S3A V7G Equivalent & Substitute Parts

Part Overview

The S3A V7G 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 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S3A V7G is determined by the following critical parameters:

• Voltage Rating: 50 V DC reverse voltage (Vr) maximum
• Current Rating: 3 A average rectified current (Io)
• Package Type: DO-214AB / SMC surface mount configuration
• Technology: Standard recovery rectifier diode
• Compliance: ROHS3 and REACH requirements

The S3A manufactured by Diodes Incorporated meets all substitution criteria. Both parts share identical voltage and current ratings, equivalent package specifications, and matching compliance certifications. Differences in reverse recovery time (1.5 µs vs. 2 µs) and junction temperature range (-55°C to 150°C vs. -65°C to 150°C) remain within acceptable tolerance for standard rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

The S3A manufactured by Diodes Incorporated is a direct functional equivalent to the S3A V7G. Both components satisfy identical electrical specifications for voltage and current ratings, operate within compatible temperature ranges, and maintain equivalent compliance certifications under ROHS3 and REACH standards.

The S3A V7G is listed as discontinued at DiGi Electronics, while the Diodes Incorporated S3A is classified as obsolete. Both product statuses indicate limited availability through standard distribution channels. Selection between these parts should be based on current inventory access and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the S3A from Diodes Incorporated directly replace the S3A V7G from Taiwan Semiconductor Corporation?

A: Yes. Both parts share identical voltage (50 V) and current (3 A) ratings, operate in the same DO-214AB surface mount package, and meet ROHS3 compliance requirements. Electrical performance differences are within standard rectifier diode tolerances.

Q: What is the significance of the different reverse recovery times (1.5 µs vs. 2 µs)?

A: The reverse recovery time difference of 0.5 µs represents a minor variation in switching characteristics. For standard rectifier applications operating at conventional frequencies, this difference does not affect functional compatibility.

Q: Are there package compatibility concerns between these parts?

A: No. Both the S3A V7G and S3A are specified for DO-214AB / SMC surface mount packages with identical footprints and mounting requirements.

Q: What is the impact of the different junction temperature ranges?

A: The S3A from Diodes Incorporated supports a lower minimum junction temperature (-65°C vs. -55°C), providing extended low-temperature operation capability. The maximum temperature rating of 150°C is identical for both parts.

Q: How do the capacitance specifications differ?

A: The S3A V7G specifies 60 pF at 4 V, 1 MHz, while the Diodes Incorporated S3A specifies 40 pF at the same conditions. This 20 pF difference may affect high-frequency circuit behavior in sensitive applications but does not prevent substitution in standard rectifier configurations.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the S3A V7G and S3A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.
