HSMS-2814-TR1G

RF Diode Overview

The HSMS-2814-TR1G is a surface mount RF Schottky barrier diode from the HSMS-281x series, manufactured by Broadcom Limited. It features a common cathode configuration housed in an SOT-23 package with three leads. The device is optimized for low flicker noise applications and offers high voltage performance with a breakdown voltage of 20 V. Key electrical specifications include a maximum forward voltage of 400 mV at 1 mA forward current, a reverse leakage current of 200 nA at 20 V, and a capacitance of 1.2 pF at 0 V. The component supports a junction temperature up to 150°C and is available in tape and reel packaging.

RF Diode Feature Summary

• Features a common cathode configuration within a compact surface mount package
• Manufactured using techniques that ensure matched pairs and quads from adjacent wafer sites

RF Diode Applications

• Mixing circuits
• Signal detection
• Switching applications
• Sampling systems
• Clamping and wave shaping

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm the packaging quantity and lead-free status. The TR1 suffix indicates a 7-inch reel containing 3000 units. Ensure the G suffix is present if RoHS compliance is required. Confirm the manufacturer source matches Broadcom or its authorized predecessors to guarantee authenticity and traceability.

RF Diode Selection Notes

Select this component when low flicker noise is critical compared to other Schottky families. The HSMS-281x series provides lower 1/f noise than the HSMS-282x family while maintaining good RF characteristics. Choose the common cathode variant for differential or balanced circuit topologies requiring shared ground references.

RF Diode Part Context

This part belongs to the HSMS-281x series of surface mount RF Schottky barrier diodes. The series includes single, dual, and quad versions in various packages such as SOT-23, SOT-143, SOT-323, and SOT-363. The HSMS-281x family is specifically engineered to offer lower flicker noise than the standard HSMS-282x series, making it suitable for sensitive analog front-end designs.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMS-2814-BLK* for bulk packaging or HSMS-2814-TR2* for 13-inch reels. For different configurations, consider HSMS-2810 (Single), HSMS-2812 (Series), or HSMS-2813 (Common Anode). Verify pinout compatibility and thermal resistance differences when switching between SOT-23 and SOT-143 packages.
