Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

B360B-13-F and B360BQ-13-F are direct equivalents from Diodes Incorporated with identical electrical specifications to the B360B-13. Both parts are active products with ROHS3 compliance and AEC-Q101 automotive qualification. B360B-13-F is available in Cut Tape and Digi-Reel packaging, while B360BQ-13-F is supplied in Tape & Reel format. These parts are the primary recommendation for direct substitution.

Equivalent Performance (3A Rating, 60V Voltage Class):

CDBB360-G (Comchip Technology), CMSH3-60M TR13 PBFREE (Central Semiconductor Corp), SK36B-LTP (Micro Commercial Co), STPS3L60U, and STPS3L60UY (STMicroelectronics) all maintain the 60V reverse voltage and 3A current rating. STPS3L60U and STPS3L60UY offer improved forward voltage characteristics (620 mV versus 700 mV at 3A) and reduced reverse leakage current (150 µA versus 500 µA). STPS3L60UY includes AEC-Q101 automotive qualification. SS36B (MDD) provides parametric equivalence with identical electrical specifications to the B360B-13.

Reduced Current Rating (1A Rating, 60V Voltage Class):

STPS160U and STPS160UY are rated for 1A average rectified current, representing a partial substitute suitable only for applications where the circuit current requirement does not exceed 1A. STPS160UY includes AEC-Q101 automotive qualification. These parts are not suitable for circuits designed for 3A operation.

Compliance Considerations:

All recommended substitute parts are ROHS3 compliant, addressing the RoHS non-compliance status of the discontinued B360B-13. For automotive applications, B360B-13-F, B360BQ-13-F, STPS160UY, and STPS3L60UY carry AEC-Q101 qualification.

Frequently Asked Questions (FAQ)

Q: Can B360B-13-F be used as a direct replacement for B360B-13?

A: Yes. B360B-13-F is a direct equivalent with identical electrical specifications: 60V reverse voltage, 3A average rectified current, 700 mV forward voltage at 3A, and fast recovery characteristics. The primary difference is product status (active versus discontinued) and RoHS compliance (ROHS3 versus non-compliant). B360B-13-F is available in Cut Tape and Digi-Reel packaging.

Q: What is the difference between B360B-13-F and B360BQ-13-F?

A: Both parts are electrically identical with the same 60V/3A ratings and specifications. The difference is packaging format: B360B-13-F is supplied in Cut Tape and Digi-Reel, while B360BQ-13-F is supplied in Tape & Reel. Both are active products with ROHS3 compliance and AEC-Q101 qualification.

Q: Can STPS3L60UY replace B360B-13 in all applications?

A: STPS3L60UY maintains the 60V reverse voltage and 3A current rating, making it electrically compatible. However, it offers improved performance characteristics: lower forward voltage (620 mV versus 700 mV at 3A) and lower reverse leakage current (150 µA versus 500 µA). These differences are beneficial in most applications. STPS3L60UY includes AEC-Q101 automotive qualification.

Q: Why are STPS160U and STPS160UY listed as substitutes if they are rated for only 1A?

A: STPS160U and STPS160UY are partial substitutes suitable only for applications where circuit current does not exceed 1A. They maintain the 60V reverse voltage and SMB package compatibility but cannot be used in circuits designed for 3A operation. These parts are not recommended for direct replacement of the B360B-13 in 3A applications.

Q: What packaging options are available for equivalent parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel, Tape & Reel (TR), and standard tape formats. All parts maintain the DO-214AA SMB surface mount package for PCB compatibility. Packaging selection depends on procurement and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The original B360B-13 is RoHS non-compliant. Substitution with any of the listed equivalent parts addresses RoHS compliance requirements.

Q: Which substitute part offers the best performance improvement?

A: STPS3L60U and STPS3L60UY offer measurable performance improvements over the B360B-13: forward voltage is reduced from 700 mV to 620 mV at 3A, and reverse leakage current is reduced from 500 µA to 150 µA at 60V. These characteristics result in lower power dissipation and improved circuit efficiency. STPS3L60UY includes AEC-Q101 automotive qualification.

Q: Can I use SS36B as a substitute?

A: Yes. SS36B is a parametric equivalent with identical electrical specifications to B360B-13: 60V reverse voltage, 3A current rating, 700 mV forward voltage at 3A, and 500 µA reverse leakage. SS36B is ROHS3 compliant and available in active production status with high inventory availability.

Q: What is the difference between CDBB360-G and CMSH3-60M TR13 PBFREE?

A: Both parts maintain 60V/3A ratings and SMB packaging. CMSH3-60M TR13 PBFREE has slightly higher forward voltage (750 mV versus 700 mV at 3A) and higher capacitance (280 pF versus unspecified for CDBB360-G). CDBB360-G is the preferred choice when forward voltage characteristics are critical.

Q: Is automotive qualification required for my application?

A: Automotive qualification (AEC-Q101) is required only for automotive applications. For general industrial and consumer applications, non-qualified parts are acceptable. If automotive qualification is required, select B360B-13-F, B360BQ-13-F, STPS160UY, or STPS3L60UY.
