MBR500150CT Equivalent & Substitute Parts

Part Overview

The MBR500150CT is a Schottky diode module manufactured by GeneSiC Semiconductor, configured as a 1 Pair Common Cathode array with 150V reverse voltage rating and 250A average rectified current per diode. The device features a Twin Tower chassis mount package and is classified as obsolete. Due to its obsolete product status, equivalent and substitute parts from the same manufacturer series are available to maintain design continuity and ensure supply chain availability for applications requiring Schottky rectifier diode arrays with comparable electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the MBR500150CT is determined by strict equivalence across the following critical parameters:

Fixed Substitution Criteria:

• Manufacturer: GeneSiC Semiconductor
• Technology: Schottky
• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 150 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 3 mA @ 150 V
• Operating Temperature - Junction: -55°C ~ 150°C
• Mounting Type: Chassis Mount
• Package / Case: Twin Tower
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Current - Average Rectified (Io) (per Diode): Substitute parts may have equal or higher current ratings

The MBR600150CT and MBR400150CT are qualified substitutes because they maintain identical electrical characteristics across all fixed parameters while offering alternative current ratings. The MBR600150CT provides increased current capacity (300A), while the MBR400150CT provides reduced current capacity (200A), both suitable for applications where the original 250A specification can be accommodated by higher or lower rated alternatives.

Engineering Selection Recommendations

MBR600150CT (Direct Substitute - Recommended for New Designs)

The MBR600150CT is an active product with identical electrical and mechanical specifications to the MBR500150CT, with the exception of increased current capacity (300A versus 250A). This part is suitable for direct replacement in applications where the original 250A specification is within the 300A capability. The active product status ensures long-term availability and supply chain continuity. RoHS compliance and MSL rating are maintained.

MBR400150CT (Similar Substitute - Current-Limited Applications)

The MBR400150CT is an active product suitable for applications where the average rectified current requirement does not exceed 200A. This part maintains all other electrical and mechanical characteristics of the MBR500150CT. The active product status and RoHS compliance support ongoing availability. Selection of this part is appropriate only when circuit design permits operation within the 200A current limit.

Both substitute parts maintain compliance certifications (RoHS, MSL 1) and are manufactured by GeneSiC Semiconductor, ensuring consistency with the original design ecosystem.

Frequently Asked Questions (FAQ)

Q: Can the MBR600150CT directly replace the MBR500150CT in all applications?

A: The MBR600150CT maintains identical electrical and mechanical specifications to the MBR500150CT with the exception of current rating (300A versus 250A). Direct replacement is permissible in applications where the circuit operates at or below 250A average rectified current. The higher current rating of the MBR600150CT does not create incompatibility with designs specified for 250A operation.

Q: What is the primary difference between the MBR500150CT and MBR400150CT?

A: The primary difference is the average rectified current rating per diode: MBR500150CT is rated for 250A, while MBR400150CT is rated for 200A. All other electrical parameters, including reverse voltage (150V), forward voltage (880mV), leakage current (3mA), and thermal characteristics remain identical. The MBR400150CT is suitable only for applications where peak and average current demands do not exceed 200A.

Q: Are the Twin Tower package dimensions identical across all three parts?

A: All three parts (MBR500150CT, MBR600150CT, and MBR400150CT) utilize the Twin Tower chassis mount package. Mechanical compatibility for mounting and thermal interface is maintained across all three variants.

Q: Why is the MBR500150CT classified as obsolete?

A: The MBR500150CT is listed as obsolete by the manufacturer. The MBR600150CT and MBR400150CT are active products that provide equivalent functionality with current rating variations. For new designs and ongoing production, selection of an active product variant is recommended to ensure supply chain continuity.

Q: Do all substitute parts maintain RoHS compliance?

A: Yes. The MBR500150CT, MBR600150CT, and MBR400150CT are all RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is maintained across all variants.

Q: What is the significance of the 880mV forward voltage specification?

A: The forward voltage specification of 880mV is maintained across all three parts at their respective rated currents (250A, 300A, and 200A). This consistency ensures that thermal and electrical performance characteristics remain predictable during substitution, provided the application operates within the current rating of the selected part.
