Product details
Overview
MBRS1090HMNG from Taiwan Semiconductor is a 10A, 90V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion and SMPS secondary-side rectification with low forward voltage (0.85 V at 10 A, 25°C) and high surge capability (120 A IFSM). It features guard ring overvoltage protection, moisture sensitivity level 1, and RoHS/halogen-free compliance.
For engineers reviewing the MBRS1090HMNG datasheet, MBRS1090HMNG pinout, MBRS1090HMNG application, or MBRS1090HMNG equivalent, key selection factors include its 90 V VRRM rating, 2°C/W junction-to-case thermal resistance, 175°C maximum junction temperature, and suitability for high-current, thermally constrained switching power supplies.
Technical Context
This Schottky rectifier uses a single-die construction with platinum-silicide or similar low-barrier metallization to achieve fast recovery (no reverse recovery charge), minimal conduction loss, and operation up to 175°C junction temperature. Its TO-263AB package provides low thermal resistance (RθJC = 2°C/W) and robust mechanical mounting for high-power density layouts.
The device is rated for repetitive peak reverse voltage of 90 V and exhibits 5 mA maximum reverse leakage current at 125°C - critical for maintaining efficiency in high-temperature DC/DC stages. Its 10,000 V/μs dv/dt rating ensures stability under fast-switching conditions typical in synchronous rectifier circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum blocking voltage before breakdown; defines usable input/output voltage range in isolated/non-isolated converters |
| IF | 10 A continuous - Sustained output current capability at TA ≤ 75°C with adequate heatsinking |
| IFSM | 120 A (8.3 ms half-sine) - Withstands inrush and transient surges without failure during startup or fault events |
| VF @ 10A, 25°C | 0.85 V - Directly reduces conduction loss and improves system efficiency vs. silicon diodes (~0.4–0.5 V lower drop) |
| RθJC | 2 °C/W - Enables direct thermal coupling to PCB copper or heatsink; supports >8 W dissipation with <20°C rise above case |
| TJ max | 175 °C - Allows operation in high-ambient industrial or enclosed power supply environments without derating |
| IR @ 125°C | 5 mA - Low leakage preserves efficiency at elevated temperatures; avoids thermal runaway in parallel configurations |
Pinout & Package
Package: TO-263AB (D2PAK) - Surface-mount, 3-terminal power package with exposed anode tab for enhanced thermal and electrical performance. Matte tin-plated leads, J-STD-002 solderable, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Current entry point; electrically and thermally connected to metal tab | Must be soldered to large copper pour or heatsink for thermal management and low-inductance return path |
| Cathode (Pin 2) | Current exit point; marked side of device | Connected to output rail or ground reference; polarity must match PCB silkscreen and schematic symbol |
| NC / Thermal Pad (Pin 1) | No internal connection; structural support only | Not electrically active; may be left floating or grounded per layout requirements - no functional role in rectification |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Improves ruggedness against transient overvoltage (e.g., inductive kickback) without requiring external snubbers |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without special handling |
| High IFSM (120 A) | Supports reliable operation in applications with high peak currents such as LLC resonant converters or PFC boost stages |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS directives; suitable for export-controlled and environmentally regulated end equipment |
| Low RθJC (2°C/W) | Enables compact thermal design: 10 A conduction at 175°C TJ requires only ~20°C temperature rise across case interface |
Applications
| Server VRM Output Rectification | Laptop AC Adapter Secondary Side |
|---|---|
Use Scenario: High-current, low-voltage DC output stage in multiphase buck converters delivering 12 V → 1.2 V at >100 A. IC Role / Device Role / Timing Role: Primary unidirectional power switch replacing MOSFET synchronous rectifiers where gate drive complexity is undesirable.

IC Role / Device Role / Timing Role: Unidirectional current valve preventing backfeed between supplies; conducts up to 10 A per module. Use Value: Low VF minimizes insertion loss (<0.85 V × 10 A = 8.5 W per diode), reducing heat buildup and enabling higher power density in confined shelf space. |
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-M3/45 | TO-220AC package; dual common-cathode die; VF ≈ 0.82 V @ 10 A, 25°C; RθJC = 3.5°C/W | Requires through-hole mounting and separate cathode routing; less thermally efficient than D2PAK | Prefer when dual-diode topology or legacy through-hole assembly is required |
| ON Semiconductor MBR1090CT | TO-220AB package; single-die configuration; VF ≈ 0.87 V @ 10 A, 25°C; RθJC = 4.0°C/W | Higher thermal resistance limits power density; not moisture-sensitive-level-1 qualified | Acceptable for cost-sensitive, non-high-reliability designs with ample heatsinking |
Compared with VS-MBR1090CT-M3/45 and MBR1090CT, the MBRS1090HMNG offers superior thermal performance (2°C/W vs. ≥3.5°C/W), surface-mount compatibility, and moisture-insensitive handling - making it preferred for high-density, automated, and thermally demanding power supply designs.

FAQ
What is the maximum junction temperature rating for MBRS1090HMNG?
The MBRS1090HMNG has a maximum junction temperature (TJ) of 175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows sustained operation in high-ambient environments such as enclosed industrial power supplies or telecom shelves. Derating begins above 75°C ambient depending on PCB copper area and airflow - always verify thermal design using RθJA = 60°C/W and RθJC = 2°C/W values provided for MBRS1090HMNG.
Does MBRS1090HMNG have a guard ring, and what function does it serve?
Yes, MBRS1090HMNG incorporates a guard ring structure as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. This feature enhances edge termination robustness, improving resistance to localized avalanche breakdown during voltage transients - especially beneficial in flyback or forward converter topologies where reflected spikes exceed nominal VRRM. The guard ring eliminates need for external clamping in many mid-power designs.
What is the forward voltage of MBRS1090HMNG at 10 A and 125°C?
The forward voltage of MBRS1090HMNG is 0.71 V at 10 A and 125°C, per the "ELECTRICAL SPECIFICATIONS" table in the official datasheet. This value reflects reduced barrier height at elevated temperature and is critical for thermal stability analysis - lower VF at high temperature helps prevent thermal runaway in parallel configurations. At room temperature (25°C), VF is 0.85 V under identical conditions.
Is MBRS1090HMNG suitable for use in automotive applications?
MBRS1090HMNG is not AEC-Q101 qualified and is not recommended for automotive safety-critical systems per Taiwan Semiconductor's notice stating these products are "not designed for use in medical, life-saving, or life-sustaining applications." While its 175°C TJ rating and robust construction may support under-hood auxiliary power modules, formal automotive qualification requires additional stress testing and documentation not provided for MBRS1090HMNG.
What is the moisture sensitivity level (MSL) of MBRS1090HMNG, and how does it affect assembly?
MBRS1090HMNG has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to reflow. This eliminates pre-bake steps in SMT lines, reduces process time, and avoids potential damage from moisture-induced popcorning. The Level 1 rating is explicitly stated in the "FEATURES" section of the Taiwan Semiconductor datasheet for MBRS1090HMNG.
