SBL2060CT Equivalent & Substitute Parts

Part Overview

The SBL2060CT is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode with 60 V reverse voltage rating and 20 A average rectified current per diode. The device is packaged in TO-220-3 through-hole format 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.

Voltage - DC Reverse (Vr) (Max): 60 V (mandatory match)
Current - Average Rectified (Io) (per Diode): 20 A minimum (equal or greater)
Technology: Schottky (preferred for performance continuity)
Mounting Type: Through Hole (mandatory match)
Package / Case: TO-220-3 (mandatory match)

Secondary Compatibility Factors:

Forward voltage characteristics within acceptable operating range
Reverse leakage current specifications

Engineering Selection Recommendations

Direct Current-Rated Equivalents (20 A):

The following parts provide direct electrical equivalence to the SBL2060CT with 20 A current rating and are recommended as primary substitutes:

STPS40M60CT (STMicroelectronics): Active product status, ROHS3 compliant, REACH unaffected. Forward voltage of 595 mV @ 20 A provides improved thermal performance compared to the original part.
MBR2060CT (Taiwan Semiconductor Corporation): Active product status, ROHS3 compliant, REACH unaffected. Maintains 20 A current rating with 60 V reverse voltage specification.
MBR2060CT-BP (Micro Commercial Co): Active product status, REACH unaffected. Packaged in bulk format, suitable for high-volume applications.

Higher Current-Rated Alternatives (30 A):

For applications requiring additional current margin or thermal headroom:

DSB60C60PB (IXYS): Active product status, ROHS3 compliant, REACH unaffected. 30 A current rating with operating temperature range to 150°C.
DSA60C60PB (IXYS): Active product status, ROHS3 compliant, REACH unaffected. 30 A current rating with extended operating temperature range to 175°C.

Lower Current Alternatives (10-15 A):

For applications with reduced current requirements:

SBR3060CT (Diodes Incorporated): Active product status, ROHS3 compliant, REACH unaffected. Super Barrier technology with 15 A rating and extended temperature range to -65°C.
DSB30C60PB (IXYS): Active product status, ROHS3 compliant, REACH unaffected. 15 A current rating with 60 V reverse voltage.
STPS20L60CT (STMicroelectronics): Active product status, ROHS3 compliant, REACH unaffected. 10 A current rating with low forward voltage of 600 mV @ 10 A.

All recommended substitutes maintain TO-220-3 through-hole packaging, 1 Pair Common Cathode configuration, and fast recovery Schottky technology specifications.

Frequently Asked Questions (FAQ)

Q: Can STPS20L60CT (10 A) be used as a substitute for SBL2060CT (20 A)?

A: STPS20L60CT is not a direct equivalent due to its 10 A current rating, which is 50% lower than the SBL2060CT specification. This part is suitable only for applications with reduced current requirements. For full 20 A operation, use STPS40M60CT, MBR2060CT, or MBR2060CT-BP.

Q: What is the difference between Schottky and Super Barrier technology in these diodes?

A: Both technologies are fast recovery diode types with similar switching characteristics. SBR3060CT uses Super Barrier technology and is rated for 15 A, while the SBL2060CT uses standard Schottky technology at 20 A. Technology selection depends on application current requirements and thermal management capabilities.

Q: Are the 30 A rated parts (DSB60C60PB, DSA60C60PB) backward compatible with the 20 A SBL2060CT?

A: Yes. The 30 A parts maintain identical 60 V reverse voltage, 1 Pair Common Cathode configuration, and TO-220-3 packaging. Higher current rating provides additional design margin and thermal headroom. Forward voltage characteristics differ slightly but remain within acceptable operating ranges for most applications.

Q: What is the significance of forward voltage differences between substitute parts?

A: Forward voltage (Vf) affects power dissipation and thermal performance. Lower Vf values (STPS40M60CT at 595 mV @ 20 A) result in reduced heat generation compared to higher Vf values (MBR2060CT at 950 mV @ 20 A). Selection depends on thermal design constraints and power budget requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are ROHS3 compliant. Compliance status is verified in the product specifications. REACH status varies by manufacturer; refer to individual part specifications for regulatory requirements in specific markets.

Q: Can MBR1060CTL be used as a substitute despite unspecified current rating?

A: MBR1060CTL specifications do not include current rating data. This part is not recommended as a direct substitute for the 20 A SBL2060CT. Use only when current requirements are confirmed to be compatible with the device design.

Q: What packaging format differences exist between substitute parts?

A: All substitute parts use TO-220-3 through-hole packaging. Supplier device package designations (TO-220-3, TO-220AB, TO-220) refer to the same physical form factor. Packaging format variations (Tube, Bulk) affect ordering and handling but do not impact electrical compatibility.

Q: Is the SBL2060CT obsolete status a concern for new designs?

A: Yes. The SBL2060CT is classified as obsolete, making it unavailable for new production. Active substitute parts such as STPS40M60CT, MBR2060CT, or DSB60C60PB must be used for new designs to ensure long-term component availability and supply chain continuity.
