HSMS-270C-TR2G Equivalent & Substitute Parts

Part Overview

The HSMS-270C-TR2G is a Schottky diode array manufactured by Broadcom Limited, configured as a 1 pair series connection with a peak reverse voltage rating of 15V and maximum power dissipation of 825 mW in SOT-323 packaging. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Substitute parts must maintain compatibility across electrical performance parameters, mechanical packaging, and thermal characteristics to ensure reliable circuit operation.

2. BAT54SWFILM (STMicroelectronics) - Active product status, enhanced voltage and current ratings

Parameter Comparison

Engineering Selection Recommendations

1PS70SB84,115 (Nexperia USA Inc.): This substitute maintains identical voltage and configuration specifications to the HSMS-270C-TR2G. The part carries active product status with automotive-grade qualification and AEC-Q100 certification, ensuring long-term availability and supply chain stability. Current rating of 30 mA per diode is suitable for applications within this specification window. Operating temperature maximum of 125°C is lower than the original part; applications requiring sustained operation above 125°C junction temperature require thermal analysis.

BAT54SWFILM (STMicroelectronics): This substitute provides enhanced electrical performance with 40V reverse voltage rating and 300 mA current capability, offering design margin above the original 15V, 750 mA specification. Active product status and ROHS3 compliance support procurement continuity. Operating temperature range matches the original part at 150°C maximum. This option is suitable for applications where higher voltage or current headroom is beneficial or where the original current specification of 750 mA exceeds circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1PS70SB84,115 replace the HSMS-270C-TR2G in all applications?

A: The 1PS70SB84,115 maintains matching voltage and configuration specifications. Substitution is valid for applications where diode current does not exceed 30 mA per element. Applications requiring the full 750 mA capability of the original part require the BAT54SWFILM or equivalent higher-current alternative.

Q: What is the impact of the 125°C maximum junction temperature on the 1PS70SB84,115?

A: The 1PS70SB84,115 specifies a maximum operating temperature of 125°C, compared to 150°C for the HSMS-270C-TR2G. Applications with sustained junction temperatures between 125°C and 150°C require thermal design review or selection of BAT54SWFILM, which maintains the 150°C rating.

Q: Are both substitute parts pin-compatible with the HSMS-270C-TR2G?

A: Both substitutes use identical SC-70, SOT-323 packaging. Physical pin compatibility is maintained. Electrical functionality as a 1 pair series Schottky diode configuration is preserved in both alternatives.

Q: What compliance certifications apply to the substitute parts?

A: The 1PS70SB84,115 carries AEC-Q100 automotive qualification and ROHS3 compliance. The BAT54SWFILM carries ROHS3 compliance. Both parts are REACH unaffected and classified as EAR99 for export control purposes, matching the original part classification.

Q: Which substitute should be selected for new designs?

A: Selection depends on circuit current requirements. For applications requiring 30 mA or less per diode, the 1PS70SB84,115 provides automotive-qualified continuity. For applications requiring higher current capability or operating margin, the BAT54SWFILM provides enhanced performance within the same package footprint.
