STPS41L60CG Equivalent & Substitute Parts

Part Overview

The STPS41L60CG is a Schottky diode array manufactured by STMicroelectronics, configured as 1 pair common cathode with 60 V reverse voltage rating and 20 A average rectified current per diode. The device is packaged in TO-263-3 (D2PAK) surface mount configuration and is classified as obsolete product status. Due to its obsolete classification, equivalent and substitute parts from active manufacturers are necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STPS41L60CG is determined by the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (pinout compatibility)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (mechanical and thermal compatibility)
• Voltage - DC Reverse (Vr) (Max): 60 V (electrical rating match)
• Technology: Schottky (switching characteristics and forward voltage behavior)
• Mounting Type: Surface Mount (assembly process compatibility)

Secondary Compatibility Parameters:

• Current - Average Rectified (Io) (per Diode): Equal to or greater than 20 A
• Voltage - Forward (Vf) (Max) @ If: Within acceptable circuit operating margins
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: Minimum 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: direct equivalents (matching all primary criteria with 20 A current rating) and functional alternatives (matching primary criteria with current ratings above 20 A, suitable for applications with design margin requirements).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Primary Selection):

The 48CTQ060S from SMC Diode Solutions is the primary direct equivalent to the STPS41L60CG. Both devices share identical diode configuration, voltage rating, current rating, and package specifications. The 48CTQ060S is active product status with ROHS3 compliance and MSL 1 rating. Forward voltage specification (610 mV @ 20 A) is within 10 mV of the original part, maintaining circuit performance characteristics. The device is available in Cut Tape and Digi-Reel packaging formats.

Alternative Equivalents (Secondary Selection):

The SRS2060HMNG from Taiwan Semiconductor Corporation provides functional equivalence with identical 20 A current rating and 60 V voltage rating in TO-263-3 D2PAK package. This device utilizes standard diode technology rather than Schottky technology, resulting in higher forward voltage (700 mV @ 10 A). The SRS2060HMNG carries AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade components. Product status is active with ROHS3 compliance.

Functional Alternatives (Higher Current Rating):

The NRVBB30H60CTT4G from onsemi provides 15 A current rating with 60 V voltage rating in identical TO-263-3 D2PAK package. This device offers extended operating temperature range to 175°C and lower reverse leakage current (300 µA @ 60 V). The NRVBB30H60CTT4G is suitable for applications where thermal margin or lower leakage performance is required.

The MBRB2060CT from Littelfuse Inc. provides 10 A current rating with 60 V voltage rating. This device is active product status with ROHS3 compliance and is suitable for applications with reduced current requirements or where design margin is not critical.

Not Recommended for Direct Substitution:

The MBRB1060CT from Littelfuse Inc. provides only 5 A current rating, which is insufficient for the 20 A requirement of the STPS41L60CG and is not suitable for direct substitution in applications requiring full 20 A capacity.

Frequently Asked Questions (FAQ)

Q: Can the 48CTQ060S directly replace the STPS41L60CG in existing designs?

A: Yes. The 48CTQ060S is a direct equivalent with matching diode configuration (1 pair common cathode), voltage rating (60 V), current rating (20 A per diode), and package (TO-263-3 D2PAK). Pin assignments and thermal characteristics are identical. No circuit modifications are required.

Q: What is the difference between Schottky and Standard diode technology in these parts?

A: The STPS41L60CG and most substitute parts use Schottky technology, which provides lower forward voltage drop and faster switching characteristics. The SRS2060HMNG uses standard diode technology, resulting in higher forward voltage (700 mV @ 10 A versus 600-620 mV for Schottky devices). Standard diodes are suitable for applications where switching speed is not critical and higher forward voltage is acceptable.

Q: Why do some substitute parts have higher current ratings than 20 A?

A: Parts such as the NRVBB30H60CTT4G (15 A) and MBRB2060CT (10 A) are functional alternatives that can operate in circuits designed for the STPS41L60CG. Higher current ratings provide design margin and thermal headroom. Lower current ratings (such as MBRB1060CT at 5 A) are not suitable for applications requiring the full 20 A capacity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original STPS41L60CG.

Q: What is the significance of the TO-263-3 D2PAK package specification?

A: The TO-263-3 D2PAK package is a surface mount configuration with 2 leads plus a thermal tab. This package specification ensures mechanical compatibility with existing PCB layouts and assembly processes. All substitute parts maintain this identical package specification, allowing direct board-level substitution without layout modifications.

Q: Can the MBRB1060CT be used as a substitute?

A: The MBRB1060CT is not suitable for direct substitution due to its 5 A current rating, which is significantly below the 20 A requirement of the STPS41L60CG. This part is listed as a reference only and should not be selected for applications requiring 20 A capacity.

Q: What is the operating temperature range consideration for substitute selection?

A: The STPS41L60CG specifies maximum junction temperature of 150°C. All substitute parts meet or exceed this specification. The NRVBB30H60CTT4G extends to 175°C, providing additional thermal margin. For applications operating near thermal limits, the NRVBB30H60CTT4G is the preferred alternative.

Q: How does reverse leakage current affect substitute part selection?

A: Reverse leakage current is specified at maximum reverse voltage (60 V). The STPS41L60CG specifies 600 µA, while substitute parts range from 300 µA to 2 mA. Lower leakage current (NRVBB30H60CTT4G at 300 µA) is beneficial for low-power standby applications. Higher leakage (48CTQ060S at 2 mA) is acceptable for most power conversion applications where leakage current is negligible relative to load current.
