Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5406GP-TP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 3 A
• Mounting Type: Through Hole
• Package / Case: DO-201AD or DO-201AA/DO-27 Axial configurations

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Substitute parts may vary within the range of 1.0 V to 1.6 V at rated current
• Current - Reverse Leakage @ Vr: Substitute parts may range from 5 µA to 20 µA at 600 V
• Speed: Both Standard Recovery (>500ns) and Fast Recovery (≤500ns) classifications are acceptable
• Operating Temperature - Junction: Substitute parts must support the minimum of -55°C and maximum of 150°C

All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the regulatory status of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The 31GF6-M3/54, GI506-E3/54, and BY253P-E3/54 are all classified as Active products and are suitable for new designs. These parts meet all mandatory electrical parameters and are available in quantities exceeding 5,900 units.

31GF6-M3/54 (Vishay General Semiconductor - Diodes Division): This substitute features Fast Recovery characteristics (≤500ns) compared to the Standard Recovery of the primary part. Forward voltage is elevated at 1.6 V @ 3 A, and reverse leakage current is higher at 20 µA @ 600 V. Operating temperature range is -40°C ~ 150°C. This part is suitable for applications where faster switching performance is beneficial and higher forward voltage drop is acceptable.

GI506-E3/54 (Vishay General Semiconductor - Diodes Division): This substitute maintains Standard Recovery speed characteristics and matches the forward voltage specification of 1.1 V at the primary part's rated current. Reverse leakage current matches at 5 µA @ 600 V. Operating temperature range is -50°C ~ 150°C. This part provides the closest electrical match to the primary component.

BY253P-E3/54 (Vishay General Semiconductor - Diodes Division): This substitute provides identical electrical characteristics to the primary part, including Standard Recovery speed, 1.1 V forward voltage @ 3 A, and 5 µA reverse leakage @ 600 V. Operating temperature range matches at -55°C ~ 150°C. This part is the most direct equivalent.

Secondary Substitute (Not For New Designs):

The 1N5406RLG (onsemi) is classified as Not For New Designs and should be used only for replacement or repair of existing equipment. This part meets all mandatory electrical parameters with slightly lower forward voltage (1.0 V @ 3 A) and higher reverse leakage (10 µA @ 600 V). Operating temperature range extends to -65°C. Package configuration is DO-201AA/DO-27 Axial, which is mechanically compatible with DO-201AD applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1N5406GP-TP with any of the listed parts in new designs?

A: The 31GF6-M3/54, GI506-E3/54, and BY253P-E3/54 are all Active products suitable for new designs. The 1N5406RLG is classified as Not For New Designs and should be reserved for replacement applications only.

Q: What is the difference between DO-201AD and DO-201AA packages?

A: Both are through-hole axial packages with identical electrical performance. The primary part specifies DO-201AD, while the 1N5406RLG is available in DO-201AA/DO-27 configurations. These packages are mechanically compatible for through-hole PCB mounting.

Q: Does the faster recovery speed of the 31GF6-M3/54 affect compatibility?

A: The 31GF6-M3/54 features Fast Recovery (≤500ns) versus Standard Recovery (>500ns) of the primary part. Fast Recovery diodes are suitable for applications where the primary part is specified, as they provide improved switching performance. However, the elevated forward voltage (1.6 V @ 3 A) and higher reverse leakage (20 µA @ 600 V) must be evaluated for the specific application.

Q: Which substitute provides the closest electrical match?

A: The BY253P-E3/54 provides identical electrical specifications to the 1N5406GP-TP, including forward voltage (1.1 V @ 3 A), reverse leakage (5 µA @ 600 V), and operating temperature range (-55°C ~ 150°C).

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory compliance of the primary part.

Q: What is the minimum operating temperature supported by all substitutes?

A: The 31GF6-M3/54 has the highest minimum operating temperature at -40°C. If the application requires operation below -40°C, the GI506-E3/54 (-50°C), 1N5406RLG (-65°C), or BY253P-E3/54 (-55°C) must be selected.

Q: Can I use the 1N5406RLG in existing equipment?

A: Yes, the 1N5406RLG is suitable for replacement and repair of existing equipment. Its Not For New Designs status indicates it is available for legacy applications but should not be selected for new product development.
