Product details
Overview
MBRF5150 from Taiwan Semiconductor is a 5A, 150V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (1.02 V at 5A, 25°C), 120A surge capability, 3°C/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency output rectifier in DC-DC converters and SMPS.
For engineers reviewing the MBRF5150 datasheet, MBRF5150 pinout, MBRF5150 application, or MBRF5150 equivalent, key selection criteria include its 150V reverse voltage rating, single-die configuration, matte tin-plated leads compliant with J-STD-002, UL recognition (E-326243), and halogen-free molding compound per IEC 61249-2-21.
Technical Context
The MBRF5150 operates as a unidirectional power rectifier with a single silicon die optimized for fast switching and minimal conduction loss. Its 150V VRRM, 5A average forward current, and 120A non-repetitive surge rating support high-density power conversion topologies requiring robust transient handling.
Thermally, it delivers 3°C/W junction-to-case resistance and operates across –55°C to +150°C junction temperature range. The device uses guard ring structure for over-voltage protection and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
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 |
|---|---|---|---|
| STPS5L150 | Same 5A/150V rating; TO-220AC package; VF = 0.92 V (typ) at 5A, 25°C - 100 mV lower than MBRF5150 | No AEC-Q101 qualification; UL recognition not specified | Preferred where lowest conduction loss is critical and automotive qualification is not required |
| SB5150 | 5A/150V Schottky; DO-201AD package; VF = 0.95 V (max) at 5A, 25°C; IFSM = 100 A - 20 A lower surge rating | Lower thermal performance (RθJC ≈ 15°C/W); unsuitable for high-power density designs | Acceptable for cost-sensitive, low-power adapters where heatsinking is impractical |
Compared with STPS5L150 and SB5150, the MBRF5150 uniquely combines AEC-Q101 qualification, UL recognition, and 3°C/W thermal resistance in ITO-220AC - making it the only option among the three validated for automotive under-hood use with direct bolt-down heatsinking.

FAQ
What is the maximum junction temperature rating for the MBRF5150?
The MBRF5150 has a maximum junction temperature (TJ) of +150°C, enabling reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. This rating is validated per the device's absolute maximum ratings table and supported by its 3°C/W junction-to-case thermal resistance. Thermal design must ensure the MBRF5150 stays within this limit under worst-case load and ambient conditions.
Is the MBRF5150 pin-compatible with other devices in the MBRF5xxx series?
Yes - all MBRF5100, MBRF5150, and MBRF5200 devices share identical ITO-220AC package dimensions, pinout (anode, cathode, isolated tab), and mounting specifications. The only functional difference is the rated VRRM: 100V, 150V, and 200V respectively. Designers may substitute MBRF5150 for MBRF5100 or MBRF5200 without PCB changes, provided voltage derating and application requirements align.
Does the MBRF5150 meet automotive qualification standards?
Yes - the MBRF5150 is AEC-Q101 qualified, confirming its suitability for automotive power electronics including body control modules, infotainment systems, and ADAS power supplies. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life. The "H" suffix in ordering codes (e.g., MBRF5150H) explicitly denotes AEC-Q101 compliance.
What is the forward voltage specification of the MBRF5150 at elevated temperature?
At 5A and 125°C junction temperature, the MBRF5150 exhibits a maximum forward voltage (VF) of 0.92 V. This value is 100 mV higher than its 25°C rating (1.02 V max), reflecting typical Schottky behavior where VF decreases slightly with rising temperature. This parameter is critical for thermal runaway analysis and efficiency modeling across operating temperature ranges.
How is the MBRF5150 marked on the device body?
The MBRF5150 is marked with its full part number "MBRF5150" on the top surface of the ITO-220AC package, along with green compound indicator (G), date code (YWW), and factory code (F). Polarity is indicated by a cathode band adjacent to the cathode lead. These markings comply with JEDEC standards and enable visual verification of part identity and orientation during assembly and inspection.
