BAT54CD REG Equivalent & Substitute Parts

Part Overview

The BAT54CD REG is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 2 Pair Common Cathode 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 full RoHS3 compliance.

Substitute parts are identified to address component availability, supply chain requirements, or specific packaging preferences while maintaining electrical and mechanical compatibility within the BAT54 base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the BAT54CD REG is based on the following criteria:

Primary Substitution Criteria (Identical Configuration):

• Diode Configuration: 2 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Package / Case: 6-TSSOP, SC-88, SOT-363
• Mounting Type: Surface Mount

Secondary Substitution Criteria (Functional Equivalence):

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

Configuration Note: BAT54ADW-7-F and BAT54ADW-TP are classified as 2 Pair Common Anode devices and represent functional alternatives within the BAT54 base product family. These parts share identical electrical performance parameters and package specifications but differ in internal diode configuration. BAT54CDW-7-F maintains identical Common Cathode configuration as the main part.

Parameter Comparison

Engineering Selection Recommendations

BAT54CDW-7-F (Diodes Incorporated): This substitute maintains identical Common Cathode configuration as the BAT54CD REG main part. All electrical parameters, thermal specifications, and compliance certifications are equivalent. This part is suitable for direct replacement in applications requiring Common Cathode diode array topology. Product status is Active with full RoHS3 compliance and REACH Unaffected designation.

BAT54ADW-7-F (Diodes Incorporated) and BAT54ADW-TP (Micro Commercial Co): These substitutes feature Common Anode configuration instead of Common Cathode. While all electrical performance parameters remain identical (30 V reverse voltage, 200 mA current rating, 1 V forward voltage, 5 ns recovery time), the internal diode configuration differs. These parts are suitable only for applications designed for Common Anode topology. Both maintain Active product status, RoHS3 compliance, and REACH Unaffected designation. BAT54ADW-TP offers significantly higher inventory availability (362,100 pieces) compared to other options.

Compliance and Regulatory Status: All substitute parts maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) classification as the main part. ECCN and HTSUS classifications are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can BAT54ADW-7-F or BAT54ADW-TP be used as direct replacements for BAT54CD REG?

A: BAT54ADW-7-F and BAT54ADW-TP are functionally equivalent in terms of electrical performance and package specifications but feature Common Anode configuration instead of Common Cathode. Direct substitution is possible only if the circuit design accommodates Common Anode topology. Circuit board layout and connection points must be verified for compatibility.

Q: What is the difference between Common Cathode and Common Anode configurations?

A: Common Cathode configuration connects the cathode terminals of both diode pairs to a single common node. Common Anode configuration connects the anode terminals of both diode pairs to a single common node. The choice between these configurations depends on circuit topology and biasing requirements.

Q: Is BAT54CDW-7-F a pin-for-pin replacement for BAT54CD REG?

A: BAT54CDW-7-F maintains identical Common Cathode configuration and 6-TSSOP (SOT-363) package as BAT54CD REG. Both parts share the same electrical specifications and thermal operating range. Pinout compatibility is maintained within the BAT54 base product family for Common Cathode variants.

Q: Are all substitute parts available in Tape & Reel packaging?

A: BAT54ADW-7-F, BAT54ADW-TP, and BAT54CDW-7-F are all supplied in Tape & Reel (TR) packaging. The main part BAT54CD REG does not specify packaging format in the provided data.

Q: Do all parts meet the same compliance and regulatory requirements?

A: All parts listed maintain RoHS3 compliance, REACH Unaffected status, Moisture Sensitivity Level 1 (Unlimited), and identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications. Regulatory and environmental compliance is consistent across all options.

Q: Which substitute offers the best inventory availability?

A: BAT54ADW-TP (Micro Commercial Co) offers the highest inventory availability at 362,100 pieces. BAT54CDW-7-F (Diodes Incorporated) provides 2,048 pieces, and BAT54ADW-7-F (Diodes Incorporated) provides 1,202 pieces.

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

A: All parts, including the main BAT54CD REG and all substitutes, operate across a junction temperature range of -65°C to 125°C.
