HSMS-280E-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-280E-TR2G is an RF Schottky diode manufactured by Broadcom Limited, configured as a 1 Pair Common Anode diode array 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-280E-TR2G is determined by the following critical parameters:

Configuration Match: All substitute parts must maintain 1 Pair Common Anode diode array configuration to ensure pin compatibility and functional equivalence.

Package Match: All substitutes must use SC-70 or SOT-323 surface mount packaging for direct PCB placement compatibility.

Voltage Rating: Substitute parts must meet or exceed the 70V peak reverse voltage specification to maintain circuit protection and reliability margins.

Current Capability: Substitute parts must support the application's current requirements within the specified operating range.

Temperature Range: Operating junction temperature must support the 150°C maximum requirement or higher.

The three qualified substitutes meet these criteria while offering active product status and improved availability compared to the obsolete HSMS-280E-TR2G.

Parameter Comparison

Engineering Selection Recommendations

BAS70-06W,115 (Primary Substitute): This Nexperia part provides exact voltage rating match at 70V and maintains the 150°C maximum junction temperature specification. Current rating of 70mA is suitable for low-signal RF applications. Active product status ensures long-term availability. ROHS3 compliance and AEC-Q100 automotive qualification provide regulatory alignment.

BAW56WT-TP (Secondary Substitute): This Micro Commercial Co part exceeds voltage requirements at 75V and supports higher current at 150mA. Operating temperature range extends to -55°C, providing broader thermal flexibility. Standard diode technology differs from Schottky, requiring circuit validation for forward voltage characteristics. Active status and ROHS3 compliance support procurement continuity.

1PS70SB86,115 (Limited Substitution): This Nexperia part maintains Schottky technology and common anode configuration but is limited to 15V reverse voltage. Suitable only for applications where the 70V rating is not a functional requirement. Current rating of 30mA is the lowest among substitutes. Active status and automotive qualification are available.

Frequently Asked Questions (FAQ)

Q: Can I use 1PS70SB86,115 as a direct replacement for HSMS-280E-TR2G?

A: No. The 1PS70SB86,115 is rated for only 15V reverse voltage compared to the HSMS-280E-TR2G's 70V specification. Use this part only if your circuit operates at voltages below 15V and does not require the higher voltage protection of the original design.

Q: What is the difference between BAS70-06W,115 and BAW56WT-TP?

A: BAS70-06W,115 uses Schottky technology with 70V rating and 70mA current. BAW56WT-TP uses standard diode technology with 75V rating and 150mA current. The Schottky variant offers lower forward voltage drop, while the standard diode provides higher current capacity. Technology selection depends on circuit requirements for forward voltage characteristics and current handling.

Q: Are all substitutes pin-compatible with the HSMS-280E-TR2G?

A: Yes. All three substitutes use SC-70 or SOT-323 packaging with 1 Pair Common Anode configuration, ensuring identical pinout and PCB footprint compatibility.

Q: Do the substitute parts meet compliance requirements?

A: All three active substitutes are ROHS3 compliant. BAS70-06W,115 and BAW56WT-TP carry AEC-Q100 automotive qualification. Verify specific compliance requirements for your application.

Q: What is the operating temperature limitation for each substitute?

A: HSMS-280E-TR2G and BAS70-06W,115 both support 150°C maximum junction temperature. BAW56WT-TP supports -55°C to 150°C. 1PS70SB86,115 is limited to 125°C maximum, which may restrict use in high-temperature applications.
