Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40DW-04-7 is determined by strict equivalence across the following critical parameters:

• Diode Configuration: 2 Pair Series Connection (electrical topology requirement)
• Technology: Schottky (determines forward voltage characteristics and switching speed)
• Voltage - DC Reverse (Vr) (Max): 40 V (maximum blocking voltage specification)
• Current - Average Rectified (Io) (per Diode): 200 mA (DC) (current handling capacity)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA (forward conduction specification)
• Reverse Recovery Time (trr): 5 ns (switching performance parameter)
• Operating Temperature - Junction: -55°C ~ 125°C (thermal operating range)
• Package / Case: 6-TSSOP, SC-88, SOT-363 (physical and electrical footprint compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (handling and storage requirements)

All identified substitute parts maintain identical specifications across these parameters, ensuring direct functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: BAS40DW-04-7-F

The BAS40DW-04-7-F, manufactured by Diodes Incorporated, is the preferred substitute. This part maintains identical electrical and mechanical specifications to the BAS40DW-04-7 while offering active product status and ROHS3 compliance. The part is available in Tape & Reel (TR) packaging with 2950 units in stock, supporting production volume requirements.

Secondary Recommendation: BAS40BRW-7-F

The BAS40BRW-7-F, also from Diodes Incorporated, provides equivalent functionality with active product status and ROHS3 compliance. This part is supplied in Cut Tape (CT) & Digi-Reel® packaging with 2000 units available, suitable for lower-volume applications or mixed packaging requirements.

Alternative Recommendation: BAS40DW-04-TP

The BAS40DW-04-TP, manufactured by Micro Commercial Co, delivers identical electrical specifications and active product status with ROHS3 compliance. This part offers the highest inventory availability at 26681 units in Tape & Reel (TR) packaging, providing supply chain flexibility.

Alternative Recommendation: BAS40SDW_R1_00001

The BAS40SDW_R1_00001, manufactured by Panjit International Inc., maintains all critical electrical and mechanical parameters with active product status and ROHS3 compliance. This part is available in Tape & Reel (TR) packaging with the largest inventory at 318727 units, offering maximum supply assurance.

All substitute parts are ROHS3 compliant, addressing the non-compliance status of the discontinued BAS40DW-04-7. Selection among active alternatives should be based on packaging format requirements, inventory availability, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the BAS40DW-04-7-F be used as a direct replacement for the BAS40DW-04-7?

A: Yes. The BAS40DW-04-7-F is a direct parametric equivalent with identical electrical specifications (40 V reverse voltage, 200 mA average rectified current, 1 V forward voltage at 40 mA, 5 ns reverse recovery time) and mechanical compatibility (6-TSSOP SOT-363 package, surface mount). The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between the packaging options (CT, TR, TP)?

A: Cut Tape (CT) & Digi-Reel® packaging is suitable for lower-volume or manual assembly processes. Tape & Reel (TR) and TP packaging are designed for automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements and volume specifications.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 6-TSSOP, SC-88, SOT-363 package with identical pin configuration and land pattern. No PCB redesign is required for substitution.

Q: Why is ROHS3 compliance important for this substitution?

A: The original BAS40DW-04-7 is RoHS non-compliant. All active substitute parts are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution in regulated markets.

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

A: The BAS40DW-04-7, BAS40BRW-7-F, BAS40DW-04-7-F, and BAS40DW-04-TP specify 200 nA @ 30 V reverse leakage current. The BAS40SDW_R1_00001 specifies 1 µA @ 25 V. Both values are within acceptable operating parameters for Schottky diode arrays in this voltage and current class. The difference reflects measurement conditions rather than functional incompatibility.

Q: Is inventory availability a factor in part selection?

A: Inventory levels vary significantly among substitutes. The BAS40SDW_R1_00001 offers 318727 units, BAS40DW-04-TP offers 26681 units, BAS40DW-04-7-F offers 2950 units, and BAS40BRW-7-F offers 2000 units. Selection should account for production volume requirements and supply chain continuity objectives.

Q: Can these parts be used interchangeably in existing designs without circuit modification?

A: Yes. All substitute parts maintain identical electrical performance across voltage, current, temperature, and switching characteristics. No circuit modifications are required for direct substitution.
