BAT54AD REG Equivalent & Substitute Parts

Part Overview

The BAT54AD REG is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 2 Pair Common Anode device rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. The component is housed in a 6-TSSOP (SC-88, SOT-363) surface mount package and is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or manufacturer availability while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT54AD REG are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Parameters (Must Match):

• 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
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts are grouped into two categories based on diode configuration: Common Anode configuration (BAT54ADW-7-F and BAT54ADW-TP) and Common Cathode configuration (BAT54CDW-7-F). The Common Cathode variant represents a functional alternative for applications where the circuit topology accommodates inverted pin configuration while maintaining all other electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Pin-Compatible Substitutes (Common Anode Configuration):

BAT54ADW-7-F (Diodes Incorporated) and BAT54ADW-TP (Micro Commercial Co) are direct parametric equivalents to the BAT54AD REG with identical Common Anode diode configuration. Both parts maintain all electrical specifications, thermal operating range, and compliance certifications. Selection between these options is determined by packaging format (Tape & Reel) and inventory availability. All three Common Anode variants are suitable for direct PCB layout substitution without circuit modification.

Functional Alternative (Common Cathode Configuration):

BAT54CDW-7-F (Diodes Incorporated) provides identical electrical performance and thermal characteristics but features Common Cathode configuration instead of Common Anode. This part is suitable only for applications where the circuit topology accommodates inverted pin configuration. PCB layout modification is required for this substitution. All compliance and certification parameters remain equivalent.

Compliance and Certification Status:

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and Active product status. No additional qualification or testing is required from a regulatory or environmental standpoint.

Frequently Asked Questions (FAQ)

Q: Can BAT54ADW-7-F be used as a direct replacement for BAT54AD REG without PCB modification?

A: Yes. BAT54ADW-7-F is a parametric equivalent with identical Common Anode configuration, electrical specifications, thermal range, and SOT-363 package. Direct substitution on the PCB is possible without circuit modification.

Q: What is the difference between BAT54ADW-TP and BAT54ADW-7-F?

A: Both parts are parametric equivalents manufactured by different suppliers (Micro Commercial Co and Diodes Incorporated, respectively). The primary difference is packaging format (both Tape & Reel) and inventory availability. Electrical and mechanical specifications are identical.

Q: Can BAT54CDW-7-F replace BAT54AD REG in any application?

A: BAT54CDW-7-F has identical electrical specifications and thermal operating range but features Common Cathode configuration instead of Common Anode. Substitution requires circuit topology compatibility and PCB layout modification. Direct pin-for-pin replacement is not possible.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (BAT54ADW-7-F, BAT54ADW-TP, and BAT54CDW-7-F) maintain ROHS3 compliance status identical to the BAT54AD REG.

Q: What is the moisture sensitivity level for these diode arrays?

A: All parts, including the main BAT54AD REG and all substitutes, have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without special moisture control requirements.

Q: Do the substitute parts have the same reverse recovery time?

A: Yes. All substitute parts maintain a reverse recovery time (trr) of 5 ns, identical to the BAT54AD REG.

Q: Can I use BAT54ADW-TP if BAT54ADW-7-F is unavailable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, thermal characteristics, and SOT-363 package. Selection is based on availability and packaging format preference.
