BAS40W-06-7 Equivalent & Substitute Parts

Part Overview

The BAS40W-06-7 is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Anode design rated for 40 V DC reverse voltage with 200 mA average rectified current per diode. The component is housed in an SC-70, SOT-323 surface mount package and is supplied in Cut Tape (CT) & Digi-Reel® packaging. This part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the original part number becomes unavailable, when alternative packaging formats are required, or when design specifications permit operation within the electrical and mechanical tolerances of functionally similar components from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS40W-06-7 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Anode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 200 mA
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit operating margins
• Operating Temperature - Junction: Equal to or greater than specified minimum
• Reverse Recovery Time (trr): Not a limiting factor for substitution
• Current - Reverse Leakage @ Vr: Not a limiting factor for substitution

Substitute parts must maintain identical mechanical compatibility and electrical ratings at or above the original specification to ensure direct replacement capability without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred Substitutes):

BAS40W-06-7-F (Diodes Incorporated) and BAT854AW,115 (Nexperia USA Inc.) are direct electrical and mechanical equivalents to the BAS40W-06-7. Both maintain identical 40 V reverse voltage rating, 200 mA average rectified current per diode, SC-70 SOT-323 package configuration, and ROHS3 compliance. The primary distinction is packaging format: BAS40W-06-7-F is supplied in Tape & Reel (TR) format, while the original part is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts maintain Active product status and unlimited moisture sensitivity rating.

Functional Equivalents (Current-Reduced Substitutes):

BAS40-06W,115 (Nexperia USA Inc.) and BAS4006WH6327XTSA1 (Infineon Technologies) are functionally equivalent with reduced current ratings of 120 mA per diode. These parts maintain the 40 V reverse voltage specification, identical package configuration, and full compliance certifications. Selection of these parts is appropriate when circuit design permits operation at reduced current levels or when thermal management benefits from lower current handling.

Enhanced Current Capability Substitute:

BAT6406WH6327XTSA1 (Infineon Technologies) provides enhanced current capability at 250 mA per diode while maintaining the 40 V reverse voltage and SC-70 SOT-323 package. This part includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring higher current capacity within the same voltage and package constraints. All compliance certifications remain equivalent to the original part.

All substitute parts maintain Active product status, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can BAS40W-06-7-F be used as a direct replacement for BAS40W-06-7?

A: Yes. BAS40W-06-7-F is a direct electrical and mechanical equivalent. Both parts share identical 40 V reverse voltage rating, 200 mA average rectified current per diode, SC-70 SOT-323 package, and ROHS3 compliance. The difference is packaging format: BAS40W-06-7-F is supplied in Tape & Reel (TR) format instead of Cut Tape (CT) & Digi-Reel®. PCB assembly compatibility is identical.

Q: What is the difference between BAS40W-06-7 and BAT854AW,115?

A: Both parts are electrically and mechanically equivalent with 40 V reverse voltage, 200 mA average rectified current per diode, and SC-70 SOT-323 package configuration. The primary difference is manufacturer: BAS40W-06-7 is manufactured by Diodes Incorporated, while BAT854AW,115 is manufactured by Nexperia USA Inc. Both maintain identical compliance certifications and product status.

Q: Can I use BAS40-06W,115 or BAS4006WH6327XTSA1 if the circuit only requires 120 mA per diode?

A: Yes. Both BAS40-06W,115 and BAS4006WH6327XTSA1 are rated for 120 mA average rectified current per diode, which is sufficient for applications requiring 120 mA or less. Both maintain the 40 V reverse voltage specification and SC-70 SOT-323 package. These parts are suitable substitutes when circuit design permits operation at the reduced current level.

Q: Is BAT6406WH6327XTSA1 compatible with the original BAS40W-06-7 application?

A: BAT6406WH6327XTSA1 is mechanically and electrically compatible with identical 40 V reverse voltage and SC-70 SOT-323 package. The part provides enhanced current capability at 250 mA per diode. This part includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring higher current capacity. All compliance certifications match the original part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original BAS40W-06-7 specification. All parts are suitable for current manufacturing processes and environmental standards.

Q: What packaging formats are available for these substitute parts?

A: BAS40W-06-7 is supplied in Cut Tape (CT) & Digi-Reel® format. All substitute parts listed are supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard PCB assembly equipment. Selection between packaging formats depends on production volume and assembly line requirements.

Q: Can I substitute parts with different forward voltage specifications?

A: Forward voltage differences are allowable within circuit design margins. BAS40W-06-7-F and BAT854AW,115 specify forward voltage at different test conditions (1 V @ 40 mA versus 550 mV @ 100 mA), but both are suitable substitutes. Circuit design must accommodate the specified forward voltage characteristics of the selected part. Consult detailed datasheets for precise forward voltage performance at your specific operating current.
