Product details
Overview
MBRB10150CT-13 from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO263AB (D2PAK) package, rated for 150V peak reverse voltage, with max 0.89V forward voltage at 5A/25°C and 0.05mA reverse leakage at 150V/25°C. It serves as polarity protection and freewheeling diode in DC-DC converters and industrial power supplies.
For engineers reviewing the MBRB10150CT-13 datasheet, MBRB10150CT-13 pinout, MBRB10150CT-13 application, or MBRB10150CT-13 equivalent, key selection criteria include its dual-leg thermal resistance (RθJC = 5°C/W), AEC-Q101 qualification, RoHS-compliant matte tin finish, and 100A non-repetitive surge rating for high-reliability power conversion designs.
Technical Context
This dual Schottky rectifier integrates two independent 5A legs sharing a common cathode terminal, enabling synchronous rectification or dual-output DC-DC topologies. Its guard ring die construction provides transient overvoltage protection, while low VF minimizes conduction losses in high-frequency switching applications up to 1 MHz.
The device operates across -55°C to +175°C junction temperature range and supports 10000 V/μs voltage slew rate, making it suitable for fast-switching buck converters and motor drive recirculation paths where thermal management and EMI reduction are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR20150CT | 20A total (10A/leg), same VRRM, higher VF (0.92V), RθJC = 4.5°C/W | Higher current handling but larger footprint (TO-220AC); less suitable for space-constrained D2PAK layouts | Select when system requires >10A per leg and board space allows through-hole mounting |
| ON Semiconductor MBR10150CT | Same ratings and TO263AB package, but not AEC-Q101 qualified; IR max = 0.1mA at 150V/25°C | Lacks automotive qualification; higher leakage may impact long-term battery retention in always-on modules | Prefer for cost-sensitive commercial power supplies where AEC-Q101 is not mandated |
Compared with VS-MBR20150CT and MBR10150CT, MBRB10150CT-13 uniquely balances AEC-Q101 compliance, low leakage, and D2PAK thermal performance-making it optimal for space-limited, high-reliability industrial and automotive power interfaces.

FAQ
What is the maximum junction temperature for MBRB10150CT-13?
The absolute maximum junction temperature is +175°C, with continuous operation supported from -55°C to +175°C. Derating curves in the datasheet show usable average forward current drops linearly above +25°C ambient, reaching 0A at +175°C case temperature when mounted on a 2-inch aluminum board per test condition.
Is MBRB10150CT-13 suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a synchronous MOSFET driver or controller. However, its low VF and fast recovery make it a preferred alternative to active synchronous designs where gate drive complexity, cost, or layout constraints prohibit MOSFET implementation.
How does the "Type TH" and "Type BR" suffix affect MBRB10150CT-13?
"Type TH" and "Type BR" denote minor mechanical variants of the TO263AB (D2PAK) package-differing in leadframe thickness, mold compound profile, and pad layout tolerances-but electrically identical and fully interchangeable in circuit design and thermal performance.
Does MBRB10150CT-13 require a heatsink in typical applications?
Not necessarily: with RθJC = 5°C/W and RθJA = 20°C/W (on 2-inch Al board), it dissipates up to ~8W per leg at +100°C case temperature. For ≤5A continuous operation at ≤60°C ambient, a 200 mm² copper pour under the cathode pad suffices; larger heatsinks are needed only for sustained >8W dissipation or high ambient temperatures.
