Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBD770DWT1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 2 Independent
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V
• Package / Case: 6-TSSOP, SC-88, SOT-363 (electrically and mechanically equivalent)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute Parts Identified:

1. MBD770DWT1G (onsemi) – Direct manufacturer equivalent with active product status
2. BAS70-07S,115 (Nexperia USA Inc.) – Functionally equivalent alternative with active product status

Both substitute parts maintain the same diode configuration, Schottky technology, 70V reverse voltage rating, and SOT-363 package compatibility. Both are RoHS3 compliant and carry identical MSL ratings.

Parameter Comparison

Engineering Selection Recommendations

MBD770DWT1G (onsemi) is the primary substitute for the obsolete MBD770DWT1. This part maintains manufacturer continuity with onsemi and provides direct functional equivalence. The MBD770DWT1G carries active product status and achieves ROHS3 compliance, addressing regulatory requirements that the original part does not meet.

BAS70-07S,115 (Nexperia USA Inc.) serves as a secondary substitute option. This part provides equivalent electrical performance within the specified 70V reverse voltage rating and maintains the same package footprint. The BAS70-07S,115 is also ROHS3 compliant and carries active product status.

Both substitute parts are suitable for direct replacement in applications where the MBD770DWT1 was originally specified, provided that the design accommodates the electrical characteristics of the selected substitute. The transition from RoHS non-compliant to ROHS3 compliant parts aligns with current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can MBD770DWT1G be used as a direct replacement for MBD770DWT1?

A: Yes. The MBD770DWT1G is a direct equivalent manufactured by onsemi with identical diode configuration (2 Independent), Schottky technology, 70V reverse voltage rating, and SOT-363 package. The primary difference is active product status and ROHS3 compliance.

Q: What are the key differences between MBD770DWT1G and BAS70-07S,115?

A: Both parts share the same diode configuration, Schottky technology, 70V reverse voltage rating, and SOT-363 package compatibility. The primary differences are manufacturer (onsemi vs. Nexperia USA Inc.) and specific electrical characteristics such as forward voltage and reverse leakage current specifications.

Q: Are the package dimensions identical between all three parts?

A: All three parts use the 6-TSSOP, SC-88, SOT-363 package designation, which ensures mechanical and electrical compatibility for PCB mounting and circuit integration.

Q: Does the transition from RoHS non-compliant to ROHS3 compliant parts affect circuit performance?

A: No. ROHS3 compliance addresses material composition and environmental standards, not electrical performance. The substitute parts maintain equivalent electrical characteristics for the specified application.

Q: What is the MSL rating significance for these parts?

A: All three parts carry an MSL rating of 1 (Unlimited), indicating unlimited shelf life without moisture absorption concerns. This simplifies storage and handling requirements.

Q: Can BAS70-07S,115 be substituted in designs originally specified for MBD770DWT1?

A: Yes. The BAS70-07S,115 meets all critical substitution criteria: 2 Independent diode configuration, Schottky technology, 70V reverse voltage rating, and SOT-363 package compatibility. Verification of specific electrical characteristics within the application circuit is necessary for final design validation.
