HSMS-2702-TR1

RF Diode Overview

The HSMS-2702-TR1 is a single Schottky diode from the HSMS-270x series, designed for transient suppression and high-speed switching. It features ultra-low series resistance (0.65 Ω typical) to handle higher forward currents without thermal runaway. The device operates with a maximum DC forward current of 350 mA and a peak surge current of 1.0 A. Key electrical specifications include a forward voltage of 550 mV at 100 mA, a breakdown voltage of 15 V, and a low capacitance of 6.7 pF. It is housed in an SOT-23 package.

RF Diode Feature Summary

• Ultra-low series resistance enables superior current handling capability for protecting sensitive circuit elements against high-current transients.
• Picosecond switching speed allows response to noise spikes with rise times as fast as 1 ns, preserving signal integrity.
• Low junction capacitance minimizes waveshape loss and prevents signal degradation in high-frequency applications.

RF Diode Applications

• Circuit protection and clamping for data lines carrying high-speed digital signals.
• Transient suppression in RF and computer designs requiring high-speed switching.
• Voltage clamping applications where low turn-on voltage and fast recovery are critical.

RF Diode Procurement Notes

Verify the specific ordering suffix to confirm packaging quantity and lead-free status. The TR1 suffix indicates a standard reel configuration. Confirm RoHS compliance requirements against the specific manufacturing date code, as lead-free options may carry a distinct G suffix. Ensure the component meets the required ambient temperature ratings for the intended application environment.

RF Diode Selection Notes

Select this component when low series resistance is prioritized over minimal capacitance for high-current transient protection. Compare thermal resistance characteristics against alternative packages like SOT-323 if higher steady-state current capacity is required. Ensure the 15 V breakdown voltage aligns with the system's peak inverse voltage limits to prevent device failure during transient events.

RF Diode Part Context

This part belongs to the HSMS-270x family of high-performance Schottky diodes manufactured by Broadcom Limited. The series includes variants such as HSMS-2700, HSMS-270B, and HSMS-270C, which differ primarily in package type and current handling capabilities. The HSMS-2702 specifically utilizes the SOT-23 package for single-diode configurations.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMS-2700-TR1, which shares identical electrical specifications but may have different marking codes. For higher current handling in the same footprint, consider the HSMS-270B series, though it requires verification of package compatibility and thermal performance differences between SOT-23 and SOT-323.
