HSMS-281C-TR2G

RF Diode Overview

The HSMS-281C-TR2G is a surface mount RF Schottky barrier diode configured as a series pair within the HSMS-281x family. It features a low flicker noise profile and is available in lead-free packaging. The device operates with a maximum breakdown voltage of 20 V and a typical forward voltage of 400 mV at 1 mA. Reverse leakage current is limited to 35 nA at 20 V reverse bias, while junction capacitance measures 1.2 pF at 0 V. Dynamic resistance is specified at 15 ohms at 5 mA. It is supplied in a 13-inch tape and reel containing 10,000 units.

RF Diode Feature Summary

• Low flicker (1/f) noise performance for analog and digital applications
• Six-sigma quality level with low failure rate
• Surface mount packages including SOT-23 and SOT-143 configurations
• Lead-free option available

RF Diode Applications

• Analog signal processing circuits
• Digital switching applications
• RF mixer designs requiring low noise characteristics

RF Diode Procurement Notes

Verify the specific package outline required for the design, as the HSMS-281x series supports multiple configurations such as SOT-23 and SOT-143. Confirm that the 'TR2' suffix aligns with the intended 10,000-unit reel quantity. Ensure the lead-free designation matches environmental compliance requirements for the target assembly process.

RF Diode Selection Notes

Select this component when low flicker noise is critical compared to other Schottky families like the HSMS-282x. The series configuration suits applications requiring higher voltage handling than single diodes while maintaining matched characteristics. Verify thermal resistance limits against the expected operating temperature range of -65°C to 150°C.

RF Diode Part Context

This part belongs to the HSMS-281x series of surface mount RF Schottky barrier diodes manufactured by Broadcom Limited. The series provides various configurations including single, dual, and quad versions to offer designer flexibility. The manufacturing process ensures dice in pairs are taken from adjacent wafer sites for high matching accuracy.

RF Diode Replacement Considerations

HSMS-281C-TR1G serves as an alternative packaging option with a 3,000-unit reel quantity instead of 10,000.
