Product details
Overview
MBRAD20100H from Taiwan Semiconductor is a 20 A, 100 V Schottky barrier rectifier in ThinDPAK package, designed for high-efficiency DC/DC conversion and freewheeling in automotive power systems. It features low forward voltage (0.80 V at 20 A, 25°C), high surge capability (330 A @ 8.3 ms), AEC-Q101 qualification, and junction temperature rating up to +150°C.
For engineers reviewing the MBRAD20100H datasheet, MBRAD20100H pinout, MBRAD20100H application, or MBRAD20100H equivalent, key selection criteria include forward voltage drop at operating current, thermal resistance (RθJL = 2.0°C/W), surge robustness, AEC-Q101 compliance, and ThinDPAK mounting compatibility with automated SMT lines.
Technical Context
The MBRAD20100H is a single-die Schottky rectifier optimized for low-loss unidirectional conduction in high-frequency switching topologies. Its 0.71 V typical forward voltage at 10 A/25°C and 494 pF junction capacitance support fast recovery and minimal switching loss in 100 kHz–1 MHz DC/DC converters.
Thermal design leverages its low RθJL of 2.0°C/W (with ideal heatsink) and RθJC of 2.5°C/W, enabling sustained 20 A average current under controlled board-level cooling. The device's -55°C to +150°C operating range and moisture sensitivity level 1 rating ensure reliability in automotive under-hood environments.
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 |
|---|---|---|---|
| Vishay VS-20BQ100-M3/45 | Same 20 A / 100 V rating; VF = 0.79 V max @ 20 A, 25°C; RθJA = 12.5°C/W; TO-263 package | TO-263 has larger footprint and higher RθJA; less suitable for space-constrained automotive modules | Choose if existing layout uses TO-263 and thermal margin allows 1.0°C/W higher RθJA |

FAQ
What is the maximum junction temperature rating for the MBRAD20100H?
The MBRAD20100H has a maximum junction temperature (TJMAX) of +150°C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C. Derating curves confirm sustained 20 A current capability up to 125°C case temperature when mounted on appropriate copper area. The MBRAD20100H must not be operated beyond this limit to avoid permanent degradation.
Is the MBRAD20100H suitable for reverse battery protection in 24 V systems?
Yes, the MBRAD20100H is well-suited for reverse battery protection in 24 V systems due to its 100 V VRRM, 330 A IFSM (8.3 ms), and low 0.85 V max forward voltage at 20 A. Its AEC-Q101 qualification and -55°C to +150°C operating range ensure robustness against jump-start surges and cold-cranking conditions. The MBRAD20100H's ThinDPAK package also supports high-current PCB traces required for main power rails.
Does the MBRAD20100H have a defined pinout for PCB layout?
Yes, the MBRAD20100H uses a 3-pin ThinDPAK (TO-252 AE) package with standardized pinout: Pin 1 = Anode, Pin 2 = Cathode, and Pin 3 = Exposed thermal pad (electrically connected to cathode). The cathode band marks the cathode side. The thermal pad must be soldered to a minimum 100 mm² copper pour for optimal RθJA = 11.5°C/W. Layout guidelines are provided in TSC document HQ2SD07-TDPAK-065 REV A.
What is the moisture sensitivity level (MSL) of the MBRAD20100H?
MBRAD20100H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or baking prior to reflow soldering. This simplifies SMT handling and eliminates moisture-related popcorning risk. The device's matte tin-plated leads and UL 94V-0 molding compound further enhance process robustness. MBRAD20100H reels are shipped in standard tape-and-reel format (4,500 units per reel).
How does the forward voltage of the MBRAD20100H vary with temperature?
The MBRAD20100H exhibits negative temperature coefficient behavior: VF decreases as junction temperature rises - e.g., 0.80 V max at 20 A/25°C drops to 0.71 V max at 20 A/125°C. This improves efficiency at elevated temperatures but requires thermal design to maintain safe TJ. The MBRAD20100H's 0.58 V typ at 10 A/125°C reflects its stable Schottky conduction mechanism across automotive operating ranges.
