Engineering Selection Recommendations

For Direct Current Rating Replacement (4 A):

MUR460RLG (onsemi) is the primary equivalent substitute. It maintains identical electrical specifications (600 V, 4 A, 1.28 V forward voltage at 4 A) with fast recovery characteristics (75 ns trr). The part is Active status and ROHS3 compliant. Package compatibility includes DO-201AA, DO-27, and axial configurations, providing mechanical flexibility. Operating temperature range extends to 175°C maximum junction temperature, exceeding the original specification.

For Reduced Current Applications (3 A to 3.5 A):

When circuit requirements permit lower current ratings, the following parts are suitable:

STTH3L06 (STMicroelectronics): Active status, fast recovery (85 ns trr), 600 V rating, 3 A current, DO-201AD package. Forward voltage of 1.3 V @ 3 A and reverse leakage of 3 µA @ 600 V provide efficient operation. ROHS3 compliant.
31GF6-E3/54 (Vishay General Semiconductor - Diodes Division): Active status, fast recovery (30 ns trr), 600 V rating, 3 A current, DO-201AD package. Lowest reverse recovery time in the 3 A category. ROHS3 compliant.
1N5406-E3/54 (Vishay General Semiconductor - Diodes Division): Active status, 600 V rating, 3 A current, DO-201AD package. Standard recovery characteristics (>500 ns). Forward voltage of 1.2 V @ 3 A. ROHS3 compliant.
MR856G (onsemi): Active status, fast recovery (300 ns trr), 600 V rating, 3 A current. Axial package configuration. ROHS3 compliant.

For Alternative Package Configurations:

BYV28-600-TAP (Vishay General Semiconductor - Diodes Division) offers avalanche technology with 600 V, 3.5 A rating in SOD-64 package. Fast recovery characteristics (210 ns trr) and extended temperature range to 175°C. Suitable when SOD-64 package is preferred over axial configuration. ROHS3 compliant.

Parts to Avoid for New Designs:

1N5406RLG (onsemi) and EGP30J (onsemi) carry "Not For New Designs" status and should not be selected for new circuit implementations, despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can MUR460RLG directly replace MUR460GP-TP?

A: Yes. MUR460RLG provides identical electrical specifications (600 V, 4 A, 1.28 V forward voltage, fast recovery) with equivalent or superior performance. Both are ROHS3 compliant and rated for -55°C to 150°C minimum operating range. MUR460RLG extends to 175°C maximum junction temperature. Axial package compatibility is maintained.

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

A: Fast recovery diodes have reverse recovery time (trr) ≤ 500 ns, while standard recovery diodes exceed 500 ns. MUR460GP-TP is fast recovery (60 ns trr), suitable for switching power supplies. Standard recovery parts like 1N5406-E3/54 (>500 ns) are acceptable for lower-frequency rectification but generate more switching noise in high-frequency applications.

Q: Can I use a 3 A rated diode in place of the 4 A MUR460GP-TP?

A: Substitution is possible only if circuit analysis confirms that maximum current demand does not exceed 3 A. Parts like STTH3L06, 31GF6-E3/54, and 1N5406-E3/54 maintain 600 V voltage rating and DO-201AD package compatibility. Forward voltage and reverse recovery characteristics differ; verify thermal and switching performance for the specific application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting environmental and regulatory requirements equivalent to MUR460GP-TP.

Q: What is the significance of reverse recovery time (trr)?

A: Reverse recovery time determines switching speed and energy loss during diode turn-off. Lower trr values (MUR460GP-TP at 60 ns, 31GF6-E3/54 at 30 ns) reduce switching losses and electromagnetic interference in high-frequency circuits. Higher trr values (MR856G at 300 ns) are acceptable in lower-frequency applications but increase power dissipation.

Q: Does package type affect electrical performance?

A: Package type (DO-201AD, DO-27, DO-201AA, SOD-64) does not alter electrical specifications but affects mechanical mounting and thermal characteristics. All listed packages are axial through-hole configurations suitable for PCB insertion. SOD-64 (BYV28-600-TAP) provides compact form factor with equivalent electrical performance.

Q: Why are some parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status (1N5406RLG, EGP30J) remain available for legacy system support and repair but are not recommended for new circuit development. Active status parts should be prioritized for new designs to ensure long-term supply availability and manufacturer support.

Q: What is the operating temperature range consideration?

A: MUR460GP-TP operates from -55°C to 150°C junction temperature. Most substitutes maintain this range or extend it. MUR460RLG extends to 175°C, providing thermal margin. Verify application requirements; if circuits operate near temperature limits, select parts with extended ranges.

Q: How do forward voltage differences affect circuit design?

A: Forward voltage (Vf) varies between 1.0 V and 1.7 V across substitutes at their respective current ratings. Higher Vf increases power dissipation and heat generation. For 4 A applications, MUR460GP-TP and MUR460RLG both specify 1.28 V @ 4 A. For 3 A applications, 1N5406-G offers lowest Vf (1.0 V), reducing losses.
