GS1J Equivalent & Substitute Parts

Part Overview

The GS1J is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 600 V DC reverse voltage with 1 A average rectified current. The device is packaged in the DO-214AC (SMA) surface mount configuration and is classified as Active product status. This diode is suitable for standard recovery applications requiring moderate voltage and current ratings in compact surface mount form factors.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate component availability across different procurement channels and manufacturing sources.

Substitute Part Grouping Explanation

Substitute parts for the GS1J are identified based on electrical and mechanical parameter equivalence within the rectifier diode category. The substitution logic is based on the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 2.5 µs
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V

Mechanical Equivalence Criteria:

• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all electrical, mechanical, and compliance parameters are classified as parametric equivalents and direct substitutes for the GS1J.

Parameter Comparison

Engineering Selection Recommendations

GS1J (SMC Diode Solutions): The GS1J is an Active product with full parametric specification documentation. This part is suitable for applications requiring complete electrical characterization, including reverse recovery time and reverse leakage current specifications. ROHS3 compliance and MSL 1 rating support unrestricted storage and handling. Current inventory of 20,200 pieces supports high-volume production requirements.

S1J (YAGEO): The S1J is an Active product classified as a parametric equivalent based on matching voltage, current, and forward voltage specifications. ROHS3 compliance and MSL 1 rating provide equivalent environmental and regulatory compliance. The S1J is available in Cut Tape (CT) and Digi-Reel® packaging formats. Inventory of 5,851 pieces supports moderate-volume applications. This part is suitable for applications where the specified electrical parameters are the primary selection criteria.

Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the S1J be used as a direct replacement for the GS1J?

A: The S1J meets the critical electrical parameters (600 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage) and mechanical specifications (DO-214AC package, surface mount) required for substitution. Both parts are ROHS3 compliant with MSL 1 rating. The S1J is a parametric equivalent suitable for direct substitution in applications where the specified electrical characteristics are the primary design requirement.

Q: What are the key differences between the GS1J and S1J?

A: The GS1J provides complete parametric documentation including reverse recovery time (2.5 µs) and reverse leakage current (5 µA @ 600 V). The S1J datasheet does not specify these parameters. Both parts meet the same voltage and current ratings and share identical compliance certifications. Selection between these parts depends on whether detailed transient and leakage specifications are required for circuit design validation.

Q: Are the packaging formats interchangeable?

A: Both the GS1J and S1J use the DO-214AC (SMA) package configuration for surface mount assembly. The GS1J is supplied in standard packaging, while the S1J is available in Cut Tape (CT) and Digi-Reel® formats. These packaging formats are compatible with standard surface mount assembly equipment and do not affect electrical performance or board-level compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the GS1J and S1J are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. These certifications confirm equivalent regulatory and compliance status for procurement, storage, and export purposes.

Q: Which part should be selected for high-volume production?

A: The GS1J offers higher current inventory (20,200 pieces) compared to the S1J (5,851 pieces), making it the preferred choice for high-volume production runs. The S1J is suitable for moderate-volume applications or as a secondary source option. Both parts are Active products with established supply channels.
