Substitute Part Grouping Explanation

Substitute parts for the SS23L M2G are grouped based on the following substitution criteria:

Primary Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 30 V
Package / Case: DO-219AB (Sub SMA / SMF)
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
RoHS Status: ROHS3 Compliant

Current Rating Grouping:

Group 1 - Full Current Rating Match (2A): Parts with 2A average rectified current capacity are direct substitutes for the SS23L M2G. These include SS2FL3-M3/H, SS2FL3HM3/H from Vishay General Semiconductor - Diodes Division. These parts maintain identical current handling capacity and voltage specifications.

Group 2 - Reduced Current Rating (1A): Parts with 1A average rectified current capacity (SS1FL3-M3/H, SS1FL3HM3/H) are suitable for applications where the full 2A capacity is not required. These maintain the 30V reverse voltage rating and fast recovery characteristics.

Group 3 - Reduced Current Rating (1.1A): The SL03-GS18 from Vishay General Semiconductor - Diodes Division provides 1.1A capacity, positioned between the 1A and 2A options.

All substitute parts share the same 30V reverse voltage specification, DO-219AB package, surface mount configuration, and fast recovery speed performance. Forward voltage characteristics vary slightly across the current ratings due to the relationship between forward voltage drop and current capacity.

Engineering Selection Recommendations

Direct Substitutes (2A Current Rating):

SS2FL3-M3/H and SS2FL3HM3/H are direct electrical equivalents to the SS23L M2G, both rated for 2A average rectified current at 30V reverse voltage. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain ROHS3 compliance and Active product status. SS2FL3HM3/H carries AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability. The forward voltage specification of 540 mV @ 2A is slightly higher than the SS23L M2G at 500 mV @ 2A, resulting in marginally increased power dissipation. Reverse leakage current is lower at 200 µA compared to 400 µA for the main part.

Reduced Current Substitutes (1A Rating):

SS1FL3-M3/H and SS1FL3HM3/H are suitable for applications where 1A average rectified current capacity is sufficient. Both maintain the 30V reverse voltage rating and fast recovery characteristics. SS1FL3HM3/H includes AEC-Q101 automotive qualification. Forward voltage at 480 mV @ 1A is lower than the main part, indicating improved efficiency at reduced current levels. Operating temperature range matches the main part at -55°C to 150°C.

Intermediate Current Substitute (1.1A Rating):

SL03-GS18 provides 1.1A average rectified current capacity, positioned between the 1A and 2A options. This part exhibits the lowest forward voltage at 430 mV @ 1.1A and the lowest reverse leakage current at 130 µA @ 30V. The maximum operating temperature is specified at 125°C, which is lower than the main part's 150°C maximum junction temperature.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and Active product status. Inventory availability is substantial across all options, with SS1FL3HM3/H showing the highest stock level at 68,655 pieces.

Frequently Asked Questions (FAQ)

Q: Can SS2FL3-M3/H or SS2FL3HM3/H be used as direct replacements for SS23L M2G?

A: Yes. Both parts are rated for 2A average rectified current at 30V reverse voltage with identical DO-219AB surface mount packaging. The forward voltage specification is slightly higher (540 mV vs. 500 mV @ 2A), resulting in approximately 40 mV additional voltage drop. This difference is acceptable in most applications but should be evaluated for thermal management in high-current or high-frequency switching scenarios.

Q: What is the difference between SS1FL3-M3/H and SS1FL3HM3/H?

A: Both parts are electrically identical with 1A average rectified current capacity at 30V reverse voltage. The primary difference is that SS1FL3HM3/H carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring enhanced reliability testing and qualification standards. SS1FL3-M3/H is supplied in Cut Tape (CT) & Digi-Reel® packaging, while SS1FL3HM3/H is supplied in Tape & Reel (TR) packaging.

Q: Can I use a 1A-rated part (SS1FL3-M3/H or SS1FL3HM3/H) in place of the 2A-rated SS23L M2G?

A: Substitution is possible only if the application circuit does not require the full 2A current capacity. The 1A-rated parts will function correctly at currents up to 1A. Exceeding 1A average rectified current will cause the 1A-rated parts to operate outside their specified limits. Forward voltage is lower at 480 mV @ 1A, providing improved efficiency at reduced current levels.

Q: What is the difference between SL03-GS18 and the other 1A-rated substitutes?

A: SL03-GS18 is rated for 1.1A average rectified current, providing slightly higher current capacity than the 1A-rated parts. It exhibits the lowest forward voltage (430 mV @ 1.1A) and lowest reverse leakage current (130 µA @ 30V) among all substitutes. The maximum operating junction temperature is 125°C, which is lower than the main part's 150°C specification. This part is supplied in Tape & Reel (TR) packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SS2FL3-M3/H, SS2FL3HM3/H, SS1FL3-M3/H, SS1FL3HM3/H, and SL03-GS18) are ROHS3 compliant and maintain Active product status.

Q: What is the significance of the AEC-Q101 qualification on SS2FL3HM3/H and SS1FL3HM3/H?

A: AEC-Q101 is an automotive electronics qualification standard. Parts carrying this qualification have undergone enhanced reliability testing and are approved for use in automotive applications. If your application requires automotive-grade components, select SS2FL3HM3/H (2A) or SS1FL3HM3/H (1A).

Q: How do forward voltage differences affect circuit performance?

A: Forward voltage drop directly impacts power dissipation and heat generation. The SS23L M2G specifies 500 mV @ 2A, while SS2FL3-M3/H and SS2FL3HM3/H specify 540 mV @ 2A. At 2A continuous current, this 40 mV difference results in an additional 80 mW power dissipation. In high-frequency switching applications or circuits with tight thermal budgets, this difference should be evaluated.

Q: What packaging options are available for the substitute parts?

A: Substitute parts are supplied in either Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR) packaging formats. All parts use the same DO-219AB surface mount package. Packaging selection depends on manufacturing and assembly requirements. Tape & Reel (TR) packaging is standard for high-volume automated assembly.

Q: Can I mix different substitute parts in the same circuit design?

A: All substitute parts share the same 30V reverse voltage rating, DO-219AB package, and fast recovery characteristics, making them mechanically and electrically compatible within the same circuit. However, mixing parts with different current ratings (1A, 1.1A, or 2A) in parallel or series configurations requires careful circuit analysis to ensure proper current distribution and voltage sharing.
