HSMS-270C-TR1 Equivalent & Substitute Parts

Part Overview

The HSMS-270C-TR1 is a Schottky diode array in a 1 Pair Series Connection configuration, rated for 15V peak reverse voltage and 750 mA maximum current with 825 mW power dissipation. Manufactured by Broadcom Limited, this component is packaged in SC-70/SOT-323 surface mount format. The part is currently listed as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HSMS-270C-TR1 is determined by the following critical parameters:

• Diode configuration: 1 Pair Series Connection Schottky technology
• Package compatibility: SC-70/SOT-323 surface mount form factor
• Voltage rating: Minimum 15V peak reverse voltage capability
• Current handling: Sufficient current capacity for application requirements
• Thermal performance: Operating temperature range compatibility

Two active substitute parts meet these criteria with different performance characteristics:

1PS70SB84,115 (Nexperia USA Inc.) maintains the exact 15V voltage rating with reduced current capacity (30 mA per diode) and active product status with AEC-Q100 automotive qualification.

BAT54SWFILM (STMicroelectronics) provides enhanced voltage rating (40V) and higher current capacity (300 mA per diode) with extended temperature range (-40°C to 150°C) and active product status.

Parameter Comparison

Engineering Selection Recommendations

1PS70SB84,115 is suitable for applications requiring exact voltage matching (15V) with lower current demands. This part offers active product status, ROHS3 compliance, and AEC-Q100 automotive qualification, making it appropriate for automotive and regulated applications where compliance certifications are mandatory.

BAT54SWFILM is suitable for applications where higher voltage margin (40V) and increased current capacity (300 mA) provide design flexibility. This part offers active product status, ROHS3 compliance, and extended operating temperature range (-40°C to 150°C), making it appropriate for applications requiring broader thermal performance.

Both substitute parts are available in the identical SC-70/SOT-323 package, enabling direct physical replacement. Selection between substitutes depends on specific application current requirements and voltage margin needs.

Frequently Asked Questions (FAQ)

Q: Can 1PS70SB84,115 directly replace HSMS-270C-TR1 in all applications?

A: Direct replacement is possible only in applications where current requirements do not exceed 30 mA per diode. The 1PS70SB84,115 maintains the 15V voltage rating but has significantly reduced current capacity compared to the original 750 mA specification.

Q: Can BAT54SWFILM directly replace HSMS-270C-TR1 in all applications?

A: Direct replacement is possible in applications where the 40V voltage rating is acceptable. The BAT54SWFILM provides higher current capacity (300 mA) than 1PS70SB84,115 but still below the original 750 mA specification. The extended temperature range (-40°C to 150°C) is compatible with the original 150°C maximum junction temperature.

Q: Are both substitute parts available in the same package?

A: Yes. Both 1PS70SB84,115 and BAT54SWFILM are packaged in SC-70/SOT-323 surface mount format, identical to the original HSMS-270C-TR1, enabling direct physical replacement on PCBs.

Q: What is the primary difference between the two substitute options?

A: The primary differences are voltage rating (1PS70SB84,115 at 15V versus BAT54SWFILM at 40V) and current capacity (1PS70SB84,115 at 30 mA versus BAT54SWFILM at 300 mA). Selection depends on application-specific voltage and current requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 1PS70SB84,115 and BAT54SWFILM are ROHS3 compliant, whereas the original HSMS-270C-TR1 is RoHS non-compliant. This compliance improvement may be required for new designs and applications subject to RoHS regulations.

Q: Does 1PS70SB84,115 have automotive qualification?

A: Yes. The 1PS70SB84,115 carries AEC-Q100 automotive qualification, making it suitable for automotive applications. The BAT54SWFILM qualification status is not specified in the provided data.
