Taiwan Semiconductor Corporation MBRAD10100H

Overview

MBRAD10100H from Taiwan Semiconductor is a 10A, 100V Schottky barrier rectifier in ThinDPAK package, designed for high-efficiency DC/DC conversion and reverse battery protection in automotive electronics. It features low forward voltage (0.79 V at 10 A, 25°C), 200 A surge capability, AEC-Q101 qualification, and junction temperature rating up to +150°C.

For engineers reviewing the MBRAD10100H datasheet, MBRAD10100H pinout, MBRAD10100H application, or MBRAD10100H equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 2.5 °C/W junction-to-lead thermal resistance with ideal heatsink, RoHS/halogen-free compliance, and suitability for automated SMT placement in space-constrained automotive modules.

Technical Context

This Schottky rectifier uses a single-die construction optimized for low conduction loss in high-frequency switching topologies. Its 0.79 V max forward voltage at 10 A and 25°C directly enables higher power conversion efficiency versus standard PN diodes, while the 260 pF junction capacitance at 4 V supports fast switching in DC/DC converters up to several hundred kHz.

The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity-critical for reflow compatibility and long-term reliability in under-hood automotive environments.

FAQ

What is the maximum junction temperature rating for the MBRAD10100H?

The MBRAD10100H has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings table. This allows continuous operation in under-hood environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit. The MBRAD10100H achieves this with R_θJL = 2.5 °C/W when mounted on an ideal heatsink.

Is the MBRAD10100H suitable for reverse battery protection in 24 V automotive systems?

Yes, the MBRAD10100H is rated for 100 V repetitive peak reverse voltage (V_RRM) and 200 A surge current (I_FSM), making it suitable for reverse polarity protection in 24 V systems. Its low forward voltage ensures minimal voltage drop during normal operation, and the AEC-Q101 qualification confirms robustness against automotive transients. The MBRAD10100H is widely deployed in this role across Tier 1 lighting and body control modules.

Does the MBRAD10100H have a halogen-free and RoHS-compliant construction?

Yes, the MBRAD10100H is explicitly stated as halogen-free and RoHS compliant in its official datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These material attributes satisfy EU ELV Directive and major automotive OEM environmental requirements. The MBRAD10100H carries full compliance documentation for traceable sourcing.

What is the marking code printed on the MBRAD10100H package?

The marking code on the MBRAD10100H device surface is "10100", as specified in the Absolute Maximum Ratings table. This 5-digit code identifies the device as a 10 A, 100 V Schottky rectifier and is laser-marked on the top surface adjacent to the cathode band. The full part number MBRAD10100H appears only on tape-and-reel packaging and shipping labels-not on the die itself.

How does the MBRAD10100H compare thermally to standard TO-252 Schottky rectifiers?

The MBRAD10100H uses a ThinDPAK variant of TO-252 with optimized internal thermal path, achieving R_θJL = 2.5 °C/W (with ideal heatsink) versus typical 3.0–3.5 °C/W for standard TO-252 devices. Its exposed drain tab is electrically tied to the cathode and must be soldered to ≥100 mm² copper area. This design reduces thermal resistance by up to 25%, allowing higher current handling in constrained layouts. The MBRAD10100H's thermal performance is validated per JEDEC JESD51-14 standards.
