Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54AQ-13 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 1 Pair Common Anode
• Technology: Schottky
• Maximum reverse voltage: 30 V
• Average rectified current per diode: 200 mA
• Forward voltage: 800 mV @ 100 mA
• Reverse recovery time: 5 ns
• Reverse leakage current: 2 µA @ 25 V

Mechanical Equivalence Criteria:

• Package type: SOT-23-3 (TO-236-3, SC-59)
• Mounting type: Surface Mount

Compliance Criteria:

• Automotive grade qualification
• AEC-Q101 certification
• ROHS3 compliance
• REACH unaffected status

All substitute parts listed maintain full parametric equivalence across these criteria, enabling direct replacement in circuit designs without modification to PCB layout, schematic topology, or thermal management considerations.

Parameter Comparison

Engineering Selection Recommendations

BAT54AQ-7-F (Diodes Incorporated)

This substitute maintains complete parametric equivalence with the BAT54AQ-13 across all electrical and mechanical specifications. Both parts share identical manufacturer lineage, AEC-Q101 qualification, and operating temperature range of -65°C to 150°C. The BAT54AQ-7-F is available in higher inventory quantity (6300 pieces) and carries MSL 1 rating. Selection of this part introduces no design or reliability trade-offs.

BAT54AHE3-TP (Micro Commercial Co)

This substitute provides parametric equivalence in all critical electrical characteristics and package specifications. The operating temperature range is constrained to -55°C to 125°C, which is narrower than the BAT54AQ-13. This part maintains AEC-Q101 qualification and ROHS3 compliance. Selection of this part is appropriate for applications where the reduced temperature range does not conflict with system requirements.

CBAT54A TR PBFREE (Central Semiconductor Corp)

This substitute maintains full parametric equivalence across all electrical specifications and package requirements. The operating temperature range matches the BAT54AQ-13 at -65°C to 150°C. AEC-Q101 qualification status is not specified in the provided data. This part carries ROHS3 compliance and MSL 1 rating. Selection of this part is appropriate where manufacturer diversification is required and qualification status is verified through independent documentation.

Frequently Asked Questions (FAQ)

Q: Can BAT54AQ-7-F be used as a direct replacement for BAT54AQ-13?

A: Yes. Both parts are manufactured by Diodes Incorporated and maintain identical electrical parameters, package specifications, operating temperature range, and automotive qualifications. Direct substitution requires no circuit modifications or PCB layout changes.

Q: What is the difference between BAT54AHE3-TP and BAT54AQ-13?

A: The primary difference is the operating temperature range. BAT54AHE3-TP operates from -55°C to 125°C, while BAT54AQ-13 operates from -65°C to 150°C. All other electrical and mechanical parameters are identical. Selection depends on whether the application requires the extended temperature range.

Q: Are all substitute parts automotive qualified?

A: BAT54AQ-7-F and BAT54AHE3-TP carry explicit AEC-Q101 qualification. CBAT54A TR PBFREE is specified as automotive grade, but AEC-Q101 qualification status is not provided in the available data. Verification of qualification status through manufacturer documentation is required for applications with strict automotive certification requirements.

Q: Do all substitute parts have the same package footprint?

A: Yes. All parts use the SOT-23-3 package (also designated TO-236-3 or SC-59). PCB footprints are identical, and no layout modifications are required for substitution.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. Parts with MSL 1 do not require desiccant storage or baking procedures prior to reflow soldering.

Q: Can CBAT54A TR PBFREE be substituted if AEC-Q101 qualification is required?

A: AEC-Q101 qualification status for CBAT54A TR PBFREE is not specified in the provided technical data. Confirmation of qualification status through Central Semiconductor Corp documentation is necessary before selection for applications with mandatory automotive certification requirements.

Q: Are there inventory considerations for part selection?

A: BAT54AQ-7-F has the highest available inventory at 6300 pieces, followed by CBAT54A TR PBFREE at 4827 pieces and BAT54AHE3-TP at 3782 pieces. BAT54AQ-13 has 791 pieces available. Inventory levels may influence supply chain decisions but do not affect electrical or mechanical compatibility.
