BAS40TWQ-7-F Equivalent & Substitute Parts

Part Overview

The BAS40TWQ-7-F is a Schottky diode array manufactured by Diodes Incorporated, configured as three independent diodes in a 6-TSSOP (SOT-363) surface mount package. This component is designed for applications requiring low forward voltage drop and fast switching characteristics at moderate current levels. The part is classified as Active product status with AEC-Q101 automotive qualification and full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources and package variants may be required due to inventory availability, supply chain considerations, or design revision updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAS40TWQ-7-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode configuration: 3 Independent
• Technology: Schottky
• Voltage rating (Vr): 40 V maximum
• Current rating (Io): 200 mA per diode
• Forward voltage (Vf): 1 V maximum at 40 mA
• Reverse recovery time (trr): 5 ns
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package type: 6-TSSOP, SC-88, SOT-363
• Mounting type: Surface Mount
• Supplier device package: SOT-363

Compliance Parameters (Must Match):

• RoHS3 compliance
• REACH unaffected status

Substitute parts identified in this reference maintain all specified electrical and mechanical parameters. Variations in reverse leakage current (Ir) and moisture sensitivity level (MSL) do not disqualify substitution when all primary parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

BAS40TW-7-F (Diodes Incorporated): This part is a direct parametric equivalent to the BAS40TWQ-7-F, manufactured by the same supplier. Both parts maintain identical electrical specifications, package configuration, and compliance certifications. The BAS40TW-7-F carries Active product status and is suitable for direct substitution in all applications where the BAS40TWQ-7-F is specified. Higher inventory availability (9205 units) supports supply chain continuity.

BAS40TW_R1_00001 (Panjit International Inc.): This part is a cross-manufacturer equivalent produced by Panjit International Inc. All critical electrical parameters, package type, and compliance requirements are maintained. The reverse leakage current specification differs (1 µA @ 25 V versus 200 nA @ 30 V), but this variation does not affect substitution eligibility as both values remain within acceptable operating margins for Schottky diode arrays in this class. Active product status and full RoHS3 compliance confirm suitability for direct substitution. This option provides supply diversification across multiple manufacturers.

Both substitute parts are qualified for automotive applications and maintain the full operating temperature range required for the original specification.

Frequently Asked Questions (FAQ)

Q: Can BAS40TW-7-F be used as a direct replacement for BAS40TWQ-7-F?

A: Yes. Both parts are manufactured by Diodes Incorporated and maintain identical electrical parameters, package configuration (6-TSSOP, SOT-363), and compliance certifications. Direct substitution is supported without circuit modification.

Q: Is the Panjit BAS40TW_R1_00001 compatible with the original BAS40TWQ-7-F design?

A: Yes. The Panjit part maintains all critical electrical specifications including 40 V reverse voltage rating, 200 mA per-diode current rating, 1 V forward voltage at 40 mA, and 5 ns reverse recovery time. Package type and mounting configuration are identical. The difference in reverse leakage current specification does not prevent substitution.

Q: Are there any package or pinout differences between these three parts?

A: No. All three parts use the 6-TSSOP (SOT-363) surface mount package with identical pinout and mechanical dimensions. PCB layout and assembly processes require no modification.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 compliant and REACH unaffected. The original BAS40TWQ-7-F carries AEC-Q101 automotive qualification; equivalent automotive-grade status applies to the substitute parts.

Q: Does reverse leakage current variation affect circuit performance?

A: The BAS40TW_R1_00001 specifies 1 µA reverse leakage at 25 V, compared to 200 nA at 30 V for the Diodes Incorporated parts. Both specifications are within acceptable operating parameters for Schottky diode arrays in this current class and do not impact substitution eligibility.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across the junction temperature range of -55°C to 125°C, supporting the full specification envelope of the original design.
