MBR1530CT Equivalent & Substitute Parts

Part Overview

The MBR1530CT is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 pair common cathode with a maximum reverse voltage of 30 V and average rectified current of 15 A per diode. The device is packaged in TO-220-3 through-hole configuration and is classified as obsolete product status.

Due to obsolescence, locating original MBR1530CT units may present supply chain challenges. Substitute parts with compatible electrical and mechanical specifications are available to maintain design functionality and performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR1530CT is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must remain 1 pair common cathode
• Technology must be Schottky
• Reverse voltage rating must equal or exceed 30 V
• Average rectified current per diode must equal or exceed 15 A
• Forward voltage drop must not exceed 840 mV @ 15 A
• Recovery speed must be fast recovery ≤ 500ns, > 200mA (Io)
• Reverse leakage current must not exceed 100 µA @ 30 V

Mechanical Compatibility Requirements:

• Mounting type must be through hole
• Package must be TO-220-3
• Moisture sensitivity level must be 1 (Unlimited)

The MBR1535CTG from onsemi meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MBR1535CTG from onsemi presents a substitution option with the following considerations based on provided specifications:

Advantages:

• Higher reverse voltage rating (35 V vs. 30 V) provides additional voltage margin
• Extended operating temperature range (-65°C ~ 175°C vs. -65°C ~ 150°C)
• ROHS3 compliant, matching environmental compliance requirements
• Identical forward voltage characteristics at specified current
• Identical fast recovery speed specification
• Identical moisture sensitivity level (MSL 1)
• Through-hole TO-220-3 package maintains mechanical compatibility

Limitation:

• Average rectified current per diode is 7.5 A, which is lower than the MBR1530CT specification of 15 A. This represents a 50% reduction in current-handling capability per diode and must be evaluated against application requirements.

Both parts are classified as obsolete. The MBR1535CTG is suitable for applications where the 7.5 A per-diode current rating is sufficient for the intended circuit design.

Frequently Asked Questions (FAQ)

Q: Can the MBR1535CTG directly replace the MBR1530CT in all applications?

A: The MBR1535CTG is mechanically compatible (TO-220-3 package, through-hole mounting) and electrically compatible in voltage and temperature specifications. However, the current rating per diode is 7.5 A versus 15 A for the MBR1530CT. Direct replacement is only suitable for applications where the circuit current requirements do not exceed 7.5 A per diode.

Q: What is the significance of the 1 pair common cathode configuration?

A: This configuration indicates the diode array contains two diodes sharing a common cathode terminal. Both the MBR1530CT and MBR1535CTG maintain this identical configuration, ensuring pin-compatible operation in circuits designed for this topology.

Q: Are there differences in forward voltage drop between these parts?

A: Both parts specify 840 mV maximum forward voltage at 15 A. This parameter is identical between the MBR1530CT and MBR1535CTG, ensuring equivalent voltage drop characteristics in circuit operation.

Q: Why is the operating temperature range different?

A: The MBR1535CTG operates to 175°C junction temperature versus 150°C for the MBR1530CT. This extended range is a characteristic of the onsemi device and may provide additional thermal margin in high-temperature applications.

Q: What does fast recovery ≤ 500ns specification mean?

A: This indicates the diode switching speed, with recovery time not exceeding 500 nanoseconds for currents greater than 200 mA. Both parts meet this identical specification, ensuring equivalent switching performance in rectification circuits.

Q: Are both parts RoHS compliant?

A: Yes, both the MBR1530CT and MBR1535CTG are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under normal storage conditions without requiring special moisture-control packaging or handling procedures.
