Product details
Overview
MBR7150 from Taiwan Semiconductor is a 7.5A, 150V Schottky barrier rectifier in TO-220AC package, designed for high-efficiency DC/DC conversion and SMPS output stages. It delivers 0.95V forward voltage at 7.5A and 25°C, supports 150A non-repetitive surge current, operates up to 150°C junction temperature, and features guard ring overvoltage protection.
For engineers reviewing the MBR7150 datasheet, MBR7150 pinout, MBR7150 application, or MBR7150 equivalent, key selection criteria include its 150V VRRM, low thermal resistance (RθJC = 5°C/W), AEC-Q101 qualification option (MBR7150H), and suitability for high-current, high-temperature power rectification where low conduction loss is critical.
Technical Context
The MBR7150 uses a single-die Schottky structure optimized for fast switching and minimal reverse recovery charge. Its 150V blocking rating enables use in 48V–110V input DC/DC topologies, while the TO-220AC package provides direct heatsink mounting and 15°C/W junction-to-ambient thermal resistance under standard PCB conditions.
Guard ring integration enhances ruggedness against transient overvoltage events, and the device meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements-critical for automotive and industrial power supplies requiring long-term reliability.

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-75SQ015 | 15V VRRM, 75A IF, TO-263 package; lower VF (0.42V @ 37.5A) but incompatible voltage rating | Not suitable for 150V blocking requirement; only applicable in ≤20V systems | Select only if system VR ≤20V and surface-mount assembly is mandatory |
| ON Semiconductor MBR7150G | Identical electrical specs and TO-220AC package; differs only in lead finish (NiPdAu vs. matte tin) and packaging (tube vs. tape/reel) | Drop-in replacement in footprint and thermal profile; no circuit or layout change required | Preferred for new designs requiring NiPdAu plating or tape-and-reel automation compatibility |
Compared with VS-75SQ015 and MBR7150G, the MBR7150 offers optimal balance of 150V blocking, 7.5A rating, and TO-220AC mountability for medium-power industrial and automotive rectification-where voltage rating and thermal interface simplicity outweigh ultra-low VF or SMT needs.

FAQ
What is the maximum junction temperature rating for the MBR7150?
The MBR7150 has a maximum junction temperature (TJ) rating of +150°C. This allows reliable operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations. Thermal design must ensure that power dissipation-calculated using VF × IF and RθJC-keeps actual TJ below this limit. The MBR7150 datasheet specifies derating curves confirming full 7.5A current capability up to 110°C case temperature.
Is the MBR7150 pin-compatible with other parts in the MBR7xx family?
Yes, all MBR7xx devices-including MBR735, MBR7100, and MBR7150-share identical TO-220AC package dimensions, pinout, and mechanical mounting. Anode (Lead 1), Cathode (Lead 2), and cathode-connected tab are functionally and physically consistent across the family. Voltage rating differences do not affect board layout, enabling easy voltage-scaling upgrades without PCB revision. The MBR7150 maintains the same 0.56 N·m mounting torque specification as other family members.
Does the MBR7150 have AEC-Q101 qualification?
The base MBR7150 is not AEC-Q101 qualified, but the MBR7150H variant is explicitly rated to AEC-Q101. Per TSC's ordering information, the "H" suffix denotes AEC-Q101 qualification, including stress testing for temperature cycling, humidity, and mechanical shock. For automotive applications such as on-board chargers or body control modules, MBR7150H is the appropriate choice; the standard MBR7150 remains suitable for industrial and commercial power supplies where automotive qualification is not mandated.
What is the forward voltage of the MBR7150 at elevated temperature?
At 7.5A and 125°C junction temperature, the MBR7150 exhibits a typical forward voltage (VF) of 0.92V. This represents a slight reduction from its 25°C value of 0.95V-consistent with the negative temperature coefficient of Schottky diodes. This behavior improves thermal stability in parallel configurations and reduces conduction loss drift at high operating temperatures, making the MBR7150 well-suited for thermally demanding applications like sealed power modules.
How does the guard ring feature improve reliability in the MBR7150?
The guard ring in the MBR7150 provides edge termination that suppresses premature avalanche breakdown at the silicon periphery, increasing ruggedness against transient overvoltage events such as load dump or inductive switching spikes. This eliminates the need for external RC snubbers in many SMPS and DC/DC designs, reducing BOM count and board space. The guard ring is integral to the die structure and validated across the full MBR7xx family, contributing directly to the device's ability to sustain 150A surge current without failure.
