Engineering Selection Recommendations
Parametric Equivalent - Direct Replacement:
SS26H (Taiwan Semiconductor Corporation) is the primary equivalent for SS26 R5G. Both parts maintain identical electrical specifications (60V, 2A, 700mV forward voltage, 400µA reverse leakage) and identical DO-214AA (SMB) package configuration. SS26H is currently active in production and carries AEC-Q101 automotive qualification, providing enhanced reliability documentation. This part is suitable for direct substitution without circuit redesign.
Parametric Equivalent - Package Variant:
SS26 (EVVO Semi) provides equivalent electrical performance (60V, 2A, 700mV forward voltage) in DO-214AC (SMA) package. The reverse leakage specification increases to 500µA at 60V. This part is suitable for applications where SMA package footprint is acceptable. High inventory availability (35,200 units) supports production continuity.
Similar Parts - Same Current Rating:
B260-13-F, B260A-13-F, and B260Q-13-F (Diodes Incorporated) all provide 60V, 2A Schottky rectification with 700mV forward voltage specification. B260-13-F and B260Q-13-F maintain DO-214AA (SMB) package compatibility. B260Q-13-F carries AEC-Q101 automotive qualification. Reverse leakage increases to 500µA across this family. These parts are suitable for direct substitution in non-automotive applications; B260Q-13-F is suitable for automotive applications.
Similar Parts - Higher Current Rating:
B360B series (Vishay General Semiconductor - Diodes Division) provides 60V, 3A Schottky rectification in DO-214AA (SMB) package. Forward voltage reduces to 660mV at 3A, and reverse leakage reduces to 100µA at 60V. These parts are suitable for applications requiring higher current capacity or lower reverse leakage characteristics. Multiple packaging options (E3/52T, E3/5BT, M3/52T, M3/5BT) provide supply flexibility.

Frequently Asked Questions (FAQ)
Q: Can SS26 R5G be directly replaced with SS26H?
A: Yes. SS26H is a parametric equivalent with identical electrical specifications (60V, 2A, 700mV forward voltage, 400µA reverse leakage) and identical DO-214AA (SMB) package. SS26H is currently in active production with AEC-Q101 automotive qualification.
Q: What is the difference between DO-214AA (SMB) and DO-214AC (SMA) packages?
A: Both are surface mount Schottky diode packages with different physical dimensions. DO-214AA (SMB) is larger than DO-214AC (SMA). Package selection depends on PCB footprint design. Electrical performance is independent of package type.
Q: Can B260Q-13-F replace SS26 R5G in automotive applications?
A: Yes, with design verification. B260Q-13-F provides identical voltage (60V) and current (2A) ratings with matching forward voltage (700mV @ 2A) and DO-214AA (SMB) package. B260Q-13-F carries AEC-Q101 automotive qualification. Reverse leakage increases from 400µA to 500µA; circuit design must accommodate this specification change.
Q: Why do B360B series parts have lower reverse leakage?
A: B360B series provides 3A current capacity with 100µA reverse leakage at 60V, compared to 400µA for SS26 R5G at 2A. Lower reverse leakage is a characteristic of higher current-rated Schottky diodes. These parts are suitable for applications requiring lower leakage current or higher current capacity.
Q: Is the EVVO Semi SS26 suitable for my application if I use SMA package?
A: EVVO Semi SS26 provides equivalent electrical specifications (60V, 2A, 700mV forward voltage) in DO-214AC (SMA) package. Reverse leakage increases to 500µA. This part is suitable if your PCB design accommodates SMA package footprint and the higher reverse leakage specification does not affect circuit performance.
Q: What does AEC-Q101 qualification mean?
A: AEC-Q101 is an automotive electronics council qualification standard for discrete semiconductors. Parts carrying this qualification have undergone enhanced reliability testing and documentation suitable for automotive and high-reliability applications. SS26H, B260Q-13-F, and B160BQ-13-F carry this qualification.
Q: Can I use B160BQ-13-F as a substitute for SS26 R5G?
A: B160BQ-13-F is not suitable as a direct substitute. While it maintains 60V voltage rating and DO-214AA (SMB) package, current capacity is reduced to 1A compared to 2A for SS26 R5G. This part is suitable only for applications requiring 1A or less current.
Q: What inventory considerations apply to these substitute parts?
A: B260A-13-F (Diodes Incorporated) provides the highest inventory availability at 155,200 units in SMA package. B260-13-F and B260Q-13-F each maintain approximately 44,000 units in SMB package. SS26H maintains 6,772 units. EVVO Semi SS26 maintains 35,200 units. Inventory levels support production requirements across multiple sourcing options.
