Engineering Selection Recommendations

Primary Equivalent (Direct Replacement):

SS26T3G (onsemi) is the recommended primary equivalent. This part maintains the same base product line (SS26), is manufactured by the original supplier, and carries active product status. It provides improved reverse leakage characteristics (200 µA vs. 400 µA) and lower forward voltage (630 mV vs. 700 mV), resulting in reduced power dissipation. Operating temperature range extends to 150°C maximum, supporting broader thermal applications.

Secondary Equivalent (Functional Match):

MBRS260T3G (onsemi) provides identical electrical specifications to SS26T3G with equivalent performance characteristics. Both parts are suitable for direct substitution in new designs.

Multi-Manufacturer Alternatives (60V/2A, DO-214AA SMB):

B260-13-F and B260Q-13-F (Diodes Incorporated) are functionally equivalent 60V/2A Schottky diodes in DO-214AA (SMB) packaging. B260Q-13-F carries AEC-Q101 automotive qualification and is suitable for automotive and industrial applications requiring third-party qualification. Both parts exhibit higher reverse leakage (500 µA) compared to the original SS26 specification.

SK26 (Good-Ark Semiconductor) provides equivalent 60V/2A performance with reduced reverse leakage (150 µA) and extended temperature range (-55°C to +150°C). This part is suitable for applications requiring lower leakage current.

Current Rating Variants (Derating/Upgrading):

B160B-13-F and B160BQ-13-F (Diodes Incorporated) are 60V/1A Schottky diodes suitable for applications where 2A capacity is not required or where current derating is acceptable. B160BQ-13-F includes AEC-Q101 automotive qualification.

B360B-13-F (Diodes Incorporated) and B360B-E3/52T (Vishay) are 60V/3A Schottky diodes for applications requiring higher current capacity or thermal margin. Both parts carry AEC-Q101 automotive qualification and support extended temperature ranges.

Package Variant (SMA Alternative):

B260A-13-F (Diodes Incorporated) is a 60V/2A Schottky diode in DO-214AC (SMA) surface mount package. This part is electrically equivalent but requires PCB layout modification due to different package footprint. Use only when SMA package is specified or preferred.

A: Both parts are 60V/2A Schottky diodes in DO-214AA (SMB) packaging with identical electrical specifications. B260Q-13-F includes AEC-Q101 automotive qualification and is supplied in Tape & Reel (TR) packaging, while B260-13-F is supplied in Cut Tape (CT) & Digi-Reel® packaging. Select B260Q-13-F for automotive applications requiring third-party qualification.

Q: Can B160B-13-F (1A) be used instead of SS26 (2A)?

A: B160B-13-F is a partial substitute suitable only for applications where the circuit current requirement does not exceed 1A. If the application requires 2A capacity, this part is not suitable. Use only when current derating is acceptable and verified by circuit analysis.

Q: Can B360B-13-F (3A) be used instead of SS26 (2A)?

A: Yes. B360B-13-F is a functional upgrade suitable for applications requiring higher current capacity or improved thermal margin. The 60V reverse voltage rating and DO-214AA (SMB) package are identical. This part is suitable for direct substitution with the benefit of additional current capacity.

Q: Why does B260A-13-F have a different package (SMA vs. SMB)?

A: B260A-13-F uses DO-214AC (SMA) package instead of DO-214AA (SMB). While electrically equivalent, the physical footprint differs. This part requires PCB layout modification and is suitable only when SMA package is specified or when footprint compatibility is verified.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry reliability qualification standard. Parts carrying this designation (B260Q-13-F, B160BQ-13-F, B360B-13-F) have undergone additional testing and validation for automotive applications. Use these parts for automotive designs or applications requiring automotive-grade reliability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the operating temperature range difference between SS26 and SS26T3G?

A: SS26 operates from -65°C to +125°C, while SS26T3G operates from -55°C to +150°C. SS26T3G provides extended maximum temperature capability (+150°C vs. +125°C), suitable for higher-temperature applications. The minimum operating temperature is slightly higher (-55°C vs. -65°C).

Q: Can SK26 be used as a substitute for SS26?

A: Yes. SK26 (Good-Ark Semiconductor) is a functional equivalent with 60V/2A ratings in DO-214AA (SMB) packaging. It provides improved reverse leakage characteristics (150 µA vs. 400 µA) and extended temperature range (-55°C to +150°C). This part is suitable for direct substitution.

Q: What is the difference in forward voltage between SS26 and MBRS260T3G?

A: SS26 specifies 700 mV forward voltage at 2A, while MBRS260T3G specifies 630 mV at 2A. The lower forward voltage of MBRS260T3G results in reduced power dissipation and improved efficiency. Both values are within acceptable Schottky diode performance ranges.
