SR1060 Equivalent & Substitute Parts

Part Overview

The SR1060 is a Schottky rectifier diode rated for 60 V DC reverse voltage and 10 A average rectified current, housed in a TO-220-3 through-hole package. This single-diode configuration is designed for fast recovery applications with forward voltage of 700 mV at 5 A and reverse leakage of 500 µA at 60 V. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are necessary when the original SR1060 becomes unavailable or when alternative diode array configurations with equivalent electrical ratings are required for system integration.

Substitute Part Grouping Explanation

Substitution of the SR1060 is determined by the following critical parameters: voltage rating (60 V DC reverse), current capacity (10 A per diode), Schottky technology, fast recovery speed (≤ 500 ns), through-hole mounting in TO-220-3 package, and operating temperature range (-55°C to 150°C). The substitute parts listed—MBR1060CT, MBR1060CTL, and MBR1060CTP—are diode array configurations with 1 pair common cathode topology. These parts maintain the 60 V voltage rating and fast recovery characteristics required for equivalent circuit operation. While the substitute parts are configured as diode arrays rather than single diodes, they provide the same per-diode current capacity and voltage specifications within the same thermal and mechanical envelope. Substitution is valid when the application circuit can accommodate the common cathode configuration or when only one diode element of the array is utilized.

Engineering Selection Recommendations

SR1060 (Primary Selection): The SR1060 remains the preferred component for new designs. It is actively produced, maintains REACH Unaffected status, and provides the specified electrical characteristics in a single-diode configuration. Inventory of 1,647 pieces is available.

MBR1060CTL (Recommended Substitute): This part is actively produced by SMC Diode Solutions and offers the lowest forward voltage (600 mV @ 5 A) among the substitutes, resulting in reduced power dissipation. It maintains RoHS3 compliance and is available in tube packaging with 2,200 pieces in stock. The REACH Affected status requires compliance verification for applications subject to REACH regulations.

MBR1060CTP (Alternative Substitute): This part matches the SR1060 forward voltage specification (700 mV @ 5 A) and is actively produced by SMC Diode Solutions. It provides an alternative when MBR1060CTL is unavailable. REACH Affected status applies. Inventory of 2,650 pieces is available.

MBR1060CT (Not Recommended for New Designs): This part is discontinued at DiGi Electronics and should not be selected for new applications despite adequate inventory (25,300 pieces). Its discontinuation status indicates reduced long-term availability and support.

Frequently Asked Questions (FAQ)

Q: Can the MBR1060CT, MBR1060CTL, and MBR1060CTP be used as direct replacements for the SR1060?

A: These parts are diode array configurations with 1 pair common cathode topology, whereas the SR1060 is a single diode. Direct replacement is possible only if the application circuit can accommodate the common cathode configuration or if only one diode element of the array is utilized. The per-diode electrical ratings (60 V, 10 A, fast recovery) are equivalent.

Q: What is the difference in forward voltage between the SR1060 and the substitute parts?

A: The SR1060 specifies 700 mV @ 5 A. The MBR1060CT specifies 900 mV @ 10 A, the MBR1060CTL specifies 600 mV @ 5 A, and the MBR1060CTP specifies 700 mV @ 5 A. Forward voltage varies with current level; direct comparison requires measurement at identical current conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (MBR1060CT, MBR1060CTL, MBR1060CTP) are RoHS3 compliant. However, MBR1060CTL and MBR1060CTP carry REACH Affected status, while the SR1060 and MBR1060CT are REACH Unaffected.

Q: What is the significance of the common cathode configuration in the substitute parts?

A: The common cathode configuration means two diode elements share a common cathode terminal within the TO-220-3 package. This affects PCB layout and circuit design. Applications using only one diode element can ignore the second element, but the package footprint and pinout differ from the single-diode SR1060.

Q: Which substitute part offers the best thermal performance?

A: All substitute parts share the same TO-220-3 package and -55°C to 150°C operating temperature range as the SR1060. Thermal performance is determined by package design and application-specific heat sinking, not by the electrical specifications provided.

Q: Is the SR1060 still in production?

A: Yes, the SR1060 is actively produced by Taiwan Semiconductor Corporation with 1,647 pieces currently in stock.

Q: What is the reverse leakage current difference between the SR1060 and substitutes?

A: The SR1060 specifies 500 µA @ 60 V. The MBR1060CT specifies 100 µA @ 60 V (lower leakage), while MBR1060CTL and MBR1060CTP both specify 1 mA @ 60 V (higher leakage). Lower reverse leakage reduces standby power consumption in certain applications.
