HSMS-280F-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-280F-TR2G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1 Pair Common Cathode device in SOT-323 surface mount packaging. This component is rated for 70V peak reverse voltage with 1A maximum current capability and operates at junction temperatures up to 150°C. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-280F-TR2G is determined by the following critical parameters:

• Diode Configuration: Must be 1 Pair Common Cathode Schottky technology
• Package Type: Must be SC-70 or SOT-323 surface mount
• Voltage Rating: Must support minimum 70V peak reverse voltage
• Current Capability: Must support application requirements within rated specifications
• Operating Temperature: Must support 150°C junction temperature operation
• Mounting Type: Must be surface mount compatible

The substitute parts listed below meet these electrical and mechanical requirements while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Substitute: BAS70-05W,115 or BAS70-05W,135

Both BAS70-05W variants are recommended as direct substitutes for the HSMS-280F-TR2G. These parts maintain the 70V voltage rating and 150°C maximum junction temperature of the original component. Both are manufactured by Nexperia USA Inc. with active product status, ROHS3 compliance, and established supply chain availability. The variants differ only in packaging reel configuration (,115 vs ,135) and do not affect electrical performance.

Secondary Substitute: 1PS70SB85,115

The 1PS70SB85,115 is suitable only for applications where current requirements do not exceed 30mA per diode. This part has a reduced voltage rating of 15V and maximum junction temperature of 125°C, making it incompatible with designs requiring the full 70V rating or 150°C thermal performance of the original HSMS-280F-TR2G.

All substitute parts maintain SOT-323 packaging compatibility and MSL Level 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB85,115 replace the HSMS-280F-TR2G in all applications?

A: No. The 1PS70SB85,115 has a maximum reverse voltage rating of 15V compared to the HSMS-280F-TR2G's 70V rating. Use this substitute only in applications where the circuit operates below 15V reverse bias. Additionally, its maximum junction temperature is 125°C versus 150°C for the original part.

Q: What is the difference between BAS70-05W,115 and BAS70-05W,135?

A: Both parts are electrically identical. The difference is in packaging configuration: ,115 and ,135 designate different reel formats for tape and reel delivery. Select based on your procurement and assembly equipment requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original HSMS-280F-TR2G RoHS status was not specified in available documentation.

Q: Do the substitute parts maintain the same package footprint?

A: Yes. All substitute parts use SC-70 or SOT-323 surface mount packaging, maintaining identical PCB footprint compatibility with the HSMS-280F-TR2G.

Q: What is the current handling difference between the original and substitutes?

A: The HSMS-280F-TR2G is rated for 1A maximum current. The BAS70-05W variants are rated for 70mA per diode. The 1PS70SB85,115 is rated for 30mA per diode. Verify your application's current requirements before selection.
