GS1ME-TP Equivalent & Substitute Parts
Part Overview
The GS1ME-TP is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMA) package. This part is manufactured by Micro Commercial Co and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering improved availability and active product support.

Substitute Part Grouping Explanation
Substitute parts for the GS1ME-TP are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:
Critical Parameters for Substitution:
- Voltage - DC Reverse (Vr) (Max): 1000 V minimum
- Current - Average Rectified (Io): 1 A minimum
- Mounting Type: Surface Mount
- Package compatibility: DO-214AC (SMA) or equivalent footprint
Secondary Parameters Affecting Substitution:
- Voltage - Forward (Vf) (Max) @ If: Lower values preferred for efficiency
- Speed characteristics: Standard or faster recovery acceptable
- Current - Reverse Leakage @ Vr: Lower values preferred
- Operating Temperature Range: Extended range acceptable
- Product Status: Active status preferred over obsolete or not for new designs
Substitutes are classified into two categories:
Direct Equivalents: Parts with identical or superior electrical specifications and active product status, maintaining the same package type (DO-214AC/SMA).
Compatible Alternatives: Parts meeting or exceeding core voltage and current ratings with different package types (DO-214BA) that maintain functional compatibility through equivalent footprint dimensions and mounting characteristics.

Engineering Selection Recommendations
Recommended Primary Substitute: GS1M-LTP
The GS1M-LTP from Micro Commercial Co is the direct equivalent replacement for the GS1ME-TP. It maintains identical voltage and current ratings (1000 V, 1 A), uses the same DO-214AC (SMA) package, and offers superior forward voltage characteristics (1.0 V vs. 1.1 V @ 1 A). The GS1M-LTP holds active product status with ROHS3 compliance and significantly higher inventory availability (88,005 units in stock).
Alternative Substitutes by Application Requirements:
For applications requiring standard recovery characteristics with 1000 V / 1 A ratings in DO-214AC package, the GF1M from onsemi provides equivalent electrical performance. However, this part carries "Not For New Designs" status and should be used only for legacy system maintenance.
For applications where package footprint flexibility exists, the GF1M-E3/5CA and GF1M-E3/67A from Vishay General Semiconductor (SUPERECTIFIER® series) provide 1000 V / 1 A ratings in DO-214BA (GF1) package with active product status and ROHS3 compliance. These parts feature identical forward voltage (1.2 V @ 1 A) and standard recovery characteristics.
For applications with reduced voltage requirements (800 V maximum), the GF1K-E3/67A from Vishay General Semiconductor offers active status and ROHS3 compliance in DO-214BA package.
The CFRA107-G and CURA107-G from Comchip Technology provide 1000 V / 1 A ratings in DO-214AC package with fast recovery characteristics. The CURA107-G features ultrafast recovery (75 ns) suitable for high-frequency switching applications.
The GS1MAFC_R1_00001 from Panjit International Inc. maintains identical electrical specifications (1000 V, 1 A, 1.1 V forward voltage) but uses a different package (DO-221AC/SMAF-C) and should only be selected if footprint compatibility is confirmed.
Parts with "Not For New Designs" status (GF1M, MRA4006T3G) should not be selected for new product development.
The GF1M/1754 from Vishay General Semiconductor, while electrically equivalent, carries RoHS non-compliant status and should not be used in applications requiring RoHS compliance.
Frequently Asked Questions (FAQ)
Q: Can GS1M-LTP directly replace GS1ME-TP without circuit modification?
A: Yes. The GS1M-LTP is a direct equivalent with identical voltage (1000 V) and current (1 A) ratings, same DO-214AC (SMA) package, and compatible operating temperature range (-55°C to 150°C). The improved forward voltage (1.0 V vs. 1.1 V @ 1 A) provides better efficiency with no negative impact on circuit operation.
Q: What is the difference between DO-214AC and DO-214BA packages?
A: Both packages are surface mount rectifier packages with similar footprint dimensions. DO-214AC (SMA) and DO-214BA (GF1) are mechanically compatible for most PCB layouts. Verify specific footprint requirements in your design documentation before substituting between these package types.
Q: Why do some substitutes have higher forward voltage ratings?
A: Forward voltage variation (1.0 V to 1.7 V @ 1 A) reflects different semiconductor manufacturing processes and recovery speed characteristics. Higher forward voltage typically indicates faster recovery times. Selection depends on application requirements for power dissipation and switching frequency.
Q: Can I use an 800 V rated diode (GF1K-E3/67A or MRA4006T3G) instead of the 1000 V GS1ME-TP?
A: No. The GS1ME-TP is rated for 1000 V reverse voltage. Substituting with an 800 V rated part violates the voltage specification and creates risk of diode failure. Use only substitutes rated for 1000 V or higher.
Q: What does "Not For New Designs" product status mean?
A: Parts marked "Not For New Designs" are in mature or declining production phases. While electrically functional, these parts should not be selected for new product development. Use active status parts (GS1M-LTP, CFRA107-G, GF1M-E3/5CA, GF1M-E3/67A) for new designs.
Q: Are all substitute parts ROHS3 compliant?
A: Most substitutes are ROHS3 compliant. The exception is GF1M/1754, which is RoHS non-compliant. Verify RoHS compliance requirements for your application before final part selection.
Q: What is the significance of recovery speed (Standard vs. Fast)?
A: Standard recovery (>500 ns) is suitable for general-purpose rectification and low-frequency applications. Fast recovery (≤500 ns) and ultrafast recovery (75 ns) are required for high-frequency switching applications. The GS1ME-TP uses standard recovery; substitutes with faster recovery are compatible but not required for equivalent performance in standard applications.
Q: Can I use CURA107-G (ultrafast, 75 ns recovery) as a direct replacement?
A: Yes, electrically. The CURA107-G meets the 1000 V / 1 A requirements and uses the same DO-214AC package. However, the higher forward voltage (1.7 V @ 1 A) and ultrafast recovery characteristics are optimized for high-frequency switching. For standard rectification applications, GS1M-LTP or CFRA107-G are more appropriate selections.
Q: What inventory considerations should influence my selection?
A: GS1M-LTP has the highest inventory availability (88,005 units), followed by GF1M (63,580 units) and CURA107-G (13,182 units). For production continuity, prioritize parts with active status and substantial inventory levels.
