SS23L RVG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS23L RVG is a 30V, 2A Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, housed in a DO-219AB (Sub SMA) surface mount package. This component is classified as Active product status and is ROHS3 compliant. The SS23L RVG serves as a fast recovery Schottky diode suitable for low-voltage rectification applications requiring rapid switching characteristics. Equivalent and substitute parts are identified based on matching or exceeding electrical performance parameters while maintaining compatible package and mounting specifications.

Substitute Part Grouping Explanation

Substitute parts for the SS23L RVG are classified into two categories based on electrical parameter compatibility:

Category 1: Direct Equivalent (Same Voltage & Current Rating) Parts matching the 30V reverse voltage and 2A average rectified current specifications are considered direct equivalents. These parts maintain identical electrical performance envelopes and are interchangeable in applications where the original part is specified.

Category 2: Voltage-Upgraded Substitute (Higher Voltage Rating) Parts with higher reverse voltage ratings (40V) but matching 2A current specifications provide enhanced voltage margin. These parts are suitable for applications where the original 30V rating is adequate but higher voltage headroom is beneficial.

Category 3: Current-Reduced Substitutes (Lower Current Rating) Parts with reduced average rectified current ratings (1A or 1.1A) but matching 30V reverse voltage are suitable only for applications where the circuit current requirement does not exceed the substitute part's rating.

Substitution eligibility is determined by the following parameters:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed application requirement
Current - Average Rectified (Io): Must equal or exceed application requirement
Package / Case: Must be compatible with PCB layout
Mounting Type: Must be Surface Mount
Technology: Must be Schottky
Speed: Must be Fast Recovery ≤ 500ns, > 200mA (Io)

Engineering Selection Recommendations

Direct Equivalent Selection (Recommended for Drop-In Replacement)

SS2FL3-M3/H and SS2FL3HM3/H are direct electrical equivalents to the SS23L RVG, matching the 30V reverse voltage and 2A average rectified current specifications. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, are ROHS3 compliant, and housed in the DO-219AB package. SS2FL3HM3/H carries AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade components. Both parts feature extended operating temperature range (-55°C ~ 150°C) compared to the original part (-55°C ~ 125°C).

Voltage-Upgraded Alternative

SS24LW provides a 40V reverse voltage rating with matching 2A current capacity. This part is manufactured by Taiwan Semiconductor Corporation and maintains ROHS3 compliance. The package differs (SOD-123W versus DO-219AB), requiring PCB layout verification before substitution. This part is suitable for applications where higher voltage margin is required.

Current-Reduced Alternatives

SL03-GS18, SS1FL3-M3/H, and SS1FL3HM3/H are rated for 1.1A and 1A respectively, below the original 2A specification. These parts are suitable only for applications where the circuit current requirement does not exceed their rated capacity. All three parts maintain 30V reverse voltage rating and DO-219AB packaging. SL03-GS18 and SS1FL3HM3/H carry automotive qualifications (AEC-Q101).

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can SS24LW be used as a direct replacement for SS23L RVG?

A: SS24LW is electrically compatible for applications where the original 30V rating is adequate. The 40V rating provides higher voltage margin. However, the package differs (SOD-123W versus DO-219AB), requiring verification that the PCB footprint accommodates the substitute package before implementation.

Q: What is the difference between SS2FL3-M3/H and SS2FL3HM3/H?

A: Both parts are identical in electrical specifications (30V, 2A, DO-219AB package). SS2FL3HM3/H carries AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging. SS2FL3-M3/H is supplied in Cut Tape & Digi-Reel packaging. Selection depends on packaging requirements and automotive qualification necessity.

Q: Can I use SS1FL3-M3/H or SS1FL3HM3/H to replace SS23L RVG?

A: These parts are rated for 1A average rectified current, below the original 2A specification. Substitution is valid only if the application circuit current requirement does not exceed 1A. Both parts maintain 30V reverse voltage and DO-219AB package compatibility.

Q: What is the significance of the DO-219AB package compatibility?

A: The DO-219AB package (Sub SMA) is a surface mount form factor. Parts sharing this package designation are mechanically and electrically compatible with the same PCB footprint. SS24LW uses SOD-123W package, which differs and requires PCB layout verification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SS24LW, SL03-GS18, SS1FL3-M3/H, SS1FL3HM3/H, SS2FL3-M3/H, SS2FL3HM3/H) are ROHS3 compliant, matching the original SS23L RVG compliance status.

Q: Which substitute part has the lowest forward voltage drop?

A: SL03-GS18 exhibits the lowest forward voltage drop at 430 mV @ 1.1A. However, this part is rated for 1.1A current, limiting its application to circuits not exceeding this current level.

Q: What is the operating temperature range difference between SS23L RVG and its substitutes?

A: SS23L RVG operates from -55°C to 125°C. Vishay-manufactured substitutes (SS1FL3 series and SS2FL3 series) extend the upper limit to 150°C, providing 25°C additional thermal margin. This extended range is beneficial for high-temperature applications.

Q: Can I substitute based on package type alone?

A: No. Package compatibility is necessary but not sufficient for substitution. Electrical parameters (voltage, current, forward voltage drop, reverse leakage) must also meet or exceed application requirements. Both package and electrical specifications must be verified.
