GS1D Equivalent & Substitute Parts Reference

Part Overview

The GS1D is a general-purpose rectifier diode manufactured by SMC Diode Solutions, rated for 200 V DC reverse voltage and 1 A average rectified current in a surface mount SMA (DO-214AC) package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary GS1D component experiences supply constraints, extended lead times, or inventory depletion. Alternative qualified diodes with equivalent electrical and mechanical specifications enable design continuity and procurement flexibility while maintaining circuit performance within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GS1D are qualified based on strict electrical and mechanical parameter alignment within the following criteria:

Primary Substitution Parameters:

• Voltage - DC Reverse (Vr) rating of 200 V or higher
• Current - Average Rectified (Io) rating of 1 A or higher
• Package / Case format: DO-214AC or SMA equivalent
• Mounting Type: Surface Mount
• Forward voltage (Vf) compatibility within acceptable circuit operating margins
• Reverse leakage current (Ir) at rated voltage
• RoHS3 compliance and MSL 1 rating for manufacturing compatibility

Parametric Equivalent Classification: The S1D (YAGEO) meets all core electrical and mechanical requirements with identical voltage and current ratings, matching package specification, and equivalent compliance certifications.

Similar Classification: The ES1D R3G (Taiwan Semiconductor Corporation) provides functional equivalence with matching voltage and current ratings in the same package format. This part is noted as discontinued at DiGi Electronics and exhibits different recovery time characteristics (35 ns versus 2.5 µs standard recovery), representing a faster recovery technology variant within the same electrical class.

Engineering Selection Recommendations

Primary Selection: S1D (YAGEO)

The S1D represents the preferred parametric equivalent for GS1D replacement. Both components share identical voltage and current ratings (200 V, 1 A), matching forward voltage specification (1.1 V @ 1 A), equivalent package format (DO-214AC/SMA), and full RoHS3 compliance with MSL 1 rating. The S1D maintains Active product status with 5993 units in stock, ensuring supply continuity. This part is suitable for direct substitution in applications where standard recovery time characteristics are required.

Secondary Selection: ES1D R3G (Taiwan Semiconductor Corporation)

The ES1D R3G provides functional equivalence with matching 200 V reverse voltage and 1 A current ratings in the identical DO-214AC/SMA package. This component exhibits superior forward voltage performance (950 mV @ 1 A versus 1.1 V) and significantly faster reverse recovery time (35 ns versus 2.5 µs), classifying it as a fast recovery variant. The ES1D R3G is noted as discontinued at DiGi Electronics with limited inventory (840 units). This part is suitable for applications requiring fast recovery characteristics, provided the operating temperature range (-55 to 150 °C) satisfies circuit requirements. The narrower temperature range compared to GS1D (-65 to 175 °C) must be evaluated against specific application thermal specifications.

Compliance Considerations:

All three components maintain RoHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and assembly processes. The GS1D and S1D both carry REACH Affected status, while ES1D R3G is REACH Unaffected. Selection should account for supply chain compliance requirements specific to end-use applications.

Frequently Asked Questions (FAQ)

Q: Can the S1D be used as a direct replacement for GS1D in all applications?

A: The S1D meets all specified electrical parameters (200 V reverse voltage, 1 A current, 1.1 V forward voltage) and package requirements (DO-214AC/SMA surface mount). Direct substitution is supported for applications where standard recovery time operation is acceptable. Verify that component-level testing or qualification procedures do not impose additional manufacturer-specific requirements beyond the provided electrical specifications.

Q: What is the primary difference between GS1D and ES1D R3G?

A: Both components share identical voltage and current ratings with matching package format. The ES1D R3G is classified as a fast recovery diode with 35 ns reverse recovery time compared to the GS1D standard recovery specification of 2.5 µs. The ES1D R3G also exhibits lower forward voltage (950 mV versus 1.1 V @ 1 A). The operating temperature range differs: GS1D operates from -65 to 175 °C while ES1D R3G operates from -55 to 150 °C. Selection between these variants depends on circuit requirements for recovery speed and thermal operating range.

Q: Why is ES1D R3G listed as discontinued?

A: The ES1D R3G is marked as discontinued at DiGi Electronics, indicating this supplier no longer actively stocks or supports this component. While 840 units remain in current inventory, future availability cannot be assured. For new designs or long-term production requirements, the S1D or GS1D are recommended as they maintain Active product status.

Q: Are all three diodes compatible with the same PCB footprint?

A: All three components use the DO-214AC/SMA package format with surface mount configuration. PCB footprints designed for DO-214AC are compatible with GS1D, S1D, and ES1D R3G without modification. Verify that assembly equipment and reflow profiles are qualified for the specific component manufacturer's thermal specifications.

Q: What packaging formats are available for these substitute parts?

A: The GS1D is supplied in Tape & Reel (TR) format. The S1D and ES1D R3G are supplied in Cut Tape (CT) and Digi-Reel® formats. Procurement specifications should account for packaging format requirements to ensure compatibility with automated assembly processes and inventory management systems.

Q: Do all three components meet RoHS3 compliance?

A: Yes, GS1D, S1D, and ES1D R3G all carry RoHS3 Compliant status. All three components maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions without special handling requirements.

Q: How do reverse leakage current specifications compare?

A: Both GS1D and ES1D R3G specify 5 µA reverse leakage current at 200 V. The S1D reverse leakage specification is not provided in available documentation. For applications with strict leakage current requirements, GS1D or ES1D R3G are recommended based on the provided specification data.
