Engineering Selection Recommendations

Direct 5 A Equivalent:

CGRC507-G from Comchip Technology is the only active substitute maintaining the 5 A current rating. This part is electrically compatible with the HS5M M6G, sharing identical 1000 V reverse voltage rating and DO-214AB package. The CGRC507-G exhibits lower forward voltage (1.15 V @ 5 A versus 1.7 V @ 5 A) and standard recovery speed characteristics. This part is ROHS3 compliant and currently in active production status.

3 A Alternatives for Reduced Current Applications:

For applications where 3 A average rectified current is sufficient, multiple active alternatives are available:

ER3M-TP (Micro Commercial Co): Maintains fast recovery characteristics (75 ns) matching the original HS5M M6G speed classification. Operating temperature range extends to 175°C maximum junction temperature.
CURC307-G (Comchip Technology): Fast recovery diode with 75 ns reverse recovery time and identical forward voltage characteristics to the HS5M M6G at rated current.
RS3M-13-F (Diodes Incorporated): Fast recovery classification with extended operating temperature range (-65°C to 150°C). Offers lower forward voltage (1.3 V @ 3 A).
S3M-13-F (Diodes Incorporated): Standard recovery speed with lower forward voltage (1.15 V @ 3 A). Extended operating temperature range (-65°C to 150°C).
S3M-TP (Micro Commercial Co): Standard recovery speed with highest inventory availability (321,300 pieces). Operating temperature range -55°C to 150°C.
S3MHE3_A/H and S3MHE3_A/I (Vishay): Automotive-grade alternatives with AEC-Q101 qualification. Standard recovery speed with extended reverse recovery time (2.5 µs).

Package Variant Considerations:

RS3MB-13-F and S3MB-13-F are available in DO-214AA (SMB) package variant. These parts are mechanically and thermally compatible with SMB footprints but require PCB layout modification from the original DO-214AB (SMC) design.

All listed substitutes maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CGRC507-G directly replace HS5M M6G in all applications?

A: CGRC507-G is electrically compatible with HS5M M6G, maintaining identical 1000 V reverse voltage and 5 A current ratings in the same DO-214AB package. The primary difference is recovery speed classification: CGRC507-G operates at standard recovery (> 500ns) while HS5M M6G is fast recovery (≤ 500ns). Applications operating at high switching frequencies may require evaluation of this parameter.

Q: Why are 3 A alternatives listed for a 5 A part?

A: The HS5M M6G is rated for 5 A, but many circuit designs operate at lower current levels. For applications requiring 3 A or less, the 3 A rated alternatives provide equivalent functionality with potentially improved performance characteristics (lower forward voltage, better availability, active production status).

Q: What is the difference between DO-214AB (SMC) and DO-214AA (SMB) packages?

A: Both are surface mount packages for rectifier diodes. DO-214AB (SMC) is the original package for HS5M M6G. DO-214AA (SMB) is a larger variant. Parts RS3MB-13-F and S3MB-13-F use SMB packaging and require PCB footprint modification. Thermal and electrical performance remain equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the environmental compliance of the original HS5M M6G.

Q: What does "fast recovery" versus "standard recovery" mean for diode selection?

A: Recovery speed refers to reverse recovery time (trr), the time required for a diode to stop conducting when reverse bias is applied. Fast recovery (≤ 500ns) is required for high-frequency switching applications. Standard recovery (> 500ns) is suitable for lower-frequency rectification. The HS5M M6G specifies 75 ns fast recovery. Substitutes with standard recovery may not be suitable for high-frequency applications.

Q: Which substitute offers the best forward voltage performance?

A: CGRC507-G exhibits the lowest forward voltage at 1.15 V @ 5 A, compared to 1.7 V @ 5 A for HS5M M6G. Among 3 A alternatives, S3M-13-F and S3MB-13-F offer 1.15 V @ 3 A forward voltage.

Q: Can automotive-grade parts (S3MHE3_A/H, S3MHE3_A/I) be used in non-automotive applications?

A: Yes. Automotive-grade parts with AEC-Q101 qualification meet or exceed standard industrial specifications. These parts are suitable for any application requiring 1000 V, 3 A rectification with standard recovery characteristics.

Q: What is the significance of operating temperature range differences?

A: HS5M M6G specifies -55°C to 150°C junction temperature range. Some alternatives extend to -65°C or 175°C. Extended temperature ranges provide design margin for applications operating in extreme thermal environments. Standard industrial applications typically operate within -55°C to 150°C range.
