BAT64W-7-F Equivalent & Substitute Parts

Part Overview

The BAT64W-7-F is a Schottky diode manufactured by Diodes Incorporated, designed for surface mount applications in automotive-grade circuits. This single diode component operates at 40 V reverse voltage with 250 mA average rectified current and features fast recovery characteristics with a 3 ns reverse recovery time. The part is actively produced and maintains full automotive qualification under AEC-Q101 standards. Substitute parts are identified to provide design flexibility when the primary part number is unavailable or when circuit topology requires alternative diode configurations while maintaining electrical performance within specified parameters.

Substitute Part Grouping Explanation

Substitution of the BAT64W-7-F is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 250 mA per diode
• Voltage - Forward (Vf) (Max) @ If: 750 mV @ 100 mA
• Reverse Recovery Time (trr): 3 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 40 V
• Technology: Schottky

Mechanical & Compliance Equivalence Criteria:

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 150°C
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The BAT64CW-7-F qualifies as a parametric equivalent despite its diode configuration difference (1 Pair Common Cathode array versus single diode). Both parts maintain identical electrical performance per diode element, identical package footprint, and identical automotive qualification status. Circuit topology and pinout requirements determine applicability of the array configuration in specific designs.

Engineering Selection Recommendations

BAT64W-7-F (Primary Part): The BAT64W-7-F is the baseline single-diode configuration. Selection is appropriate for circuits requiring a discrete Schottky diode in a single-element topology. Active product status with 4100 units in stock ensures supply continuity. Full automotive qualification and AEC-Q101 certification support deployment in automotive and industrial applications requiring high reliability standards.

BAT64CW-7-F (Parametric Equivalent): The BAT64CW-7-F provides electrical equivalence through a diode array configuration (1 Pair Common Cathode). Selection is appropriate only when circuit design incorporates the common cathode topology or when dual-diode functionality is required within a single package. Identical electrical performance per diode element, identical package footprint, and identical automotive qualification ensure functional compatibility in applicable topologies. Current inventory of 942 units supports availability.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical operating temperature ranges. Selection between these parts is determined by circuit topology requirements and pinout compatibility, not by electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can BAT64CW-7-F directly replace BAT64W-7-F in any circuit?

A: No. While both parts share identical electrical performance specifications and package footprint, the BAT64CW-7-F is a diode array with common cathode configuration, whereas the BAT64W-7-F is a single diode. Direct replacement is possible only in circuits designed for the common cathode topology. Pinout and circuit topology must be verified before substitution.

Q: Are the electrical performance characteristics identical between BAT64W-7-F and BAT64CW-7-F?

A: Yes. Both parts specify identical voltage ratings (40 V reverse), current ratings (250 mA), forward voltage drop (750 mV @ 100 mA), reverse recovery time (3 ns), and reverse leakage current (2 µA @ 40 V). Performance per diode element is equivalent.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both BAT64W-7-F and BAT64CW-7-F carry Automotive grade classification and AEC-Q101 qualification. Both are suitable for automotive and industrial applications requiring high reliability standards.

Q: What is the package compatibility between these parts?

A: Both parts use identical SC-70 / SOT-323 surface mount package. Physical footprint and land pattern are identical, enabling PCB layout compatibility. Pinout differences due to configuration (single diode versus diode pair) must be evaluated separately.

Q: Are there any compliance or environmental differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Both operate across the same temperature range (-65°C to 150°C junction temperature).

Q: What determines whether BAT64CW-7-F can substitute for BAT64W-7-F?

A: Substitution is determined by circuit topology compatibility. The common cathode configuration of BAT64CW-7-F must align with the circuit design. Electrical performance equivalence is confirmed, but pinout and functional topology must be verified against the specific application schematic.
