S4A V6G Equivalent & Substitute Parts

Part Overview

The S4A V6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 4 A average rectified current in a surface mount DO-214AB (SMC) package. This part is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The S4A V6G operates across a junction temperature range of -55°C to 150°C and exhibits standard recovery characteristics with a reverse recovery time of 1.5 µs. The device is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S4A V6G is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Current Rating Consideration: The S4A V6G is rated for 4 A average rectified current. Substitute parts must meet or exceed this current specification to ensure equivalent or superior performance in the application circuit.

Recovery Characteristics: The S4A V6G exhibits standard recovery characteristics (>500 ns) with a reverse recovery time of 1.5 µs. Substitute parts with faster recovery times (≤500 ns) are acceptable as they represent improved performance without circuit incompatibility.

Temperature Range: The S4A V6G operates from -55°C to 150°C junction temperature. Substitute parts with equal or extended temperature ranges maintain thermal compatibility.

Engineering Selection Recommendations

S4A (Direct Substitute)

The S4A from Taiwan Semiconductor Corporation is the direct equivalent to the S4A V6G. This part maintains identical electrical specifications including 50 V reverse voltage, 4 A average rectified current, 1.5 µs reverse recovery time, and operating temperature range of -55°C to 150°C. The S4A is currently active in production and available in Tape & Reel (TR) packaging. RoHS3 compliance and MSL 1 rating are maintained. This substitute provides seamless replacement with no circuit redesign required.

UFS305JE3/TR13 (Similar Substitute)

The UFS305JE3/TR13 from Microchip Technology is a similar substitute suitable for applications where current rating reduction is acceptable. This part shares the 50 V reverse voltage rating and DO-214AB package with the S4A V6G. The primary differences are reduced average rectified current (3 A versus 4 A) and significantly faster recovery characteristics (30 ns versus 1.5 µs). The UFS305JE3/TR13 operates across an extended temperature range (-55°C to 175°C) and is currently active in production. RoHS3 compliance and MSL 1 rating are maintained. This substitute is applicable only in circuits where the 3 A current rating meets design requirements.

Frequently Asked Questions (FAQ)

Q: Can the S4A be used as a direct replacement for the S4A V6G?

A: Yes. The S4A is the direct equivalent with identical electrical specifications, package type (DO-214AB, SMC), and operating parameters. The S4A is currently active in production, whereas the S4A V6G is discontinued.

Q: What are the limitations of using UFS305JE3/TR13 as a substitute?

A: The UFS305JE3/TR13 is rated for 3 A average rectified current, compared to the 4 A rating of the S4A V6G. This substitute is applicable only in circuits where the maximum current requirement does not exceed 3 A. All other electrical parameters, including voltage rating and package type, are compatible.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the S4A and UFS305JE3/TR13 are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of the S4A V6G.

Q: Does the faster recovery time of UFS305JE3/TR13 affect circuit compatibility?

A: The UFS305JE3/TR13 exhibits fast recovery characteristics (30 ns) compared to the standard recovery of the S4A V6G (1.5 µs). Faster recovery time represents improved performance and does not introduce circuit incompatibility. The part remains suitable for standard rectification applications.

Q: What is the packaging difference between the S4A and S4A V6G?

A: The S4A V6G is supplied in standard packaging, while the S4A is supplied in Tape & Reel (TR) format. Both use the identical DO-214AB (SMC) package type and are mechanically and electrically interchangeable.

Q: Can the S4A V6G be used in applications requiring operation above 150°C?

A: No. The S4A V6G is rated for junction temperatures up to 150°C. For applications requiring extended temperature operation, the UFS305JE3/TR13 (rated to 175°C) is suitable, provided the 3 A current rating meets circuit requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts (S4A V6G, S4A, and UFS305JE3/TR13) share identical RoHS3 compliance, REACH unaffected status, and ECCN EAR99 classification. No regulatory differences exist between these components.
