Product details
Overview
MBR15150CT from Taiwan Semiconductor is a 15A, 150V dual-die Schottky barrier rectifier in TO-220AB package, featuring 1.05V forward voltage at 7.5A/25°C, 5mA reverse leakage at 150V/125°C, and 150A surge capability - deployed in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR15150CT datasheet, MBR15150CT pinout, MBR15150CT application, or MBR15150CT equivalent, key selection criteria include its 150V VRRM rating, dual-common-cathode configuration, TO-220AB thermal resistance (RθJC = 1.5°C/W), and AEC-Q101 qualification availability for automotive-grade reliability validation.
Technical Context
The MBR15150CT integrates two independent Schottky diodes in a common-cathode configuration within a single TO-220AB thermally optimized package, enabling synchronous rectification or dual-output DC-DC topologies. Its 150V blocking voltage supports 48V–60V bus systems with margin, while guard ring design enhances transient overvoltage immunity.
Thermal performance is defined by RθJA = 10°C/W (unmounted) and RθJC = 1.5°C/W, allowing sustained 15A conduction at TJ ≤ 150°C when properly heatsinked. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance.
Key Specifications

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-15BQ150PBF | Same 15A/150V rating, TO-220AC package (non-insulated), VF = 1.02V @ 7.5A/25°C, RθJC = 1.7°C/W | Lacks guard ring; lower dv/dt rating (5,000 V/μs); not AEC-Q101 qualified in standard version | Preferred where cost sensitivity outweighs automotive qualification or extreme dv/dt immunity needs |
| ON Semiconductor MBR15150CTG | Identical electrical specs and TO-220AB package; same VF, IR, and thermal resistance; RoHS/halogen-free compliant | Manufactured by ON Semi; pinout and footprint identical; no functional difference in circuit behavior | Drop-in alternative with identical sourcing path for supply chain diversification |
Compared with MBR15150CT, VS-15BQ150PBF trades dv/dt robustness and qualification for lower cost and broader distribution, while MBR15150CTG offers identical performance with alternate manufacturing origin - both support same thermal and layout constraints but differ in reliability validation scope and sourcing continuity.

FAQ
What is the maximum junction temperature rating for the MBR15150CT?
The MBR15150CT has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating enables use in high-ambient environments such as enclosed industrial power supplies or under-hood automotive systems when paired with appropriate heatsinking. Thermal derating must follow the forward current curve in Figure 1 of the official datasheet.
Does the MBR15150CT have AEC-Q101 qualification?
The base MBR15150CT is not AEC-Q101 qualified; however, the variant MBR15150CTH - identical in all electrical and mechanical specifications - is fully AEC-Q101 qualified for automotive applications. Customers requiring automotive-grade reliability must specify the "H" suffix ordering code to receive the qualified version.
What is the forward voltage drop of the MBR15150CT at full rated current?
The MBR15150CT does not specify forward voltage at 15A/25°C in the provided datasheet; only VF = 1.05V is guaranteed at 7.5A/25°C. At higher currents and elevated temperatures, VF increases - e.g., typical VF at 7.5A/125°C is 0.92V. Designers should consult Figure 4 (Typical Forward Characteristics) for interpolation across operating conditions.
How is the pinout configured for the dual-diode structure in the MBR15150CT?
The MBR15150CT uses a common-cathode configuration: Pin 1 is Anode 1, Pin 2 (center tab) is the shared Cathode, and Pin 3 is Anode 2. This arrangement supports dual-output rectification or interleaved topologies without external cathode tying. The TO-220AB case is electrically insulated, enabling direct heatsink mounting without isolation hardware.
What is the reverse leakage current specification for the MBR15150CT at elevated temperature?
At rated reverse voltage (150V) and junction temperature of 125°C, the MBR15150CT specifies a maximum reverse leakage current (IR) of 5 mA per diode. This value is critical for standby power budgeting in high-efficiency systems and influences thermal runaway risk in parallel configurations - designers should verify thermal coupling and derating margins accordingly.
