GF1D Equivalent & Substitute Parts
Part Overview
The GF1D is a general-purpose rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 1 A average rectified current in a DO-214AC (SMA) surface mount package. This part is classified as Not For New Designs, indicating it has reached end-of-life status. Identification of equivalent and substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where legacy component specifications remain applicable.

Substitute Part Grouping Explanation
Substitution of the GF1D is determined by matching the following critical electrical and mechanical parameters:
Mandatory Matching Parameters:
- Voltage - DC Reverse (Vr) (Max): 200 V
- Current - Average Rectified (Io): 1 A
- Package / Case: DO-214AC or SMA equivalent
- Mounting Type: Surface Mount
Acceptable Variation Parameters:
- Voltage - Forward (Vf) (Max) @ If: Range 920 mV to 1.3 V @ 1 A
- Reverse Recovery Time (trr): 25 ns to 2 µs (standard to fast recovery)
- Current - Reverse Leakage @ Vr: 5 µA @ 200 V (consistent across all candidates)
- Operating Temperature - Junction: Minimum -55°C to -65°C; Maximum 150°C to 175°C
- RoHS Status: ROHS3 Compliant (required)
Substitute parts must maintain electrical equivalence within these parameter windows while preserving package compatibility and regulatory compliance. Parts with active product status are preferred for new procurement; discontinued parts are listed for reference only.

Engineering Selection Recommendations
Primary Substitutes (Active Status, Full Compliance):
ES1D-LTP (Micro Commercial Co) and CMR1-02M TR13 PBFREE (Central Semiconductor Corp) are the preferred substitutes. Both maintain the full operating temperature range of the original GF1D (-65°C to 175°C or -65°C to 150°C respectively), ensuring compatibility in extended temperature applications. Both are ROHS3 compliant and carry active product status with substantial inventory availability.
ES1D-13-F (Diodes Incorporated) offers the lowest forward voltage drop (920 mV @ 1 A) and fastest recovery time (25 ns), providing improved efficiency characteristics while maintaining full electrical equivalence. This part is actively produced with high inventory levels.
Secondary Substitutes (Active Status, Reduced Temperature Range):
ES1D (EVVO Semi), RS1D (Taiwan Semiconductor Corporation), CGRA4003-G (Comchip Technology), and CURA103-G (Comchip Technology) are electrically equivalent but operate within a reduced temperature range (-55°C to 150°C). These parts are suitable for applications not requiring the extended low-temperature performance of the original GF1D.
Discontinued Reference:
ES1D R3G (Taiwan Semiconductor Corporation) is listed as discontinued at DiGi Electronics and should not be selected for new procurement despite electrical equivalence.
Packaging Considerations:
All substitute parts are available in DO-214AC (SMA) surface mount package. Packaging format variations (Cut Tape, Tape & Reel, Bulk) do not affect electrical or mechanical compatibility; selection depends on procurement and assembly requirements.
Frequently Asked Questions (FAQ)
Q: Can ES1D-LTP directly replace GF1D in all applications?
A: ES1D-LTP meets all mandatory electrical parameters (200 V, 1 A, DO-214AC package) and maintains the full operating temperature range (-65°C to 175°C). Direct substitution is valid for applications operating within these specifications.
Q: What is the difference between standard recovery and fast recovery diodes in this comparison?
A: The GF1D exhibits standard recovery characteristics with a reverse recovery time (trr) of 2 µs. Substitute parts with fast recovery (trr ≤ 500 ns) such as ES1D-13-F (25 ns) and CURA103-G (50 ns) switch faster, reducing switching losses and electromagnetic interference. Fast recovery diodes are backward compatible with standard recovery applications.
Q: Are there compatibility issues between Cut Tape and Tape & Reel packaging formats?
A: Packaging format (Cut Tape, Tape & Reel, Bulk) affects procurement and assembly logistics only. Electrical and mechanical specifications remain identical. Component selection should be based on manufacturing process requirements, not electrical performance.
Q: Why do some substitute parts have a maximum operating temperature of 150°C instead of 175°C?
A: Operating temperature range is a design specification set by each manufacturer. Parts rated to 150°C are suitable for applications with maximum junction temperatures up to 150°C. Applications requiring operation above 150°C must use parts with higher temperature ratings, such as ES1D-LTP or CMR1-02M variants.
Q: Is forward voltage drop (Vf) variation significant for substitution?
A: Forward voltage drop varies from 920 mV to 1.3 V across the substitute parts. In low-power applications, this variation has minimal impact. In high-current or thermally sensitive circuits, lower Vf values (ES1D-13-F at 920 mV) reduce power dissipation and heat generation. Circuit analysis determines whether Vf variation is acceptable.
Q: What does ROHS3 compliance mean for component selection?
A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All listed substitute parts are ROHS3 compliant, ensuring regulatory equivalence with the original GF1D.
Q: Can I use a substitute part with a lower reverse recovery time in a legacy design?
A: Yes. Faster recovery times (lower trr values) are backward compatible with designs specified for slower recovery. Fast recovery diodes reduce switching losses and are suitable for retrofit applications without circuit modification.
