MBRB1050-TP Equivalent & Substitute Parts

Part Overview

The MBRB1050-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 10 A average rectified current in a surface mount D2PAK package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity. The fast recovery characteristic (≤500ns, >200mA) and low forward voltage drop make this diode suitable for high-frequency switching and power conversion applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1050-TP is determined by the following critical parameters:

Mandatory Matching Criteria:

• Technology: Schottky (fast recovery rectifier)
• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab)
• Current - Average Rectified (Io): 10 A
• Operating Temperature Range: -65°C to 150°C (minimum)
• Speed: Fast Recovery ≤500ns, >200mA (Io)

Allowable Variation:

• Voltage - DC Reverse (Vr) (Max): Equal to or greater than 50 V (higher voltage rating provides backward compatibility in applications not requiring the exact 50 V specification)

The MBRB1060-TP qualifies as a direct substitute because it maintains identical current rating, package, mounting type, speed characteristics, and temperature range while providing an elevated voltage rating of 60 V, which is compatible with circuits designed for the 50 V part.

Engineering Selection Recommendations

The MBRB1060-TP is the qualified substitute for the obsolete MBRB1050-TP. Selection is based on the following factors:

Product Status: The MBRB1050-TP is classified as obsolete, while the MBRB1060-TP maintains active status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.10.0080), confirming equivalent regulatory standing.

Electrical Compatibility: The MBRB1060-TP maintains all critical electrical parameters—current rating, speed characteristics, reverse leakage, and temperature range—while providing a higher voltage rating. This elevated voltage specification (60 V versus 50 V) is compatible with applications designed for the original part, as the substitute can withstand higher reverse bias conditions without degradation.

Package and Mounting: Identical D2PAK surface mount packaging ensures direct PCB compatibility without layout modifications.

Use the MBRB1060-TP for new designs and obsolescence mitigation of existing MBRB1050-TP applications.

Frequently Asked Questions (FAQ)

Q: Can the MBRB1060-TP directly replace the MBRB1050-TP on existing PCBs?

A: Yes. Both parts use identical TO-263-3 D2PAK surface mount packaging with the same pinout and footprint. No PCB layout changes are required.

Q: Why does the substitute have a higher voltage rating (60 V vs. 50 V)?

A: The MBRB1060-TP is rated for 60 V maximum reverse voltage, compared to 50 V for the original part. This higher rating is compatible with 50 V applications because the substitute can withstand greater reverse bias stress. The circuit will operate within the substitute's voltage capability.

Q: Are the current ratings identical?

A: Yes. Both the MBRB1050-TP and MBRB1060-TP are rated for 10 A average rectified current, ensuring equivalent power handling capability.

Q: Do the parts have the same speed characteristics?

A: Yes. Both parts feature fast recovery characteristics of ≤500ns for currents >200mA (Io), making them suitable for identical high-frequency switching applications.

Q: What is the temperature operating range for both parts?

A: Both parts operate over a junction temperature range of -65°C to 150°C, providing identical thermal performance.

Q: Are there any compliance or regulatory differences between the parts?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.10.0080).

Q: Why is the MBRB1050-TP listed as obsolete?

A: The MBRB1050-TP has reached end-of-life status. The MBRB1060-TP is the active equivalent maintained by the manufacturer for ongoing supply and new designs.

Q: Can I use the MBRB1060-TP in reverse polarity applications?

A: No. Schottky rectifier diodes are polarized components. The MBRB1060-TP must be oriented with the cathode (marked end) toward the negative potential and the anode toward the positive potential, identical to the MBRB1050-TP.
