BAS40DW-05-7 Equivalent & Substitute Parts

Part Overview

The BAS40DW-05-7 is a Schottky diode array featuring 2 pair common cathode configuration rated for 40 V DC reverse voltage and 200 mA average rectified current per diode. Manufactured by Diodes Incorporated in a 6-TSSOP (SOT-363) surface mount package, this component is designed for small signal rectification applications requiring fast switching characteristics with 5 ns reverse recovery time.

The BAS40DW-05-7 is currently discontinued at DiGi Electronics. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility within the specified parameter ranges while accommodating packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40DW-05-7 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Diode configuration must be 2 Pair Common Cathode
• Technology must be Schottky
• DC reverse voltage rating must be 40 V or greater
• Average rectified current per diode must be 200 mA or greater
• Forward voltage drop must not exceed 1 V @ 40 mA
• Reverse recovery time must be 5 ns or less
• Operating temperature range must encompass -55°C to 125°C

Mechanical Compatibility Criteria:

• Package must be 6-TSSOP, SC-88, or SOT-363
• Mounting type must be Surface Mount
• Moisture sensitivity level must be 1 (Unlimited)

Compliance Considerations:

• RoHS compliance status affects suitability for regulated applications
• Packaging format (Cut Tape, Tape & Reel, or Digi-Reel) affects procurement and assembly processes

Substitute parts are grouped into two categories: direct electrical equivalents with identical or superior current ratings, and functional alternatives with reduced current ratings that maintain voltage and switching characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (200 mA Rating):

BAS40DW-05-7-F and BAS40DW-05-TP are direct electrical equivalents to the BAS40DW-05-7, maintaining identical current ratings of 200 mA per diode and all critical electrical parameters. Both parts are currently in active product status.

BAS40DW-05-7-F (Diodes Incorporated) is available in Cut Tape and Digi-Reel packaging formats and carries ROHS3 compliance certification. This part is the preferred direct replacement when RoHS compliance is required for new designs or regulated applications.

BAS40DW-05-TP (Micro Commercial Co) is supplied in Tape & Reel format and also carries ROHS3 compliance. This part is suitable for high-volume production environments where Tape & Reel packaging is standard.

Functional Alternatives (120 mA Rating):

1PS88SB48,115 (Nexperia USA Inc.) and BAS40-05V,115 (Nexperia USA Inc.) are functional alternatives with reduced current ratings of 120 mA per diode. These parts maintain the 40 V reverse voltage rating and 1 V forward voltage specification. Both carry ROHS3 compliance and MSL 1 rating.

1PS88SB48,115 is supplied in Tape & Reel format and maintains the 6-TSSOP package. This part includes AEC-Q100 automotive qualification and is suitable for applications where automotive-grade components are specified.

BAS40-05V,115 is supplied in Tape & Reel format but uses SOT-563 or SOT-666 package variants, which differ from the original SOT-363 package. This part carries a "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where package compatibility is not a constraint.

Compliance Considerations:

The original BAS40DW-05-7 is RoHS non-compliant. All substitute parts listed carry ROHS3 compliance, making them suitable for applications subject to RoHS regulations. Selection of a compliant substitute part is necessary for new designs targeting regulated markets.

Frequently Asked Questions (FAQ)

Q: Can BAS40DW-05-7-F be used as a direct replacement for BAS40DW-05-7?

A: Yes. BAS40DW-05-7-F is a direct electrical equivalent with identical diode configuration, voltage rating, current rating, forward voltage, and reverse recovery time. Both parts are housed in the 6-TSSOP (SOT-363) package. The primary difference is that BAS40DW-05-7-F carries ROHS3 compliance, whereas the original part is RoHS non-compliant. Packaging format differs (Cut Tape & Digi-Reel versus Cut Tape), which may affect procurement and assembly processes.

Q: What is the difference between BAS40DW-05-TP and BAS40DW-05-7-F?

A: Both parts are electrical equivalents with 200 mA current ratings and identical electrical specifications. The primary differences are manufacturer (Micro Commercial Co versus Diodes Incorporated) and packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Both carry ROHS3 compliance and are in active product status. Selection between these parts depends on packaging requirements and supplier availability.

Q: Can 1PS88SB48,115 replace BAS40DW-05-7 in all applications?

A: 1PS88SB48,115 is a functional alternative with a reduced current rating of 120 mA per diode, compared to 200 mA for the original part. This part maintains the 40 V reverse voltage rating and 1 V forward voltage specification. Substitution is permissible only in applications where the circuit current does not exceed 120 mA per diode. 1PS88SB48,115 includes AEC-Q100 automotive qualification and is suitable for automotive applications. The 6-TSSOP package is compatible with the original footprint.

Q: Why is BAS40-05V,115 marked "Not For New Designs"?

A: BAS40-05V,115 carries a "Not For New Designs" status, indicating that the manufacturer recommends against using this part in new product development. This part uses SOT-563 or SOT-666 package variants, which differ from the original SOT-363 package and require different PCB footprints. This part should be used only for legacy system maintenance or repair applications where package compatibility is not a constraint and existing inventory must be utilized.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by the following parameters: diode configuration (2 Pair Common Cathode), technology (Schottky), DC reverse voltage rating (40 V or greater), average rectified current per diode (200 mA or greater for direct equivalents), forward voltage drop (1 V @ 40 mA maximum), reverse recovery time (5 ns or less), operating temperature range (-55°C to 125°C minimum), package type (6-TSSOP, SC-88, or SOT-363), and mounting type (Surface Mount). Reduced current ratings (120 mA) are permissible only when circuit design allows lower current operation.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel) does not affect electrical performance. Format selection is determined by procurement and assembly process requirements. Cut Tape format is suitable for manual assembly or small-volume production. Tape & Reel format is standard for automated assembly and high-volume production environments. Digi-Reel format combines benefits of both formats for flexible manufacturing processes.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed carry ROHS3 compliance. The original BAS40DW-05-7 is RoHS non-compliant. Selection of a compliant substitute part is necessary for applications subject to RoHS regulations or for new designs targeting regulated markets.

Q: What is the significance of the 200 nA reverse leakage current specification?

A: The BAS40DW-05-7, BAS40DW-05-7-F, and BAS40DW-05-TP specify 200 nA reverse leakage current at 30 V. The alternative parts 1PS88SB48,115 and BAS40-05V,115 specify 10 µA reverse leakage current at 40 V, which is significantly higher. In applications sensitive to reverse leakage current, the original specification or direct equivalents are required. In general-purpose rectification applications, the higher leakage current of alternative parts is typically acceptable.

Q: Can these parts be used interchangeably in existing PCB designs?

A: BAS40DW-05-7-F and BAS40DW-05-TP can be used interchangeably with the original BAS40DW-05-7 in existing PCB designs, as all three parts use the 6-TSSOP (SOT-363) package with identical pinout and footprint. 1PS88SB48,115 also uses the 6-TSSOP package and is footprint-compatible. BAS40-05V,115 uses SOT-563 or SOT-666 packages and requires a different PCB footprint; this part is not interchangeable without PCB redesign.
