Product details
Overview
MBRAD8150H from Taiwan Semiconductor is an AEC-Q101-qualified 8 A, 150 V Schottky barrier rectifier in ThinDPAK package, designed for low-loss freewheeling and reverse battery protection in automotive DC/DC converters and car lighting systems.
For engineers reviewing the MBRAD8150H datasheet, MBRAD8150H pinout, MBRAD8150H application, or MBRAD8150H equivalent, key selection factors include its 0.84 V forward voltage at 8 A/25°C, 150 A surge rating, -55°C to +150°C junction temperature range, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance.
Technical Context
The MBRAD8150H employs a single-die Schottky structure optimized for high-frequency switching with low conduction loss. Its 155 pF junction capacitance at 1 MHz/4 V and 0.71 V typical VF at 8 A/125°C support stable operation in fast-switching DC/DC topologies.
Thermal performance is defined by RθJL = 2.4°C/W (with ideal heatsink) and RθJA = 12.6°C/W on 2" × 3" × 0.25" aluminum plate, enabling reliable 8 A continuous conduction under automotive ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 8 A continuous - supports high-current output rails in compact automotive power stages |
| Peak Reverse Voltage (VRRM) | 150 V - withstands load-dump transients in 12 V/24 V vehicle systems |
| Surge Current (IFSM) | 150 A (8.3 ms) - handles inrush and fault currents without failure |
| Forward Voltage (VF) | 0.84 V max at 8 A/25°C - reduces conduction loss and thermal stress vs. silicon diodes |
| Junction Temp Range (TJ) | -55°C to +150°C - meets under-hood automotive thermal requirements |
| Junction Capacitance (CJ) | 155 pF at 1 MHz/4 V - minimizes switching noise and EMI in high-frequency converters |
| Thermal Resistance (RθJA) | 12.6°C/W on standard Al plate - enables passive thermal management in space-constrained modules |
Pinout & Package

Applications
| Automotive DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Step-down conversion in 12 V/48 V hybrid architectures with >200 kHz switching frequency. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous or asynchronous buck regulators. Use Value: 0.84 V VF at 8 A reduces power loss by ~35% versus comparable silicon rectifiers, lowering thermal design burden. | Use Scenario: Input protection circuitry for infotainment head units and ADAS ECUs exposed to accidental reverse polarity connection. IC Role / Device Role / Timing Role: Series-blocking diode placed between battery feed and system input. Use Value: 150 V VRRM withstands jump-start transients; low VF avoids unnecessary voltage drop during normal operation. |

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-MBRB8150TRPBF | Same 8 A/150 V rating, TO-263 (D2PAK) package, RθJA = 13°C/W | Larger footprint; requires different PCB land pattern and thermal pad layout | Select if existing design uses D2PAK or needs marginally higher surge rating (200 A @ 8.3 ms) |
| ON Semiconductor MBR8150CT | 8 A/150 V dual common-cathode configuration in TO-220AC; VF = 0.89 V max @ 8 A | Through-hole mounting; higher VF increases conduction loss; not AEC-Q101 qualified | Select only for non-automotive industrial prototypes where cost outweighs qualification and efficiency |
Compared with VS-MBRB8150TRPBF and MBR8150CT, the MBRAD8150H offers AEC-Q101 qualification, moisture level 1 handling, and optimized thermal resistance in ThinDPAK - making it the preferred choice for production automotive power modules requiring zero rework risk and validated reliability.

FAQ
What is the marking code printed on the MBRAD8150H device?
The MBRAD8150H carries the marking code "8150" on its top surface, consistent with Taiwan Semiconductor's standardized ThinDPAK labeling convention and verified in the official datasheet revision A2303. This code identifies the device as the 150 V variant within the MBRAD8xxH series and is used for traceability and visual inspection during assembly.
Is the MBRAD8150H suitable for reflow soldering in automated SMT lines?
Yes, the MBRAD8150H is fully compatible with standard lead-free reflow profiles. Its moisture sensitivity level 1 rating per J-STD-020 means no baking is required prior to assembly, and its matte tin-plated leads meet J-STD-002 solderability requirements - ensuring robust wetting and joint formation in high-volume automotive manufacturing.
Does the MBRAD8150H have a built-in thermal pad, and how should it be connected?
Yes, the MBRAD8150H features an exposed copper thermal pad (Pin 3) electrically tied to the cathode. It must be soldered to a minimum 100 mm² PCB copper pour with ≥4 thermal vias (0.3 mm diameter) to achieve the specified RθJA = 12.6°C/W. Failure to connect this pad degrades thermal performance and risks premature junction overheating under 8 A load.
What is the maximum reverse leakage current of the MBRAD8150H at elevated temperature?
At 125°C and rated 150 V reverse voltage, the MBRAD8150H exhibits a maximum reverse leakage current of 2 mA, as specified in the Electrical Specifications table. This value is critical for low-power standby modes in automotive modules, where excessive IR could drain battery charge over extended parking periods.
Can the MBRAD8150H replace a standard PN-junction rectifier in an existing 12 V automotive design?
Yes, the MBRAD8150H can directly replace PN rectifiers such as 1N5408 or BYV26E in most 12 V automotive applications, provided layout accommodates ThinDPAK footprint and thermal pad. Its lower VF reduces heat generation, but designers must verify that 150 V VRRM meets system transient requirements - especially in load-dump scenarios exceeding 100 V.
