Engineering Selection Recommendations

Standard Recovery Substitutes (1N5407-E3/54, 1N5407-E3/73): These parts maintain Standard Recovery characteristics identical to the 1N5407G A0G and are manufactured by Vishay General Semiconductor. Both are ROHS3 compliant and Active product status. Forward voltage is elevated to 1.2 V at 3 A compared to the main part specification of 1.0 V. Operating temperature range is -50°C to 150°C, with the lower bound 5°C higher than the main part. These substitutes are suitable for applications where recovery speed characteristics must remain unchanged and forward voltage elevation is acceptable.

Fast Recovery Substitutes (UF5407-E3/54, UF5407-E3/73, EGP30K): These parts feature Fast Recovery characteristics (≤500 ns) and are suitable for applications requiring improved switching performance. UF5407-E3/54 and UF5407-E3/73 are manufactured by Vishay General Semiconductor and are ROHS3 compliant with Active product status. Forward voltage is 1.7 V at 3 A. Reverse leakage current is elevated to 10 µA at 800 V. EGP30K is manufactured by Fairchild Semiconductor with Active product status and extended operating temperature range (-65°C to 150°C). RoHS status for EGP30K is not specified in available data. Fast Recovery substitutes are suitable for switching applications and power supply circuits where recovery time performance is a design requirement.

Compliance Considerations: All substitute parts maintain 800 V / 3 A electrical ratings and DO-201AD axial through-hole packaging. ROHS3 compliance is confirmed for 1N5407-E3/54, 1N5407-E3/73, UF5407-E3/54, and UF5407-E3/73. All parts are classified as Active product status. REACH Unaffected status is confirmed for all Vishay parts.

Frequently Asked Questions (FAQ)

Q: Can 1N5407-E3/54 and 1N5407-E3/73 be used interchangeably with 1N5407G A0G?

A: Yes, within the constraints of forward voltage tolerance. Both parts are Standard Recovery diodes with identical 800 V / 3 A ratings and DO-201AD packaging. Forward voltage is 1.2 V at 3 A compared to 1.0 V for the main part. The 0.2 V increase must be evaluated against circuit design margins. Operating temperature range is -50°C to 150°C versus -55°C to 150°C for the main part.

Q: What is the difference between Standard Recovery and Fast Recovery substitutes?

A: Standard Recovery substitutes (1N5407-E3/54, 1N5407-E3/73) maintain recovery time >500 ns, matching the main part specification. Fast Recovery substitutes (UF5407-E3/54, UF5407-E3/73, EGP30K) feature recovery time ≤500 ns with reverse recovery time of 75 ns. Fast Recovery diodes are used in switching applications and power supplies where reduced switching losses are required. Forward voltage is higher at 1.7 V for Fast Recovery types.

Q: Are all substitute parts ROHS3 compliant?

A: ROHS3 compliance is confirmed for 1N5407-E3/54, 1N5407-E3/73, UF5407-E3/54, and UF5407-E3/73. EGP30K RoHS status is not specified in available technical data.

Q: Can Fast Recovery diodes replace Standard Recovery diodes in any application?

A: Fast Recovery diodes are electrically compatible for 800 V / 3 A applications and can be used in Standard Recovery circuits. However, the higher forward voltage (1.7 V versus 1.0 V) and increased reverse leakage current (10 µA versus 5 µA) must be evaluated against circuit design specifications. Fast Recovery diodes are optimized for switching applications and may introduce different thermal characteristics in linear rectification circuits.

Q: What is the significance of the packaging designation (CT versus Bulk)?

A: CT (Cut Tape) packaging indicates individual components on continuous tape suitable for automated assembly. Bulk packaging indicates loose components. All substitute parts maintain DO-201AD axial through-hole form factor and are mechanically compatible. Packaging format selection depends on assembly process requirements and inventory management practices.

Q: Are there temperature range differences between substitute parts?

A: Yes. The main part 1N5407G A0G operates from -55°C to 150°C. Standard Recovery substitutes (1N5407-E3/54, 1N5407-E3/73) operate from -50°C to 150°C, with a 5°C higher lower bound. Fast Recovery substitutes UF5407-E3/54 and UF5407-E3/73 operate from -55°C to 150°C, matching the main part. EGP30K operates from -65°C to 150°C with extended low-temperature capability. Temperature range selection depends on application environment specifications.

Q: What is the reverse leakage current difference between substitute parts?

A: The main part and Standard Recovery substitutes specify 5 µA reverse leakage at 800 V. Fast Recovery substitutes UF5407-E3/54 and UF5407-E3/73 specify 10 µA at 800 V, representing a 2× increase. EGP30K specifies 5 µA at 800 V. Higher reverse leakage may affect circuit performance in high-impedance applications and must be evaluated against design requirements.
