Product details
Overview
MBRS1050H from Taiwan Semiconductor is a 10A, 50V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage (0.80 V at 10A, 25°C) and high surge capability (120 A IFSM), used in DC/DC converters and reverse battery protection circuits.
For engineers reviewing the MBRS1050H datasheet, MBRS1050H pinout, MBRS1050H application, or MBRS1050H equivalent, key selection criteria include repetitive peak reverse voltage (50 V), junction-to-case thermal resistance (2 °C/W), AEC-Q101 qualification, and moisture sensitivity level 1 compliance.
Technical Context
The MBRS1050H employs a single-die Schottky structure with guard ring overvoltage protection, enabling fast switching and low conduction loss. Its 50 V VRRM rating targets mid-voltage automotive and industrial power rails where efficiency and thermal management are critical.
Designed for surface-mount automated placement, it supports continuous 10 A forward current at up to 175 °C junction temperature and withstands 8.3 ms half-sine surge currents up to 120 A without degradation.

FAQ
What is the maximum junction temperature rating for MBRS1050H?
The MBRS1050H has a maximum junction temperature (TJ) of +175 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. This rating is supported by its TO-263AB package and 2 °C/W junction-to-case thermal resistance. Derating curves confirm sustained 10 A operation up to 125 °C case temperature. The MBRS1050H must be mounted on adequate copper area to maintain this limit in practice.
Is MBRS1050H qualified for automotive applications?
Yes, the MBRS1050H is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity bias for discrete semiconductors. This qualification validates its suitability for automotive power systems such as body control modules and lighting drivers. The MBRS1050H's marking code "MBRS1050" and version "A2103" are traceable to certified lots.
What is the forward voltage drop of MBRS1050H at 10 A and 125 °C?
The MBRS1050H exhibits a maximum forward voltage (VF) of 0.70 V at 10 A and 125 °C junction temperature, per the manufacturer's electrical specifications. This value reflects real-world thermal conditions in enclosed modules and confirms stable conduction loss across temperature. At room temperature (25 °C), VF is 0.80 V max-both values are measured under pulsed conditions to avoid self-heating artifacts. The MBRS1050H maintains this performance across its full rated current range.
Does MBRS1050H have a guard ring structure?
Yes, the MBRS1050H incorporates a guard ring design explicitly stated in its features list to enhance overvoltage protection and improve edge termination robustness. This structure increases resistance to avalanche breakdown and improves dv/dt immunity-rated at 10,000 V/μs. The guard ring contributes directly to the device's ability to withstand transient surges in automotive 12 V systems without failure. This feature is integral to the MBRS1050H's AEC-Q101 qualification.
What is the moisture sensitivity level (MSL) of MBRS1050H?
The MBRS1050H has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it has no floor life limitation and may be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and eliminates yield loss from moisture-related popcorning. The MBRS1050H's epoxy molding compound and lead finish are fully compatible with standard lead-free reflow profiles. This MSL rating applies to all units shipped in tape-and-reel packaging (800/reel).
