Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS30L30CT is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Voltage - Forward (Vf) (Max) @ If: 460 mV @ 15 A
• Current - Reverse Leakage @ Vr: 1.5 mA @ 30 V
• Operating Temperature - Junction (Max): 150°C

Functional Configuration:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Physical & Mechanical Requirements:

• Mounting Type: Through Hole
• Package / Case: TO-220-3

A substitute part must match all specified electrical ratings, maintain identical diode configuration and technology, and utilize the same through-hole TO-220-3 package to ensure direct compatibility without circuit redesign or PCB modification.

Engineering Selection Recommendations

The STPS30L30CT is classified as an obsolete product. When selecting an equivalent or substitute component, the following engineering criteria apply:

Compliance Considerations:

• The main part carries RoHS non-compliant status. Any substitute must maintain compatibility with existing designs that do not require RoHS compliance.
• REACH Status is listed as REACH Unaffected for the main part. Substitute parts should maintain equivalent regulatory standing.

Regulatory & Classification:

• ECCN classification: EAR99
• HTSUS code: 8541.10.0080

Functional Equivalence: Substitutes must provide identical electrical performance across all specified parameters: 30 V reverse voltage rating, 15 A rectified current capacity, 460 mV forward voltage drop at 15 A, and 1.5 mA reverse leakage current at 30 V. The diode pair common cathode configuration and fast recovery Schottky technology are non-negotiable for circuit operation.

Physical Compatibility: The TO-220-3 through-hole package is mandatory for direct PCB compatibility without layout modification. Pin configuration and thermal characteristics must remain unchanged.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the STPS30L30CT?

A: A valid substitute must match all electrical specifications (30 V reverse voltage, 15 A current rating, 460 mV forward voltage at 15 A, 1.5 mA reverse leakage), maintain the 1 Pair Common Cathode configuration, use Schottky technology with fast recovery characteristics, and be packaged in TO-220-3 through-hole format.

Q: Can I use a different package type as a substitute?

A: No. The TO-220-3 through-hole package is a critical requirement for direct PCB compatibility. Alternative packages would require circuit board redesign and are not considered direct substitutes.

Q: Does the obsolete status affect substitute selection?

A: The obsolete status indicates the part is no longer in active production. Substitute selection must focus on finding equivalent parts with identical electrical and mechanical specifications to maintain design integrity and functionality.

Q: Are there compliance implications when selecting a substitute?

A: Yes. The main part is RoHS non-compliant. Substitutes should maintain equivalent regulatory status to ensure compatibility with existing design documentation and procurement specifications. REACH and ECCN classifications should remain consistent.

Q: What is the significance of the 1 Pair Common Cathode configuration?

A: This configuration specifies the internal diode arrangement within the package. It determines pin functionality and circuit connectivity. Substitutes must maintain this exact configuration to ensure proper circuit operation without modification.

Q: How does the fast recovery characteristic affect substitution?

A: Fast recovery (≤ 500 ns) is essential for high-frequency switching applications. Substitutes must maintain this speed specification to preserve circuit performance and prevent switching losses or timing issues.

Q: Can I substitute with a higher voltage-rated diode?

A: While a higher voltage rating would not damage the circuit, it would not constitute a true equivalent substitute. Engineering practice requires matching the specified 30 V rating to maintain design margins and thermal characteristics as originally intended.
