Key Parameters

Substitute Part Grouping Explanation

Substitution of the SF15-AP is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 300 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.3 V or lower @ 1 A
• Reverse Recovery Time (trr): 35 ns or faster
• Current - Reverse Leakage @ Vr: 5 µA or lower @ 300 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Package / Case: DO-204AL, DO-41, or Axial configuration
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C minimum to 125°C minimum

The SF15G A0G manufactured by Taiwan Semiconductor Corporation meets all specified electrical and mechanical parameters and is classified as an active product, providing design continuity for the obsolete SF15-AP.

Parameter Comparison

Engineering Selection Recommendations

The SF15G A0G is a direct substitute for the SF15-AP based on electrical and mechanical parameter equivalence. The SF15G A0G is classified as an active product with current manufacturing support, whereas the SF15-AP is obsolete. Both components meet ROHS3 compliance requirements and are suitable for through-hole assembly applications requiring 300 V, 1 A rectification.

The SF15G A0G provides an extended operating temperature range (-55°C to 150°C) compared to the SF15-AP (-55°C to 125°C), offering additional thermal margin in applications operating at elevated junction temperatures. The SF15G A0G is available in active inventory with 918 pieces in stock, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the SF15G A0G be used as a direct replacement for the SF15-AP in existing designs?

A: Yes. The SF15G A0G meets all electrical specifications (300 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage, 35 ns reverse recovery time, 5 µA reverse leakage) and mechanical requirements (DO-41 through-hole package) of the SF15-AP. Both components are ROHS3 compliant.

Q: What is the difference in capacitance between the SF15-AP and SF15G A0G?

A: The SF15-AP has a capacitance of 25 pF @ 4V, 1MHz, while the SF15G A0G has a capacitance of 10 pF @ 4V, 1MHz. This difference does not affect substitution eligibility, as capacitance is not a primary selection criterion for general-purpose rectifier diodes in standard applications.

Q: Are there any temperature-related limitations when substituting the SF15-AP with the SF15G A0G?

A: No. The SF15G A0G operates across -55°C to 150°C, which encompasses the SF15-AP operating range of -55°C to 125°C. The extended upper temperature limit of the SF15G A0G provides additional design margin.

Q: What is the package designation for both parts?

A: Both the SF15-AP and SF15G A0G use the DO-204AL (DO-41) axial through-hole package. The physical form factor and pin configuration are identical, enabling direct board-level substitution.

Q: Why is the SF15-AP classified as obsolete?

A: The SF15-AP is no longer in active production. The SF15G A0G serves as the active equivalent from Taiwan Semiconductor Corporation, providing continued availability and manufacturing support for this rectifier diode specification.
