Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54SW-7-G is determined by electrical and mechanical parameter equivalence across the following critical specifications:

Electrical Parameters:

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

Mechanical Parameters:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Compliance Parameters:

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

All substitute parts listed maintain identical electrical performance characteristics and physical packaging specifications. Substitutes are grouped as direct manufacturer equivalents (same manufacturer, different packaging or qualification) and parametric equivalents (alternative manufacturers with identical electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalent - Diodes Incorporated:

BAT54SW-7-F is the primary active substitute for the obsolete BAT54SW-7-G. Both parts are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications. The BAT54SW-7-F differs only in packaging format (Tape & Reel) and product status (Active). This part is suitable for direct replacement in new production and redesign efforts.

Parametric Equivalent - Diodes Incorporated (Automotive Grade):

BAT54SWQ-7-F is a parametric equivalent manufactured by Diodes Incorporated with active product status. This part maintains AEC-Q101 automotive qualification matching the original BAT54SW-7-G specification. The BAT54SWQ-7-F is appropriate for applications requiring automotive-grade certification and qualification traceability.

Parametric Equivalent - Taiwan Semiconductor Corporation:

BAT54SW RVG is a parametric equivalent manufactured by Taiwan Semiconductor Corporation with active product status. All electrical and mechanical parameters are identical to the BAT54SW-7-G. Operating temperature specification differs (125°C maximum versus -65°C to 125°C range). This part is suitable for applications where the reduced temperature range is acceptable.

Parametric Equivalent - Micro Commercial Co:

BAT54SWT-TP is a parametric equivalent manufactured by Micro Commercial Co with active product status and Tape & Reel packaging. All electrical and mechanical parameters are identical to the BAT54SW-7-G. Operating temperature specification differs (-55°C to 125°C versus -65°C to 125°C range). This part is suitable for applications where the reduced low-temperature specification is acceptable.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can BAT54SW-7-F be used as a direct replacement for BAT54SW-7-G?

A: Yes. BAT54SW-7-F is manufactured by Diodes Incorporated and maintains identical electrical specifications (30 V reverse voltage, 200 mA current rating, 1 V forward voltage, 5 ns reverse recovery time) and mechanical packaging (SC-70, SOT-323 surface mount). The primary difference is product status (Active versus Obsolete) and packaging format (Tape & Reel). Electrical and functional performance are equivalent.

Q: What is the difference between BAT54SWQ-7-F and BAT54SW-7-F?

A: Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications. BAT54SWQ-7-F carries AEC-Q101 automotive qualification, while BAT54SW-7-F does not specify automotive qualification. Selection depends on whether automotive-grade certification is required for the application.

Q: Are the Taiwan Semiconductor Corporation and Micro Commercial Co alternatives suitable for automotive applications?

A: BAT54SW RVG (Taiwan Semiconductor Corporation) and BAT54SWT-TP (Micro Commercial Co) do not specify AEC-Q101 automotive qualification. These parts are suitable for non-automotive applications. For automotive applications requiring AEC-Q101 certification, BAT54SWQ-7-F is the appropriate selection.

Q: What is the significance of the operating temperature range differences?

A: The BAT54SW-7-G specifies -65°C to 125°C junction temperature range. BAT54SW RVG specifies 125°C maximum (no minimum specified), and BAT54SWT-TP specifies -55°C to 125°C. Applications requiring operation below -55°C must use BAT54SW-7-G, BAT54SWQ-7-F, or BAT54SW-7-F. Applications with minimum operating temperature above -55°C can use any substitute.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use SC-70, SOT-323 surface mount packaging. Packaging format (Tape & Reel versus other formats) varies by supplier. BAT54SW-7-F and BAT54SWT-TP are specified as Tape & Reel. Verify packaging format requirements with your procurement specification before final part selection.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All substitute parts listed (BAT54SW-7-F, BAT54SWQ-7-F, BAT54SW RVG, and BAT54SWT-TP) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are suitable for standard manufacturing processes without additional handling requirements.

Q: Which substitute part should be selected for new design work?

A: For new designs without automotive qualification requirements, BAT54SW-7-F is the recommended selection due to active product status, established supply chain availability, and identical electrical specifications. For automotive applications, BAT54SWQ-7-F is the appropriate selection due to AEC-Q101 qualification. Both parts are manufactured by Diodes Incorporated, the original manufacturer of the BAT54SW-7-G.
