Product details

Overview

MBRAD15150H from Taiwan Semiconductor is a 15 A, 150 V Schottky barrier rectifier in ThinDPAK package, designed for low-loss DC/DC conversion and reverse battery protection in automotive electronics. It features 0.86 V forward voltage at 15 A/25°C, 240 A surge rating, AEC-Q101 qualification, and junction temperature up to +150°C.

For engineers reviewing the MBRAD15150H datasheet, MBRAD15150H pinout, MBRAD15150H application, or MBRAD15150H equivalent, key selection factors include its AEC-Q101 compliance, thermal resistance (R_θJL = 2.2°C/W), moisture sensitivity level 1, RoHS/halogen-free status, and suitability for high-frequency freewheeling in 12 V/24 V automotive systems.

Technical Context

The MBRAD15150H is a single-die Schottky rectifier optimized for low forward voltage and fast switching in automotive power rails. Its 150 V V_RRM, 15 A continuous current, and 240 A I_FSM (8.3 ms) support robust operation under load dump and cold-crank conditions.

Thermal design is enabled by R_θJL = 2.2°C/W with ideal heatsink and R_θJC = 2.6°C/W to case, while its ThinDPAK footprint (JEDEC TO-252-AE) ensures compatibility with automated SMT placement and meets JESD201 Class 2 whisker resistance.

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-15EWH15-M3	Same 15 A/150 V rating; VF = 0.87 V @ 15 A, 25°C; R_θJA = 15°C/W (higher than MBRAD15150H's 12°C/W).	Also AEC-Q101 qualified but uses PowerPAK SO-8 package-different footprint and thermal interface.	Select when SO-8 layout is fixed; verify thermal performance with reduced copper area.
ON Semiconductor SB15E150	15 A/150 V; VF = 0.89 V @ 15 A, 25°C; TJ max = +175°C; R_θJL not published-only R_θJA = 14°C/W given.	Qualified to AEC-Q101 but lacks published R_θJL; no moisture sensitivity level stated.	Prefer for higher ambient temperature designs (>125°C); confirm MSL and thermal path with layout simulation.

Compared with VS-15EWH15-M3 and SB15E150, the MBRAD15150H offers superior thermal coupling (R_θJL = 2.2°C/W), documented MSL 1 handling, and lower typical V_F, making it optimal for space- and thermally constrained automotive modules where PCB copper is the primary heatsink.

FAQ

What is the maximum junction temperature rating for the MBRAD15150H?

The MBRAD15150H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature within this limit using the specified R_θJL = 2.2°C/W path to PCB copper.

Is the MBRAD15150H qualified for automotive use?

Yes, the MBRAD15150H is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and highly accelerated stress testing required for discrete semiconductors in automotive applications. The qualification applies to the exact MBRAD15150H device marked "15150" per ordering code and version A2303.

What does the marking code "15150" on the MBRAD15150H indicate?

The marking code "15150" laser-etched on the top surface of the MBRAD15150H identifies the device as a 15 A, 150 V Schottky rectifier. It is part of the standardized TSC marking scheme and appears alongside date code (YWW) and factory code (F), confirming authenticity and revision level (A2303) per datasheet page 1.

Does the MBRAD15150H require baking before reflow soldering?

No, the MBRAD15150H has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without dry-pack or baking. Standard reflow profiles-including peak temperatures up to 260°C-can be applied directly without preconditioning, simplifying SMT line integration.

What is the thermal resistance from junction to lead (R_θJL) for the MBRAD15150H?

The MBRAD15150H has a typical junction-to-lead thermal resistance (R_θJL) of 2.2°C/W, measured with ideal heatsink conditions. This value reflects conduction through the cathode pad into PCB copper and is critical for calculating junction temperature rise in layouts where the exposed tab is soldered to ≥100 mm² of 2 oz copper.
