Engineering Selection Recommendations

1N5404-E3/73 (Vishay General Semiconductor - Diodes Division)

This part is a direct electrical equivalent with Active product status. All critical parameters match the 1N5404GP-TP specification. The forward voltage is 0.1 V higher (1.2 V vs. 1.1 V), which remains within acceptable tolerance for general-purpose rectification. The operating temperature range is -50°C to 150°C, which covers the upper portion of the 1N5404GP-TP range. This part is recommended for new designs and ongoing production requiring 400 V, 3 A rectification in DO-201AD packaging.

1N5404RLG (onsemi)

This part meets all critical electrical parameters with a lower forward voltage (1.0 V @ 3 A). The package designation is DO-201AA/DO-27, which is mechanically compatible with DO-201AD axial through-hole applications. The operating temperature range extends to -65°C, providing broader low-temperature coverage. However, this part carries "Not For New Designs" status. Reverse leakage is specified at 10 µA, which is acceptable but higher than the main part. This part is suitable for legacy system replacement where existing inventory or supply chain constraints apply.

SF36GHA0G (Taiwan Semiconductor Corporation)

This part provides Active product status with all critical parameters met. It features Fast Recovery characteristics (≤500ns, 35 ns reverse recovery time), which differs from the Standard Recovery specification of the main part. The forward voltage is 1.3 V @ 3 A, representing the upper tolerance limit. This part includes AEC-Q101 automotive qualification and is suitable for applications requiring enhanced switching performance or automotive-grade reliability. The higher capacitance (60 pF) should be evaluated in high-frequency applications.

BY252P-E3/54 (Vishay General Semiconductor - Diodes Division)

This part is a parametric equivalent with Active product status. All critical parameters match the 1N5404GP-TP specification exactly, including forward voltage (1.1 V @ 3 A), reverse leakage (5 µA), and capacitance (40 pF). The operating temperature range is -55°C to 150°C, identical to the main part. This part is recommended as a direct replacement for applications requiring identical electrical characteristics and is suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use 1N5404-E3/73 as a direct replacement for 1N5404GP-TP?

A: Yes. The 1N5404-E3/73 meets all critical electrical parameters: 400 V reverse voltage, 3 A average rectified current, DO-201AD axial package, and through-hole mounting. The forward voltage difference of 0.1 V (1.2 V vs. 1.1 V) is within acceptable tolerance for general-purpose rectification. The 1N5404-E3/73 has Active product status, making it suitable for new designs.

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

A: Standard Recovery (>500ns) indicates slower switching characteristics, typical for general-purpose rectification in power supplies and linear applications. Fast Recovery (≤500ns) provides faster switching, beneficial in high-frequency switching applications. The SF36GHA0G offers Fast Recovery with 35 ns reverse recovery time, while other substitutes maintain Standard Recovery. Selection depends on application switching frequency requirements.

Q: Is the 1N5404RLG suitable for new designs?

A: The 1N5404RLG carries "Not For New Designs" status from onsemi. While it meets all critical electrical parameters and is mechanically compatible, it is intended for legacy system support and replacement applications. For new designs, use 1N5404-E3/73, SF36GHA0G, or BY252P-E3/54, which all have Active product status.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts are available in axial through-hole configuration. The 1N5404-E3/73, SF36GHA0G, and BY252P-E3/54 are specified in DO-201AD packaging, identical to the main part. The 1N5404RLG is specified as DO-201AA/DO-27, which is mechanically compatible with DO-201AD for through-hole PCB applications but represents a slightly different package designation.

Q: What is the significance of RoHS3 compliance?

A: All listed parts, including the main part and substitutes, are ROHS3 Compliant. This certification confirms that the parts do not contain restricted substances (lead, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, and bis(2-ethylhexyl) phthalate) above specified thresholds. ROHS3 compliance is required for products sold in the European Union and is increasingly required globally.

Q: Can I use SF36GHA0G in applications where the original 1N5404GP-TP was used?

A: Yes, with consideration of the Fast Recovery characteristic. The SF36GHA0G meets all critical electrical parameters and is mechanically compatible. The Fast Recovery specification (35 ns reverse recovery time) provides faster switching than the Standard Recovery of the original part. In linear power supply applications, this difference is negligible. In switching applications, the faster recovery may improve efficiency. The AEC-Q101 automotive qualification makes this part suitable for automotive and industrial applications.

Q: What does "Not For New Designs" mean for the 1N5404GP-TP?

A: "Not For New Designs" indicates that Micro Commercial Co has discontinued active development and promotion of this part number. While existing inventory may be available, the manufacturer recommends using alternative part numbers for new product designs. This status is common for legacy components that have been superseded by improved versions or alternative manufacturers' offerings.

Q: Are there temperature range differences between substitutes?

A: Yes. The 1N5404GP-TP and BY252P-E3/54 operate from -55°C to 150°C. The 1N5404-E3/73 operates from -50°C to 150°C, providing slightly reduced low-temperature coverage. The 1N5404RLG operates from -65°C to 150°C, providing extended low-temperature capability. For applications requiring operation below -55°C, the 1N5404RLG is required. For standard industrial applications, all parts are acceptable.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume or manual assembly. Both formats contain the same component in the same package. Selection depends on assembly process requirements and order volume.
