Substitute Part Grouping Explanation

Substitution of the SSL23HR5G is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 30 V
Current - Average Rectified (Io): 2 A
Technology: Schottky
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Parametric Equivalent Parts maintain identical electrical specifications and automotive qualification. These parts are direct functional replacements with no design modifications required.

Similar Parts share the same voltage and package specifications but differ in current rating, forward voltage characteristics, or temperature range. These parts are suitable for applications where the SSL23HR5G specifications exceed design requirements or where alternative compliance profiles are acceptable.

Engineering Selection Recommendations

For Direct Replacement (Automotive Applications):

SSL23H is the primary recommended substitute for SSL23HR5G. Both parts are manufactured by Taiwan Semiconductor Corporation, share identical electrical specifications (30 V, 2 A, 410 mV forward voltage), carry automotive-grade qualification with AEC-Q101 certification, and are packaged in DO-214AA (SMB). SSL23H is currently in active production status, ensuring long-term availability and supply chain continuity.

For Automotive Applications with Alternative Manufacturer:

B230Q-13-F (Diodes Incorporated) provides equivalent electrical performance with automotive-grade qualification and AEC-Q101 certification. This part maintains the 30 V / 2 A specifications and DO-214AA (SMB) package. Forward voltage is specified at 500 mV @ 2 A, representing a 90 mV increase compared to SSL23HR5G. This part is actively produced and widely available.

For Non-Automotive or Relaxed Compliance Requirements:

B230-13-F (Diodes Incorporated) offers 30 V / 2 A performance in DO-214AA (SMB) package without automotive qualification. This part is suitable for industrial and consumer applications where AEC-Q101 certification is not required. Forward voltage specification is 500 mV @ 2 A.

For Current-Derating Applications:

B330B-13-F (Diodes Incorporated) provides 30 V / 3 A capability in DO-214AA (SMB) package with automotive-grade qualification and AEC-Q101 certification. This part is suitable for applications where the SSL23HR5G 2 A rating is marginal and additional current headroom is beneficial. Forward voltage is specified at 500 mV @ 3 A.

Parts Not Recommended for New Designs:

SK13-LTP is designated "Not For New Designs" and should not be selected for new development projects despite meeting basic electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can SSL23 (non-H variant) be used as a direct replacement for SSL23HR5G in automotive applications?

A: SSL23 shares identical electrical specifications with SSL23HR5G but does not carry automotive-grade designation or AEC-Q101 qualification. Use of SSL23 in automotive applications requires verification that the application does not mandate automotive-grade components. For automotive designs, SSL23H is the appropriate substitute.

Q: What is the difference between B230-13-F and B230Q-13-F?

A: Both parts are manufactured by Diodes Incorporated and share 30 V / 2 A specifications in DO-214AA (SMB) package. B230Q-13-F carries automotive-grade qualification with AEC-Q101 certification, while B230-13-F does not. B230Q-13-F is suitable for automotive applications; B230-13-F is suitable for industrial and consumer applications.

Q: Why is B230A-13-F listed as a similar part if the package is different?

A: B230A-13-F is packaged in DO-214AC (SMA) rather than DO-214AA (SMB). While electrical specifications are equivalent (30 V / 2 A), the different package requires PCB layout modification and is not a direct mechanical substitute. This part is listed for reference in applications where package change is acceptable.

Q: Can 1 A rated parts (5818SMJ/TR13, SK13-TP, SK13E3/TR13) replace the 2 A SSL23HR5G?

A: 1 A rated parts are not suitable for applications requiring 2 A average rectified current. These parts are listed as similar alternatives only for applications where the design current requirement is 1 A or less. Use of undersized current-rated components in 2 A applications will result in thermal stress and potential component failure.

Q: What is the significance of the forward voltage difference between SSL23HR5G (410 mV) and substitute parts (500 mV)?

A: The 90 mV forward voltage increase in substitute parts (B230-13-F, B230Q-13-F, B330B-13-F) results in higher power dissipation at rated current. For a 2 A load, this represents approximately 180 mW additional dissipation. Thermal analysis of the PCB and component mounting is required to confirm acceptable junction temperature operation within the specified range.

Q: Is RoHS3 compliance maintained across all recommended substitutes?

A: SSL23H, B230-13-F, B230Q-13-F, and B330B-13-F are all RoHS3 compliant. Compliance status is maintained for these substitutes. Verify RoHS status for any additional parts under consideration.

Q: What is the operating temperature range difference between SSL23HR5G and substitute parts?

A: SSL23HR5G and SSL23H are specified for -55°C to 125°C junction temperature. B230-13-F, B230Q-13-F, and B330B-13-F extend the upper limit to 150°C. SK13E3/TR13 extends to 175°C. Higher temperature ratings provide additional thermal margin but do not affect substitution suitability if the application operates within the SSL23HR5G temperature range.

Q: Can SSL23HR5G be substituted with parts rated for higher voltage (e.g., 40 V or 60 V)?

A: Substitution with higher voltage-rated parts is not addressed in this reference. Parts must maintain the 30 V DC reverse voltage specification to ensure proper circuit operation and component reliability within the design's voltage environment.
