BAT54SWF Equivalent & Substitute Parts

Part Overview

The BAT54SWF is an active Schottky diode array manufactured by Nexperia USA Inc., configured as a 1 pair series connection rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. The device is housed in a surface mount SC-70, SOT-323 package and is qualified to AEC-Q101 automotive standards. This component is suitable for applications requiring small signal rectification, reverse polarity protection, and high-speed switching in automotive and industrial environments. Substitute parts are identified based on matching electrical specifications, package compatibility, and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT54SWF are qualified based on the following critical parameters:

Electrical Specifications Match:

• Diode configuration: 1 pair series connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V

Package Compatibility:

• Mounting Type: Surface Mount
• Package / Case: SC-70, SOT-323

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts meet these criteria. Operating temperature ranges vary among manufacturers but do not affect functional substitution within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and environmental regulatory adherence.

Nexperia Substitutes (BAT54SW,115): Direct parametric equivalent from the same manufacturer as the BAT54SWF. Identical electrical specifications and package designation. Suitable for direct replacement in applications where manufacturer consistency is required.

onsemi Substitutes (BAT54SWT1G, NSVBAT54SWT1G): Both onsemi variants meet all electrical and package requirements. BAT54SWT1G is supplied in Cut Tape & Digi-Reel packaging, while NSVBAT54SWT1G is supplied in Tape & Reel format. The BAT54SWT1G specifies a maximum junction temperature of 125°C, which is lower than the BAT54SWF specification of 150°C. Selection between these variants depends on packaging requirements and thermal operating conditions.

Infineon Substitute (BAT5404WH6327XTSA1): Meets all critical electrical specifications and package requirements. Supplied in Tape & Reel format. Suitable for applications where multi-source qualification is required.

Selection among substitutes should be based on packaging format availability, supply chain requirements, and thermal operating envelope of the target application.

Frequently Asked Questions (FAQ)

Q: Can BAT54SW,115 be used as a direct replacement for BAT54SWF?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, package designation (SC-70, SOT-323), and compliance certifications. They are parametric equivalents.

Q: What is the difference between BAT54SWT1G and NSVBAT54SWT1G?

A: Both are onsemi Schottky diode arrays with identical electrical specifications. The primary difference is packaging format: BAT54SWT1G is supplied in Cut Tape & Digi-Reel, while NSVBAT54SWT1G is supplied in Tape & Reel. Additionally, BAT54SWT1G specifies a maximum junction temperature of 125°C, whereas NSVBAT54SWT1G specifies 150°C.

Q: Are all substitute parts qualified to the same automotive standard?

A: The BAT54SWF is qualified to AEC-Q101. The Nexperia substitute (BAT54SW,115) and Infineon substitute (BAT5404WH6327XTSA1) share this qualification. The onsemi variants (BAT54SWT1G and NSVBAT54SWT1G) do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 certification, Nexperia or Infineon substitutes are appropriate.

Q: Can these parts be used interchangeably in high-temperature applications?

A: All parts are rated for 150°C maximum junction temperature except BAT54SWT1G, which is rated to 125°C. For applications operating near or above 125°C, BAT54SWF, BAT54SW,115, NSVBAT54SWT1G, or BAT5404WH6327XTSA1 are suitable. BAT54SWT1G is not recommended for such applications.

Q: What packaging formats are available?

A: BAT54SWF and BAT54SW,115 are available in Cut Tape (CT) & Digi-Reel format. BAT54SWT1G is available in Cut Tape (CT) & Digi-Reel format. NSVBAT54SWT1G and BAT5404WH6327XTSA1 are available in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What is the base product number for each substitute?

A: BAT54SW,115 and BAT54SWT1G share the base product number BAT54. NSVBAT54SWT1G uses base product number NSVBAT54. BAT5404WH6327XTSA1 uses base product number BAT5404. Base product numbers indicate the core device family but do not affect functional substitution.
