BAT54AWF Equivalent & Substitute Parts

Part Overview

The BAT54AWF is a Schottky diode array manufactured by Nexperia USA Inc., configured as 1 pair common anode with a maximum reverse voltage of 30 V and average rectified current of 200 mA per diode. The device is packaged in SC-70, SOT-323 surface mount format and is qualified to AEC-Q101 automotive standards. This part is currently active in production with 6440 units in stock.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, manufacturing discontinuation, or procurement preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT54AWF are classified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Diode Configuration: 1 Pair Common Anode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V

Parametric Equivalents maintain all critical electrical parameters and forward voltage specifications. These parts are direct functional replacements.

Similar Parts maintain all critical electrical parameters but may have variations in forward voltage (Vf) or operating temperature range. These parts are functionally compatible with circuit-level verification.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacements):

BAT54AW,115, BAT5406WH6327XTSA1, BAT54AWT1G, and SBAT54AWT1G are parametric equivalents to the BAT54AWF. These parts maintain identical electrical specifications including forward voltage, reverse voltage, current ratings, and reverse recovery time. All substitute parts are active products with ROHS3 compliance and AEC-Q101 qualification (where specified by manufacturer). These parts are suitable for direct substitution in applications where the BAT54AWF is specified.

Similar Part (Circuit-Level Verification Required):

BAT54AW-7-F manufactured by Diodes Incorporated maintains all critical electrical parameters with the exception of forward voltage specification (1 V @ 100 mA versus 800 mV @ 100 mA). This part is suitable for substitution in applications where forward voltage variation within this range is acceptable. Circuit-level analysis is required to confirm compatibility with voltage regulation and signal integrity requirements.

Packaging Considerations:

BAT54AW,115 is supplied in Cut Tape (CT) & Digi-Reel® packaging, differing from the standard Tape & Reel (TR) format of the main part. All other substitutes are supplied in Tape & Reel (TR) format, matching the BAT54AWF packaging specification.

Frequently Asked Questions (FAQ)

Q: Can BAT54AW,115 be used as a direct replacement for BAT54AWF?

A: Yes. BAT54AW,115 is a parametric equivalent manufactured by the same supplier (Nexperia USA Inc.) with identical electrical specifications. The only difference is packaging format: BAT54AW,115 is supplied in Cut Tape (CT) & Digi-Reel® while BAT54AWF is supplied in Tape & Reel (TR). Both formats are compatible with standard surface mount assembly processes.

Q: What is the difference between BAT54AWT1G and SBAT54AWT1G?

A: Both parts are manufactured by onsemi and maintain identical electrical specifications. The primary difference is the base product designation: BAT54AWT1G uses the BAT54 base product number, while SBAT54AWT1G uses the SBAT54 base product number. Both are parametric equivalents to BAT54AWF with identical performance characteristics.

Q: Why does BAT54AW-7-F have a different forward voltage specification?

A: BAT54AW-7-F is manufactured by Diodes Incorporated and specifies a maximum forward voltage of 1 V @ 100 mA, compared to 800 mV @ 100 mA for the BAT54AWF. This represents a manufacturing tolerance variation between suppliers. The part remains functionally compatible for most applications, but circuit designs with tight voltage regulation requirements must verify compatibility.

Q: Are all substitute parts AEC-Q101 qualified?

A: The BAT54AWF, BAT54AW,115, BAT5406WH6327XTSA1, BAT54AWT1G, and SBAT54AWT1G are all AEC-Q101 qualified for automotive applications. BAT54AW-7-F qualification status is not specified in the provided data.

Q: Can these parts be used interchangeably in automotive applications?

A: All parametric equivalents (BAT54AW,115, BAT5406WH6327XTSA1, BAT54AWT1G, SBAT54AWT1G) maintain AEC-Q101 qualification and are suitable for automotive applications. BAT54AW-7-F requires verification of automotive qualification status before use in automotive designs.

Q: What is the difference between SC-70 and SOT-323 package designations?

A: SC-70 and SOT-323 refer to the same physical package format. SC-70 is the JEDEC designation, while SOT-323 is the industry standard designation. These terms are used interchangeably for this device.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (BAT54AW,115, BAT5406WH6327XTSA1, BAT54AWT1G, BAT54AW-7-F, SBAT54AWT1G) are ROHS3 compliant.
