S4J R6 Equivalent & Substitute Parts

Part Overview

The S4J R6 is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 4 A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for standard recovery applications requiring moderate voltage and current handling in compact form factors.

The S4J R6 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain flexibility for applications requiring this diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S4J R6 is determined by matching the following critical electrical and mechanical parameters:

• Voltage Rating: DC reverse voltage of 600 V maximum
• Current Rating: Average rectified current of 4 A
• Forward Voltage Drop: 1.15 V maximum at 4 A forward current
• Recovery Characteristics: Standard recovery with reverse recovery time of 1.5 µs
• Reverse Leakage: 10 µA maximum at 600 V
• Package: DO-214AB (SMC) surface mount configuration
• Compliance: ROHS3 compliant, REACH unaffected

The S4J V7G meets all specified electrical parameters and mechanical requirements, qualifying it as a parametric equivalent for the S4J R6.

Parameter Comparison

Engineering Selection Recommendations

The S4J V7G serves as a direct parametric equivalent to the S4J R6. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, thermal ratings, and compliance certifications.

Selection between these parts should be based on:

• Availability: The S4J V7G currently maintains higher inventory levels (1708 pieces) compared to the S4J R6 (980 pieces)
• Packaging Format: The S4J R6 is supplied in standard packaging, while the S4J V7G is available in Cut Tape (CT) format, which may influence procurement and assembly workflows
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for applications requiring environmental compliance

No electrical performance differences exist between these components. The choice between them depends on supply chain requirements and packaging preferences for manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can the S4J V7G be used as a direct replacement for the S4J R6?

A: Yes. The S4J V7G is a parametric equivalent with identical voltage rating (600 V), current rating (4 A), forward voltage drop (1.15 V @ 4 A), reverse recovery time (1.5 µs), and package configuration (DO-214AB SMC). All electrical and thermal specifications match exactly.

Q: Are there any differences in the DO-214AB package between these parts?

A: No. Both the S4J R6 and S4J V7G use the DO-214AB (SMC) surface mount package with identical mechanical and electrical interface specifications.

Q: What is the difference between the standard packaging and Cut Tape (CT) format?

A: The packaging format affects delivery and handling. Standard packaging and Cut Tape (CT) represent different supply configurations from the manufacturer. The electrical and mechanical properties of the diode itself remain unchanged.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the S4J R6 and S4J V7G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the operating temperature range for these diodes?

A: Both parts operate across a junction temperature range of -55°C to 150°C, suitable for industrial and commercial applications.

Q: Can these diodes be used in high-frequency switching applications?

A: These are standard recovery diodes with a reverse recovery time of 1.5 µs. They are designed for general-purpose rectification applications. High-frequency switching applications typically require fast recovery or ultrafast recovery diodes with shorter reverse recovery times.
