Substitute Part Grouping Explanation

Substitution of the SB360 is determined by the following critical electrical and mechanical parameters:

Voltage Rating: All substitute parts must maintain a minimum DC reverse voltage rating of 60 V to ensure equivalent reverse bias protection.

Current Rating: Substitute parts must support a minimum average rectified current of 3 A. Parts with higher current ratings (3.3 A or greater) are acceptable as they provide additional design margin.

Package Compatibility: The DO-201AD axial through-hole package is the primary form factor. Substitute parts in equivalent axial packages (DO-201AA, DO-27) maintain mechanical and electrical compatibility with existing PCB layouts.

Technology: All substitutes employ Schottky diode technology with fast recovery characteristics (≤ 500ns, > 200mA), ensuring consistent switching performance.

Forward Voltage: Forward voltage specifications range from 620 mV to 740 mV at rated current, representing acceptable variation within Schottky diode manufacturing tolerances.

Reverse Leakage: Reverse leakage current specifications range from 500 µA to 2 mA at 60 V, all within acceptable limits for rectification applications.

Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

SB360-E3/54 provides 52,650 units in stock with identical temperature range extension.

onsemi Alternatives (Same Manufacturer):

MBR360RLG and MBR360G are onsemi products with equivalent electrical specifications (60 V, 3 A, 740 mV forward voltage). Both feature extended operating temperature to 150°C. MBR360RLG is packaged in cut tape format with 20,344 units available. MBR360G is supplied in bulk packaging with 59,500 units in stock. These parts use DO-201AA and DO-27 axial packages, which are mechanically compatible with DO-201AD layouts.

Higher Current Capability:

SR806 B0G (Taiwan Semiconductor Corporation) provides 8 A average rectified current in a DO-201AD package at 60 V rating. This part offers additional design margin for applications requiring higher current capacity while maintaining the same voltage class and package form factor.

Current-Limited Substitutes:

SR206 (Taiwan Semiconductor Corporation) is rated for 2 A average rectified current, below the 3 A specification of the SB360. This part is suitable only for applications where the actual circuit current requirement does not exceed 2 A. The package is DO-204AC (DO-15), which differs from the DO-201AD form factor.

This part operates across -40°C to 150°C with 12,200 units in stock. The higher current rating and lower forward voltage provide enhanced efficiency characteristics.

Frequently Asked Questions (FAQ)

Q: Can I use SR206 as a direct replacement for SB360?

A: SR206 is not a direct replacement. While both are 60 V Schottky diodes, SR206 is rated for 2 A average rectified current compared to SB360's 3 A rating. SR206 is suitable only if your circuit current requirement does not exceed 2 A. Additionally, SR206 uses a DO-204AC (DO-15) package, which differs mechanically from the SB360's DO-201AD package.

Q: What is the difference between MBR360RLG and MBR360G?

A: Both parts are onsemi MBR360 variants with identical electrical specifications (60 V, 3 A, 740 mV forward voltage). The primary difference is packaging: MBR360RLG is supplied in cut tape format, while MBR360G is supplied in bulk. MBR360G offers higher inventory (59,500 units vs. 20,344 units). Both use DO-201AA and DO-27 axial packages, which are mechanically compatible with DO-201AD layouts.

Q: Is SB360-E3/54 a suitable replacement for the obsolete SB360?

A: Yes. SB360-E3/54 (Vishay) is a direct functional replacement with identical 60 V, 3 A electrical specifications in a DO-201AD package. It has active product status with 52,650 units in stock and extends the operating temperature range to 150°C compared to the original SB360's 125°C maximum.

Q: Can I use SR806 B0G instead of SB360?

A: Yes, with design margin consideration. SR806 B0G provides 8 A average rectified current at 60 V in a DO-201AD package, exceeding the SB360's 3 A rating. This higher current capability is suitable for applications requiring additional design margin or future current growth. The part is electrically and mechanically compatible.

Q: What is the difference between SR306-TP, SR306-AP, and SR306-BP?

A: All three are Micro Commercial Co SR306 variants with identical electrical specifications (60 V, 3 A, 720 mV forward voltage) in DO-201AD packages. The differences are packaging format and inventory levels: SR306-TP is cut tape (7,489 units), SR306-AP is bulk (751 units), and SR306-BP is bulk (868 units). All operate across -55°C to 125°C.

Q: Does 31DQ06 offer any advantages over SB360?

A: 31DQ06 (SMC Diode Solutions) provides two advantages: higher current rating (3.3 A vs. 3 A) and lower forward voltage (620 mV @ 3 A vs. 740 mV @ 3 A). The lower forward voltage reduces power dissipation and heat generation. However, the operating temperature range is narrower (-40°C to 150°C vs. -65°C to 125°C for SB360), which may be a limitation in extreme cold environments.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original SB360 component.

Q: What package compatibility should I consider when selecting a substitute?

A: The SB360 uses a DO-201AD axial through-hole package. Direct package matches include SB360-T, SB360-E3/54, 31DQ06, SR306-TP, SR306-AP, SR306-BP, and SR806 B0G. MBR360RLG and MBR360G use DO-201AA and DO-27 packages, which are mechanically compatible axial formats. SR206 uses DO-204AC (DO-15), a different axial package that may require PCB layout verification.
