BAS70TW-7 Equivalent & Substitute Parts

Part Overview

The BAS70TW-7 is a Schottky diode array containing three independent diodes rated for 70 V DC reverse voltage and 70 mA average rectified current per diode. Manufactured by Diodes Incorporated, this component is packaged in a 6-TSSOP (SOT-363) surface mount configuration. The BAS70TW-7 is discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts that maintain identical electrical and mechanical specifications for continued circuit design and production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70TW-7 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Diode configuration: 3 Independent
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io) (per Diode): 70 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 50 V
• Operating Temperature - Junction: -55°C ~ 125°C

Mechanical Parameters (Must Match Exactly):

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

Substitute parts may differ in packaging format (bulk versus tape & reel), product status (active versus discontinued), RoHS compliance status, and manufacturer identity, provided all electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—BAS70TW-7-F, BAS70TWQ-7-F, and BAS70TW-TP—are electrically and mechanically equivalent to the BAS70TW-7 and are suitable for direct substitution in circuit applications.

BAS70TW-7-F (Diodes Incorporated): This part maintains active product status and is ROHS3 compliant. It is available in tape & reel packaging format and represents the direct active equivalent from the original manufacturer.

BAS70TWQ-7-F (Diodes Incorporated): This part carries automotive grade designation and AEC-Q101 qualification, indicating suitability for automotive applications. It is ROHS3 compliant and available in tape & reel format with the highest inventory availability among all substitutes.

BAS70TW-TP (Micro Commercial Co): This part is manufactured by an alternative supplier and is ROHS3 compliant. It is available in tape & reel packaging format with substantial inventory availability.

Selection among these substitutes depends on application requirements, supply chain preferences, and compliance mandates. All three parts satisfy identical electrical and mechanical specifications for the BAS70TW-7.

Frequently Asked Questions (FAQ)

Q: Can BAS70TW-7-F be used as a direct replacement for BAS70TW-7?

A: Yes. The BAS70TW-7-F is electrically and mechanically equivalent to the BAS70TW-7. The primary difference is packaging format (tape & reel versus bulk) and active product status. Both parts share identical electrical specifications and SOT-363 package configuration.

Q: What is the difference between BAS70TW-7-F and BAS70TWQ-7-F?

A: Both parts are electrically and mechanically equivalent. The BAS70TWQ-7-F carries automotive grade designation and AEC-Q101 qualification, making it suitable for automotive applications. Selection between these parts depends on application requirements and compliance mandates.

Q: Is BAS70TW-TP from Micro Commercial Co compatible with the BAS70TW-7?

A: Yes. The BAS70TW-TP is electrically and mechanically equivalent to the BAS70TW-7. The manufacturer differs, but all electrical parameters, mechanical specifications, and package configuration are identical.

Q: Does the packaging format (bulk versus tape & reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: The BAS70TW-7 is RoHS non-compliant. All three substitute parts—BAS70TW-7-F, BAS70TWQ-7-F, and BAS70TW-TP—are ROHS3 compliant. This represents an improvement in environmental compliance for new designs or production runs.

Q: Can BAS70TWQ-7-F be used in non-automotive applications?

A: Yes. The BAS70TWQ-7-F meets all electrical and mechanical specifications for the BAS70TW-7 and is suitable for any application within these parameters. Automotive qualification does not restrict use in other applications.

Q: What is the significance of the SOT-363 package designation?

A: SOT-363 is the standardized package designation for this diode array configuration. All substitute parts use this identical package, ensuring pin-for-pin compatibility and identical PCB footprint requirements.
