape and reel containing 10,000 units.

RF Diode Feature Summary

• Low flicker noise performance suitable for sensitive analog and digital applications
• Six-sigma quality level with low failure rate
• Wafer-matched dice ensure high degree of match for pairs and quads

RF Diode Applications

• RF detection circuits
• Mixer applications
• Low-noise signal processing

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm package type and quantity. The TR2 suffix indicates a 13-inch reel with 10,000 units. Ensure the G suffix is present for lead-free compliance. Confirm moisture sensitivity handling requirements before assembly.

RF Diode Selection Notes

Select this component when low flicker noise is critical compared to other Schottky families. The HSMS-281x offers lower noise than the HSMS-282x family while maintaining good current capacity. Choose the L variant specifically for unconnected trio configurations requiring three isolated diodes in a single package.

RF Diode Part Context

This part belongs to the HSMS-281x series of surface mount RF Schottky barrier diodes. The series provides various configurations including single, dual, and quad versions. The HSMS-281x family is characterized by hybrid Schottky technology designed to minimize 1/f noise for precision RF applications.

RF Diode Replacement Considerations

HSMS-281K-TR2G serves as a direct alternative offering a high isolation unconnected pair configuration instead of the trio.
