Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAV70W,135 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Parametric Equivalents):

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 100 V or greater
• Current - Average Rectified (Io) (per Diode): 175 mA or greater
• Package / Case: SC-70, SOT-323 (identical footprint)
• Mounting Type: Surface Mount

Secondary Substitution Criteria (Direct Manufacturer Alternatives):

• Voltage - DC Reverse (Vr) (Max): 100 V or greater
• Current - Average Rectified (Io) (per Diode): 175 mA or greater
• Package / Case: SC-70, SOT-323 or compatible surface mount package
• Diode Configuration: 1 Pair Common Cathode

Tertiary Substitution Criteria (Similar Alternatives):

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 75 V or greater (reduced voltage rating)
• Current - Average Rectified (Io) (per Diode): 150 mA or greater (reduced current rating)
• Package / Case: SC-70, SOT-323 or TO-236-3, SC-59, SOT-23-3 (alternative surface mount packages)
• Mounting Type: Surface Mount

Parts are grouped based on the degree of parametric alignment with the main part. Parametric equivalents maintain all critical electrical specifications. Direct manufacturer alternatives provide equal or superior electrical performance with potential package variations. Similar alternatives provide reduced electrical ratings and may require application-level verification of suitability.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Recommended Primary Substitute):

BAV70W,115 (Nexperia USA Inc.) is the parametric equivalent to BAV70W,135. This part maintains identical electrical specifications across all critical parameters: 100 V reverse voltage, 175 mA average rectified current, 1.25 V forward voltage at 150 mA, and 4 ns reverse recovery time. Both parts are packaged in SC-70, SOT-323 and are ROHS3 compliant with MSL 1. The BAV70W,115 is currently Active in product status with significantly higher inventory availability (62,824 pcs vs. 9,930 pcs). This part provides direct functional replacement without application-level modifications.

Direct Manufacturer Alternative (Enhanced Performance):

BAV70WT1G (onsemi) provides superior current handling capability at 200 mA average rectified current per diode, compared to the 175 mA specification of BAV70W,135. The reverse voltage rating remains at 100 V, and forward voltage characteristics are identical. The reverse recovery time is 6 ns, which is acceptable for small signal applications. Package footprint is SC-70, SOT-323, maintaining PCB compatibility. This part is Active in product status with the highest inventory availability (305,300 pcs). Selection of this part is appropriate when application margins permit the slightly increased reverse recovery time.

Similar Alternatives (Reduced Ratings):

BAV70W-7-F (Diodes Incorporated) and BAV70WT-TP (Micro Commercial Co) both provide reduced electrical specifications with 75 V reverse voltage and 150 mA average rectified current. Both maintain the SC-70, SOT-323 package footprint and are Active in product status. These parts are suitable only for applications where the reduced voltage and current ratings are acceptable.

BAV70-TP (Micro Commercial Co) and BAV70E6433HTMA1 (Infineon Technologies) utilize alternative surface mount packages (TO-236-3, SC-59, SOT-23-3). These parts require PCB layout modifications and are not recommended as direct substitutes without design review. BAV70E6433HTMA1 is in Last Time Buy status and should not be selected for new designs.

Compliance and Certification:

All recommended substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, consistent with the primary part. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0070.

Frequently Asked Questions (FAQ)

Q: Can BAV70W,115 be used as a direct replacement for BAV70W,135?

A: Yes. BAV70W,115 is a parametric equivalent with identical electrical specifications and package. Both parts are manufactured by Nexperia USA Inc. in SC-70, SOT-323 package with 100 V reverse voltage, 175 mA average rectified current, and 4 ns reverse recovery time. No circuit modifications are required.

Q: What is the difference between BAV70WT1G and BAV70W,135?

A: BAV70WT1G provides higher average rectified current (200 mA vs. 175 mA) and is manufactured by onsemi rather than Nexperia. Both parts operate at 100 V reverse voltage and use the SC-70, SOT-323 package. The reverse recovery time of BAV70WT1G is 6 ns compared to 4 ns for BAV70W,135. This part is suitable for applications requiring higher current capacity.

Q: Why are BAV70-TP and BAV70W-7-F listed as similar alternatives rather than direct substitutes?

A: These parts have reduced electrical ratings (75 V reverse voltage and 150 mA average rectified current) compared to the 100 V and 175 mA specifications of BAV70W,135. While both maintain the SC-70, SOT-323 package footprint, the reduced voltage and current ratings limit their use to applications with lower electrical requirements. Selection requires application-level verification.

Q: Can I use BAV70E6433HTMA1 as a substitute?

A: BAV70E6433HTMA1 is not recommended for new designs. Although it provides 200 mA average rectified current, it has a reduced reverse voltage rating of 80 V and uses an alternative package (TO-236-3, SC-59, SOT-23-3) requiring PCB layout changes. Additionally, this part is in Last Time Buy status, indicating end-of-life status.

Q: What is the significance of the package designation SC-70, SOT-323 versus TO-236-3, SC-59, SOT-23-3?

A: SC-70, SOT-323 and TO-236-3, SC-59, SOT-23-3 are different surface mount package footprints. Parts using SC-70, SOT-323 are directly interchangeable on PCBs designed for this package. Parts using TO-236-3, SC-59, SOT-23-3 require different PCB land patterns and cannot be used without design modifications. BAV70W,135 uses SC-70, SOT-323; therefore, substitutes should use the same package unless PCB redesign is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, consistent with BAV70W,135. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0070.

Q: What inventory considerations should I evaluate?

A: BAV70W,115 has significantly higher inventory (62,824 pcs) compared to BAV70W,135 (9,930 pcs). BAV70WT1G has the highest availability (305,300 pcs). For applications where electrical specifications permit, higher inventory availability may reduce procurement lead times and costs.

Q: Can I substitute BAV70WT-TP for BAV70W,135 in a high-voltage application?

A: No. BAV70WT-TP has a maximum reverse voltage rating of 75 V, which is insufficient for applications requiring the 100 V rating of BAV70W,135. Using this part in a 100 V application would result in device failure or degraded performance.
