BAT54CW RVG Equivalent & Substitute Parts

Part Overview

The BAT54CW RVG is a Schottky diode array in a 1 Pair Common Cathode configuration, rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. Manufactured by Taiwan Semiconductor Corporation, this surface mount component is housed in an SC-70, SOT-323 package and is currently Active in product status with ROHS3 compliance.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple manufacturers is needed to ensure supply chain continuity. The BAT54 series offers multiple configuration options (Common Cathode and Common Anode) and manufacturer variants that maintain electrical equivalence while providing flexibility in procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54CW RVG is determined by the following critical parameters:

Electrical Equivalence Requirements:

• 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
• Technology: Schottky

Package and Mounting Requirements:

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

Configuration Consideration: The BAT54CW RVG features a 1 Pair Common Cathode configuration. Substitute parts with Common Anode configuration (BAT54AW series) are electrically equivalent in terms of voltage and current ratings but differ in pin arrangement. Selection between Common Cathode and Common Anode variants depends on circuit topology requirements.

Compliance and Status:

• RoHS3 Compliance is maintained across all active substitute parts
• Product Status (Active vs. Discontinued) affects long-term availability
• Automotive-grade variants (AEC-Q101 qualified) are available for applications requiring automotive qualification

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Substitution (Common Cathode Configuration):

BAT54CW-7-F (Diodes Incorporated) is the primary substitute for BAT54CW RVG. Both parts maintain identical electrical specifications, Common Cathode configuration, and ROHS3 compliance. BAT54CW-7-F is currently Active with high inventory availability (118,760 units), ensuring supply continuity.

BAT54CWT-TP (Micro Commercial Co) provides an alternative Common Cathode option with equivalent electrical performance and ROHS3 compliance. This part is Active with 3,390 units in stock.

For Automotive Applications:

BAT54CWQ-7-F (Diodes Incorporated) is a Common Cathode variant qualified to AEC-Q101 automotive standards. This part maintains all electrical equivalence parameters and ROHS3 compliance, suitable for automotive-grade circuit requirements.

For Common Anode Configuration Requirements:

When circuit topology requires Common Anode configuration, BAT54AW-7-F (Diodes Incorporated) provides electrical equivalence with Active product status and ROHS3 compliance. BAT54AWQ-7-F and BAT54AWQ-13-F offer automotive-grade (AEC-Q101) Common Anode alternatives.

BAT54AW-7 (Diodes Incorporated) is Discontinued at DiGi Electronics and does not meet ROHS3 compliance; this part should not be selected for new designs.

Packaging Considerations:

All substitute parts are housed in SC-70, SOT-323 surface mount packages with identical pin configurations within their respective diode configurations (Common Cathode or Common Anode). Packaging format variations (Cut Tape, Tape & Reel) do not affect electrical performance and are determined by procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can BAT54AW series (Common Anode) parts directly replace BAT54CW series (Common Cathode) parts?

A: No. While BAT54AW and BAT54CW series maintain identical electrical specifications (30 V, 200 mA, 1 V forward voltage, 5 ns recovery time), they differ in diode configuration and pin arrangement. Common Anode and Common Cathode configurations have different pin assignments and cannot be used interchangeably without circuit redesign. Selection depends on the specific circuit topology.

Q: What is the difference between BAT54CW-7-F and BAT54CWT-TP?

A: Both parts are Common Cathode Schottky diode arrays with identical electrical specifications. The primary differences are manufacturer (Diodes Incorporated vs. Micro Commercial Co) and packaging format (Cut Tape & Digi-Reel vs. Tape & Reel). Electrical performance and package type (SC-70, SOT-323) are equivalent.

Q: Are automotive-grade variants (AEC-Q101) electrically equivalent to standard variants?

A: Yes. BAT54CWQ-7-F and BAT54AWQ-7-F/BAT54AWQ-13-F maintain identical electrical specifications to their non-automotive counterparts. The AEC-Q101 qualification indicates additional testing and quality assurance for automotive applications but does not alter electrical performance.

Q: Why is BAT54AW-7 listed as a substitute if it is Discontinued?

A: BAT54AW-7 is included in the substitute list for reference purposes only. This part is Discontinued at DiGi Electronics and does not meet ROHS3 compliance. It should not be selected for new designs or long-term applications.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the component meets European environmental standards restricting hazardous materials. All active substitute parts listed maintain ROHS3 compliance, ensuring regulatory compliance for applications subject to these requirements.

Q: Can I use BAT54CW-7-F as a direct replacement for BAT54CW RVG in existing designs?

A: Yes. BAT54CW-7-F is electrically and mechanically equivalent to BAT54CW RVG. Both are Common Cathode Schottky diode arrays with 30 V rating, 200 mA current, identical forward voltage characteristics, and SC-70, SOT-323 packaging. No circuit modifications are required.

Q: What is the significance of the reverse recovery time (trr) specification?

A: Reverse recovery time (5 ns for all listed parts) indicates the speed at which the diode transitions from forward conduction to reverse blocking. This parameter is critical for high-frequency switching applications. All substitute parts maintain identical 5 ns recovery time, ensuring equivalent performance in switching circuits.

Q: How do I determine which substitute part to select?

A: Selection depends on three primary factors: (1) Required diode configuration (Common Cathode or Common Anode) based on circuit topology, (2) Compliance requirements (ROHS3 for standard applications, AEC-Q101 for automotive), and (3) Packaging format preference (Cut Tape, Tape & Reel, or Digi-Reel). All listed parts maintain electrical equivalence within their respective configurations.
