STPS30H60CW Equivalent & Substitute Parts

Part Overview

The STPS30H60CW is a Schottky diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 60 V reverse voltage rating and 15 A average rectified current per diode. The device is packaged in TO-247-3 through-hole configuration and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the STPS30H60CW is determined by the following critical parameters:

Mandatory Matching Parameters:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 60 V
Mounting Type: Through Hole
Package / Case: TO-247-3

Current Rating Considerations: Substitute parts are grouped into two categories based on average rectified current per diode:

Direct Current Rating Match (15 A): Parts with identical 15 A current rating provide pin-for-pin electrical equivalence with no circuit redesign required.
Higher Current Rating (30 A and 40 A): Parts with elevated current ratings (30 A or 40 A) are suitable for applications where the STPS30H60CW operates below its maximum current specification. These substitutes provide enhanced current handling capability and are backward compatible in circuits designed for 15 A operation.

Compliance and Status Considerations: Active product status and ROHS3 compliance are preferred for new designs and long-term availability. Obsolete parts with non-compliant status are listed for reference but are not recommended for new production applications.

Engineering Selection Recommendations

For Direct Replacement (15 A Current Rating):

The 30CPQ060 from Vishay General Semiconductor provides identical electrical specifications with matching 15 A current rating. However, this part is obsolete and RoHS non-compliant, making it unsuitable for new production applications. The MBR3060WT from SMC Diode Solutions is an active product with ROHS3 compliance and is the preferred direct replacement for the STPS30H60CW in applications requiring 15 A operation.

For Enhanced Current Capability (30 A and 40 A Ratings):

The DSB60C60HB (30 A) and DSSK80-006B (40 A) from IXYS, along with the MBR3060PT (30 A) from Taiwan Semiconductor Corporation, are active products with ROHS3 compliance. These parts are suitable for applications where the STPS30H60CW operates below its maximum 15 A specification. The DSSK80-006B offers the lowest forward voltage drop at 550 mV @ 40 A, providing improved thermal performance in high-current applications.

Compliance Considerations:

All recommended active substitutes are ROHS3 compliant, meeting current regulatory requirements for new production. The 30CPQ060, while electrically compatible, is RoHS non-compliant and obsolete, and is not recommended for new designs.

Product Status Priority:

Active products (MBR3060WT, DSB60C60HB, DSSK80-006B, MBR3060PT) are preferred over obsolete parts for long-term design continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the MBR3060WT be used as a direct replacement for the STPS30H60CW?

A: Yes. The MBR3060WT shares the same diode configuration (1 pair common cathode), technology (Schottky), reverse voltage rating (60 V), and TO-247-3 package. It is an active product with ROHS3 compliance. The forward voltage specification differs slightly (770 mV @ 15 A versus 660 mV @ 15 A), which is within acceptable tolerance for most applications.

Q: What is the difference between the 15 A, 30 A, and 40 A rated substitutes?

A: The current rating indicates the maximum average rectified current per diode. The STPS30H60CW is rated for 15 A. Substitutes with 30 A or 40 A ratings can handle higher currents and are backward compatible in circuits where the STPS30H60CW operates below its maximum specification. Selection depends on the actual circuit current requirements.

Q: Is the 30CPQ060 a suitable substitute?

A: The 30CPQ060 is electrically compatible with matching 15 A current rating and identical package. However, it is classified as obsolete and is RoHS non-compliant. It is not recommended for new production applications. Use the MBR3060WT instead.

Q: Why do some substitute parts have higher reverse leakage current specifications?

A: Reverse leakage current varies by manufacturer and device design. The STPS30H60CW specifies 60 µA @ 60 V, while substitutes range from 1 mA to 800 µA. Higher leakage does not prevent substitution but may affect circuit performance in applications sensitive to leakage current. Verify leakage specifications against circuit requirements.

Q: Are all substitute parts available in the same TO-247-3 package?

A: Yes. All listed substitute parts use the TO-247-3 through-hole package, ensuring mechanical and pin compatibility with the STPS30H60CW.

Q: Which substitute offers the best thermal performance?

A: The DSSK80-006B (40 A rating) exhibits the lowest forward voltage drop at 550 mV @ 40 A, resulting in reduced power dissipation and improved thermal performance in high-current applications.

Q: Can I use a 30 A or 40 A rated substitute in a circuit designed for the 15 A STPS30H60CW?

A: Yes. Higher-rated substitutes are backward compatible. If the circuit operates at or below 15 A, the 30 A and 40 A rated parts function correctly. Verify that the circuit design does not depend on specific current-limiting characteristics of the 15 A device.
