Part Overview

The MBRF10150CT-JT is a Schottky diode array manufactured by Diodes Incorporated, configured as 1 pair common cathode with 150 V reverse voltage rating and 5 A average rectified current per diode. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design and procurement requirements. The part features fast recovery characteristics (≤500 ns) and automotive-grade qualification under AEC-Q101 standard, with through-hole TO-220-3 mounting in an isolated tab package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF10150CT-JT is determined by the following critical parameters: diode configuration (1 pair common cathode), technology (Schottky), reverse voltage rating (150 V), and mounting type (through-hole TO-220-3). Current rating serves as a secondary criterion; substitute parts with equal or higher current capacity are functionally compatible in applications where the original 5 A rating is required.

The identified substitute parts are grouped into two categories:

Category 1: Direct Current Rating Match (5 A) MBR10150CTF-G1 maintains the original 5 A current specification with identical reverse voltage and diode configuration. This part transitions from obsolete to active product status.

Category 2: Higher Current Rating (15 A, 20 A, 25 A) DSTF30150C, DSTF40150C, and MBRF25150CTHC0G provide increased current capacity while maintaining the 150 V reverse voltage and common cathode configuration. These parts are suitable for applications requiring higher current handling or where design margin is required.

All substitute parts maintain Schottky technology, fast recovery speed characteristics, and through-hole mounting in TO-220-3 packages with isolated tabs. RoHS3 compliance is consistent across all options.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (5 A Current Rating): MBR10150CTF-G1 is the primary substitute for MBRF10150CT-JT. Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications at the 5 A operating point. MBR10150CTF-G1 holds active product status, ensuring long-term availability and supply chain continuity. The forward voltage differential (920 mV versus 890 mV at 5 A) is within typical manufacturing tolerance ranges for Schottky diodes. The primary distinction is packaging format: MBR10150CTF-G1 uses standard TO-220-3 without isolated tab, whereas the original features isolated tab configuration. PCB layout verification is required to confirm mechanical compatibility.

For Automotive Applications with AEC-Q101 Requirement: MBRF25150CTHC0G is the only substitute maintaining both automotive grade classification and AEC-Q101 qualification. This part provides 25 A current capacity with superior forward voltage characteristics (1.02 V @ 25 A) compared to the original 5 A specification. Automotive applications requiring continued AEC-Q101 compliance should prioritize this option.

For Higher Current Capacity Applications: DSTF30150C (15 A) and DSTF40150C (20 A) manufactured by Littelfuse Inc. provide intermediate and elevated current ratings while maintaining 150 V reverse voltage and common cathode configuration. These parts are suitable for applications where the original 5 A rating is insufficient or where design margin enhancement is required. Both parts maintain active product status and ROHS3 compliance.

All substitute parts maintain fast recovery Schottky technology and through-hole mounting compatibility with TO-220-3 footprints.

Frequently Asked Questions (FAQ)

Q: Can MBR10150CTF-G1 be used as a direct replacement for MBRF10150CT-JT?

A: MBR10150CTF-G1 is electrically compatible as a direct replacement. Both parts share identical diode configuration (1 pair common cathode), reverse voltage rating (150 V), and current capacity (5 A). The primary difference is package configuration: MBR10150CTF-G1 uses standard TO-220-3 without isolated tab, while MBRF10150CT-JT includes isolated tab. PCB layout must be verified to confirm mechanical fit and thermal management compatibility.

Q: What is the difference between parts with 5 A, 15 A, 20 A, and 25 A ratings?

A: Current rating indicates the maximum average rectified current per diode. Parts with higher current ratings (15 A, 20 A, 25 A) can handle greater current loads than the original 5 A specification. These higher-rated parts are suitable for applications requiring increased current capacity or where design margin is required. Forward voltage increases with current rating due to semiconductor physics; higher current parts exhibit higher forward voltage drops at their rated currents.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute parts (MBR10150CTF-G1, DSTF30150C, DSTF40150C, and MBRF25150CTHC0G) maintain ROHS3 compliance, consistent with the original MBRF10150CT-JT specification.

Q: Which substitute part should be selected for automotive applications?

A: MBRF25150CTHC0G is the recommended substitute for automotive applications. This part maintains automotive grade classification and AEC-Q101 qualification, matching the original MBRF10150CT-JT requirements. MBRF25150CTHC0G provides 25 A current capacity with active product status and long-term availability.

Q: What is the significance of the isolated tab package configuration?

A: The isolated tab (ITO-220AB) package provides electrical isolation between the mounting tab and the diode cathode, enabling direct mounting to a common heat sink without electrical isolation hardware. Standard TO-220-3 packages (TO-220F-3) require additional isolation if the tab must be electrically isolated from the cathode. PCB design and thermal management requirements determine whether isolated tab configuration is necessary.

Q: Can higher-rated parts (15 A, 20 A, 25 A) be used in applications designed for 5 A?

A: Yes, higher-rated parts are functionally compatible in applications designed for 5 A operation. The higher current rating provides design margin and does not degrade performance at lower current levels. Forward voltage characteristics differ at rated current; verify that thermal management and circuit design accommodate the specific forward voltage of the selected substitute part.

Q: What is the operating temperature range difference between substitute parts?

A: MBRF10150CT-JT and MBR10150CTF-G1 support -55°C to 175°C junction temperature range. DSTF30150C, DSTF40150C, and MBRF25150CTHC0G are rated to -55°C to 150°C maximum junction temperature. Applications requiring operation above 150°C junction temperature must use MBR10150CTF-G1 or the original part if still available.

Q: Are there differences in reverse leakage current between substitute parts?

A: Yes, reverse leakage current varies among substitute parts. MBRF10150CT-JT specifies 50 µA @ 150 V, while MBR10150CTF-G1 and MBRF25150CTHC0G specify 100 µA @ 150 V. DSTF30150C and DSTF40150C specify 200 µA and 250 µA respectively. Applications sensitive to leakage current should prioritize parts with lower leakage specifications.
