HSMS-2700-TR1

RF Diode Overview

The HSMS-2700-TR1 is a high-performance Schottky diode designed for transient suppression and circuit protection. It features ultra-low series resistance of 0.65 Ω, enabling higher current handling capabilities compared to conventional RF diodes. The device operates in an SOT-23 package with a typical breakdown voltage of 15 V and a maximum DC forward current rating of 350 mA. Its picosecond switching speed (100 ps carrier lifetime) and low capacitance (6.7 pF at 0 V) minimize signal degradation during high-speed switching applications.

RF Diode Feature Summary

• Ultra-low series resistance optimizes current handling for protecting sensitive circuits against high-current transients on data lines.
• Picosecond switching response allows the device to react to noise spikes with rise times as fast as 1 ns.
• Low junction capacitance preserves waveshape integrity and minimizes signal loss in high-frequency designs.

RF Diode Applications

• Circuit protection for computer and RF designs requiring voltage clamping.
• High-speed switching applications involving digital data streams.
• Transient suppression on noisy data lines to prevent signal degradation.

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The -TR1 suffix indicates a 3,000-unit quantity on a 7-inch reel. Confirm lead-free status if required, as the datasheet notes that adding a 'G' character to the part number denotes the lead-free option. Ensure compatibility with standard surface-mount assembly processes for the SOT-23 outline.

RF Diode Selection Notes

Select this component when low series resistance is critical for managing high forward currents without thermal runaway. Compare the SOT-23 package's thermal resistance against the SOT-323 variant if higher steady-state current capacity is needed. Ensure the 15 V breakdown voltage meets the peak inverse voltage requirements of the target circuit environment.

RF Diode Part Context

This component belongs to the HSMS-270x family, which includes single diodes (HSMS-2700, HSMS-2702) and series pairs (HSMS-270B, HSMS-270C). The HSMS-2700 is the single-diode version housed in the SOT-23 package, distinct from the SOT-323 packaged HSMS-270B. The family shares similar SPICE parameters but differs in package thermal characteristics and current handling limits.

RF Diode Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other Avago HSMS-270x variants or HBAT-540x series diodes based on specific trade-offs between series resistance and junction capacitance.

RF Diode FAQ

How does the series resistance of the HSMS-2700 compare to other Schottky diodes?

The HSMS-2700 has a typical series resistance of 0.65 Ω, which is significantly lower than conventional RF Schottky diodes that may have resistances around 7.7 Ω. This low resistance prevents thermal runaway and maintains a low voltage limit during high current spikes.

What is the maximum steady-state forward current for the HSMS-2700?

The absolute maximum DC forward current for the HSMS-2700 in the SOT-23 package is 350 mA. Higher currents can be handled for short pulses less than one microsecond without impacting mean-time-to-failure.

Does the HSMS-2700 exhibit minority-carrier storage effects?

No. As a Schottky diode, current is carried only by majority carriers (electrons). This absence of minority-carrier charge storage results in a carrier lifetime of less than 100 ps, enabling extremely fast switching speeds.
