HSMS-270B-TR1

RF Diode Overview

The HSMS-270B-TR1 is a single Schottky diode in the HSMS-270x series, packaged in SOT-323 (SC-70). It features a forward voltage of 550 mV at 100 mA and a breakdown voltage of 15 V. The device exhibits low capacitance of 6.7 pF and series resistance of 0.65 Ω. It supports a DC forward current of 750 mA and peak surge current of 1 A. Operating temperature ranges from -65°C to +150°C with total power dissipation of 825 mW.

RF Diode Feature Summary

• Ultra-low series resistance enables high current handling for transient suppression.
• Picosecond switching speed allows response to noise spikes with rise times as fast as 1 ns.
• Low capacitance minimizes waveshape loss and signal degradation.

RF Diode Applications

• Circuit protection against higher current transients on data lines.
• High-speed switching applications requiring circuit preservation.
• Voltage clamping and wave shaping in RF and computer designs.

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging quantity and lead-free status. The TR1 suffix indicates a 3,000-unit reel. Confirm RoHS compliance requirements if applicable, noting that lead-free versions typically carry a 'G' suffix. Ensure the component matches the required SOT-323 package dimensions for PCB layout compatibility.

RF Diode Selection Notes

Select this component when high current handling capability is critical for transient suppression. The SOT-323 package offers lower thermal resistance compared to SOT-23 variants, supporting higher steady-state currents. Consider the 15 V breakdown voltage limit and 6.7 pF capacitance for signal integrity in high-frequency digital or RF circuits.

RF Diode Part Context

This part belongs to the HSMS-270x family of high-performance Schottky diodes designed for transient suppression. The series includes single configurations like the HSMS-270B and matched pairs such as the HSMS-2702. These devices are optimized for preserving circuit waveforms through ultra-low series resistance and fast switching characteristics.

RF Diode Replacement Considerations

Direct pin-compatible substitutes within the same series include HSMS-270B-BLK (bulk) or HSMS-270B-TR2 (10,000 reel). For SOT-23 packages, consider HSMS-2700 or HSMS-2702, though thermal performance differs due to package variations.
