Product details
Overview
MBR20100CDTR-E1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-252-2 (DPAK) package, rated for 100 V reverse voltage, 10 A average forward current per diode leg, and 0.85 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency switch-mode power supplies.
For engineers reviewing the MBR20100CDTR-E1 datasheet, MBR20100CDTR-E1 pinout, MBR20100CDTR-E1 application, or MBR20100CDTR-E1 equivalent, key selection criteria include its dual-diode configuration, 150°C junction temperature rating, RoHS-compliant green packaging, and thermal resistance of 2.0°C/W (junction-to-case) in TO-252-2.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 10 A diode elements sharing a single cathode terminal. Its guard-ring structure enhances ruggedness against transient overvoltage stress, while the low VF enables high-efficiency rectification in medium-voltage DC-DC converters.
The device operates up to +150°C junction temperature with 150 A non-repetitive surge capability and exhibits <0.1 mA reverse leakage at +25°C under rated DC blocking voltage - critical for maintaining efficiency in standby and light-load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode withstands without breakdown; defines usable input voltage range in buck or flyback outputs. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +122°C; supports 20 A total output in dual-leg parallel configurations. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss reduces heat generation and improves system efficiency in high-current, high-frequency SMPS. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal reverse leakage preserves regulation accuracy and minimizes standby power loss. |
| RθJC | 2.0 °C/W - Junction-to-case thermal resistance in TO-252-2 package; enables effective heatsinking via PCB copper area per recommended pad layout. |
| TJ(max) | +150°C - Maximum operating junction temperature; allows reliable operation in thermally constrained industrial power modules. |
| IFSM | 150 A - Non-repetitive peak surge current handling; sustains inrush events during cold-start or output capacitor charging. |
Pinout & Package
MBR20100CDTR-E1 uses the TO-252-2 (DPAK) surface-mount package with three terminals: Anode 1 (A1), Anode 2 (A2), and common Cathode (K). The package features matte tin-plated copper leadframe, halogen/antimony-free green molding compound (UL 94V-0), and weighs 0.31 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode Leg 1 | Input connection for first rectifier path; electrically isolated from A2 but shares K terminal. |
| A2 | Anode of Diode Leg 2 | Input connection for second independent rectifier path; enables dual-output or phase-interleaved topologies. |
| K | Common Cathode | Shared output node for both diodes; simplifies PCB routing and thermal management in center-tapped or dual-winding designs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual common-cathode Schottky structure | Enables compact dual-output rectification without discrete cathode paralleling; reduces component count in multi-rail PSUs. |
| Guard-ring protected junction | Improves ruggedness against dv/dt-induced avalanche and ESD transients (MM >400 V, HBM >8000 V), enhancing field reliability. |
| Pb-free, "Green" RoHS-compliant construction | Meets EU Directive 2011/65/EU with <900 ppm Br/Cl and <1000 ppm Sb; eliminates hazardous substances without sacrificing thermal performance. |
| Low RθJC (2.0°C/W) | Allows efficient heat transfer to PCB copper pour; supports 10 A continuous operation with minimal heatsink area in TO-252-2 footprint. |
| High surge current rating (150 A IFSM) | Withstands repeated cold-start surges in AC-DC adapters and server VRMs without degradation or bond-wire fusing. |
Applications
| Server VRM Output Rectification | Industrial AC-DC Adapter |
|---|---|
|
Use Scenario: High-current, high-efficiency 12 V output stage in multi-phase server voltage regulator modules. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacement; provides low-VF, fast-recovery rectification for interleaved phases. Use Value: Reduces conduction loss by ~30% vs. standard silicon diodes, lowering MOSFET drive burden and improving full-load efficiency above 92%. |
Use Scenario: Secondary-side rectification in 48 V/5 A industrial AC-DC power supplies with tight thermal constraints. IC Role / Device Role / Timing Role: Dual-anode, common-cathode rectifier enabling independent winding utilization on center-tapped transformer. Use Value: Eliminates need for two separate diodes and associated layout complexity while maintaining 100 V isolation margin and 150°C thermal headroom. |
| Telecom DC-DC Converter | Medical Power Supply Output Stage |
|
Use Scenario: 48 V input to 3.3 V/5 V point-of-load conversion in telecom shelf power systems. IC Role / Device Role / Timing Role: High-frequency rectifier in forward or active-clamp flyback topology operating at 300–500 kHz. Use Value: Low reverse recovery charge (Qrr ≈ 0 nC) prevents switching node ringing and EMI spikes, easing EMC compliance. |
Use Scenario: Isolated auxiliary supply rectification in Class II medical devices requiring reinforced insulation and low leakage. IC Role / Device Role / Timing Role: Dual-leg output rectifier delivering two independent low-noise rails (e.g., +5 V logic and +3.3 V analog). Use Value: <0.1 mA IR at +25°C ensures negligible standby current draw, supporting energy-efficient sleep modes per IEC 60601-1 leakage limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20BQ100-M3/45 | Same 100 V / 2×10 A rating, but TO-263-2 package (RθJC = 2.0°C/W); VF = 0.78 V @ 10 A, +125°C. | Higher thermal mass and larger footprint; better suited for forced-air-cooled industrial modules than space-constrained DPAK layouts. | Select when board-level airflow or higher surge margin (200 A IFSM) justifies larger package and cost premium. |
| ON Semiconductor MBR20100CT | TO-220-3 through-hole variant; identical electrical specs but RθJC = 2.5°C/W and higher mounting complexity. | Requires vertical heatsinking and wave-soldering; less suitable for automated SMT lines or ultra-thin power bricks. | Choose only if legacy through-hole assembly infrastructure exists or mechanical retention under vibration is required. |
Compared with VS-20BQ100-M3/45 and MBR20100CT, MBR20100CDTR-E1 offers optimal balance of SMT manufacturability, thermal performance in minimal footprint, and cost-effective tape-and-reel delivery - ideal for high-volume, space-sensitive power supply designs.

FAQ
What is the maximum junction temperature and how does it impact thermal design?
The MBR20100CDTR-E1 has a maximum junction temperature of +150°C. This allows operation in thermally demanding environments such as enclosed server chassis or sealed industrial enclosures. Designers must ensure that the junction-to-ambient thermal path - including PCB copper area, solder joint quality, and optional heatsink - keeps TJ below this limit under worst-case load and ambient conditions, using the specified RθJA of 50°C/W for TO-252-2.
Is MBR20100CDTR-E1 suitable for synchronous rectification replacement?
No - MBR20100CDTR-E1 is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, its low VF and zero reverse recovery charge make it an excellent choice where synchronous rectification is impractical due to control complexity or cost, especially in medium-power flyback or forward converters operating up to 500 kHz.
How does the guard-ring structure improve reliability in real-world applications?
The integrated guard ring mitigates edge breakdown under high dv/dt stress and suppresses localized avalanche during transient overvoltage events. In practice, this extends lifetime in switch-mode supplies exposed to line surges or inductive kickback, and improves ESD robustness during handling and assembly - evidenced by MM >400 V and HBM >8000 V ratings confirmed in the datasheet.
What are the recommended PCB pad dimensions for TO-252-2 thermal performance?
Per Diodes' DS36950 Rev. 5, the TO-252-2 pad layout requires a minimum 11.6 mm × 7.0 mm copper pour for the cathode (K) pad, with 2.5 mm wide traces for A1 and A2. Thermal vias (≥6×0.3 mm) should connect the K pad to inner-layer ground planes. This achieves the rated 2.0°C/W RθJC and supports full 10 A per leg continuous current without exceeding +150°C junction temperature.
