Primary Substitution Criteria (Exact Match Required):

Voltage - DC Reverse (Vr) (Max): 600 V
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Technology: Standard
RoHS3 Compliance

Secondary Substitution Criteria (Current Rating):

Current - Average Rectified (Io): 5 A (exact match for parametric equivalent)
Current - Average Rectified (Io): ≥ 2 A (acceptable for similar substitutes with lower current ratings, as the S5JBHR5G can be derated)

Performance Parameters (Acceptable Variation):

Engineering Selection Recommendations

Parametric Equivalent Selection:

The S5JB R5G (Taiwan Semiconductor Corporation) is the direct parametric equivalent to the S5JBHR5G. Both parts share identical electrical specifications, current ratings, voltage ratings, and package configuration. The S5JB R5G maintains RoHS3 compliance and REACH unaffected status. This part is recommended as the primary replacement for the discontinued S5JBHR5G where exact electrical performance is required.

Active Substitute Selection for Current-Derated Applications:

When circuit design permits current derating below 5 A, the following active parts are suitable substitutes:

ER3JB-TP (Micro Commercial Co): 3 A rated, 600 V, DO-214AA package, active product status. Suitable for applications requiring 3 A or less. Extended operating temperature range (-50°C to 150°C) matches the S5JBHR5G baseline.
ER2J-LTP (Micro Commercial Co): 2 A rated, 600 V, DO-214AA package, active product status. Extended operating temperature range (-65°C to 175°C) provides broader thermal margin. High inventory availability (28,296 pcs).
MURS160-E3/5BT (Vishay General Semiconductor - Diodes Division): 2 A rated, 600 V, DO-214AA package, active product status. Extended operating temperature range (-65°C to 175°C). Tape & Reel packaging.
CSFB205-G (Comchip Technology): 2 A rated, 600 V, DO-214AA package, active product status. Lowest reverse recovery time (35 ns) among 2 A substitutes. High inventory availability (2,945 pcs).

All recommended substitutes maintain RoHS3 compliance, REACH unaffected status, and fast recovery speed classification. Selection among active substitutes depends on circuit current requirements, thermal operating conditions, and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can the S5JBHR5G be replaced with a lower current-rated part such as the ER2J-LTP (2 A)?

A: Yes, if the circuit design operates at or below 2 A average rectified current. The ER2J-LTP maintains the same 600 V reverse voltage rating and DO-214AA package. However, the circuit must be verified to operate within the 2 A limit. The S5JBHR5G is rated for 5 A, so substitution with lower-rated parts requires confirmation that the application does not demand the full 5 A capacity.

Q: What is the difference between the S5JBHR5G and S5JB R5G?

A: The S5JB R5G is the parametric equivalent of the S5JBHR5G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, current ratings (5 A), voltage ratings (600 V), forward voltage drop (1.1 V @ 5 A), and package configuration (DO-214AA, SMB). Both are discontinued at DiGi Electronics. The primary difference is packaging format: S5JBHR5G is supplied in Cut Tape (CT), while S5JB R5G is available in both Cut Tape (CT) and Digi-Reel® formats.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain RoHS3 compliance and REACH unaffected status, consistent with the S5JBHR5G baseline.

Q: What is the significance of the DO-214AA package designation?

A: DO-214AA, also designated SMB (Surface Mount Body), is the physical package form factor. All listed substitutes use the same DO-214AA package, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes. This package is a standard surface mount rectifier package with identical footprint across all listed parts.

Q: Can I use the MURS160-E3/5BT as a direct replacement for the S5JBHR5G?

A: The MURS160-E3/5BT is a 2 A rated part, whereas the S5JBHR5G is rated for 5 A. Direct replacement is possible only if the circuit operates at 2 A or below. Both parts share the same 600 V reverse voltage rating, DO-214AA package, and fast recovery speed classification. The MURS160-E3/5BT has an extended operating temperature range (-65°C to 175°C) compared to the S5JBHR5G (-55°C to 150°C), providing additional thermal margin in some applications.

Q: What is the difference between fast recovery and standard recovery diodes?

A: All parts in this reference, including the S5JBHR5G and all substitutes, are classified as fast recovery diodes with reverse recovery time ≤ 500 ns for currents > 200 mA. Fast recovery diodes exhibit reduced reverse recovery time, which minimizes switching losses and improves efficiency in high-frequency switching applications compared to standard recovery diodes.

Q: Which substitute offers the lowest forward voltage drop?

A: The MURS160-13-F (Diodes Incorporated) and MURS160-E3/52T (Vishay General Semiconductor - Diodes Division) both specify a forward voltage drop of 1.25 V @ 1 A, which is lower than the S5JBHR5G baseline of 1.1 V @ 5 A. However, forward voltage specifications are current-dependent; direct comparison requires evaluation at the same current level. The S5JBHR5G maintains 1.1 V at its rated 5 A current, which is superior to lower-current-rated substitutes at equivalent current levels.

Q: Is the S5JBHR5G suitable for high-temperature applications?

A: The S5JBHR5G operates across a junction temperature range of -55°C to 150°C. For applications requiring extended high-temperature operation, substitutes such as ER2J-LTP and MURS160-E3/5BT, both rated to 175°C, provide additional thermal margin. Selection depends on specific circuit thermal requirements and derating analysis.
