Engineering Selection Recommendations

Primary Part Selection: The SMD18PL-TP remains the primary selection for applications requiring 80V reverse voltage rating and 1A average rectified current capacity. This part is Active status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute Part Considerations: The BAS70H,115 is suitable for applications where the following conditions are met:

• Maximum reverse voltage requirement does not exceed 70V
• Average rectified current requirement does not exceed 70mA
• Forward voltage drop at reduced current levels is acceptable
• Small signal switching characteristics are sufficient for the application

Both parts share identical surface mount SOD-123F packaging, RoHS3 compliance status, and MSL 1 moisture sensitivity rating, enabling direct footprint compatibility on printed circuit boards.

The BAS70H,115 offers lower reverse leakage current (10 µA @ 70V versus 500 µA @ 80V) and higher maximum junction temperature rating (150°C versus 125°C), which may provide advantages in specific thermal or low-leakage applications within its electrical parameter limits.

Frequently Asked Questions (FAQ)

Q: Can the BAS70H,115 be used as a direct replacement for the SMD18PL-TP in all applications?

A: No. The BAS70H,115 has reduced voltage and current ratings. It is suitable only for applications where the reverse voltage does not exceed 70V and the average rectified current does not exceed 70mA. Applications requiring the full 80V and 1A specifications of the SMD18PL-TP require the primary part.

Q: Are the package dimensions identical between SMD18PL-TP and BAS70H,115?

A: Both parts use SOD-123F surface mount packaging. The SMD18PL-TP is supplied in SOD-123FL variant, while the BAS70H,115 is supplied in standard SOD-123F. Both are compatible with identical PCB footprints for surface mount assembly.

Q: What is the difference between Fast Recovery and Small Signal speed classifications?

A: The SMD18PL-TP is classified as Fast Recovery (≤ 500ns) for currents greater than 200mA. The BAS70H,115 is classified as Small Signal for currents up to 200mA with any speed characteristic. These classifications reflect different switching speed performance at their respective current ratings.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the SMD18PL-TP and BAS70H,115 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled without special moisture-barrier packaging or baking procedures prior to assembly.

Q: How do the reverse leakage current specifications compare?

A: The SMD18PL-TP exhibits 500 µA reverse leakage at 80V, while the BAS70H,115 exhibits 10 µA reverse leakage at 70V. The BAS70H,115 demonstrates significantly lower leakage current, which may be advantageous in precision analog or high-impedance circuit applications.

Q: What is the maximum junction temperature difference between these parts?

A: The SMD18PL-TP operates to a maximum junction temperature of 125°C, while the BAS70H,115 operates to 150°C. The BAS70H,115 provides a 25°C higher thermal margin, which may be beneficial in high-temperature environments.
