Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR3050CT-BP are evaluated based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Package / Case: TO-220-3
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 150°C minimum
• Speed: Fast Recovery ≤500 ns, >200 mA (Io)

Voltage and Current Ratings: Substitute parts must maintain or exceed the DC reverse voltage (Vr) rating of 50 V and support the average rectified current (Io) requirement of 30 A per diode. Forward voltage characteristics and reverse leakage current must remain within acceptable operational parameters for the intended application.

Grouping Logic:

• Direct Equivalent (Manufacturer Recommended): MBR3060CT-BP meets all primary criteria with identical configuration, package, and performance characteristics. The increased voltage rating (60 V) provides enhanced margin while maintaining identical current capacity and forward voltage specifications.
• Similar Alternative (Reduced Current Rating): SR1650HC0G maintains the same voltage rating (50 V) and package configuration but operates at a reduced current rating (16 A per diode). This part is suitable only for applications where the 30 A current requirement can be reduced or where parallel configurations are implemented.

Engineering Selection Recommendations

MBR3060CT-BP (Manufacturer Recommended Substitute)

The MBR3060CT-BP is the primary substitute for the obsolete MBR3050CT-BP. This part is manufactured by the same supplier (Micro Commercial Co) and maintains identical electrical performance specifications with the exception of an increased DC reverse voltage rating (60 V versus 50 V). The MBR3060CT-BP is classified as Active product status, ensuring long-term availability and supply chain continuity. All electrical parameters including current capacity (30 A), forward voltage (950 mV @ 30 A), reverse leakage current (200 µA), and operating temperature range (-55°C ~ 150°C) are identical to the original part. The TO-220-3 package and through-hole mounting configuration provide direct mechanical compatibility. This part is suitable for direct replacement in all applications previously utilizing the MBR3050CT-BP.

SR1650HC0G (Similar Alternative)

The SR1650HC0G is an alternative Schottky diode array manufactured by Taiwan Semiconductor Corporation. This part maintains the same DC reverse voltage rating (50 V) and TO-220-3 package configuration as the original MBR3050CT-BP. However, the SR1650HC0G is rated for 16 A average rectified current per diode, which is below the 30 A requirement of the original part. The SR1650HC0G is classified as Active product status and carries AEC-Q101 automotive qualification. This part is suitable only for applications where the current requirement does not exceed 16 A per diode or where parallel diode configurations are implemented to achieve the required current capacity.

Frequently Asked Questions (FAQ)

Q: Can the MBR3060CT-BP be used as a direct replacement for the MBR3050CT-BP?

A: Yes. The MBR3060CT-BP is electrically and mechanically compatible with the MBR3050CT-BP. Both parts feature identical diode configuration (1 Pair Common Cathode), current rating (30 A), forward voltage (950 mV @ 30 A), and package (TO-220-3). The MBR3060CT-BP has a higher DC reverse voltage rating (60 V versus 50 V), which provides additional voltage margin without affecting performance in applications designed for 50 V operation.

Q: What is the primary difference between the MBR3050CT-BP and MBR3060CT-BP?

A: The primary difference is the maximum DC reverse voltage rating. The MBR3050CT-BP is rated for 50 V, while the MBR3060CT-BP is rated for 60 V. All other electrical parameters, including current capacity, forward voltage, and reverse leakage characteristics, are identical. The MBR3060CT-BP is also classified as Active product status, whereas the MBR3050CT-BP is obsolete.

Q: Can the SR1650HC0G replace the MBR3050CT-BP in all applications?

A: No. The SR1650HC0G has a reduced current rating (16 A per diode versus 30 A). This part is suitable only for applications where the current requirement does not exceed 16 A per diode. For applications requiring the full 30 A capacity, the SR1650HC0G is not a suitable direct replacement unless parallel configurations are implemented.

Q: Are the MBR3050CT-BP and MBR3060CT-BP pin-compatible?

A: Yes. Both parts use the TO-220-3 package with identical pin configuration and through-hole mounting. No PCB modifications are required for substitution.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: This configuration indicates that the diode array contains two diodes with a shared cathode terminal. The common cathode connection is a critical functional characteristic that must be maintained in substitute parts. Both recommended substitutes maintain this configuration.

Q: Does the MBR3060CT-BP have any compliance or certification differences from the MBR3050CT-BP?

A: Both parts share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99). The MBR3060CT-BP does not carry automotive qualification, whereas the SR1650HC0G carries AEC-Q101 automotive qualification. Compliance requirements should be evaluated based on the specific application.

Q: What is the reverse leakage current difference between the MBR3050CT-BP and SR1650HC0G?

A: The MBR3050CT-BP has a reverse leakage current of 200 µA @ 50 V, while the SR1650HC0G has a reverse leakage current of 500 µA @ 50 V. The higher leakage current in the SR1650HC0G may impact thermal performance in applications sensitive to leakage current characteristics.

Q: Are there any thermal considerations when substituting these parts?

A: All three parts share the same operating temperature range (-55°C ~ 150°C). However, the SR1650HC0G has a lower current rating (16 A), which results in lower power dissipation compared to the 30 A rated parts. Thermal design calculations should account for the specific current and voltage characteristics of the selected part.
