BAT64AW-7-F Equivalent & Substitute Parts

Part Overview

The BAT64AW-7-F is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Anode device in a surface mount SC-70, SOT-323 package. This component is rated for 40 V DC reverse voltage and 250 mA average rectified current per diode, with automotive-grade qualification (AEC-Q101). The part is active in production with 1085 pieces currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to design flexibility, supply chain considerations, or circuit configuration requirements. The BAT64 series provides multiple configuration options within identical electrical ratings and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the BAT64 series is determined by the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): 250 mA
• Voltage - Forward (Vf) (Max) @ If: 750 mV @ 100 mA
• Reverse Recovery Time (trr): 3 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 40 V
• Operating Temperature - Junction: -65°C to 150°C
• Technology: Schottky

Mechanical Equivalence Criteria:

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• Supplier Device Package: SOT-323

Compliance Criteria:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary distinction among BAT64 variants is the diode configuration (Common Anode vs. Common Cathode vs. Single Diode), which determines pin assignment and circuit topology compatibility. All variants maintain identical electrical performance specifications and package form factors.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BAT64AW-7-F, BAT64CW-7-F, and BAT64W-7-F—are active production components with automotive-grade qualification (AEC-Q101) and ROHS3 compliance. Selection between these parts is determined by circuit topology requirements and pin configuration compatibility.

BAT64AW-7-F (Common Anode Configuration): Select this part when the circuit design requires a common anode topology, where both diode cathodes are independently accessible and the anode is shared.

BAT64CW-7-F (Common Cathode Configuration): Select this part when the circuit design requires a common cathode topology, where both diode anodes are independently accessible and the cathode is shared.

BAT64W-7-F (Single Diode Configuration): Select this part when the circuit design requires a single diode element without array configuration, or when only one diode function is needed in the circuit.

All parts maintain identical electrical performance specifications, reverse recovery characteristics, and thermal operating ranges. Substitution is valid only when the circuit topology accommodates the specific pin configuration of the selected variant. The BAT64W-7-F offers the highest current inventory availability at 4100 pieces.

Frequently Asked Questions (FAQ)

Q: Can BAT64CW-7-F replace BAT64AW-7-F in any circuit?

A: Substitution is valid only if the circuit topology accommodates the Common Cathode configuration. The electrical performance is identical, but the pin assignment differs. Common Anode and Common Cathode configurations have different internal connections and cannot be interchanged without circuit redesign.

Q: What is the primary difference between BAT64AW-7-F and BAT64W-7-F?

A: BAT64AW-7-F is a diode array with two diodes in a Common Anode configuration. BAT64W-7-F is a single diode element. Both occupy the same SC-70, SOT-323 package and deliver identical electrical performance per diode. Selection depends on whether the circuit requires a dual-diode array or a single diode function.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry automotive-grade qualification (AEC-Q101) and are compliant with ROHS3 and REACH requirements, making them suitable for automotive circuit designs.

Q: Do these parts have identical thermal characteristics?

A: Yes. All three parts operate across the same junction temperature range of -65°C to 150°C and maintain identical reverse recovery time (3 ns) and leakage current specifications (2 µA @ 40 V).

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Can I use BAT64W-7-F as a substitute if only one diode is needed from the BAT64AW-7-F array?

A: Substitution is valid from an electrical standpoint, as the BAT64W-7-F delivers identical performance per diode. However, the circuit board layout and PCB footprint must accommodate the different pin configuration of the single diode package.
