Product details
Overview
MBRS1090H from Taiwan Semiconductor is a 10A, 90V Schottky barrier rectifier in TO-263AB (D2PAK) package, optimized for low forward voltage drop (0.85 V at 10 A, 25°C), high surge current capability (120 A), and automotive-grade reliability (AEC-Q101 qualified). It serves as a freewheeling or reverse-battery protection diode in DC/DC converters and car lighting systems.
For engineers reviewing the MBRS1090H datasheet, MBRS1090H pinout, MBRS1090H application, or MBRS1090H equivalent, key selection criteria include its 90 V repetitive peak reverse voltage, 175°C maximum junction temperature, 2°C/W junction-to-case thermal resistance, and compatibility with automated SMT placement.
Technical Context
The MBRS1090H employs a single-die Schottky structure with guard ring overvoltage protection, enabling fast switching and low conduction loss. Its 120 A non-repetitive surge rating supports transient load conditions in automotive power rails.
Rated for operation from –55°C to +175°C and moisture sensitivity level 1 (J-STD-020), it meets stringent automotive environmental requirements. The device's 10,000 V/μs critical dv/dt rating ensures stable blocking under rapid voltage transients.

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-MBR1090CT | TO-220AC package, dual common-cathode configuration; VF ≈ 0.82 V @ 10 A, 25°C | Requires through-hole mounting and different thermal interface; not AEC-Q101 qualified | Preferred for legacy through-hole designs where footprint change is prohibitive |
| ON Semiconductor MBR1090CT | TO-220AB package, single die, VF ≈ 0.84 V @ 10 A, 25°C; no AEC-Q101 certification | Lacks automotive qualification; lower surge rating (100 A IFSM) | Suitable for industrial DC/DC where AEC-Q101 is not mandated |
Compared with VS-MBR1090CT and MBR1090CT, the MBRS1090H offers surface-mount compatibility, AEC-Q101 qualification, and superior thermal resistance (2°C/W vs. ~3.5°C/W for TO-220), making it optimal for space-constrained, high-reliability automotive modules.

FAQ
What is the maximum junction temperature rating for MBRS1090H?
The MBRS1090H has a maximum junction temperature (TJ max) of 175°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments where ambient temperatures exceed 125°C. Derating curves in the datasheet confirm sustained 10 A forward current capability up to 110°C case temperature. Thermal design must maintain RθJC ≤ 2°C/W via adequate PCB copper area.
Is MBRS1090H suitable for reverse battery protection in 24 V commercial vehicles?
Yes, MBRS1090H is suitable for reverse battery protection in 24 V systems. Its 90 V VRRM exceeds the 35 V ISO 7637-2 load dump specification for 24 V vehicles, and its 120 A IFSM handles cranking surges. The device's AEC-Q101 qualification and –55°C to +175°C operating range further validate its use in heavy-duty truck and bus electronics where thermal and electrical stress is elevated.
Does MBRS1090H have a halogen-free and RoHS-compliant construction?
Yes, MBRS1090H is both halogen-free per IEC 61249-2-21 and RoHS compliant. The molding compound and plating meet automotive material declaration requirements, and the matte tin-plated leads comply with J-STD-002 solderability standards. These attributes are documented in Taiwan Semiconductor's official product change notices and material declarations for the MBRS10xH series.
What is the forward voltage drop of MBRS1090H at 10 A and 125°C?
The MBRS1090H exhibits a typical forward voltage (VF) of 0.71 V at 10 A and TJ = 125°C, per the Electrical Specifications table in the Taiwan Semiconductor datasheet (Version A2103, Page 3). This low, temperature-stable VF ensures consistent conduction loss across automotive operating ranges and contributes to high overall converter efficiency in thermally demanding applications.
Can MBRS1090H be used in place of MBRS1060H in an existing design?
Yes, MBRS1090H can replace MBRS1060H in most designs due to identical package (TO-263AB), pinout, and thermal characteristics. The only functional difference is higher VRRM (90 V vs. 60 V), offering increased margin against voltage transients. No PCB or layout changes are required, but verify that the higher blocking voltage does not affect snubber or clamping network design in sensitive topologies.
