S3A V6G Equivalent & Substitute Parts

Part Overview

The S3A V6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 3 A average rectified current in a DO-214AB (SMC) surface mount package. This component is classified as discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Substitute parts must maintain electrical performance within the specified voltage and current ratings while accommodating standard recovery characteristics and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3A V6G is determined by strict equivalence across the following parameters:

Primary Electrical Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 3 A
• Speed Classification: Standard Recovery >500ns, > 200mA (Io)

Mechanical Criteria:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8541.10.0080

Substitute parts must satisfy all primary electrical criteria and mechanical requirements. Secondary parameters including reverse recovery time, forward voltage, reverse leakage current, and capacitance may vary within acceptable ranges for general-purpose rectification applications, provided the part maintains the specified voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

S3A (Diodes Incorporated): This part meets all primary electrical and mechanical substitution criteria with identical voltage and current ratings. The part is classified as obsolete, indicating limited future availability. Operating temperature range extends to -65°C, providing broader low-temperature performance than the original S3A V6G. Reverse recovery time is 2 µs compared to 1.5 µs for the original part, remaining within standard recovery classification. This substitute is suitable for applications where component availability from secondary sources is acceptable.

ACGRC301-HF (Comchip Technology): This part satisfies all primary electrical and mechanical substitution criteria with identical 50 V and 3 A ratings. The component maintains active product status, ensuring ongoing availability and supply chain continuity. The part carries automotive-grade qualification (AEC-Q101) and is rated for the same operating temperature range as the original. Reverse leakage current is reduced to 5 µA at 50 V, and junction capacitance is lower at 20 pF, representing improved electrical characteristics. This substitute is recommended for applications requiring long-term component availability and automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the S3A (Diodes Incorporated) be used as a direct replacement for the S3A V6G?

A: Yes. Both parts share identical voltage (50 V), current (3 A), and package specifications (DO-214AB, SMC). Both are ROHS3 compliant. The S3A from Diodes Incorporated is classified as obsolete, which may affect long-term procurement availability.

Q: What is the primary advantage of the ACGRC301-HF over the other substitutes?

A: The ACGRC301-HF maintains active product status, ensuring ongoing availability. It carries automotive-grade qualification (AEC-Q101) and demonstrates improved electrical characteristics including lower reverse leakage current (5 µA versus 10 µA) and reduced junction capacitance (20 pF versus 60 pF).

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts are packaged in DO-214AB (SMC) surface mount format, enabling direct PCB footprint compatibility with the original S3A V6G.

Q: Does the difference in reverse recovery time between substitutes affect circuit performance?

A: The S3A V6G specifies 1.5 µs reverse recovery time, while the S3A (Diodes Incorporated) specifies 2 µs. Both remain within the standard recovery classification (>500ns, >200mA). Selection depends on specific circuit switching requirements; applications with stringent reverse recovery specifications should evaluate the ACGRC301-HF, for which this parameter is not specified in the provided data.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the original S3A V6G.

Q: Which substitute is recommended for new designs?

A: The ACGRC301-HF is recommended for new designs due to active product status, automotive-grade qualification, and improved electrical characteristics. The S3A from Diodes Incorporated is suitable for legacy design support where component availability from secondary sources is acceptable.
