Product details
Overview
MBRB10150CT from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO263AB (D2PAK) package, rated for 150V peak reverse voltage per leg, with max 0.89V forward voltage at 5A/25°C and 0.05mA reverse leakage at 150V/25°C - used as polarity protection and freewheeling diode in DC-DC converters and industrial power supplies.
For engineers reviewing the MBRB10150CT datasheet, MBRB10150CT pinout, MBRB10150CT application, or MBRB10150CT equivalent, key selection criteria include per-leg 5A average current rating, 100A non-repetitive surge capability, thermal resistance of 5°C/W junction-to-case, AEC-Q101 qualification, and RoHS-compliant matte tin terminations.
Technical Context
This dual Schottky rectifier integrates two independent 150V/5A legs sharing a common cathode terminal, enabling synchronous rectification or dual-rail output rectification in compact high-efficiency power stages. Its guard ring die construction provides transient overvoltage immunity, while low VF minimizes conduction loss in 12V–48V input systems.
Designed for surface-mount operation on 2-inch aluminum PCBs, it delivers 10A total output with thermal resistance of 5°C/W (junction-to-case) and 20°C/W (junction-to-ambient), supporting continuous operation up to +175°C junction temperature under proper heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM (Per Leg) | 150 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe operating range in flyback or buck converter freewheel paths. |
| IO (Per Leg) | 5 A - Average rectified forward current per leg at TA = +25°C; derates to ~3.5A at +100°C ambient per Figure 4. |
| VF (Max) | 0.89 V @ 5A, +25°C - Low forward drop reduces power loss (≤4.45W per leg at full load), critical for thermal management in enclosed power modules. |
| IFSM | 100 A - Non-repetitive 8.3ms half-sine surge rating; withstands inrush currents during hot-plug or capacitor charging events. |
| IR (Max) | 0.05 mA @ 150V, +25°C - Ultra-low reverse leakage preserves efficiency in high-impedance bias networks and battery-isolated circuits. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting; supports >8W dissipation with ≤40°C case-to-ambient delta. |
| AEC-Q101 | Qualified - Meets automotive-grade reliability standards for temperature cycling, HTRB, and ESD, suitable for under-hood industrial controls. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, 3-terminal molded plastic case with exposed copper drain tab for thermal and electrical connection. Weight: 1.6 g. UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode terminal | Connects to input/high-side switching node; carries full forward current of first rectifier leg. |
| Pin 2 (Cathode) | Common cathode | Shared output node for both legs; must be routed to low-impedance ground plane or output rail for minimal voltage bounce. |
| Pin 3 (Anode B) | Second anode terminal | Connects to second input path or complementary switch; enables dual-output or interleaved rectification topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient immunity (IEC 61000-4-2 Level 4 compatible), reducing need for external TVS in cost-sensitive 24V PLC I/O modules. |
| Low VF (0.81–0.89 V) | Reduces conduction loss by ≥30% vs. standard silicon rectifiers at 5A, directly improving 12V/48V SMPS efficiency by 0.8–1.2%. |
| TO263AB thermal performance | 5°C/W RθJC enables 8W+ dissipation with minimal heatsink area - ideal for space-constrained DIN-rail power supplies. |
| AEC-Q101 qualification | Validated for 1000h HTOL, -55°C to +175°C temp cycling, and 1000-cycle solderability - meets Tier-2 automotive body electronics requirements. |
Applications
| DC-DC Converter Output Rectification | Industrial Motor Drive Freewheeling |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in isolated 48V-to-12V buck-derived converters for telecom shelf power. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing MOSFETs in low-voltage, high-current outputs where gate drive complexity is undesirable. Use Value: Eliminates gate driver ICs and timing control, reducing BOM count by 3–5 components while maintaining <92% efficiency at 20A load. |
Use Scenario: Flyback diode across 24V DC solenoid valves and brushed motor windings in factory automation controllers. IC Role / Device Role / Timing Role: Recirculating diode clamping inductive kickback during PWM turn-off transitions. Use Value: 100A IFSM rating safely absorbs 50A–80A transient spikes without degradation, extending relay and contactor life. |
| Redundant Power Supply OR-ing | 12V Automotive Accessory Rail Protection |
|
Use Scenario: Diode-OR configuration combining two 28V DC inputs in avionics power distribution units. IC Role / Device Role / Timing Role: Polarity protection and source selection element ensuring uninterrupted supply during input switchover. Use Value: Common-cathode topology simplifies layout with single output trace; 0.05mA IR prevents cross-conduction leakage between sources. |
Use Scenario: Reverse-polarity protection at 12V accessory fuse box inputs in commercial vehicles. IC Role / Device Role / Timing Role: Input protection diode preventing damage from battery misconnection during service. Use Value: 150V VRRM exceeds ISO 7637-2 pulse 5a (120V) requirement; AEC-Q101 qualification ensures reliability in under-hood environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10BQ015 | Same 150V/5A per leg, but TO220AC package; RθJA = 35°C/W vs. 20°C/W for MBRB10150CT. | Requires through-hole mounting and larger heatsink; unsuitable for high-density SMT designs. | Select when legacy through-hole assembly is mandated or when higher single-leg surge rating (120A IFSM) is required. |
| ON Semiconductor MBR10150CT | Identical electrical specs and TO263AB footprint, but not AEC-Q101 qualified; IR = 0.1mA max at 150V/25°C. | Lacks automotive reliability validation; reverse leakage is double that of MBRB10150CT. | Acceptable for commercial-grade power supplies where AEC-Q101 is not required and leakage sensitivity is low. |
Compared with VS-10BQ015 and MBR10150CT, the MBRB10150CT uniquely combines AEC-Q101 qualification, ultra-low IR, and optimized SMT thermal performance - making it the preferred choice for space-constrained, high-reliability industrial and automotive auxiliary power rails.

FAQ
Is MBRB10150CT suitable for use in automotive under-hood applications?
Yes. The device is AEC-Q101 qualified and rated for operation from –55°C to +175°C junction temperature. Its guard ring die structure, 100A surge rating, and RoHS-compliant matte tin terminations meet requirements for engine control modules, body control units, and HVAC blower drivers where thermal and transient stress are severe.
What is the recommended PCB pad layout for TO263AB (D2PAK) mounting?
Diodes recommends a minimum 10.41 mm × 7.01 mm copper pour connected to Pin 2 (cathode) for thermal relief, with 1.10 mm solder mask opening and 5.08 mm center-to-center spacing between mounting holes. Use ≥2 oz copper and thermal vias beneath the tab to achieve RθJA ≤20°C/W on 2-inch Al board.
How does the dual common-cathode configuration affect circuit layout?
The shared cathode (Pin 2) serves as the unified output node for both anode legs, simplifying routing in dual-output or OR-ing configurations. It requires low-inductance, wide-trace connection to ground or output rail - improper layout causes voltage overshoot during fast switching, especially above 100 kHz.
Can MBRB10150CT replace a single 10A Schottky in a 12V input system?
No - it is a dual 5A-per-leg device, not a single 10A device. Each leg is rated for 5A average current. Using only one leg yields 5A capacity; paralleling both anodes is unsafe due to mismatched VF and thermal coupling. For 10A single-leg needs, select MBR20150CT or equivalent.
