Product details
Overview
MBRS10100 from Taiwan Semiconductor is a 10A, 100V Schottky barrier surface-mount rectifier in TO-263AB (D2PAK) package, optimized for high-efficiency DC/DC conversion with 0.85V forward voltage at 10A and 25°C, 5mA reverse leakage at 100V and 125°C, and 120A surge capability-used in compact switching power supplies and AC adapters.
For engineers reviewing the MBRS10100 datasheet, MBRS10100 pinout, MBRS10100 application, or MBRS10100 equivalent, key selection criteria include its 100V VRRM, 10A continuous forward current, 2°C/W junction-to-case thermal resistance, TO-263AB thermal performance, and suitability for high-frequency SMPS where low conduction loss and fast recovery are critical.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 10,000 V/μs dv/dt rating supports robust operation in noisy switching environments.
Designed for surface-mount assembly, it meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, enabling reflow compatibility without baking. Junction temperature range spans –55°C to +175°C, supporting industrial and automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC flyback or buck output stages |
| IF | 10 A - Continuous average forward current; determines heatsink sizing and PCB copper area requirements |
| IFSM | 120 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overload events |
| VF @ 10A, 25°C | 0.85 V - Forward voltage drop; directly impacts conduction loss (Pcond ≈ 8.5 W at full load) |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables direct thermal coupling to heatsink or copper pour for thermal management |
| IR @ 100V, 125°C | 5 mA - Reverse leakage current; affects standby power and thermal runaway risk in high-temp operation |
Pinout & Package
Package: TO-263AB (D2PAK), 3-terminal surface-mount package with exposed cathode tab for thermal and electrical connection. Cathode marked by polarity symbol on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Soldered to input rail or switch node; carries full load current into device |
| Cathode (Tab & Lead 2) | Output current exit / common return | Exposed metal tab serves as primary thermal path and low-inductance return; must be connected to ground or output plane |
| NC / Dummy (Lead 3) | Structural support only | No internal connection; mechanical anchor for leadframe stability-must not be electrically tied |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Prevents premature avalanche breakdown at edge regions, improving reliability under voltage transients |
| Moisture Sensitivity Level 1 | Zero bake requirement before reflow; compatible with standard SMT lines without dry-pack handling |
| Halogen-free per IEC 61249-2-21 | Meets environmental compliance for RoHS and green manufacturing without compromising flame retardancy |
| Junction-to-case RθJC = 2°C/W | Enables >75% of heat to transfer directly from die to heatsink or PCB copper, reducing thermal bottleneck |
Applications

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-MBR10100CT | TO-220AC package, dual common-cathode configuration; 0.82V VF @ 10A, 25°C; 100V VRRM | Requires through-hole mounting and separate cathode routing; better for discrete layout but larger footprint | Choose when board space permits through-hole and dual-output rectification is needed |
| ON Semiconductor MBR10100CT | TO-220AB package, single-diode version available; 0.84V VF @ 10A, 25°C; same 100V rating | Lacks guard ring; lower dv/dt rating (5,000 V/μs); no J-STD-020 MSL-1 certification | Acceptable for cost-sensitive consumer designs where transient immunity and reflow simplicity are secondary |
Compared with VS-MBR10100CT and MBR10100CT, MBRS10100 offers superior surface-mount integration, guaranteed MSL-1 handling, guard ring protection, and lower thermal resistance-making it preferred for high-density, thermally constrained, or automotive-qualified power designs.

FAQ
What is the maximum junction temperature rating for MBRS10100?
The MBRS10100 has a maximum junction temperature (TJ) of +175°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial environments or under sustained 10A load with appropriate thermal design. The MBRS10100's 2°C/W RθJC enables effective heat transfer to external copper or heatsinks, maintaining safe junction temperatures even at elevated ambient conditions.
Does MBRS10100 have a guard ring structure?
Yes, the MBRS10100 incorporates a guard ring for overvoltage protection, explicitly stated in its features list. This design mitigates edge breakdown under high dv/dt or transient conditions, enhancing ruggedness in switching applications such as flyback or forward converters. The guard ring contributes to the device's 10,000 V/μs critical rate of rise of off-state voltage rating.
Is MBRS10100 RoHS and halogen-free compliant?
Yes, MBRS10100 is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the official datasheet features section. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These qualifications make MBRS10100 suitable for environmentally regulated end equipment including computing and industrial automation systems.
What is the reverse leakage current of MBRS10100 at 100V and 125°C?
The reverse leakage current (IR) of MBRS10100 is specified as 5 mA maximum at rated VR = 100V and junction temperature of 125°C. This value is critical for estimating standby power loss in high-temperature operation and appears in the Electrical Specifications table under "Reverse current @ rated VR" with note (2). It reflects real-world thermal stress performance beyond room-temperature specs.
Can MBRS10100 be used in place of MBRS1090 or MBRS10150?
MBRS10100 is not a direct replacement for MBRS1090 (90V) or MBRS10150 (150V) due to differing VRRM ratings-each part is optimized for its specific voltage class. While pin-compatible and identical in package and thermal performance, substituting MBRS10100 for MBRS10150 risks reverse breakdown in 150V circuits. Always verify system peak reverse voltage against the exact MBRS10100 100V rating before substitution.
