Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAW56W/DG/B2F are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io) (per Diode): 150 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Reverse Recovery Time (trr): 4 ns
• Current - Reverse Leakage @ Vr: 500 nA @ 80 V
• Operating Temperature - Junction (Max): 150°C

Mechanical Parameters (Must Match):

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the BAW56W/DG/B2F.

Parameter Comparison

Engineering Selection Recommendations

Both BAW56W,115 and BAW56W,135 are direct electrical and mechanical equivalents to the BAW56W/DG/B2F. Selection between these substitutes is based on the following factors:

BAW56W,115:

• Manufactured by Nexperia USA Inc., the same manufacturer as the original part
• Active product status ensures long-term availability and supply chain continuity
• Available in Cut Tape (CT) and Digi-Reel® packaging options, suitable for both automated assembly and manual handling
• Inventory of 4300 units supports moderate to high-volume production requirements
• ROHS3 compliant

BAW56W,135:

• Manufactured by NXP Semiconductors, the parent company of Nexperia
• Active product status ensures long-term availability
• Available in Bulk packaging, optimized for high-volume manufacturing operations
• Inventory of 211085 units supports high-volume production requirements
• Provides maximum supply availability

Both parts satisfy automotive-grade requirements and AEC-Q101 qualification. Selection should be based on packaging requirements, volume needs, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can BAW56W,115 or BAW56W,135 be used as direct replacements for BAW56W/DG/B2F?

A: Yes. Both substitute parts are electrically and mechanically equivalent. They share identical electrical specifications including reverse voltage rating (90 V), forward voltage (1.25 V @ 150 mA), reverse recovery time (4 ns), and reverse leakage current (500 nA @ 80 V). Both are packaged in SC-70, SOT-323 surface mount configuration and meet AEC-Q101 automotive qualification.

Q: What is the difference between BAW56W,115 and BAW56W,135?

A: The primary differences are manufacturer designation and packaging format. BAW56W,115 is supplied by Nexperia USA Inc. in Cut Tape (CT) and Digi-Reel® formats. BAW56W,135 is supplied by NXP Semiconductors in Bulk format. Electrically and mechanically, both parts are identical and interchangeable.

Q: Are there any compliance or certification differences between the substitute parts?

A: Both substitute parts maintain AEC-Q101 automotive qualification and Moisture Sensitivity Level 1 (Unlimited). BAW56W,115 is explicitly ROHS3 compliant. BAW56W,135 RoHS status is not specified in available documentation. For applications requiring explicit ROHS3 compliance documentation, BAW56W,115 is the recommended selection.

Q: Which substitute part should be selected for high-volume production?

A: BAW56W,135 is recommended for high-volume production due to bulk packaging format and significantly higher inventory availability (211085 units). BAW56W,115 is suitable for moderate-volume applications with its Cut Tape and Digi-Reel® packaging options.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. Both BAW56W,115 and BAW56W,135 are automotive-grade components qualified to AEC-Q101 standard, identical to the original BAW56W/DG/B2F specification.

Q: What is the significance of the SOT-323 package designation?

A: SOT-323 is the industry-standard surface mount package for this diode array configuration. All three parts (original and substitutes) use this identical package, ensuring pin-for-pin compatibility and direct PCB layout compatibility without design modification.
