STPS20M60CT Equivalent & Substitute Parts

Part Overview

The STPS20M60CT is a Schottky diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 60 V reverse voltage rating and 10 A average rectified current per diode. The device is packaged in TO-220-3 through-hole configuration and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical and mechanical specifications while offering improved availability and extended product lifecycles.

Substitute Part Grouping Explanation

Substitution of the STPS20M60CT is determined by the following core parameters:

Primary Substitution Criteria:

Diode Configuration: 1 Pair Common Cathode (mandatory match)
Technology: Schottky (mandatory match)
Voltage - DC Reverse (Vr) (Max): 60 V (mandatory match)
Mounting Type: Through Hole (mandatory match)
Package / Case: TO-220-3 (mandatory match)

Secondary Compatibility Parameters:

Current - Average Rectified (Io) (per Diode): 10 A or greater
Voltage - Forward (Vf) (Max) @ If: ≤ 570 mV @ 10 A or equivalent rating
Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (mandatory match)
Operating Temperature - Junction: ≥ 150°C (Max)

Engineering Selection Recommendations

Direct Replacement Candidates (Active Status):

The following parts are recommended for direct replacement of the STPS20M60CT in new designs and production:

RB215T-60 (Rohm Semiconductor): Active product status with matching 10 A current rating, 60 V reverse voltage, and 150°C maximum junction temperature. Forward voltage of 580 mV @ 10 A is within acceptable tolerance of the original 570 mV specification. ROHS3 compliant and REACH unaffected. TO-220-3 Full Pack configuration maintains mechanical compatibility.

DST2060C (Littelfuse Inc.): Active product status with matching 10 A current rating and 60 V reverse voltage. Operating temperature range of −55°C to 150°C exceeds the original specification. Forward voltage of 645 mV @ 10 A represents a 13% increase over the original specification; circuit-level verification is required for applications with tight forward voltage budgets. ROHS3 compliant and REACH unaffected.

MBR1060CTL (SMC Diode Solutions): Active product status with 60 V reverse voltage and 150°C maximum junction temperature. Forward voltage of 600 mV @ 5 A is specified at lower current; application verification is required for 10 A operation. ROHS3 compliant with REACH affected status. Reverse leakage of 1 mA @ 60 V is elevated compared to the original 65 µA specification.

Higher Current Alternatives (Active Status):

MBR2060CT (Taiwan Semiconductor Corporation): Active product status with 20 A current rating, 60 V reverse voltage, and 150°C maximum junction temperature. Provides current margin above the original 10 A specification. Forward voltage of 950 mV @ 20 A is specified at higher current; direct comparison at 10 A operation requires manufacturer datasheet verification. ROHS3 compliant and REACH unaffected. Highest inventory availability (17,095 pcs).

DST3060LC (Littelfuse Inc.): Active product status with 15 A current rating and 60 V reverse voltage. Forward voltage of 550 mV @ 15 A is superior to the original specification. Operating temperature range of −55°C to 125°C has reduced maximum junction temperature (125°C vs. 150°C); thermal design verification is required for high-temperature applications. ROHS3 compliant and REACH unaffected.

Lower Current Alternative (Active Status):

MBR1060CT-G1 (Diodes Incorporated): Active product status with 5 A current rating. Suitable only for applications where the circuit current requirement does not exceed 5 A. Forward voltage of 750 mV @ 5 A is elevated. ROHS3 compliant and REACH unaffected.

Obsolete Status Parts (Not Recommended for New Designs):

MBR2060CTP, MBR2060CTL, and MBR30L60CTG are classified as obsolete and should not be selected for new production designs despite active inventory availability.

Frequently Asked Questions (FAQ)

Q: Can MBR2060CT be used as a direct replacement for STPS20M60CT?

A: MBR2060CT meets all primary substitution criteria: 1 pair common cathode configuration, Schottky technology, 60 V reverse voltage, through-hole mounting, TO-220-3 package, fast recovery speed, ROHS3 compliance, and MSL 1 rating. The 20 A current rating exceeds the original 10 A specification, providing design margin. Forward voltage is specified at 950 mV @ 20 A; verification at 10 A operation is required through manufacturer datasheet or application notes. Product status is active with high inventory availability.

Q: What is the difference between RB215T-60 and DST2060C?

A: Both parts meet primary substitution criteria with 10 A current rating and 60 V reverse voltage. RB215T-60 (Rohm Semiconductor) has forward voltage of 580 mV @ 10 A, closely matching the original 570 mV specification. DST2060C (Littelfuse Inc.) has forward voltage of 645 mV @ 10 A, representing a 13% increase. RB215T-60 uses TO-220-3 Full Pack configuration; DST2060C uses standard TO-220-3. Both are active products with ROHS3 compliance. Selection depends on forward voltage budget and thermal design constraints.

Q: Why is MBR1060CTL listed as a substitute if it has lower current rating?

A: MBR1060CTL meets all primary substitution criteria and is active product status. However, the current rating is not specified in the provided data. Forward voltage is specified at 5 A (600 mV), not at 10 A. This part is suitable only for applications where circuit current does not exceed the unspecified rating. Application-level verification is mandatory before selection.

Q: Can DST3060LC be used in high-temperature applications?

A: DST3060LC has maximum junction temperature of 125°C, which is 25°C lower than the original STPS20M60CT specification of 150°C. For applications requiring sustained operation at temperatures above 125°C, this part is not suitable. RB215T-60, MBR2060CT, MBR1060CTL, and MBR2060CTP maintain the 150°C maximum junction temperature rating.

Q: What does "TO-220-3 Isolated Tab" mean for MBR2060CTP?

A: The isolated tab configuration (ITO-220S package) provides electrical isolation between the mounting tab and the diode cathode, unlike standard TO-220-3 where the tab is electrically connected to the cathode. This affects thermal management and circuit layout. Verify that the application circuit design accommodates isolated tab configuration before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. However, REACH status varies: MBR2060CTL and MBR2060CTP are REACH affected, while RB215T-60, DST2060C, DST3060LC, MBR1060CT-G1, MBR1060CTL, and MBR2060CT are REACH unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the significance of reverse leakage current differences?

A: The original STPS20M60CT has reverse leakage of 65 µA @ 60 V. Substitute parts show variation: DST3060LC (300 µA), MBR30L60CTG (350 µA), MBR2060CTP and MBR2060CT (100 µA), RB215T-60 (600 µA), DST2060C (850 µA), and MBR2060CTL and MBR1060CTL (1000 µA). Higher reverse leakage increases power dissipation and heat generation. For applications sensitive to leakage current, select parts with lower reverse leakage specifications.

Q: Which substitute part has the best forward voltage match?

A: DST3060LC has forward voltage of 550 mV @ 15 A, which is superior to the original 570 mV @ 10 A specification. RB215T-60 has 580 mV @ 10 A, representing a 1.8% increase. MBR1060CTL has 600 mV @ 5 A. For applications with tight forward voltage budgets, DST3060LC or RB215T-60 are preferred; however, DST3060LC has reduced maximum junction temperature (125°C vs. 150°C).

Q: Can I use MBR1060CT-G1 in place of STPS20M60CT?

A: MBR1060CT-G1 meets all primary substitution criteria but has 5 A current rating, which is half the original 10 A specification. This part is suitable only for applications where the circuit current requirement does not exceed 5 A. Forward voltage of 750 mV @ 5 A is elevated compared to the original specification. Use only if application current is confirmed below 5 A.
