Forward voltage characteristics must be compatible with circuit operation

Mechanical Compatibility Requirements:

Mounting type must be surface mount
Package must be TO-236-3, SC-59, SOT-23-3 or equivalent footprint (SOT-323 represents a different footprint and is listed as an alternative for space-constrained applications)

Engineering Selection Recommendations

Direct Electrical Equivalents (Upgraded Current Rating):

The BAS7006E6327HTSA1 (Infineon, Cut Tape packaging) and BAS7006E6433HTMA1 (Infineon, Tape & Reel packaging) are direct functional equivalents with enhanced current capacity (70 mA vs. 15 mA). Both maintain identical voltage ratings, common anode configuration, and SOT-23-3 footprint compatibility. These components are active products with ROHS3 compliance and unlimited MSL rating. The Infineon variants feature lower reverse leakage current (100 nA @ 50 V) compared to the original specification.

Standard Footprint Alternatives (SOT-23-3):

The BAS70-06,215 (Nexperia, Cut Tape & Digi-Reel) and BAS70-06FILM (STMicroelectronics, Cut Tape & Digi-Reel) maintain identical package footprint and electrical specifications with 70 mA current rating. Both are active products with ROHS3 compliance. The BAS70-06-TP (Micro Commercial Co, Tape & Reel) provides equivalent performance with 70 mA rating and active product status, though with a maximum junction temperature of 125°C compared to 150°C for other alternatives.

Compact Footprint Alternative (SOT-323):

The BAS70-06W,115 (Nexperia, Tape & Reel) provides electrical equivalence with a smaller SC-70/SOT-323 footprint. This component is suitable for space-constrained applications requiring the same electrical performance. PCB layout modification is required for this footprint change.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and unlimited MSL rating, ensuring compatibility with current manufacturing and environmental standards. Nexperia components demonstrate the highest inventory availability (180,300 units for BAS70-06,215), followed by STMicroelectronics (23,100 units for BAS70-06FILM).

Frequently Asked Questions (FAQ)

Q: Can BAS7006TC be directly replaced with BAS70-06,215?

A: Yes. The BAS70-06,215 maintains identical voltage rating (70 V), common anode configuration, and SOT-23-3 footprint. The upgraded current rating (70 mA vs. 15 mA) provides enhanced capability without circuit incompatibility. Both components are ROHS3 compliant with unlimited MSL rating.

Q: What is the difference between the Infineon BAS7006E6327HTSA1 and BAS7006E6433HTMA1?

A: Both Infineon variants are electrically identical with 70 V rating and 70 mA current capacity. The primary difference is packaging: BAS7006E6327HTSA1 is supplied in Cut Tape (CT), while BAS7006E6433HTMA1 is supplied in Tape & Reel (TR). Selection depends on procurement and assembly requirements.

Q: Is the BAS70-06W,115 compatible with existing PCB layouts designed for BAS7006TC?

A: The BAS70-06W,115 uses a different footprint (SC-70/SOT-323 vs. SOT-23-3). PCB layout modification is required. This component is suitable only for new designs or boards with SOT-323 pad patterns.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) diode configuration (1 pair common anode), (2) Schottky technology, (3) DC reverse voltage ≥ 70 V, (4) average rectified current ≥ 15 mA per diode, and (5) surface mount package type. All listed substitutes meet these criteria.

Q: Why do substitute parts have higher current ratings (70 mA vs. 15 mA)?

A: The substitute parts represent current production equivalents from major manufacturers. The 70 mA rating provides enhanced performance margin and is standard for modern Schottky diode array designs. Circuits designed for 15 mA operation function without modification at the higher rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with unlimited MSL rating (1), meeting current environmental and manufacturing standards.

Q: Which substitute offers the best inventory availability?

A: The BAS70-06,215 (Nexperia) offers the highest inventory availability at 180,300 units. STMicroelectronics BAS70-06FILM provides 23,100 units. Infineon variants offer 6,100 units (BAS7006E6327HTSA1) and 866 units (BAS7006E6433HTMA1).

Q: Can BAS70-06-TP be used in high-temperature applications?

A: The BAS70-06-TP has a maximum junction temperature of 125°C, compared to 150°C for most other substitutes. For applications requiring operation above 125°C, alternative substitutes with 150°C maximum rating are recommended.

Q: What packaging options are available for SOT-23-3 footprint compatibility?

A: For SOT-23-3 footprint applications, available packaging options include Cut Tape (CT), Tape & Reel (TR), and Cut Tape & Digi-Reel combinations. Selection depends on assembly process requirements and procurement volume.
