MBR12150LPS-TP Equivalent & Substitute Parts

Part Overview

The MBR12150LPS-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 150 V DC reverse voltage and 12 A average rectified current in a surface mount TO-277-3 package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with modified ratings suitable for the same application circuit topology.

Substitute Part Grouping Explanation

Substitution of the MBR12150LPS-TP is determined by the following critical parameters: reverse voltage rating (150 V), package type (TO-277-3 surface mount), technology (Schottky), and thermal operating range (-55°C to 150°C junction temperature).

Parametric Equivalent Classification: FSV12150V maintains identical electrical specifications (150 V, 12 A, 820 mV forward voltage, 30 µA reverse leakage) and package configuration, qualifying as a parametric equivalent despite manufacturer change from Micro Commercial Co to onsemi.

Direct Substitute Classification: MBR15U150-TP provides functional substitution with increased current rating (15 A versus 12 A) while maintaining the same 150 V reverse voltage, TO-277 package family, and operating temperature range. The elevated forward voltage (840 mV @ 15 A) and reverse leakage (100 µA @ 150 V) remain within acceptable tolerance for applications designed for the original 12 A specification.

All substitute parts comply with ROHS3 requirements and maintain fast recovery Schottky characteristics.

Engineering Selection Recommendations

For Obsolete Part Replacement: The MBR15U150-TP is the primary selection for new procurement and design updates. This part maintains active product status with Micro Commercial Co, ensuring long-term availability and supply chain stability. The increased current rating (15 A) provides design margin for applications originally specified at 12 A, with thermal and voltage characteristics remaining identical to the original component.

For Parametric Equivalence: The FSV12150V from onsemi provides exact electrical and mechanical equivalence to the MBR12150LPS-TP. However, this part carries "Not For New Designs" status, limiting its application to legacy system maintenance or repair scenarios where original specifications must be preserved without modification.

Compliance Considerations: All three parts maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), ensuring compatibility with standard surface mount assembly processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MBR15U150-TP directly replace MBR12150LPS-TP in existing designs?

A: Yes. The MBR15U150-TP maintains identical reverse voltage (150 V), package type (TO-277 surface mount), operating temperature range (-55°C to 150°C), and Schottky technology. The increased current rating (15 A versus 12 A) and slightly elevated forward voltage (840 mV @ 15 A versus 820 mV @ 12 A) are compatible with circuits designed for the original 12 A specification.

Q: What is the difference between FSV12150V and MBR15U150-TP?

A: FSV12150V is a parametric equivalent manufactured by onsemi with identical electrical specifications (150 V, 12 A, 820 mV forward voltage). MBR15U150-TP is a direct substitute from Micro Commercial Co with increased current capacity (15 A). FSV12150V carries "Not For New Designs" status, while MBR15U150-TP is active and recommended for new applications.

Q: Are package dimensions identical across all three parts?

A: All three parts use the TO-277 3-PowerDFN package family with surface mount configuration. The supplier device package designation differs slightly (TO-277-3 for MBR12150LPS-TP and FSV12150V; TO-277 for MBR15U150-TP), but physical footprint and thermal characteristics remain compatible for PCB assembly.

Q: What is the impact of increased reverse leakage in MBR15U150-TP?

A: The MBR15U150-TP exhibits 100 µA reverse leakage at 150 V compared to 30 µA for the original part. This represents a 70 µA increase in standby current. For applications with strict leakage requirements, circuit-level analysis is necessary to confirm acceptability within power budget constraints.

Q: Which part should be selected for new designs?

A: MBR15U150-TP is the recommended selection for new designs. This part maintains active product status, ensuring availability and supply chain continuity. The higher current rating provides design margin without compromising voltage or thermal specifications.
