Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS70WT-04-TP are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match identically:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 70 V
• Current - Average Rectified (Io) (per Diode): 70 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 15 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 50 V
• Operating Temperature - Junction: -55°C ~ 125°C
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes for the BAS70WT-04-TP in applications where these specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both the BAS70WT-04-TP and BAS70W-04Q-7-F are active production components with full parametric equivalence across all specified electrical and mechanical characteristics. Selection between these parts is based on the following factors:

BAS70WT-04-TP (Micro Commercial Co): Suitable for general industrial applications. Current inventory: 837 pieces. ROHS3 compliant, REACH unaffected, MSL 1 (unlimited moisture sensitivity).

BAS70W-04Q-7-F (Diodes Incorporated): Qualified to AEC-Q101 automotive standard with grade designation. Current inventory: 9200 pieces. ROHS3 compliant, REACH unaffected, MSL 1 (unlimited moisture sensitivity). This part is appropriate for automotive and mission-critical applications requiring automotive-grade qualification.

Both parts are suitable for direct substitution in applications where the specified electrical ratings and operating temperature range are required. Selection should be based on supply availability, procurement lead time, and application-specific qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can BAS70W-04Q-7-F replace BAS70WT-04-TP in all applications?

A: Yes, BAS70W-04Q-7-F is a parametric equivalent with identical electrical specifications, reverse recovery time, leakage current, forward voltage, and operating temperature range. Both parts use the same SC-70, SOT-323 package and are surface mount compatible. The primary difference is that BAS70W-04Q-7-F carries AEC-Q101 automotive qualification, making it suitable for automotive applications where such certification is required.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the SC-70, SOT-323 package with identical mechanical specifications and surface mount mounting type. Pinout and footprint compatibility are guaranteed.

Q: What is the significance of AEC-Q101 qualification on the BAS70W-04Q-7-F?

A: AEC-Q101 is an automotive industry standard qualification that certifies the component for use in automotive applications. This qualification is required for automotive-grade designs but is not necessary for general industrial applications. The BAS70WT-04-TP does not carry this designation.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BAS70WT-04-TP and BAS70W-04Q-7-F are ROHS3 compliant and REACH unaffected.

Q: What is the difference in reverse recovery time between these parts?

A: There is no difference. Both parts have a reverse recovery time (trr) of 5 ns, classifying them as small signal diodes with any speed rating.

Q: Can I use these parts interchangeably in PCB designs?

A: Yes. Both parts are mechanically and electrically interchangeable. PCB footprints, solder pad layouts, and component placement are identical for both the BAS70WT-04-TP and BAS70W-04Q-7-F.
