Product details
Overview
MBRAD5150H from Taiwan Semiconductor is a 5 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. It features 0.83 V forward voltage at 5 A/25°C, 120 A surge capability, and AEC-Q101 qualification.
For engineers reviewing the MBRAD5150H datasheet, MBRAD5150H pinout, MBRAD5150H application, or MBRAD5150H equivalent, key selection criteria include junction-to-lead thermal resistance (2.3°C/W), moisture sensitivity level 1 compliance, and TJ max of 150°C under high-reliability automotive operating conditions.
Technical Context
This Schottky rectifier uses a single-die construction optimized for high-frequency switching in automotive power conversion. Its low VF (0.67 V typ. @ 5 A/125°C) and fast recovery enable efficient operation in DC/DC converters and inverters where conduction loss dominates.
The ThinDPAK package provides enhanced thermal performance via direct lead-frame heat transfer-RθJL = 2.3°C/W with ideal heatsink-and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

FAQ
What is the marking code for MBRAD5150H?
The MBRAD5150H is marked "5150" on the device body per its ordering information. This 4-digit code identifies the voltage (150 V) and current (5 A) ratings and distinguishes it from other variants in the ThinDPAK Schottky family. The full part number MBRAD5150H appears on packaging reels and documentation but not on the die surface.
Is MBRAD5150H suitable for reverse battery protection in 48 V automotive systems?
Yes, the MBRAD5150H is rated for 150 V VRRM and qualified to AEC-Q101, making it suitable for reverse battery protection in both 12 V and 48 V automotive architectures. Its 120 A IFSM withstands load dump transients, and its 0.83 V VF at 5 A minimizes voltage drop and power loss during normal operation in the main power rail.
What is the thermal performance of MBRAD5150H when mounted on a standard PCB?
When mounted on a 2" × 3" × 0.25" aluminum plate, the MBRAD5150H achieves RθJA = 13.6°C/W and RθJC = 3.8°C/W. With an ideal heatsink, RθJL drops to 2.3°C/W-enabling >4 W power dissipation at ΔT = 10°C above ambient. PCB layout must maximize copper area under Pin 2 (cathode/thermal pad) for optimal performance.
Does MBRAD5150H require baking before reflow soldering?
No, the MBRAD5150H has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without preconditioning or baking. This simplifies SMT line integration and eliminates risk of popcorning during assembly.
How does the forward voltage of MBRAD5150H change with temperature?
The MBRAD5150H exhibits negative temperature coefficient behavior: VF decreases as junction temperature rises-0.83 V at 5 A/25°C vs. 0.67 V at 5 A/125°C. This improves conduction efficiency under thermal stress, reducing self-heating runaway risk in high-ambient environments like engine compartments.
