HSMS-280P-TR1G Equivalent & Substitute Parts

Part Overview

The HSMS-280P-TR1G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 2-pair series connection rated for 70V peak reverse voltage and 1A maximum current in a 6-TSSOP (SOT-363) package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across critical RF parameters while accommodating modern packaging and availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSMS-280P-TR1G is determined by the following critical electrical parameters:

• Voltage Rating: Peak reverse voltage must equal or exceed 70V
• Current Capacity: Maximum current rating must support the application requirement
• Capacitance Characteristics: Capacitance at 0V, 1MHz must be compatible with RF circuit performance
• Diode Configuration: Schottky diode type with appropriate internal connection topology
• Package Compatibility: Physical form factor must accommodate existing PCB layouts or allow for minor redesign

The MADS-001340-12790T from MACOM Technology Solutions is identified as a manufacturer-recommended substitute. While this part differs in configuration (single diode versus 2-pair series) and current rating (200mA versus 1A), it maintains the critical voltage and capacitance specifications required for RF applications at 70V operation.

Parameter Comparison

Engineering Selection Recommendations

The MADS-001340-12790T is the manufacturer-recommended substitute for the obsolete HSMS-280P-TR1G. Both components share identical voltage ratings (70V) and capacitance specifications (2pF @ 0V, 1MHz), which are the primary determinants of RF circuit performance in this application category.

Key considerations for selection:

• Product Status: The MADS-001340-12790T carries active product status with established supply chain availability, whereas the HSMS-280P-TR1G is obsolete.
• Current Rating Differential: The substitute part is rated for 200mA maximum current compared to 1A for the original. Applications requiring current levels above 200mA must be re-evaluated for circuit topology or alternative solutions.
• Package Transition: Migration from SOT-363 to SC-79 or SOD-523 packaging requires PCB layout modification.
• Compliance: Both parts maintain EAR99 export classification and MSL-1 moisture sensitivity rating, ensuring regulatory and handling consistency.
• Temperature Operating Range: The substitute specifies -55°C to 125°C, whereas the original lists 150°C maximum junction temperature. Thermal design review is required for high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the MADS-001340-12790T directly replace the HSMS-280P-TR1G without circuit modification?

A: Direct replacement requires evaluation of current requirements. The substitute is rated for 200mA maximum versus 1A for the original. If circuit current demands exceed 200mA, alternative solutions must be identified. Package differences (SOT-363 to SC-79/SOD-523) necessitate PCB layout changes.

Q: Are the RF characteristics equivalent between these parts?

A: Yes, for RF applications. Both components maintain 70V peak reverse voltage and 2pF capacitance at 0V, 1MHz, which are the primary RF performance parameters. These specifications ensure functional equivalence in RF circuit operation.

Q: What is the impact of the diode configuration difference (2-pair series versus single)?

A: The original HSMS-280P-TR1G uses a 2-pair series configuration, while the MADS-001340-12790T is a single diode. This affects internal circuit topology and current handling. Circuit redesign may be necessary to accommodate the configuration change.

Q: Are there moisture sensitivity or handling differences?

A: No. Both parts carry MSL-1 (Unlimited) classification, indicating identical moisture sensitivity levels and handling requirements.

Q: What compliance certifications apply to both parts?

A: Both components are classified as EAR99 under export control regulations and are REACH unaffected, ensuring consistent compliance status for supply chain and regulatory purposes.
