STTH60AC06CP Equivalent & Substitute Parts

Part Overview

The STTH60AC06CP is a general-purpose diode array manufactured by STMicroelectronics, configured as a 1 Pair Common Cathode rectifier with 600 V reverse voltage rating and 30 A average rectified current per diode. The device is packaged in TO-3P-3 (SC-65-3) through-hole configuration and is classified as obsolete. Due to its obsolete product status, identification of functionally equivalent substitute components is necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution of the STTH60AC06CP is determined by electrical and mechanical parameter equivalence within the diode rectifier category. The substitute part STTH60AC06CW shares the same base product number (STTH60) and maintains identical electrical specifications across all critical parameters: 600 V reverse voltage rating, 30 A average rectified current per diode, 1.75 V forward voltage at 30 A, 40 ns reverse recovery time, and 10 µA reverse leakage current at 600 V. Both devices employ standard technology with fast recovery characteristics and operate to a maximum junction temperature of 175°C.

The primary distinction between the main part and substitute is the package configuration. The STTH60AC06CP utilizes TO-3P-3 (SC-65-3) packaging, while the STTH60AC06CW is supplied in TO-247-3 packaging. Both are through-hole mounting types. The substitute part carries active product status with higher current inventory availability, whereas the main part is classified as obsolete.

Substitution is valid when the TO-247-3 package footprint is compatible with the application's printed circuit board layout and thermal management requirements.

Engineering Selection Recommendations

The STTH60AC06CW serves as a direct electrical substitute for the STTH60AC06CP, with all electrical parameters and performance characteristics held to identical specifications. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across applications.

The primary consideration for component selection is package compatibility. The STTH60AC06CP employs TO-3P-3 (SC-65-3) packaging, while the STTH60AC06CW utilizes TO-247-3 packaging. These packages have different footprints, lead configurations, and thermal characteristics. PCB layout modifications are required if transitioning from the main part to the substitute.

The STTH60AC06CW is recommended for new designs and ongoing production due to its active product status and established supply chain availability. The STTH60AC06CP, classified as obsolete, should be replaced with the STTH60AC06CW in applications where package footprint changes are feasible.

Frequently Asked Questions (FAQ)

Q: Are the electrical specifications identical between STTH60AC06CP and STTH60AC06CW?

A: Yes. Both components share identical electrical specifications: 600 V reverse voltage rating, 30 A average rectified current per diode, 1.75 V forward voltage at 30 A, 40 ns reverse recovery time, and 10 µA reverse leakage current at 600 V. Operating temperature range and technology classification are also identical.

Q: What is the primary difference between these two parts?

A: The primary difference is the package configuration. The STTH60AC06CP is supplied in TO-3P-3 (SC-65-3) packaging, while the STTH60AC06CW is supplied in TO-247-3 packaging. Both are through-hole mounting types with different physical footprints and lead arrangements.

Q: Can I directly replace STTH60AC06CP with STTH60AC06CW on an existing PCB?

A: Direct replacement on an existing PCB is not possible without layout modification. The TO-3P-3 and TO-247-3 packages have different footprints and lead configurations. PCB redesign is required to accommodate the TO-247-3 package if substituting the STTH60AC06CW.

Q: Why is the STTH60AC06CP classified as obsolete?

A: The STTH60AC06CP is listed as obsolete by the manufacturer. The STTH60AC06CW, with active product status, represents the current production equivalent and is recommended for new designs and ongoing applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the STTH60AC06CP and STTH60AC06CW are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these components?

A: Both components carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
