Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70-05-7 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Diode configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V minimum
• Current - Average Rectified (Io) (per Diode): 70 mA minimum
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA maximum
• Speed classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3 (primary) or SC-70, SOT-323 (alternative form factor)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are classified into two categories:

Category 1: Direct SOT-23-3 Package Equivalents — Parts maintaining identical package form factor with matching or superior electrical specifications and active product status.

Category 2: Alternative Package Form Factor — Parts with identical electrical specifications but different surface mount package (SOT-323) requiring PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Identical Package, Active Status):

BAS70-05-7-F (Diodes Incorporated) is the direct parametric equivalent with identical electrical specifications and package form factor. This part maintains the same junction temperature rating as the original and carries ROHS3 compliance certification. Inventory availability is 8,184 units.

BAS70-05-TP (Micro Commercial Co) provides identical electrical specifications and package compatibility with the highest inventory availability at 248,307 units. This part is ROHS3 compliant and suitable for high-volume production requirements.

BAS70-05FILM (STMicroelectronics) offers identical electrical specifications with enhanced junction temperature rating (150°C maximum) and ROHS3 compliance. Inventory availability is 20,300 units.

Secondary Substitutes (Identical Package, Enhanced Specifications):

BAS7005E6327HTSA1 (Infineon Technologies), BAS70-05,215 (NXP USA Inc.), and BAS70-05,235 (Nexperia USA Inc.) all provide 70 V / 70 mA specifications with enhanced maximum junction temperature of 150°C. These parts are suitable for applications requiring extended thermal operating range. All three maintain SOT-23-3 package compatibility.

Alternative Package Form Factor (SOT-323):

BAS70-05W,115 and BAS70-05W,135 (both Nexperia USA Inc.) provide identical electrical specifications in the smaller SC-70 / SOT-323 package. These parts require PCB layout modification and are suitable for space-constrained applications. Both carry ROHS3 compliance and 150°C maximum junction temperature rating.

Compliance Considerations:

All recommended substitute parts carry ROHS3 compliance certification. The original BAS70-05-7 is RoHS non-compliant; substitution with any recommended part improves regulatory compliance posture for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can BAS70-05-7-F be used as a direct replacement for BAS70-05-7?

A: Yes. BAS70-05-7-F is a parametric equivalent with identical electrical specifications (70 V, 70 mA, 1 V forward voltage) and identical SOT-23-3 package form factor. The primary difference is active product status and ROHS3 compliance certification. No circuit modifications are required.

Q: What is the difference between BAS70-05-7 and the Infineon BAS7005E6327HTSA1?

A: Both parts meet the 70 V / 70 mA electrical specification and share the SOT-23-3 package. The Infineon part features a maximum junction temperature of 150°C compared to 125°C for the original, providing enhanced thermal performance. Reverse recovery time differs (100 ps vs. 5 ns), but both meet small signal switching requirements. The Infineon part is ROHS3 compliant and actively manufactured.

Q: Are the SOT-323 package alternatives (BAS70-05W,115 and BAS70-05W,135) pin-compatible with the original BAS70-05-7?

A: No. SOT-323 and SOT-23-3 are different package form factors with different pin configurations and PCB footprints. While electrical specifications are identical, PCB layout modification is required for substitution. SOT-323 is a smaller package suitable for space-constrained designs.

Q: Which substitute part has the highest inventory availability?

A: BAS70-05-TP (Micro Commercial Co) has the highest inventory availability at 248,307 units. This part is ROHS3 compliant, maintains SOT-23-3 package compatibility, and meets all electrical specifications of the original BAS70-05-7.

Q: Do all substitute parts meet RoHS compliance requirements?

A: All recommended substitute parts carry ROHS3 compliance certification. The original BAS70-05-7 is RoHS non-compliant. Substitution with any recommended part satisfies RoHS compliance requirements for new designs and manufacturing.

Q: What is the significance of the reverse recovery time (trr) difference between parts?

A: Reverse recovery time affects switching speed in high-frequency applications. The original BAS70-05-7 and several substitutes (BAS70-05-7-F, BAS70-05 RFG, BAS70-05-TP) specify 5 ns trr. The Infineon BAS7005E6327HTSA1 specifies 100 ps, indicating faster switching capability. For small signal applications ≤ 200 mA, both specifications are acceptable. Selection depends on specific circuit switching frequency requirements.

Q: Can BAS70-05FILM be used in applications requiring extended temperature operation?

A: Yes. BAS70-05FILM features a maximum junction temperature of 150°C compared to 125°C for the original BAS70-05-7. This part is suitable for applications requiring extended thermal operating range while maintaining identical electrical specifications and SOT-23-3 package compatibility.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel® for high-volume automated assembly, Tape & Reel (TR) for production runs, and standard packaging. Selection depends on manufacturing process requirements and volume specifications.
