Parameter Comparison

Engineering Selection Recommendations

All three diodes maintain Active product status and RoHS3 compliance, qualifying them for equivalent substitution in applications requiring 400 V, 60 A general-purpose rectification with Through Hole TO-247-2 mounting.

FFH60UP40S (onsemi): Primary selection for applications with operating temperature requirements between -65°C and 150°C. Forward voltage drop of 1.3 V @ 60 A and reverse recovery time of 85 ns establish baseline performance characteristics.

DPG60I400HA (IXYS): Suitable for applications requiring extended operating temperature range (-55°C to 175°C) and superior reverse recovery performance (45 ns). Forward voltage drop of 1.47 V @ 60 A results in higher power dissipation compared to the primary part. Reverse leakage current of 1 µA @ 400 V indicates enhanced leakage characteristics.

VS-60EPU04-N3 (Vishay): Suitable for applications requiring extended operating temperature range (-55°C to 175°C). Forward voltage drop of 1.25 V @ 60 A is lower than the primary part, reducing power dissipation. Reverse recovery time of 85 ns matches the primary part. Reverse leakage current of 50 µA @ 400 V is intermediate between the primary and IXYS options.

Frequently Asked Questions (FAQ)

Q: Can DPG60I400HA replace FFH60UP40S in all applications?

A: DPG60I400HA meets the electrical and mechanical substitution criteria of 400 V, 60 A, Through Hole TO-247-2 mounting, and RoHS3 compliance. The forward voltage drop of 1.47 V @ 60 A is higher than the FFH60UP40S (1.3 V @ 60 A), resulting in increased power dissipation. Thermal design must account for this difference. The superior reverse recovery time of 45 ns provides improved switching performance.

Q: What is the difference between TO-247-2 and TO-247AC Modified packages?

A: Both packages are Through Hole mounting types with compatible mechanical footprints. The TO-247AC Modified designation for VS-60EPU04-N3 indicates a variant of the standard TO-247-2 package. Pin configuration and mounting hole spacing remain compatible for direct substitution.

Q: How do forward voltage drops affect circuit performance?

A: Forward voltage drop directly impacts power dissipation in the diode. FFH60UP40S at 1.3 V @ 60 A dissipates 78 W; DPG60I400HA at 1.47 V @ 60 A dissipates 88.2 W; VS-60EPU04-N3 at 1.25 V @ 60 A dissipates 75 W. Thermal management and heat sink design must accommodate the selected part's power dissipation characteristics.

Q: Are all three parts suitable for high-frequency switching applications?

A: All three parts are classified as Fast Recovery diodes with recovery times ≤ 500ns. DPG60I400HA offers the fastest recovery at 45 ns, while FFH60UP40S and VS-60EPU04-N3 both provide 85 ns recovery time. Selection depends on specific switching frequency requirements and circuit topology.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current affects standby power consumption and thermal stability. DPG60I400HA exhibits 1 µA @ 400 V, VS-60EPU04-N3 exhibits 50 µA @ 400 V, and FFH60UP40S exhibits 100 µA @ 400 V. Lower leakage current reduces standby power dissipation and improves performance in high-impedance circuits.

Q: Can these parts be used interchangeably in existing PCB designs?

A: All three parts share Through Hole TO-247-2 package compatibility and identical electrical ratings of 400 V and 60 A. Direct PCB substitution is mechanically feasible. Thermal design review is necessary due to variations in forward voltage drop and reverse leakage current.

Q: What temperature range considerations apply to part selection?

A: FFH60UP40S operates from -65°C to 150°C. DPG60I400HA and VS-60EPU04-N3 both operate from -55°C to 175°C. Applications requiring operation below -55°C must use FFH60UP40S. Applications requiring operation above 150°C must use DPG60I400HA or VS-60EPU04-N3.
