BAT54CDW-7 Equivalent & Substitute Parts

Part Overview

The BAT54CDW-7 is a Schottky diode array featuring a 2 Pair Common Cathode configuration rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. This component is packaged in a 6-TSSOP (SC-88, SOT-363) surface mount package and is designed for small signal applications with reverse recovery time of 5 ns.

The BAT54CDW-7 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the BAT54CDW-7 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires that alternative parts maintain identical values for the following parameters:

• Diode Configuration: 2 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Operating Temperature - Junction: -65°C ~ 125°C
• Package / Case: 6-TSSOP, SC-88, SOT-363
• Supplier Device Package: SOT-363

Parts meeting these criteria are considered direct parametric equivalents and may be substituted without modification to circuit design or board layout.

Parameter Comparison

Engineering Selection Recommendations

The BAT54CDW-7-F is a direct parametric equivalent to the BAT54CDW-7. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications and mechanical packaging.

The primary distinction between these parts is product status and compliance certification. The BAT54CDW-7 is discontinued at DiGi Electronics, whereas the BAT54CDW-7-F maintains active product status. Additionally, the BAT54CDW-7-F is ROHS3 compliant, whereas the BAT54CDW-7 is RoHS non-compliant.

For new designs and ongoing production requiring compliance with current environmental regulations, the BAT54CDW-7-F is the appropriate selection. The packaging difference (Tape & Reel for BAT54CDW-7-F versus bulk for BAT54CDW-7) reflects standard distribution formats and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BAT54CDW-7-F be used as a direct replacement for the BAT54CDW-7?

A: Yes. The BAT54CDW-7-F is a direct parametric equivalent. All electrical specifications, including reverse voltage rating, forward voltage drop, reverse recovery time, and leakage current, are identical. The package type (6-TSSOP, SC-88, SOT-363) and pin configuration are identical, enabling direct substitution without circuit modification or board layout changes.

Q: What is the difference between the BAT54CDW-7 and BAT54CDW-7-F?

A: The parts are electrically and mechanically identical. The primary differences are product status (BAT54CDW-7 is discontinued; BAT54CDW-7-F is active) and RoHS compliance (BAT54CDW-7-F is ROHS3 compliant; BAT54CDW-7 is non-compliant). The packaging format differs (BAT54CDW-7-F is supplied in Tape & Reel; BAT54CDW-7 is supplied in bulk).

Q: Are there any compatibility concerns when substituting the BAT54CDW-7-F for the BAT54CDW-7?

A: No compatibility concerns exist. Both parts feature the 6-TSSOP (SOT-363) package with identical pin assignments and mechanical dimensions. The diode array configuration (2 Pair Common Cathode) is identical, ensuring functional equivalence in all circuit applications.

Q: What parameters must remain identical for a part to be considered a substitute for the BAT54CDW-7?

A: Substitute parts must maintain identical values for diode configuration, technology type, maximum reverse voltage (30 V), average rectified current (200 mA per diode), forward voltage drop (1 V @ 100 mA), reverse recovery time (5 ns), reverse leakage current (2 µA @ 25 V), operating temperature range (-65°C to 125°C), and package type (6-TSSOP, SC-88, SOT-363).

Q: Is the BAT54CDW-7-F suitable for applications requiring RoHS compliance?

A: Yes. The BAT54CDW-7-F is ROHS3 compliant and is suitable for applications requiring adherence to current environmental regulations. The BAT54CDW-7 is RoHS non-compliant and should not be used in applications with RoHS compliance requirements.
