SF67G A0G Equivalent & Substitute Parts

Part Overview

The SF67G A0G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 500 V DC reverse voltage and 6 A average rectified current. The device features fast recovery characteristics with a reverse recovery time of 35 ns and is packaged in the DO-201AD axial through-hole configuration. This diode is classified as Active product status and is RoHS3 compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SF67G A0G is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain the same maximum DC reverse voltage rating of 500 V to ensure equivalent circuit protection and voltage withstand capability.

Package and Mounting: The substitute part must use the DO-201AD axial through-hole package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Regulatory Compliance: The substitute part must maintain RoHS3 compliance and REACH unaffected status to satisfy environmental and regulatory requirements.

Current Rating Consideration: While the SF67G A0G is rated for 6 A average rectified current, substitute parts with lower current ratings (such as 3 A) may be used in applications where the circuit design does not require the full 6 A capacity, provided all other electrical parameters remain compatible.

The identified substitute part 1N5405-E3/54 meets the voltage rating, package, and compliance requirements. However, the current rating differs at 3 A versus 6 A, which restricts its use to circuits designed for lower current operation.

Engineering Selection Recommendations

Primary Part (SF67G A0G): This diode is the preferred selection for applications requiring 6 A average rectified current at 500 V reverse voltage with fast recovery characteristics. The part is Active status, RoHS3 compliant, and maintains full regulatory compliance. Use this part when circuit design specifications call for 6 A current capacity and fast recovery performance.

Substitute Part (1N5405-E3/54): This Vishay diode is suitable for applications where the circuit design operates at 3 A or lower average rectified current. The part maintains the same 500 V voltage rating and DO-201AD package compatibility. Both parts are Active status and RoHS3 compliant. The 1N5405-E3/54 operates with standard recovery characteristics rather than fast recovery, and the lower current rating restricts its use to circuits designed for reduced current operation. The operating temperature range is -50°C to 150°C, which is narrower than the SF67G A0G at -55°C to 150°C.

Selection between these parts depends on circuit current requirements and recovery speed specifications. Do not substitute the 1N5405-E3/54 in circuits designed for the full 6 A capacity of the SF67G A0G.

Frequently Asked Questions (FAQ)

Q: Can the 1N5405-E3/54 be used as a direct replacement for the SF67G A0G?

A: The 1N5405-E3/54 is mechanically compatible (same DO-201AD package) and electrically compatible for voltage rating (500 V). However, the current rating differs: 1N5405-E3/54 is rated for 3 A while SF67G A0G is rated for 6 A. Substitution is only valid if the circuit design operates at 3 A or lower. Do not use this substitute in circuits requiring 6 A operation.

Q: What is the difference between fast recovery and standard recovery in these diodes?

A: The SF67G A0G features fast recovery with a reverse recovery time of 35 ns, while the 1N5405-E3/54 uses standard recovery with recovery time exceeding 500 ns. Fast recovery diodes switch more quickly, reducing switching losses in high-frequency applications. Standard recovery diodes are suitable for lower-frequency rectification circuits.

Q: Are both parts RoHS3 compliant?

A: Yes, both the SF67G A0G and 1N5405-E3/54 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for each part?

A: The SF67G A0G operates from -55°C to 150°C junction temperature. The 1N5405-E3/54 operates from -50°C to 150°C. The SF67G A0G has a wider low-temperature range by 5°C.

Q: Can I use the SF67G A0G in a circuit designed for the 1N5405-E3/54?

A: Yes, the SF67G A0G can be used in circuits designed for the 1N5405-E3/54 because it provides higher current capacity (6 A versus 3 A) and faster recovery characteristics. The 500 V voltage rating and DO-201AD package are identical. This represents an upgrade path for circuits requiring improved performance.

Q: What packaging options are available for these parts?

A: Both parts use the DO-201AD axial through-hole package. The SF67G A0G is supplied in standard packaging, while the 1N5405-E3/54 is available in Cut Tape (CT) and Tape & Reel (TR) packaging options.

Q: Are there any temperature-related restrictions when substituting these parts?

A: The 1N5405-E3/54 has a minimum operating temperature of -50°C, which is 5°C higher than the SF67G A0G at -55°C. If your application requires operation below -50°C, the SF67G A0G must be used.
