BAT64SW-7-F Equivalent & Substitute Parts

Part Overview

The BAT64SW-7-F is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Series Connection in a surface mount SC-70, SOT-323 package. This component is designed for applications requiring fast recovery rectification at 40 V and 250 mA per diode. The part is Active status and carries automotive-grade qualification (AEC-Q101), making it suitable for demanding automotive and industrial applications. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or application-specific configuration needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT64SW-7-F are qualified based on the following criteria:

Electrical Parameters (Must Match):

• 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 ~ 150°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

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

Configuration Variation (Allowed): The primary difference among qualified substitutes is the internal diode configuration: Series Connection (BAT64SW-7-F) versus Common Cathode (BAT64CW-7-F) versus single diode (BAT64W-7-F). These configurations determine pin connectivity and circuit topology but maintain identical electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BAT64SW-7-F, BAT64CW-7-F, and BAT64W-7-F—are Active status components manufactured by Diodes Incorporated with identical electrical specifications and automotive-grade AEC-Q101 qualification. Selection between these parts is determined by circuit topology requirements:

BAT64SW-7-F (Series Connection): Use when the application requires two diodes in series configuration with independent anode and cathode connections.

BAT64CW-7-F (Common Cathode): Use when the application requires two diodes sharing a common cathode node, enabling parallel anode connections.

BAT64W-7-F (Single Diode): Use when the application requires a single diode element without array configuration.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity (MSL 1), and identical thermal and electrical performance across the -65°C to 150°C junction temperature range. Selection should be based on circuit schematic requirements and PCB layout constraints rather than electrical performance, as all three deliver equivalent rectification characteristics at 40 V, 250 mA, and 3 ns reverse recovery time.

Frequently Asked Questions (FAQ)

Q: Can BAT64CW-7-F replace BAT64SW-7-F in any circuit?

A: No. BAT64CW-7-F has a Common Cathode configuration while BAT64SW-7-F has a Series Connection configuration. These differ in internal pin connectivity. Substitution is only valid if the circuit topology matches the configuration type. Verify schematic requirements before substitution.

Q: What is the difference between BAT64W-7-F and BAT64SW-7-F?

A: BAT64W-7-F is a single diode element, while BAT64SW-7-F is a diode array with two diodes in series connection. Both share identical electrical specifications (40 V, 250 mA, 3 ns trr) and package (SOT-323), but differ in internal configuration and pin count.

Q: Are all three parts automotive qualified?

A: Yes. BAT64SW-7-F, BAT64CW-7-F, and BAT64W-7-F all carry AEC-Q101 automotive qualification and Automotive grade designation, making them suitable for automotive and industrial applications.

Q: Do these parts have the same package footprint?

A: Yes. All three parts use SC-70, SOT-323 surface mount package with identical physical dimensions and PCB footprint. They are mechanically interchangeable from a board layout perspective, but circuit connectivity differs based on internal configuration.

Q: What is the reverse recovery time specification?

A: All three parts specify 3 ns reverse recovery time (trr), indicating fast recovery Schottky diode performance suitable for high-frequency switching applications.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with unlimited moisture sensitivity (MSL 1), meeting environmental and reliability standards for commercial and automotive applications.

Q: What is the maximum reverse voltage rating?

A: All three parts are rated for 40 V maximum DC reverse voltage (Vr). Operating above this voltage will result in component failure.

Q: Can these parts handle 250 mA continuously?

A: Yes. All three parts are rated for 250 mA average rectified current (Io) per diode. For BAT64SW-7-F and BAT64CW-7-F, this rating applies to each diode element within the array.
