Substitute Part Grouping Explanation

Substitution eligibility for the BAS70W-05-7 is determined by the following critical parameters:

Mandatory Matching Parameters:

  • Diode Configuration: 1 Pair Common Cathode
  • Technology: Schottky
  • Voltage - DC Reverse (Vr) (Max): 70 V
  • Current - Average Rectified (Io) (per Diode): 70 mA (DC)
  • Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
  • Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
  • Operating Temperature - Junction (Max): 150°C
  • Mounting Type: Surface Mount
  • Moisture Sensitivity Level (MSL): 1 (Unlimited)

Package Compatibility: Substitutes are grouped into two package categories:

  • SOT-323 Package Group: Direct mechanical and electrical equivalents maintaining identical footprint and pinout

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): BAS70W-05-7-F from Diodes Incorporated is the primary substitute. This part maintains identical electrical specifications and package form factor (SC-70, SOT-323) as the original BAS70W-05-7. The primary distinction is product status (Active vs. Discontinued) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). This part is suitable for direct PCB substitution without layout modification.

Secondary Substitutes (SOT-323 Package): BAS7005WH6327XTSA1 (Infineon Technologies), BAS70-05W,115 (Nexperia USA Inc.), BAS70-05W,135 (Nexperia USA Inc.), and BAS70-05WFILM (STMicroelectronics) are functionally equivalent alternatives in the SOT-323 package. All are Active products with ROHS3 compliance. These parts maintain identical mechanical footprint and electrical performance within specified parameters.

Alternative Substitute (SOT-23 Package): BAS7005E6327HTSA1 from Infineon Technologies provides functional equivalence with a different surface mount package (TO-236-3, SC-59, SOT-23-3). This part requires PCB layout modification due to different package dimensions and pinout spacing. Selection of this part is appropriate only when PCB redesign is feasible or when SOT-23 package availability is prioritized.

Compliance Consideration: All substitute parts listed are ROHS3 compliant, addressing regulatory requirements that may not be met by the original discontinued part. Selection should account for end-product compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can BAS70W-05-7-F be used as a direct replacement for BAS70W-05-7?

A: Yes. BAS70W-05-7-F is a direct replacement. Both parts share identical electrical specifications (70 V reverse voltage, 70 mA average rectified current, 1 V forward voltage at 15 mA) and package form factor (SC-70, SOT-323). The primary differences are product status (Active vs. Discontinued) and RoHS compliance (ROHS3 vs. non-compliant). No PCB layout modification is required.

Q: What is the difference between the SOT-323 and SOT-23 package options?

A: SOT-323 and SOT-23 are distinct surface mount packages with different physical dimensions and lead spacing. SOT-323 is smaller and more compact than SOT-23. Substitutes using SOT-23 package (BAS7005E6327HTSA1) require PCB footprint redesign. Substitutes using SOT-323 package (BAS70W-05-7-F, BAS7005WH6327XTSA1, BAS70-05W,115, BAS70-05W,135, BAS70-05WFILM) are mechanically compatible without layout modification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original BAS70W-05-7 is RoHS non-compliant. If end-product RoHS compliance is required, any of the listed substitutes satisfy this requirement.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time is provided for BAS70W-05-7 (5 ns), BAS7005WH6327XTSA1 (100 ps), and BAS7005E6327HTSA1 (100 ps). Faster reverse recovery time (lower trr value) indicates improved switching performance. The Infineon parts demonstrate superior switching characteristics. For applications requiring high-speed switching, Infineon alternatives are preferred. For standard rectification applications, all parts are functionally equivalent.

Q: What is the difference between reverse leakage current specifications?

A: The original BAS70W-05-7 specifies 100 nA @ 50 V reverse leakage. Nexperia and STMicroelectronics substitutes specify 10 µA @ 70 V. Infineon substitutes specify 100 nA @ 50 V. Higher reverse leakage current indicates greater leakage at rated voltage. For applications sensitive to leakage current, Infineon and Diodes Incorporated parts (100 nA specification) are preferred over Nexperia and STMicroelectronics alternatives (10 µA specification).

Q: Can I use BAS70-05W,115 and BAS70-05W,135 interchangeably?

A: Yes. Both Nexperia parts (BAS70-05W,115 and BAS70-05W,135) share identical electrical specifications and package form factor. The designation difference reflects internal Nexperia product coding. Both are functionally equivalent and interchangeable for the BAS70W-05-7 application.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in the following packaging formats: Tape & Reel (TR) for BAS70W-05-7-F, BAS7005WH6327XTSA1, BAS70-05W,115, and BAS70-05W,135; Cut Tape (CT) & Digi-Reel® for BAS70-05WFILM and BAS7005E6327HTSA1. Packaging selection depends on procurement volume and assembly process requirements.
