• Current - Average Rectified (Io) (per Diode): 10 A
• Voltage - Forward (Vf) (Max) @ If: 1.75 V @ 10 A
• Current - Reverse Leakage @ Vr: 100 µA @ 650 V
• Operating Temperature - Junction: -40°C to 175°C
• Diode Configuration: 1 Pair Common Cathode
• Technology: SiC (Silicon Carbide) Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Compliance Parameters:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Mounting Type: Through Hole

Package Considerations: Substitutes may differ in package type (TO-220-3 versus TO-247-3) provided the through-hole mounting requirement is maintained and PCB layout accommodates the physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

STPSC20H065CTY is the primary recommended substitute for the obsolete STPSC20H065CT. Both devices share identical electrical specifications, diode configuration, automotive qualification, and AEC-Q101 certification. The STPSC20H065CTY maintains the same TO-220-3 package footprint, enabling direct replacement without PCB redesign. The substitute is currently in active production status with confirmed inventory availability.

STPSC20H065CWY is a parametric equivalent substitute with identical electrical performance and automotive-grade compliance. This device differs in package type, utilizing a TO-247-3 through-hole configuration instead of TO-220-3. The TO-247-3 package accommodates higher thermal dissipation requirements and provides alternative mounting geometry. Selection of STPSC20H065CWY requires PCB layout modification to accommodate the larger package footprint. This substitute is currently in active production status with higher inventory availability.

Both substitute parts maintain full compliance with ROHS3 and automotive-grade AEC-Q101 qualification standards, ensuring regulatory and quality requirements are met for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can STPSC20H065CTY be used as a direct replacement for STPSC20H065CT?

A: Yes. STPSC20H065CTY is electrically and mechanically equivalent to STPSC20H065CT. Both devices feature identical voltage ratings (650 V), current ratings (10 A), forward voltage characteristics (1.75 V @ 10 A), and TO-220-3 package configuration. Direct PCB substitution is supported without design modification.

Q: What is the primary difference between STPSC20H065CTY and STPSC20H065CWY?

A: The primary difference is package type. STPSC20H065CTY uses TO-220-3 packaging, while STPSC20H065CWY uses TO-247-3 packaging. Both packages are through-hole mounted and electrically equivalent. The TO-247-3 package provides larger physical dimensions and enhanced thermal performance. PCB layout modification is required when substituting TO-220-3 with TO-247-3.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both STPSC20H065CTY and STPSC20H065CWY carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry standards and reliability requirements.

Q: What is the current product status of the substitute parts?

A: STPSC20H065CTY and STPSC20H065CWY are both classified as active products in current production. The original STPSC20H065CT is obsolete. Active product status ensures ongoing availability and manufacturing support.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. Both STPSC20H065CTY and STPSC20H065CWY are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to the original STPSC20H065CT.

Q: Can STPSC20H065CWY be used in applications designed for TO-220-3 packaging without modification?

A: No. STPSC20H065CWY uses TO-247-3 packaging with different physical dimensions and pin spacing. PCB layout and mounting hardware modification is required. Verify mechanical compatibility with your specific application before substitution.

Q: Are the electrical performance characteristics identical across all three part numbers?

A: Yes. STPSC20H065CT, STPSC20H065CTY, and STPSC20H065CWY share identical electrical specifications including voltage ratings, current ratings, forward voltage characteristics, reverse leakage current, operating temperature range, and fast recovery speed characteristics.
