S5KBHR5G Equivalent & Substitute Parts

Part Overview

The S5KBHR5G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V DC reverse voltage and 5 A average rectified current in a DO-214AA (SMB) surface mount package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs. Substitute parts are selected based on matching or compatible electrical characteristics and package specifications.

Substitute Part Grouping Explanation

Substitute parts for the S5KBHR5G are categorized based on the following substitution criteria:

Parametric Equivalent (Direct Replacement): Parts matching all critical electrical parameters: 800 V reverse voltage, 5 A average rectified current, fast recovery speed (≤ 500ns), DO-214AA package, and compatible operating temperature range. These parts are functionally interchangeable with the main part.

Similar Parts (Reduced Current Rating): Parts with 800 V reverse voltage and DO-214AA package but reduced average rectified current (1.5 A or 2 A). These parts operate within the same voltage class and package form factor but are suitable only for applications requiring lower current capacity.

Similar Parts (Alternate Package): Parts with 800 V reverse voltage and reduced current rating but in alternative surface mount packages (SMA instead of SMB). These require PCB layout modification and are not direct mechanical substitutes.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 800 V (required match)
Package / Case: DO-214AA, SMB (required for direct mechanical substitution)
Current - Average Rectified (Io): 5 A (required for full electrical equivalence)
Speed: Fast Recovery ≤ 500ns (required for parametric equivalence)

Engineering Selection Recommendations

Parametric Equivalent: The S5KB R5G (Taiwan Semiconductor Corporation) is the direct parametric equivalent to the S5KBHR5G, matching all electrical specifications and package requirements. Both parts are discontinued at DiGi Electronics but maintain identical performance characteristics. This part should be selected when full electrical equivalence is required.

Active Alternatives for Reduced Current Applications: For applications where the full 5 A current capacity is not required, the following active parts provide equivalent voltage ratings and package compatibility:

CURB206-G (Comchip Technology): 2 A rated current, fast recovery speed, active product status. Suitable for circuits requiring up to 2 A average rectified current.
RS2K-13-F, RS2KHE3_A/H, RS2KHE3_A/I (Diodes Incorporated / Vishay): 1.5 A rated current, fast recovery speed, active product status. RS2KHE3_A/H and RS2KHE3_A/I include automotive-grade qualification (AEC-Q101).
S2K-13-F, S2KHE3_A/H (Diodes Incorporated / Vishay): 1.5 A rated current, standard recovery speed, active product status. S2KHE3_A/H includes automotive-grade qualification (AEC-Q101).

Package Considerations: Parts designated with "A" suffix (RS2KA-13-F, S2KA-13-F) use DO-214AC (SMA) package instead of DO-214AA (SMB). These require PCB layout modification and are not direct mechanical substitutes.

Compliance Status: All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, consistent with the main part specifications.

Frequently Asked Questions (FAQ)

Q: Can S5KB R5G be used as a direct replacement for S5KBHR5G? A: Yes. The S5KB R5G is a parametric equivalent with identical electrical specifications (800 V, 5 A, fast recovery ≤ 500ns) and DO-214AA package. Both parts are discontinued at DiGi Electronics but are functionally interchangeable.

Q: What is the difference between fast recovery and standard recovery speed classifications? A: Fast recovery diodes have reverse recovery time ≤ 500ns, while standard recovery diodes exceed 500ns. The S5KBHR5G specifies fast recovery. Substitute parts with standard recovery (S2K, S2K-13-F, S2KHE3_A/H) have longer reverse recovery times and may not be suitable for high-frequency switching applications.

Q: Can I use a 1.5 A rated diode in place of the 5 A S5KBHR5G? A: Only if the application circuit requires less than 1.5 A average rectified current. Using an undersized diode in a 5 A application will cause excessive junction temperature and premature failure. Current rating must match or exceed circuit requirements.

Q: What is the significance of the DO-214AA versus DO-214AC package designation? A: DO-214AA (SMB) and DO-214AC (SMA) are different surface mount packages with different footprints. Parts with SMA package (RS2KA-13-F, S2KA-13-F) require different PCB land patterns and are not mechanically interchangeable with SMB packages.

Q: Are automotive-qualified parts (AEC-Q101) required for this application? A: Automotive qualification is not required unless the application is automotive-grade. RS2KHE3_A/H, RS2KHE3_A/I, and S2KHE3_A/H carry AEC-Q101 qualification and are suitable for automotive environments but are not necessary for general-purpose applications.

Q: What is the operating temperature range difference between substitute parts? A: The S5KBHR5G operates from -55°C to 150°C. Some substitutes (RS2K-13-F, S2K-13-F, S2KA-13-F) extend the lower limit to -65°C. This wider range does not affect compatibility in applications within the -55°C to 150°C window.

Q: Can I use CURB206-G (2 A) instead of S5KBHR5G (5 A)? A: Only if the application requires maximum 2 A average rectified current. CURB206-G maintains the same 800 V voltage rating and DO-214AA package but has reduced current capacity. Verify circuit current requirements before substitution.
