Substitute Part Grouping Explanation

Substitute parts for the BAT64-7-F are identified within the BAT64 base product family from Diodes Incorporated. Substitution is valid when the following parameters match or exceed the main part specifications:

• Voltage - DC Reverse (Vr) (Max): 40 V minimum
• Current - Average Rectified (Io): 250 mA minimum per diode
• Voltage - Forward (Vf) (Max) @ If: 750 mV @ 100 mA maximum
• Reverse Recovery Time (trr): 3 ns maximum
• Current - Reverse Leakage @ Vr: 2 µA @ 40 V maximum
• Package / Case: TO-236-3, SC-59, SOT-23-3 (identical)
• Operating Temperature - Junction: -65°C ~ 150°C minimum range
• Grade: Automotive
• Qualification: AEC-Q101

The BAT64C-7-F and BAT64S-7-F are diode arrays with internal configurations (common cathode and series connection, respectively) that maintain electrical equivalence on a per-diode basis while offering alternative internal topologies for specific circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BAT64-7-F, BAT64C-7-F, and BAT64S-7-F—maintain Active product status and carry identical automotive-grade qualification (AEC-Q101) with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit topology requirements:

BAT64-7-F is a single diode suitable for applications requiring one discrete rectification element per package.

BAT64C-7-F is a diode array with 1 pair common cathode configuration, applicable in circuits where two diodes share a common cathode node.

BAT64S-7-F is a diode array with 1 pair series connection configuration, applicable in circuits where two diodes are internally connected in series.

All three parts are electrically equivalent on a per-diode basis and share identical electrical parameters, thermal operating range, and regulatory compliance. Selection is determined by circuit schematic requirements and PCB layout constraints within the SOT-23-3 package footprint.

Frequently Asked Questions (FAQ)

Q: Can BAT64C-7-F replace BAT64-7-F in any circuit?

A: BAT64C-7-F is electrically equivalent on a per-diode basis but contains two diodes with a common cathode connection. Substitution is valid only if the circuit topology accommodates the common cathode configuration. Single-diode applications require BAT64-7-F or use only one diode element of BAT64C-7-F with the unused element left unconnected.

Q: What is the difference between BAT64C-7-F and BAT64S-7-F?

A: BAT64C-7-F contains two diodes with a common cathode connection (cathodes tied together). BAT64S-7-F contains two diodes in series connection (anode of first diode connected to cathode of second diode). Both maintain identical per-diode electrical specifications but differ in internal topology.

Q: Are all three parts qualified for automotive applications?

A: Yes. BAT64-7-F, BAT64C-7-F, and BAT64S-7-F all carry automotive-grade classification and AEC-Q101 qualification, suitable for automotive circuit applications.

Q: Do these parts share the same package footprint?

A: Yes. All three parts use the TO-236-3, SC-59, SOT-23-3 package with identical surface mount footprint, enabling direct PCB layout compatibility when circuit topology permits.

Q: What is the operating temperature range for all three parts?

A: The junction operating temperature range is -65°C to 150°C for BAT64-7-F, BAT64C-7-F, and BAT64S-7-F.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: What is the reverse recovery time specification?

A: The reverse recovery time (trr) is 3 nanoseconds for all three parts, supporting fast switching applications.
