Engineering Selection Recommendations

BAV70W,115 (Nexperia USA Inc.)

The BAV70W,115 is a direct electrical equivalent to the BAV70W/MIF with identical specifications across all critical parameters: 100 V reverse voltage, 175 mA average rectified current, 1.25 V forward voltage, 4 ns reverse recovery time, and 500 nA reverse leakage current. The part carries active product status and is available in Tape & Reel packaging. This part is suitable for direct substitution in applications where the BAV70W/MIF is specified, provided that automotive qualification and AEC-Q101 compliance are not mandatory design requirements.

BAV70W,135 (Nexperia USA Inc.)

The BAV70W,135 is a parametric equivalent to the BAV70W/MIF with identical electrical specifications and active product status. This part maintains the same 100 V reverse voltage, 175 mA average rectified current, forward voltage, and reverse recovery time characteristics. The BAV70W,135 is available in Tape & Reel packaging and is suitable for direct substitution in applications where the BAV70W/MIF is specified, provided that automotive qualification and AEC-Q101 compliance are not mandatory design requirements.

SBAV70WT1G (onsemi)

The SBAV70WT1G is a similar part from onsemi that meets or exceeds the electrical requirements of the BAV70W/MIF. The device maintains the same 100 V reverse voltage rating and forward voltage characteristics, with a higher average rectified current rating of 200 mA per diode (compared to 175 mA). The reverse recovery time is 6 ns (compared to 4 ns), and reverse leakage current is 1 µA at 100 V (compared to 500 nA at 80 V). The SBAV70WT1G carries active product status, automotive grade qualification, and AEC-Q101 certification, matching the compliance profile of the BAV70W/MIF. This part is suitable for substitution in automotive applications requiring AEC-Q101 qualification and is available in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

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

A: Yes. The BAV70W,115 is electrically identical to the BAV70W/MIF across all specified parameters, including reverse voltage, average rectified current, forward voltage, reverse recovery time, and reverse leakage current. Both parts use the same SC-70, SOT-323 package and surface mount configuration. The primary difference is product status: BAV70W,115 is active while BAV70W/MIF is obsolete. Substitution is valid for applications where automotive qualification is not a design requirement.

Q: What is the difference between BAV70W,115 and BAV70W,135?

A: Both parts are electrically identical to the BAV70W/MIF with the same 100 V reverse voltage, 175 mA average rectified current, 1.25 V forward voltage, 4 ns reverse recovery time, and 500 nA reverse leakage current. The difference lies in packaging designation and inventory availability. Both are suitable for direct substitution.

Q: Can SBAV70WT1G replace BAV70W/MIF in automotive applications?

A: Yes. The SBAV70WT1G meets or exceeds the electrical requirements of the BAV70W/MIF and carries automotive grade qualification with AEC-Q101 certification, matching the compliance profile of the original part. The SBAV70WT1G has a higher average rectified current rating (200 mA versus 175 mA), making it suitable for applications with higher current demands. The reverse recovery time is 6 ns compared to 4 ns, and reverse leakage current is specified at 1 µA at 100 V. These differences do not preclude substitution in automotive designs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (BAV70W,115, BAV70W,135, and SBAV70WT1G) are ROHS3 compliant, matching the compliance status of the BAV70W/MIF.

Q: What is the package compatibility between BAV70W/MIF and substitute parts?

A: All substitute parts use the SC-70, SOT-323 package with surface mount configuration, ensuring mechanical and footprint compatibility with the BAV70W/MIF. No PCB layout modifications are required for substitution.

Q: Which substitute part is recommended for new automotive designs?

A: The SBAV70WT1G from onsemi is recommended for new automotive designs requiring AEC-Q101 qualification. This part carries active product status, automotive grade designation, and AEC-Q101 certification. The higher average rectified current rating (200 mA) provides additional design margin for current-limited applications.

Q: What is the difference in reverse leakage current between BAV70W/MIF and SBAV70WT1G?

A: The BAV70W/MIF specifies 500 nA reverse leakage current at 80 V, while the SBAV70WT1G specifies 1 µA at 100 V. The SBAV70WT1G measurement is taken at a higher voltage (100 V versus 80 V), which typically results in higher leakage current values. This difference does not preclude substitution in standard applications.
