HSMS-2815-TR2G

RF Diode Overview

The HSMS-2815-TR2G is a surface-mount RF Schottky barrier diode from the Broadcom Limited HSMS-281x series, packaged in SOT-23. It features an unconnected pair configuration with two isolated diodes. Key electrical specifications include a maximum breakdown voltage of 20V and a typical forward voltage of 400mV at 1mA forward current. The device exhibits low flicker noise and a typical capacitance of 1.2pF at 0V reverse bias and 1MHz frequency. Maximum dynamic resistance is specified at 15 ohms at 5mA forward current. The component supports a junction temperature up to 150°C and is supplied in tape and reel packaging.

RF Diode Feature Summary

• Low flicker (1/f) noise performance suitable for sensitive analog and digital applications
• Six-sigma quality level ensuring high reliability and low failure rates
• Tight matching characteristics between paired diodes for balanced circuit designs

RF Diode Applications

• RF mixer circuits requiring low noise figure
• Analog signal processing and detection stages
• Digital switching applications with low capacitance requirements

RF Diode Procurement Notes

Verify the specific ordering suffix TR2G indicates a 10,000-unit tape and reel quantity with lead-free compliance. Confirm the manufacturer designation matches Broadcom Limited or its predecessor entities as documented in official datasheets. Ensure the package marking code B5 corresponds to the unconnected pair configuration before integration into production lines.

RF Diode Selection Notes

Select this component when low flicker noise is critical compared to standard Schottky alternatives. The unconnected pair configuration allows for differential signaling or dual-diode topologies within a single footprint. Compare SPICE parameters such as series resistance and junction capacitance against other HSMS-281x variants like the single or quad versions to ensure optimal circuit performance.

RF Diode Part Context

This part belongs to the HSMS-281x family of surface mount RF Schottky diodes designed by Agilent Technologies, now managed by Broadcom Limited. The series offers various configurations including single, series, common anode, common cathode, and quad arrangements. The HSMS-2815 specifically provides an unconnected pair, distinguishing it from other members of the family that share internal connections.

RF Diode Replacement Considerations

Direct substitutes within the same family include HSMS-2810 for a single diode or HSMS-2817/HSMS-2818 for quad configurations if pinout compatibility allows. Verify that alternative parts maintain similar low flicker noise characteristics and package dimensions for seamless replacement in existing PCB layouts.
