1N5407 Equivalent & Substitute Parts

Part Overview

The 1N5407 is a general-purpose rectifier diode rated for 800 V DC reverse voltage and 3 A average rectified current in a through-hole axial package. Manufactured by onsemi, this component is classified as obsolete and is no longer recommended for new designs. The 1N5407 operates across a junction temperature range of −65°C to 170°C with standard recovery characteristics exceeding 500 ns at currents greater than 200 mA.

Due to its obsolete status and RoHS non-compliance, direct replacement with active, RoHS-compliant alternatives is necessary for new applications and ongoing production requirements. Equivalent substitute parts maintain the same electrical ratings while offering improved availability, compliance certifications, and active product support from current manufacturers.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 1N5407 with any of the listed substitute parts?

A: Yes, all listed substitute parts maintain the core electrical specifications of 800 V reverse voltage, 3 A average rectified current, and standard recovery characteristics. They are mechanically compatible with through-hole axial mounting. However, verify that your application's operating temperature range falls within the substitute part's specified junction temperature limits.

Q: What is the difference between DO-201AA, DO-27, and DO-201AD packages?

A: DO-201AA and DO-27 are equivalent designations for the same axial through-hole package used in the original 1N5407. DO-201AD is a variant of the same package family. All three are mechanically compatible for through-hole mounting on printed circuit boards. Consult component datasheets for precise dimensional specifications if board layout is critical.

Q: Why do some substitute parts have lower forward voltage (Vf) specifications?

A: Forward voltage variation within the 1.0 V to 1.7 V range is normal across different manufacturers and process technologies. Lower forward voltage (1.0 V to 1.1 V) results in reduced power dissipation and heat generation. Higher forward voltage (1.2 V to 1.7 V) may occur in fast-recovery variants. Select based on your circuit's power budget and thermal management requirements.

Q: Is RoHS compliance mandatory for my application?

A: RoHS3 compliance is required for products sold in the European Union and many other regulated markets. All recommended substitute parts are ROHS3 compliant. If your application is not subject to RoHS regulations, the original 1N5407 specifications remain valid, but active product availability is limited due to obsolescence.

Q: What is the significance of reverse leakage current differences (5 µA vs. 10 µA)?

A: Reverse leakage current affects circuit performance in high-impedance applications and at elevated temperatures. The original 1N5407 specifies 10 µA @ 800 V. Most substitute parts specify 5 µA @ 800 V, representing improved leakage characteristics. This difference is negligible in most power rectification applications but beneficial in precision analog circuits.

Q: Can I use the EGP30K with its fast recovery characteristics as a direct replacement?

A: The EGP30K is electrically compatible with the 1N5407 for voltage and current ratings. However, its fast recovery characteristic (≤500 ns) differs from the standard recovery (>500 ns) of the original part. Fast recovery reduces switching losses and is generally beneficial in rectifier applications. Verify that your circuit design does not depend on the slower recovery time of the original 1N5407.

Q: Which substitute part has the best availability?

A: The 1N5407-E3/54 (Vishay) has the highest inventory with 5,985 units in stock, followed by EGP30K (Fairchild) with 5,092 units and 1N5407G (Taiwan Semiconductor) with 4,462 units. Inventory levels are subject to change; consult current stock status with your supplier.

Q: Are there packaging format differences I should consider?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Tape & Reel (TR), Tape & Box (TB), and Bulk. These formats affect handling, storage, and automated assembly compatibility. Through-hole axial components are typically supplied in tape or bulk formats. Verify packaging compatibility with your assembly process.

Q: What is the operating temperature range I should select?

A: The original 1N5407 operates from −65°C to 170°C. Most substitute parts operate from −55°C to −65°C (lower bound) and 125°C to 150°C (upper bound). If your application requires the full −65°C to 170°C range, select 1N5407-B, 1N5407G-T, or 1N5407-G. For standard industrial applications (−40°C to 85°C ambient), all listed substitutes are suitable.
