Product details
Overview
MBR30150CT from Taiwan Semiconductor is a 30A, 150V dual-die Schottky barrier rectifier in TO-220AB package, featuring 1.02V forward voltage at 30A/25°C and 5mA reverse leakage at 150V/125°C, used in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the MBR30150CT datasheet, MBR30150CT pinout, MBR30150CT application, or MBR30150CT equivalent, key selection criteria include VRRM=150V, IFSM=200A surge rating, RθJC=1.5°C/W thermal resistance, low VF at high temperature, and AEC-Q101 qualification availability.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 15A-rated dies in one TO-220AB housing, enabling synchronous or interleaved operation in center-tapped or dual-output topologies. Its guard ring structure provides overvoltage protection while maintaining fast recovery (dv/dt = 10,000 V/μs) and low junction capacitance.
The device operates across -55°C to +150°C junction range with 1.5°C/W junction-to-case thermal resistance specific to the 90–150V variants. Reverse leakage is tightly specified at 100µA @ 25°C and 5mA @ 125°C under rated 150V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating ceiling in high-voltage DC bus applications |
| IF(AV) | 30 A - Average forward current per device; supports continuous 30A conduction in thermally managed designs |
| VF @ 30A/25°C | 1.02 V - Forward voltage drop at full rated current; determines conduction loss and thermal load in power stage |

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-30CPH15 | Same TO-220AB package, 30A/150V, VF = 0.99V @ 30A/25°C, RθJC = 1.4°C/W, no AEC-Q101 option | Higher surge rating (250A), but lacks automotive-qualified variant | Preferred where maximum surge robustness is prioritized over automotive compliance |
| ON Semiconductor MBR30H150CT | Identical electrical specs and TO-220AB package; AEC-Q101 qualified as standard, VF = 1.03V @ 30A/25°C | Designed specifically for automotive systems; tighter IR screening at high temperature | Best choice when AEC-Q101 compliance is mandatory and supply chain diversification is needed |
Compared with MBR30150CT, VS-30CPH15 offers slightly better thermal resistance and surge margin but no automotive qualification, while MBR30H150CT delivers identical performance with guaranteed AEC-Q101 compliance-making it a drop-in alternative only when automotive use is required.

FAQ
What is the maximum junction temperature rating for MBR30150CT?
The MBR30150CT has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This rating allows operation in high-ambient environments such as enclosed industrial power supplies or telecom rectifier shelves. Derating curves confirm usable current capacity down to 15A at 125°C case temperature. Thermal design must respect the 1.5°C/W RθJC value to avoid exceeding TJ max under full 30A load.
Does MBR30150CT have AEC-Q101 qualification?
The base MBR30150CT is not AEC-Q101 qualified; however, the MBR30150CTH variant-identical in all electrical and mechanical specifications-is explicitly qualified per AEC-Q101. The "H" suffix denotes automotive-grade screening and test compliance. For automotive applications like onboard chargers or ADAS power modules, MBR30150CTH must be specified; MBR30150CT alone does not meet automotive reliability requirements.
What is the forward voltage of MBR30150CT at 30A and 125°C?
The forward voltage of MBR30150CT at 30A and 125°C is 0.98 V, as specified in the Electrical Specifications table under "Forward voltage per diode" conditions. This value reflects real-world conduction loss under elevated temperature stress and is critical for thermal modeling in high-ambient applications. It is 40 mV lower than the 1.02 V measured at 25°C, demonstrating favorable VF temperature coefficient for Schottky devices.
How is the pinout configured for MBR30150CT in TO-220AB package?
The MBR30150CT uses a three-pin TO-220AB configuration: Pin 1 is Anode 1, Pin 2 is the common cathode, and Pin 3 is Anode 2. This dual-anode/common-cathode arrangement supports center-tapped transformer outputs or interleaved rectification. Polarity is marked on the device body per TSC's standard marking diagram, and the cathode tab is electrically connected to Pin 2-not isolated.
What is the reverse leakage current of MBR30150CT at rated voltage and high temperature?
The reverse leakage current (IR) of MBR30150CT is 5 mA at 150 V reverse voltage and +125°C junction temperature, per the Electrical Specifications table. At 25°C, IR is limited to 100 µA. This low high-temperature leakage minimizes standby power loss in always-on systems such as telecom rectifiers or industrial controllers, directly supporting energy efficiency standards like 80 PLUS Titanium.
