Compliance Parameters:

• RoHS Status: ROHS3 Compliant required
• ECCN: EAR99 (all parts match)
• HTSUS: 8541.10.0080 (all parts match)

Substitute parts meeting these criteria are electrically and mechanically compatible for direct replacement in applications designed for the STPSC6H065DI.

Parameter Comparison

Engineering Selection Recommendations

STPSC6H065DI (STMicroelectronics) - Primary Reference

The STPSC6H065DI serves as the baseline component. It is active, ROHS3 compliant, and REACH unaffected. Current inventory of 80,300 pieces supports standard procurement cycles.

PCDP0665G1_T0_00001 (Panjit International Inc.) - Direct Substitute

This part is electrically equivalent with forward voltage 0.05 V lower than the main part (1.7 V vs. 1.75 V @ 6 A), indicating improved efficiency characteristics. Reverse leakage is 50 µA, lower than the main part. Operating temperature range extends to -55°C, providing broader thermal coverage. Reverse recovery time is 0 ns, indicating superior switching performance. RoHS3 compliance and EAR99 classification match the main part. Inventory of 3,140 pieces is available. Package designation is TO-220AC, consistent with the main part.

S3D06065I (SMC Diode Solutions) - Direct Substitute

This part meets all mandatory electrical parameters with forward voltage of 1.7 V @ 6 A and reverse leakage of 8 µA, the lowest among all three parts. Reverse recovery time is 0 ns. Operating temperature range extends to -55°C. RoHS3 compliance is confirmed. Package is TO-220-2 Isolated Tab, providing electrical isolation between the tab and the case, which may be required in specific circuit topologies. Inventory of 1,695 pieces is available. REACH status is affected, requiring verification against specific regulatory requirements in the application region.

All three parts are classified under HTSUS 8541.10.0080 and ECCN EAR99, supporting consistent supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can PCDP0665G1_T0_00001 or S3D06065I be used as direct replacements for STPSC6H065DI in existing designs?

A: Yes. Both substitute parts meet the mandatory electrical specifications: 650 V reverse voltage, 6 A average rectified current, and SiC Schottky technology. All three parts are through-hole mounted in TO-220 package variants. Electrical performance is equivalent or superior in forward voltage drop and reverse leakage characteristics.

Q: What is the difference between the TO-220AC insulated package and the TO-220-2 Isolated Tab package?

A: The TO-220AC insulated package (STPSC6H065DI and PCDP0665G1_T0_00001) features electrical isolation between the mounting tab and the semiconductor die. The TO-220-2 Isolated Tab package (S3D06065I) also provides isolation. Both configurations support isolated mounting applications. Physical dimensions and mounting hole patterns are compatible within TO-220 family specifications.

Q: How do the reverse leakage currents compare among the three parts?

A: STPSC6H065DI specifies 60 µA @ 650 V. PCDP0665G1_T0_00001 specifies 50 µA @ 650 V. S3D06065I specifies 8 µA @ 650 V. Lower reverse leakage indicates reduced standby power dissipation and improved efficiency in applications with extended off-state operation.

Q: Are there temperature range differences that affect part selection?

A: STPSC6H065DI operates from -40°C to 175°C junction temperature. Both PCDP0665G1_T0_00001 and S3D06065I extend the lower limit to -55°C. Applications requiring operation below -40°C require the substitute parts. The upper temperature limit of 175°C is identical across all three parts.

Q: What is the significance of zero reverse recovery time in the substitute parts?

A: Reverse recovery time (trr) of 0 ns indicates that the diode transitions from forward conduction to reverse blocking state instantaneously, with no stored charge to remove. This characteristic reduces switching losses and electromagnetic interference in high-frequency power conversion circuits. The main part specifies fast recovery ≤ 500 ns, which is acceptable for most applications but generates slightly higher switching losses compared to zero-recovery devices.

Q: Does REACH status affect part selection?

A: STPSC6H065DI and PCDP0665G1_T0_00001 are REACH unaffected. S3D06065I is REACH affected, requiring verification against specific regulatory requirements in the application region and end-use market. Consult regional compliance documentation before selecting S3D06065I for applications subject to REACH restrictions.

Q: Are all three parts RoHS3 compliant?

A: Yes. STPSC6H065DI, PCDP0665G1_T0_00001, and S3D06065I are all ROHS3 compliant, supporting use in applications requiring restriction of hazardous substances.

Q: What inventory levels are available for each part?

A: STPSC6H065DI: 80,300 pieces. PCDP0665G1_T0_00001: 3,140 pieces. S3D06065I: 1,695 pieces. Inventory availability should be verified at time of procurement to confirm current stock levels.
