Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS70W-06-7 is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode configuration (1 pair common anode)
• Technology type (Schottky)
• Maximum reverse voltage (70 V minimum)
• Average rectified current per diode (70 mA minimum)
• Forward voltage characteristics (1 V @ 15 mA)
• Small signal speed classification
• Maximum junction temperature (150°C)
• Surface mount packaging

Substitution Categories:

Parametric Equivalents maintain identical electrical specifications and package form factor (SOT-323). These parts are direct replacements with no design modifications required.

Direct Manufacturer Equivalents meet all electrical parameters but may originate from different manufacturers. Electrical performance is equivalent within specified tolerances.

Upgrade Parts meet or exceed all electrical specifications with improved performance characteristics (lower reverse leakage, faster recovery time) while maintaining package compatibility.

Manufacturer Recommended Parts provide functional equivalence with alternative package options (SOT-23 vs. SOT-323) suitable for designs with flexible PCB layout requirements.

All recommended substitutes are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can BAS70W-06-7-F be used as a direct replacement for BAS70W-06-7?

A: Yes. The BAS70W-06-7-F is a parametric equivalent with identical electrical specifications and package form factor. The primary difference is product status (active vs. discontinued) and RoHS compliance (RoHS3 vs. non-compliant). No design modifications are required.

Q: What is the difference between BAS70W-06-7-F and BAS7006WH6327XTSA1?

A: Both parts meet the same electrical specifications and use the same package (SC-70, SOT-323). The BAS7006WH6327XTSA1 features improved reverse recovery time (100 ps vs. 5 ns), providing faster switching performance. The BAS70W-06-7-F is manufactured by Diodes Incorporated, while BAS7006WH6327XTSA1 is manufactured by Infineon Technologies.

Q: Can BAW56WT-TP replace BAS70W-06-7?

A: Yes, with design margin improvement. The BAW56WT-TP exceeds all electrical specifications: 75 V reverse voltage (vs. 70 V), 150 mA average rectified current (vs. 70 mA), and 4 ns reverse recovery time (vs. 5 ns). The package form factor is identical (SC-70, SOT-323). This part is suitable for applications where enhanced performance margins are beneficial.

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

A: SOT-323 (SC-70) and SOT-23-3 (SC-59, TO-236-3) are both surface mount packages for the same diode array configuration. SOT-323 is smaller and more compact. SOT-23-3 is larger with different pin spacing. PCB layout modifications are required when switching between these packages. BAS7006E6327HTSA1 and BAS7006E6433HTMA1 use SOT-23-3 packaging.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts are RoHS3 compliant. The original BAS70W-06-7 is RoHS non-compliant. All active alternatives meet current regulatory requirements.

Q: Which substitute part has the lowest reverse leakage current?

A: The BAS70-06W,115 has the lowest reverse leakage current at 10 µA @ 70 V. The original BAS70W-06-7 specifies 100 nA @ 50 V. The BAS7006WH6327XTSA1 and Infineon SOT-23 variants specify 100 nA @ 50 V.

Q: Can I use BAS7006E6327HTSA1 in a design with SOT-323 footprint?

A: No. The BAS7006E6327HTSA1 uses SOT-23-3 packaging, which has different pin spacing and footprint dimensions compared to SOT-323. PCB layout modifications are required. If SOT-323 packaging is required, use BAS70W-06-7-F, BAS7006WH6327XTSA1, BAS70-06W,115, or BAW56WT-TP.

Q: What is the operating temperature range for these parts?

A: All parts specify a maximum junction temperature of 150°C. The BAW56WT-TP additionally specifies an operating temperature range of -55°C to 150°C. Consult individual datasheets for detailed thermal characteristics and derating curves.

Q: Which substitute part has the fastest reverse recovery time?

A: The BAS7006WH6327XTSA1, BAS7006E6327HTSA1, and BAS7006E6433HTMA1 all feature 100 ps reverse recovery time, which is faster than the original BAS70W-06-7 (5 ns). The BAW56WT-TP features 4 ns recovery time.
