S5A V6G General Purpose Rectifier Diode – Equivalent & Substitute Parts

Part Overview

The S5A V6G is a general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This component is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. The part operates across a junction temperature range of -55°C to 150°C and complies with RoHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S5A V6G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Package / Case: DO-214AB, SMC (surface mount)
• Mounting Type: Surface Mount
• RoHS3 Compliance

Allowable Variation Criteria:

• Current - Average Rectified (Io): Substitute parts rated at or above 5 A are acceptable
• Reverse Recovery Time (trr): Substitute parts with equal or faster recovery characteristics are acceptable
• Operating Temperature Range: Substitute parts with equal or wider temperature ranges are acceptable

Two substitute parts meet these criteria:

1. S5A (Diotec Semiconductor) – Direct equivalent with identical voltage and package specifications; rated for 8 A (exceeds 5 A requirement); standard recovery speed; active product status
2. RS3AHE3_A/I (Vishay General Semiconductor - Diodes Division) – Similar voltage and package specifications; rated for 3 A (below 5 A requirement); fast recovery characteristics; automotive-grade with AEC-Q101 qualification; active product status

Engineering Selection Recommendations

Primary Substitute: S5A (Diotec Semiconductor)

The S5A from Diotec Semiconductor is the preferred direct substitute for the S5A V6G. This part maintains identical voltage rating (50 V), package specification (DO-214AB, SMC), and recovery characteristics (1.5 µs). The current rating of 8 A exceeds the original 5 A specification, providing design margin. The part is active in production with high inventory availability (64,163 pcs), ensuring supply continuity. RoHS3 compliance is maintained. The operating temperature range (-50°C to 150°C) is slightly narrower at the lower bound but remains suitable for most applications within the original -55°C to 150°C specification.

Secondary Substitute: RS3AHE3_A/I (Vishay General Semiconductor - Diodes Division)

The RS3AHE3_A/I from Vishay is a similar substitute suitable for applications where current requirements do not exceed 3 A. This part matches the voltage rating (50 V) and package specification (DO-214AB, SMC). The reverse recovery time of 150 ns is significantly faster than the original 1.5 µs, which may provide performance benefits in switching applications. The part carries automotive-grade qualification (AEC-Q101) and is active in production. The operating temperature range (-55°C to 150°C) matches the original specification. This substitute is appropriate only when circuit current demands are 3 A or below.

Compliance and Certification:

Both substitute parts maintain RoHS3 compliance and are suitable for applications requiring regulatory adherence. The Vishay part includes automotive-grade qualification, which may be required for specific end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the S5A from Diotec Semiconductor be used as a direct replacement for the S5A V6G?

A: Yes. Both parts share identical voltage rating (50 V), package specification (DO-214AB, SMC), and recovery characteristics (1.5 µs). The Diotec part is rated for 8 A, which exceeds the original 5 A requirement. The operating temperature range differs slightly at the lower bound (-50°C vs. -55°C), but this does not prevent substitution in most applications.

Q: Why is the RS3AHE3_A/I listed as a substitute if it is rated for only 3 A?

A: The RS3AHE3_A/I is listed as a similar substitute for applications where the circuit current requirement does not exceed 3 A. It meets the voltage and package requirements and offers faster recovery characteristics. Substitution is valid only when circuit design allows operation within the 3 A current limit.

Q: Are both substitute parts available in the same packaging format?

A: Both substitute parts are supplied in DO-214AB (SMC) surface mount packages, identical to the original S5A V6G. The Diotec S5A is supplied in Tape & Reel (TR) format, while the Vishay RS3AHE3_A/I is also supplied in Tape & Reel (TR) format. Both are compatible with automated assembly processes.

Q: What is the difference in recovery speed between the original part and the Vishay substitute?

A: The original S5A V6G has a reverse recovery time of 1.5 µs (standard recovery). The Vishay RS3AHE3_A/I has a reverse recovery time of 150 ns (fast recovery). The Vishay part recovers approximately 10 times faster. This difference may affect switching performance in high-frequency applications.

Q: Do both substitute parts comply with RoHS3 and REACH standards?

A: Yes. The Diotec S5A is RoHS3 compliant. The Vishay RS3AHE3_A/I is RoHS3 compliant and REACH unaffected. Both parts meet regulatory requirements for restricted substance compliance.

Q: What is the inventory status of the substitute parts?

A: The Diotec S5A has 64,163 pcs in stock. The Vishay RS3AHE3_A/I has 891 pcs in stock. Both parts are active products with available inventory for procurement.
