MBRB880-TP Equivalent & Substitute Parts

Part Overview

The MBRB880-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 80 V DC reverse voltage and 8 A average rectified current in a surface mount D2PAK package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. The fast recovery characteristic (≤500ns, >200mA) and low forward voltage drop make this diode suitable for high-frequency switching applications requiring efficient rectification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB880-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must have a DC reverse voltage rating equal to or greater than 80 V to maintain circuit protection and reliability margins.

Current Rating Compatibility: The substitute part must have an average rectified current rating equal to or greater than 8 A to handle the design load without thermal stress.

Forward Voltage Characteristics: Forward voltage drop at rated current must remain within acceptable limits to preserve circuit efficiency and thermal performance.

Recovery Speed: Fast recovery characteristic (≤500ns, >200mA) must be maintained to ensure switching performance in high-frequency applications.

Reverse Leakage Current: Leakage current specifications must be compatible with circuit requirements to prevent unwanted bias conditions.

Package Compatibility: The substitute must use the same D2PAK surface mount package to ensure mechanical and thermal interface compatibility with existing PCB layouts.

Operating Temperature Range: The substitute must support the required junction temperature range for the application environment.

The MBRB10100-TP meets all substitution criteria with equal or superior electrical ratings and maintains identical package specifications.

Engineering Selection Recommendations

Product Status Consideration: The MBRB880-TP is classified as obsolete, while the MBRB10100-TP is active. Selection of the active substitute part ensures long-term availability and supply chain continuity.

Compliance and Certification: The MBRB10100-TP carries RoHS3 compliance and Moisture Sensitivity Level (MSL) 1 (Unlimited) ratings, providing superior environmental and handling specifications compared to the obsolete MBRB880-TP.

Electrical Performance: The MBRB10100-TP provides higher voltage and current ratings (100 V, 10 A) while maintaining identical forward voltage characteristics and recovery speed. This superior rating provides additional design margin without performance degradation.

Thermal Considerations: The MBRB10100-TP operates to a maximum junction temperature of 125°C, compared to 150°C for the MBRB880-TP. Applications requiring operation above 125°C require thermal analysis to confirm compatibility.

Package and Mechanical Compatibility: Both parts use identical D2PAK surface mount packaging, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the MBRB10100-TP directly replace the MBRB880-TP in existing designs?

A: Yes, the MBRB10100-TP is a direct substitute. Both parts use identical D2PAK surface mount packages and maintain equivalent electrical characteristics for forward voltage and recovery speed. The substitute part has higher voltage and current ratings, providing additional design margin.

Q: What is the primary reason for substitution?

A: The MBRB880-TP is obsolete. The MBRB10100-TP is an active product from the same manufacturer with superior availability and compliance certifications.

Q: Are there any thermal limitations when using the MBRB10100-TP?

A: The MBRB10100-TP has a maximum junction temperature of 125°C, compared to 150°C for the MBRB880-TP. Applications designed to operate above 125°C require thermal analysis to confirm the substitute part remains within safe operating limits.

Q: Do the forward voltage characteristics differ between these parts?

A: No. Both parts specify 850 mV maximum forward voltage at their respective rated currents (8 A and 10 A). Circuit efficiency and thermal performance remain equivalent.

Q: Is the D2PAK package identical for both parts?

A: Yes. Both the MBRB880-TP and MBRB10100-TP use the TO-263-3 D2PAK (2 Leads + Tab) package. No PCB layout modifications are required for substitution.

Q: What compliance advantages does the MBRB10100-TP offer?

A: The MBRB10100-TP is RoHS3 compliant and carries Moisture Sensitivity Level 1 (Unlimited), indicating superior environmental compliance and handling flexibility compared to the obsolete MBRB880-TP.

Q: Are reverse leakage current specifications equivalent?

A: Yes. Both parts specify 500 µA maximum reverse leakage current at their respective rated voltages (80 V and 100 V). Circuit bias conditions remain equivalent.

Q: Can the MBRB10100-TP be used in applications requiring the full 80 V rating?
