MBR30L60CT Equivalent & Substitute Parts

Part Overview

The MBR30L60CT is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, configured as a 1 Pair Common Cathode with a maximum reverse voltage of 60 V and average rectified current of 30 A per diode. The device is packaged in TO-220-3 through-hole configuration and is classified as Active product status with full RoHS3 compliance.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design specifications permit operation within the electrical and mechanical parameters of alternative devices. Substitute parts must maintain compatibility with the TO-220-3 package footprint and satisfy the core electrical requirements of 60 V reverse voltage and Schottky technology classification.

Substitute Part Grouping Explanation

Substitution of the MBR30L60CT is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Voltage - DC Reverse (Vr) (Max): 60 V minimum
Mounting Type: Through Hole
Package / Case: TO-220-3

Current Rating Considerations: Substitute parts are grouped by average rectified current (Io) per diode. The MBR30L60CT operates at 30 A. Substitutes with equal or greater current ratings (30 A or higher) provide direct replacement capability. Substitutes with lower current ratings (7.5 A, 10 A, 15 A, 20 A) are classified as similar parts suitable only for applications where the lower current specification is acceptable.

Electrical Performance Parameters: Forward voltage (Vf), reverse leakage current, and operating temperature range are secondary selection criteria. These parameters vary among substitutes but do not prevent substitution when primary criteria are met.

Product Status and Compliance: All substitute parts listed maintain RoHS3 compliance and ROHS3 Compliant status. One substitute (MBR2060CT-LJ) carries Obsolete product status and requires verification of long-term availability.

Engineering Selection Recommendations

Direct Replacement (Equal Current Rating):

MBR3060CT is the primary direct substitute for MBR30L60CT. Both devices are manufactured by Taiwan Semiconductor Corporation, share identical 30 A current ratings, and maintain Active product status with RoHS3 compliance. The MBR3060CT exhibits higher forward voltage (770 mV versus 600 mV at 15 A) and lower reverse leakage current (200 µA versus 480 µA at 60 V). These electrical differences do not prevent substitution in applications where the MBR30L60CT operates within specification.

Reduced Current Rating Substitutes (Active Status):

MBR40L60CTG (20 A), MBR30H60CT-E3/45 (15 A), VT30L60C-E3/4W (15 A), and MBR1560CT-E3/45 (7.5 A) are classified as similar parts with lower current ratings. These devices are suitable only for applications where the circuit current demand does not exceed the substitute part's Io specification. All four maintain Active product status and RoHS3 compliance.

MBR30H60CT-E3/45 and MBR1560CT-E3/45 offer extended operating temperature ranges (-65°C to 175°C) compared to the MBR30L60CT (-55°C to 150°C), providing thermal margin in high-temperature applications.

Obsolete Status Consideration:

MBR2060CT-LJ carries Obsolete product status and is not recommended for new designs or long-term production applications. This part is listed for reference only in legacy system maintenance scenarios.

Frequently Asked Questions (FAQ)

Q: Can MBR3060CT replace MBR30L60CT in all applications?

A: MBR3060CT is a direct electrical substitute with identical 30 A current rating and 60 V reverse voltage specification. Both devices use Schottky technology, share TO-220-3 packaging, and maintain -55°C to 150°C operating temperature ranges. The MBR3060CT exhibits different forward voltage and reverse leakage characteristics but operates within the same functional envelope. Substitution is valid when circuit design does not depend on the specific forward voltage or leakage values of the MBR30L60CT.

Q: What is the difference between direct substitutes and similar parts?

A: Direct substitutes maintain the same average rectified current rating (30 A). Similar parts have lower current ratings (7.5 A to 20 A) and are suitable only when the application circuit operates below the substitute part's current specification. Using a similar part in a circuit designed for 30 A operation will result in device failure or thermal stress.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed carry RoHS3 Compliant status. MBR2060CT-LJ carries REACH Affected status, while all other substitutes are REACH Unaffected. Compliance verification is required for applications subject to specific regulatory frameworks.

Q: Can I use MBR30H60CT-E3/45 or MBR1560CT-E3/45 in high-temperature applications?

A: MBR30H60CT-E3/45 and MBR1560CT-E3/45 support operating temperature ranges of -65°C to 175°C, compared to -55°C to 150°C for the MBR30L60CT. These parts provide thermal margin in elevated-temperature environments. However, MBR30H60CT-E3/45 is rated at 15 A and MBR1560CT-E3/45 at 7.5 A, so current rating compatibility must be verified before selection.

Q: Is the TO-220-3 package footprint identical across all substitute parts?

A: All substitute parts use TO-220-3 through-hole packaging. Physical footprint compatibility is maintained across all listed devices. Mounting and thermal interface considerations remain consistent with the original MBR30L60CT design.

Q: Why does MBR2060CT-LJ show Obsolete status?

A: MBR2060CT-LJ is classified as Obsolete by the manufacturer. This designation indicates the part is no longer in active production. Existing inventory may be available, but long-term supply cannot be guaranteed. This part is listed for reference in legacy system support only and is not recommended for new designs.

Q: What forward voltage differences should I consider when selecting a substitute?

A: Forward voltage varies among substitutes: MBR30L60CT operates at 600 mV @ 15 A, while MBR3060CT operates at 770 mV @ 15 A. These differences affect power dissipation and thermal performance. In low-current applications, forward voltage variation is less critical. In high-current or thermally constrained designs, forward voltage differences must be evaluated against circuit power budget requirements.
