BAS40TW-7 Equivalent & Substitute Parts

Part Overview

The BAS40TW-7 is a Schottky diode array containing three independent 40 V, 200 mA (DC) rectifier elements in a 6-TSSOP (SOT-363) surface mount package. This component is manufactured by Diodes Incorporated and is classified as discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives for ongoing design and procurement requirements.

The BAS40TW-7 serves applications requiring low forward voltage drop, fast switching characteristics, and compact surface mount integration. Equivalent and substitute parts must maintain identical electrical performance parameters and package compatibility to ensure direct board-level replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS40TW-7 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 3 Independent
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Reverse Recovery Time (trr): 5 ns
• Operating Temperature - Junction: -55°C ~ 125°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 6-TSSOP, SC-88, SOT-363
• Supplier Device Package: SOT-363

Compliance Parameters (Must Match):

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

Substitute parts are classified as either parametric equivalents (identical electrical and mechanical specifications from alternative manufacturers) or direct manufacturer equivalents (same part number from different suppliers). All identified substitutes maintain full compatibility with the original BAS40TW-7 design requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BAS40TW-7-F

The BAS40TW-7-F is a parametric equivalent manufactured by Diodes Incorporated with active product status. This part maintains identical electrical specifications and package configuration to the BAS40TW-7. The primary distinction is packaging format (Tape & Reel versus bulk), which does not affect electrical performance or board-level compatibility. This option provides continuity with the original manufacturer and is suitable for direct substitution in all applications.

Secondary Recommendation: BAS40TWQ-7-F

The BAS40TWQ-7-F is a parametric equivalent from Diodes Incorporated with active product status and automotive-grade qualification (AEC-Q101). This part is electrically and mechanically identical to the BAS40TW-7 and includes automotive qualification for applications requiring this certification. Selection of this variant is appropriate for automotive and mission-critical applications where AEC-Q101 compliance is specified.

Alternative Recommendation: BAS40TW-TP

The BAS40TW-TP is manufactured by Micro Commercial Co and maintains full electrical and mechanical equivalence to the BAS40TW-7. This part is active and available in Tape & Reel packaging. Selection of this alternative provides supply chain diversification through a different manufacturer while maintaining identical performance characteristics.

Alternative Recommendation: BAS40TW_R1_00001

The BAS40TW_R1_00001 is manufactured by Panjit International Inc. and maintains full electrical and mechanical equivalence to the BAS40TW-7. This part is active and available in Tape & Reel packaging. Selection of this alternative provides supply chain diversification through a different manufacturer while maintaining identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can BAS40TW-7-F be used as a direct replacement for BAS40TW-7?

A: Yes. The BAS40TW-7-F is a parametric equivalent with identical electrical specifications, package configuration, and compliance status. The only difference is packaging format (Tape & Reel versus bulk), which does not affect electrical performance or board-level compatibility.

Q: What is the difference between BAS40TW-7-F and BAS40TWQ-7-F?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The BAS40TWQ-7-F includes automotive-grade qualification (AEC-Q101) and is designated for automotive applications. Selection depends on whether automotive qualification is required for the application.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the 6-TSSOP, SC-88, SOT-363 package configuration, ensuring identical board-level footprint and pin compatibility.

Q: Why is the BAS40TW-7 discontinued?

A: The BAS40TW-7 is discontinued at DiGi Electronics. Active equivalent alternatives are available from multiple manufacturers, including Diodes Incorporated, Micro Commercial Co, and Panjit International Inc.

Q: Can I use BAS40TW_R1_00001 or BAS40TW-TP in place of BAS40TW-7?

A: Yes. Both BAS40TW_R1_00001 and BAS40TW-TP are parametric equivalents with identical electrical specifications and package configuration. These parts provide supply chain alternatives from different manufacturers while maintaining full compatibility.

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

A: Substitution eligibility is determined by equivalence across diode configuration (3 Independent), technology (Schottky), reverse voltage rating (40 V), rectified current (200 mA DC per diode), forward voltage (1 V @ 40 mA), reverse recovery time (5 ns), operating temperature range (-55°C ~ 125°C), package type (6-TSSOP, SC-88, SOT-363), and compliance status (ROHS3 Compliant, MSL 1).

Q: Does packaging format (Tape & Reel versus bulk) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and handling. Electrical performance and board-level compatibility remain identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original BAS40TW-7 specifications.
