Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS40-05V,115 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must be 2 Pair Common Cathode
• Technology must be Schottky
• Maximum DC reverse voltage (Vr) must be ≥ 40 V
• Average rectified current (Io) per diode must be ≥ 120 mA
• Forward voltage (Vf) must be ≤ 1 V @ 40 mA
• Speed classification must support Small Signal operation

Mechanical Compatibility Requirements:

• Mounting type must be Surface Mount
• Package must be compatible with SOT-563 or SOT-666 footprints or equivalent surface mount configurations

Compliance Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The substitute part BAS40DW-05-7-F meets all electrical and mechanical criteria for direct substitution while offering enhanced current rating and active product status.

Engineering Selection Recommendations

For Existing Designs (Maintenance and Repair): The BAS40-05V,115 remains available in inventory (4963 Pcs) and maintains full ROHS3 compliance and MSL 1 rating. This part is suitable for sustaining existing production and field repairs where the original specification is required.

For New Designs: The BAS40DW-05-7-F from Diodes Incorporated is the recommended substitute. This part carries Active product status, ensuring long-term availability and supply chain continuity. The substitute provides identical electrical performance at the specified operating point (1 V @ 40 mA forward voltage, 40 V reverse voltage) with enhanced current capacity (200 mA versus 120 mA per diode). Both parts maintain equivalent compliance certifications (ROHS3, MSL 1).

Package Consideration: The substitute part uses SOT-363 (6-TSSOP, SC-88) packaging versus the original SOT-666. PCB layout modifications are required for footprint compatibility. Both packages are standard surface mount configurations with established manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can BAS40DW-05-7-F directly replace BAS40-05V,115 without circuit modification?

A: Electrical substitution is valid without circuit modification. Both parts share identical diode configuration (2 Pair Common Cathode), reverse voltage rating (40 V), and forward voltage characteristics (1 V @ 40 mA). The substitute's higher current rating (200 mA versus 120 mA) provides additional design margin. PCB layout modification is required due to package differences (SOT-363 versus SOT-666).

Q: What is the significance of the higher current rating in BAS40DW-05-7-F?

A: The BAS40DW-05-7-F is rated for 200 mA average rectified current per diode compared to 120 mA in the original part. This higher rating provides increased thermal margin and allows operation at higher current levels without exceeding device limits. For applications operating at or below 120 mA, both parts perform identically.

Q: Are both parts compliant with current regulatory requirements?

A: Both the BAS40-05V,115 and BAS40DW-05-7-F are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both parts meet current environmental and handling standards.

Q: Why is the original part marked "Not For New Designs"?

A: The BAS40-05V,115 carries a "Not For New Designs" status, indicating the manufacturer has transitioned this product to end-of-life. The BAS40DW-05-7-F maintains Active status, ensuring continued manufacturing support and supply availability for new product development.

Q: What are the package footprint differences?

A: The BAS40-05V,115 uses SOT-666 packaging (6-pin surface mount), while the BAS40DW-05-7-F uses SOT-363 packaging (6-pin surface mount, also designated 6-TSSOP or SC-88). Both are 6-pin configurations but with different pin spacing and land patterns. PCB redesign is necessary for footprint compatibility.

Q: Are there any thermal or operating temperature differences?

A: The BAS40-05V,115 specifies a maximum junction temperature of 150°C. The BAS40DW-05-7-F specifies an operating temperature range of -55°C to 125°C. For applications within the -55°C to 125°C range, both parts are compatible. Applications requiring operation above 125°C require evaluation against the original part's 150°C maximum rating.
