Substitution Categories:

Parametric Equivalents maintain identical electrical specifications and are direct functional replacements. These include SSL23 (Tape & Reel packaging variant) and SSL23H (automotive-qualified variant with AEC-Q101 certification).

Direct Manufacturer Equivalents from Vishay General Semiconductor (SL23-E3/52T, SL23-E3/5BT, SL23-M3/52T) provide identical electrical performance with forward voltage specifications of 440 mV @ 2A, representing a minor variation within acceptable design margins.

Similar Parts meet the core electrical requirements (30V, 2A, Schottky, DO-214AA SMB) but may exhibit variations in forward voltage, reverse leakage current, or temperature range. These include components from Diodes Incorporated (B230-13-F, B230A-13-F, B230Q-13-F) and Microchip Technology (5818SMJ/TR13). The B330B-13-F variant supports higher current (3A) and is suitable for applications requiring additional current margin.

Engineering Selection Recommendations

Recommended Primary Substitutes:

SSL23 and SSL23H from Taiwan Semiconductor Corporation are the preferred direct replacements for SSL23 R5G. Both maintain identical electrical specifications (30V, 2A, 410 mV forward voltage) and operating temperature range. SSL23H includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade reliability. Both are currently in active production status with adequate inventory availability.

Recommended Secondary Substitutes:

Vishay General Semiconductor SL23-E3/52T, SL23-E3/5BT, and SL23-M3/52T provide functional equivalence with a 30 mV increase in forward voltage (440 mV @ 2A versus 410 mV @ 2A). This variation is within typical design margins for Schottky diode applications. All three variants are RoHS3 compliant and actively produced.

Conditional Substitutes:

Diodes Incorporated B230-13-F, B230Q-13-F, and B330B-13-F are suitable where forward voltage tolerance permits. The B230 series exhibits 500 mV forward voltage and 500 µA reverse leakage, representing increased power dissipation compared to the SSL23 R5G. B230Q-13-F includes AEC-Q101 automotive qualification. B330B-13-F supports 3A current rating, providing design margin for applications approaching 2A limits.

Not Recommended:

Microchip Technology 5818SMJ/TR13 is not RoHS3 compliant and exhibits reduced current rating (1A) and elevated reverse leakage (1 mA @ 30V). This part is suitable only for applications with reduced current requirements and non-RoHS environments.

B230A-13-F uses DO-214AC (SMA) package instead of DO-214AA (SMB), requiring PCB layout modification and is not recommended as a direct substitute without design review.

Frequently Asked Questions (FAQ)

Q: Can SSL23 R5G be replaced with SSL23 in existing designs?

A: Yes. SSL23 is a parametric equivalent with identical electrical specifications and operating temperature range. The primary difference is packaging format (Tape & Reel versus bulk). No circuit modifications are required.

Q: What is the difference between SSL23 and SSL23H?

A: Both parts are electrically identical with 30V, 2A, and 410 mV forward voltage specifications. SSL23H includes AEC-Q101 automotive qualification and is suitable for automotive applications requiring formal qualification documentation. Standard SSL23 is appropriate for general industrial and consumer applications.

Q: Can Vishay SL23-E3/52T replace SSL23 R5G directly?

A: Yes, with design consideration. SL23-E3/52T maintains 30V, 2A ratings and identical operating temperature range. Forward voltage is 440 mV @ 2A compared to 410 mV @ 2A for SSL23 R5G. This 30 mV difference increases power dissipation by approximately 60 mW at 2A operation. Verify thermal design margins before substitution.

Q: Are Diodes Incorporated B230 series parts suitable replacements?

A: B230-13-F and B230Q-13-F are functionally compatible for 30V, 2A applications. Forward voltage is 500 mV @ 2A, resulting in 180 mW additional power dissipation at 2A compared to SSL23 R5G. Reverse leakage is 500 µA versus 400 µA. These differences are acceptable in applications with adequate thermal design margin. B230A-13-F uses SMA package and requires PCB modification.

Q: Why is B330B-13-F listed as a substitute if it has 3A rating?

A: B330B-13-F maintains 30V reverse voltage and DO-214AA SMB package compatibility. The 3A current rating provides design margin for applications approaching 2A limits. Forward voltage is 500 mV @ 3A. This part is suitable where increased current capacity is beneficial, though not required for 2A operation.

Q: Is the Microchip 5818SMJ/TR13 a viable substitute?

A: No. While the 5818SMJ/TR13 maintains 30V rating and DO-214AA package, it is rated for only 1A average rectified current, insufficient for 2A applications. Additionally, it is RoHS non-compliant and exhibits 1 mA reverse leakage at 30V, significantly higher than SSL23 R5G specifications. This part is not recommended.

Q: What packaging formats are available for SSL23 equivalents?

A: SSL23 is available in Tape & Reel (TR) format. SL23-E3/52T is supplied in Cut Tape (CT). SL23-E3/5BT and SL23-M3/52T are supplied in Tape & Reel (TR). All variants use DO-214AA (SMB) surface mount package. Verify packaging requirements for automated assembly processes.

Q: Are all recommended substitutes RoHS3 compliant?

A: SSL23, SSL23H, and all Vishay SL23 variants are RoHS3 compliant. Diodes Incorporated B230 series parts are RoHS3 compliant. Microchip 5818SMJ/TR13 is RoHS non-compliant. Verify RoHS compliance requirements for your application before final part selection.

Q: What is the temperature operating range difference between SSL23 R5G and B230 series?

A: SSL23 R5G operates -55°C to 125°C. B230 series parts operate -65°C to 150°C, providing extended low-temperature and high-temperature capability. This extended range is beneficial for applications with extreme environmental requirements but is not necessary for standard -55°C to 125°C specifications.
