Product details
Overview
MBRS1090CTH from Taiwan Semiconductor is a 10A, 90V dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, featuring 0.95V max forward voltage at 10A/25°C, 120A surge capability, and AEC-Q101 qualification for automotive-grade reliability-used as freewheeling diode in DC/DC converters.
For engineers reviewing the MBRS1090CTH datasheet, MBRS1090CTH pinout, MBRS1090CTH application, or MBRS1090CTH equivalent, key selection criteria include reverse voltage rating (90V), thermal resistance (2°C/W), junction temperature range (–55°C to +150°C), moisture sensitivity level (J-STD-020 Level 1), and guard ring–enabled overvoltage protection.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-263AB thermally optimized package, enabling high-current freewheeling or dual-path rectification without paralleling discrete devices. Its 10,000 V/μs dv/dt rating supports fast-switching topologies including synchronous buck and flyback converters.
The device operates across –55°C to +150°C junction temperature, with 2°C/W junction-to-case thermal resistance and 5mA max reverse leakage at 125°C/90V-critical for thermal management in compact automotive power modules and LED driver designs.
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-MBR1090CT-M3/4W | Same 90V VRRM, 10A IF, TO-263AB package; VF = 0.93V max @ 10A/25°C; RθJC = 2.2°C/W. | Slightly higher thermal resistance; identical AEC-Q101 qualification and moisture sensitivity level. | Preferred where Vishay's qualification documentation or traceability chain is required by Tier-1 OEMs. |
| ON Semiconductor MBR1090CT | 90V VRRM, 10A IF, TO-220AC package; VF = 0.95V max @ 10A/25°C; RθJC = 3.0°C/W; no AEC-Q101 stated. | Through-hole mounting only; lacks automotive qualification; higher thermal resistance limits power density. | Acceptable for non-automotive industrial DC/DC where board space and thermal performance are less constrained. |
Compared with VS-MBR1090CT-M3/4W and MBR1090CT, the MBRS1090CTH offers lower thermal resistance (2°C/W vs. 2.2°C/W and 3.0°C/W) and guaranteed AEC-Q101 compliance-making it the preferred choice for space-constrained, thermally demanding automotive power stages requiring zero requalification effort.

FAQ
What is the maximum junction temperature rating for MBRS1090CTH?
The MBRS1090CTH has a maximum junction temperature (TJ MAX) of +150°C and a minimum of –55°C, validated across its full operating range per AEC-Q101 stress testing. This rating enables deployment in under-hood automotive locations where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature within this limit. The device's 2°C/W RθJC facilitates reliable operation when mounted on adequately sized copper thermal pads.
Is MBRS1090CTH pin-compatible with other parts in the MBRS10xxCTH series?
Yes, all MBRS10xxCTH variants-including MBRS1035CTH, MBRS1060CTH, and MBRS10150CTH-share identical TO-263AB (D2PAK) packaging, pinout (Anode A / Common Cathode / Anode B), and mechanical footprint. This allows design reuse across voltage grades without PCB layout changes, though electrical validation for VRRM, VF, and IR remains necessary for each specific application condition.
Does MBRS1090CTH require special handling during reflow soldering?
No special reflow profile is needed for MBRS1090CTH: its J-STD-020 moisture sensitivity level is Level 1, meaning unlimited floor life and compatibility with standard Pb-free reflow profiles (peak 260°C). The matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 molding compound ensures process stability without popcorn cracking or delamination.
What is the reverse leakage current specification for MBRS1090CTH at elevated temperature?
At rated 90V reverse voltage and TJ = 125°C, MBRS1090CTH specifies a maximum reverse leakage current (IR) of 5 mA. At TJ = 25°C and same VR, IR is limited to 100 µA. These values are measured per JEDEC-standard pulse conditions (PW = 30 ms), ensuring realistic characterization for continuous blocking applications such as reverse battery protection circuits.
How does the guard ring feature improve reliability in MBRS1090CTH?
The guard ring in MBRS1090CTH mitigates edge-related avalanche breakdown by controlling electric field distribution at the silicon periphery. This structural enhancement increases robustness against voltage transients and localized heating-particularly critical in automotive 12V/24V systems exposed to load dump events. It directly contributes to the device's AEC-Q101 qualification and long-term stability in high-voltage blocking roles.
