Product details
Overview
MBRF8150CT from Taiwan Semiconductor is an 8A, 150V dual-die Schottky barrier rectifier in ITO-220AB package, featuring 0.95V forward voltage at 4A/25°C, 150A surge current capability, and AEC-Q101 qualification option (H-suffix variant). It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters.
For engineers reviewing the MBRF8150CT datasheet, MBRF8150CT pinout, MBRF8150CT application, or MBRF8150CT equivalent, key selection factors include its 150V VRRM, dual-common-cathode configuration, 6°C/W junction-to-case thermal resistance, and 5mA reverse leakage at 125°C - critical for thermally constrained, high-reliability power stages.
Technical Context
The MBRF8150CT integrates two independent Schottky diodes in a single ITO-220AB thermally optimized package with common cathode connection. Its 150V repetitive peak reverse voltage and 10,000 V/µs dv/dt rating support fast-switching topologies in 48V automotive systems and industrial SMPS.
Designed for surface-mount-compatible through-hole assembly, it delivers low conduction loss (0.95V @ 4A) and high surge robustness (150A, 8.3ms half-sine), with guard ring protection enabling stable operation under transient overvoltage conditions.
Key Specifications

| VF @ 4A, 25°C | 0.95 V - low conduction loss enabling >92% efficiency in 12V–48V output stages |
| RθJC | 6 °C/W - enables direct heatsink mounting for thermal management without additional interface layers |
| IR @ 150V, 125°C | 5 mA - reverse leakage level defining minimum hold-off stability in high-temp environments |

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-MBRB8150CT | Same ITO-220AB package, 0.92V VF @ 4A, 125°C IR = 4.5mA, no AEC-Q101 option | Preferred where lowest forward drop is prioritized over automotive qualification | Select when optimizing for efficiency in non-automotive industrial systems |
| ON Semiconductor MBR8150CT | Identical electrical specs and package; differs in marking, traceability, and RoHS compliance documentation | Drop-in replacement in legacy designs with ON Semi sourcing requirements | Choose for BOM continuity in existing ON Semi-based platforms |
Compared with MBRF8150CT, VS-MBRB8150CT offers marginally lower VF but lacks AEC-Q101 validation, while MBR8150CT provides identical performance with alternate supply-chain assurance - making MBRF8150CT optimal for new automotive designs requiring qualified components.

FAQ
What is the maximum junction temperature rating for the MBRF8150CT?
The MBRF8150CT has a maximum junction temperature (TJ) of +150°C, verified per JESD22-A103 and supported by its 6°C/W junction-to-case thermal resistance. This rating allows sustained operation in engine-bay-mounted DC-DC modules when properly heatsinked. The MBRF8150CT must be derated linearly above 75°C case temperature per the forward current derating curve in the datasheet.
Does the MBRF8150CT have AEC-Q101 qualification?
The base MBRF8150CT is not AEC-Q101 qualified; however, the MBRF8150CTH variant - identical in all electrical and mechanical specifications - is fully AEC-Q101 qualified per Rev. J2105. The "H" suffix denotes qualification, and MBRF8150CTH is the recommended part for automotive powertrain and ADAS applications requiring stress-tested reliability.
What is the pin configuration and polarity marking for the MBRF8150CT?
The MBRF8150CT uses a three-terminal ITO-220AB package with Pin 1 = Anode A, Pin 2 = Common Cathode (tab-connected), Pin 3 = Anode B. Polarity is marked on the device body with a cathode band adjacent to Pin 2, and the tab is electrically connected to the cathode - confirmed in the official TSC package outline drawing and marking diagram.
How does the forward voltage of the MBRF8150CT compare across temperature and current?
The MBRF8150CT exhibits a typical VF of 0.95V at 4A and 25°C, rising to ~1.05V at 125°C. At 8A, VF reaches ~1.15V (25°C) per the forward characteristics curve. These values are measured under pulsed conditions (0.3ms PW) and reflect actual conduction loss behavior used in thermal modeling for the MBRF8150CT.
Is the MBRF8150CT halogen-free and RoHS compliant?
Yes, the MBRF8150CT is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the TSC datasheet (Rev. J2105). The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm - verified via material declarations and third-party testing reports.
