Voltage - Forward (Vf) (Max) @ If: Must not exceed 1.15 V at rated current
Speed: Must maintain Standard Recovery >500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: Must not exceed 10 µA @ 100 V

Mechanical Compatibility Requirements:

Package / Case: Must be DO-214AB, SMC

Substitute parts are grouped into two categories:

Category 1 - Direct Electrical Equivalent (100 V, 5 A): Parts that maintain identical electrical ratings and current capacity, ensuring drop-in replacement capability.

Category 2 - Electrical Substitute with Reduced Current Rating (100 V, 3 A): Parts that maintain voltage rating but operate at reduced current capacity. These are suitable only for applications where the actual operating current does not exceed the substitute part's rating.

Engineering Selection Recommendations

S5BC-13-F (Diodes Incorporated)

This part is the primary substitute for the S5BC-13. It maintains identical electrical specifications (100 V, 5 A) and package configuration. The S5BC-13-F is currently active in production with ROHS3 compliance, addressing the RoHS non-compliance status of the discontinued S5BC-13. Operating temperature range is -65°C ~ 150°C, matching the original part. This substitute provides direct compatibility for all applications previously using the S5BC-13.

S5BHE3_A/H (Vishay General Semiconductor - Diodes Division)

This part maintains identical electrical specifications (100 V, 5 A) and package configuration as the S5BC-13. The S5BHE3_A/H is currently active in production with ROHS3 compliance and AEC-Q101 automotive qualification. Operating temperature range is -55°C ~ 150°C. This substitute is suitable for applications where the lower minimum operating temperature of -55°C is acceptable. The automotive qualification provides additional reliability assurance for demanding applications.

ACGRC302-HF (Comchip Technology)

This part operates at 100 V reverse voltage but with a reduced current rating of 3 A, compared to the 5 A rating of the S5BC-13. The ACGRC302-HF is currently active in production with ROHS3 compliance and AEC-Q101 automotive qualification. This substitute is applicable only to applications where the actual operating current does not exceed 3 A. The reduced reverse leakage current (5 µA versus 10 µA) and lower capacitance (20pF versus 40pF) may provide performance benefits in specific circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can the S5BC-13-F be used as a direct replacement for the S5BC-13?

A: Yes. The S5BC-13-F maintains identical electrical specifications (100 V, 5 A) and package configuration (DO-214AB, SMC). Both parts share the same base product number (S5B) and are manufactured by Diodes Incorporated. The primary difference is product status and RoHS compliance, with S5BC-13-F being active and ROHS3 compliant.

Q: What is the difference between the S5BC-13 and S5BHE3_A/H?

A: Both parts share identical electrical specifications (100 V, 5 A) and package configuration (DO-214AB, SMC). The S5BHE3_A/H is manufactured by Vishay and includes AEC-Q101 automotive qualification. The operating temperature range differs: S5BC-13 operates from -65°C to 150°C, while S5BHE3_A/H operates from -55°C to 150°C. The S5BHE3_A/H is currently active in production with ROHS3 compliance.

Q: Can the ACGRC302-HF replace the S5BC-13 in all applications?

A: The ACGRC302-HF is suitable only for applications where the actual operating current does not exceed 3 A. While it maintains the 100 V reverse voltage rating and DO-214AB package configuration, its 3 A current rating is lower than the S5BC-13's 5 A rating. Applications requiring the full 5 A capacity must use S5BC-13-F or S5BHE3_A/H.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: The S5BC-13 is RoHS non-compliant, while all substitute parts (S5BC-13-F, ACGRC302-HF, and S5BHE3_A/H) are ROHS3 compliant. For new designs or production runs subject to RoHS regulations, a compliant substitute is required. For legacy systems not subject to RoHS requirements, compliance status does not affect electrical functionality.

Q: Are there temperature range considerations when selecting a substitute?

A: The S5BC-13 operates from -65°C to 150°C. The S5BC-13-F maintains this range. Both ACGRC302-HF and S5BHE3_A/H operate from -55°C to 150°C, with a higher minimum temperature. For applications requiring operation below -55°C, only S5BC-13 or S5BC-13-F are suitable.

Q: What does AEC-Q101 qualification indicate?

A: AEC-Q101 is an automotive qualification standard. Both ACGRC302-HF and S5BHE3_A/H carry this qualification, indicating they meet automotive industry reliability and performance requirements. This qualification is not present on the S5BC-13 or S5BC-13-F.

Q: How do reverse leakage current differences affect circuit performance?

A: The S5BC-13, S5BC-13-F, and S5BHE3_A/H all specify 10 µA reverse leakage at 100 V. The ACGRC302-HF specifies 5 µA reverse leakage at 100 V. Lower reverse leakage current reduces power dissipation and may improve performance in high-impedance circuits. For most general-purpose applications, this difference is not significant.

Q: What packaging options are available for these substitute parts?

A: All substitute parts use the DO-214AB (SMC) surface mount package, matching the S5BC-13. S5BC-13-F is available in Cut Tape (CT) and Digi-Reel packaging. ACGRC302-HF and S5BHE3_A/H are available in Tape & Reel (TR) packaging. Packaging format does not affect electrical or mechanical compatibility.
