Product details
Overview
MBR20100CDTR-G1 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-G1 datasheet, MBR20100CDTR-G1 pinout, MBR20100CDTR-G1 application, or MBR20100CDTR-G1 equivalent, key selection criteria include thermal resistance (RθJC = 2.0 °C/W), surge capability (150 A IFSM), junction temperature rating (+150°C), and RoHS-compliant "Green" packaging with halogen/antimony-free materials.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V / 10 A diode elements in a single surface-mount TO-252-2 package. Its low VF and fast recovery enable high-efficiency rectification in DC-DC converters and offline SMPS secondary-side outputs.
The device features guard-ring protection for enhanced ruggedness under transient stress and supports operation up to +150°C junction temperature. Thermal performance is optimized via low RθJC (2.0 °C/W) and moderate RθJA (50 °C/W) when mounted on recommended PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per diode leg; defines safe operating margin in 48 V–72 V output rails. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +122°C; enables 20 A total dual-leg output in compact layout. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss reduces heat generation and improves efficiency in high-current, high-duty-cycle applications. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal leakage preserves regulation accuracy and standby power in energy-sensitive designs. |
| IFSM | 150 A - Non-repetitive surge current handling; withstands inrush and fault transients without degradation. |
| TJ (max) | +150°C - Extended junction temperature rating allows reliable operation in thermally constrained enclosures or high-ambient environments. |
| RθJC | 2.0 °C/W - Low junction-to-case thermal resistance enables effective heat transfer to heatsink or copper pour, critical for sustained 10 A operation. |
Pinout & Package
MBR20100CDTR-G1 uses the TO-252-2 (DPAK) surface-mount package: 3-terminal configuration with exposed cathode pad for thermal and electrical performance. Package dimensions: 6.5 mm × 9.9 mm × 2.4 mm (L × W × H), with 2.54 mm lead pitch and matte tin-plated copper leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode 1) | Anode of first Schottky diode | Connects to input/high-side node of first rectification path; requires trace width and copper area matching 10 A current capacity. |
| 2 (Cathode) | Common cathode for both diodes | Shared output node; large exposed metal pad provides primary thermal path and low-inductance return path for dual-leg conduction. |
| 3 (Anode 2) | Anode of second Schottky diode | Independent input node enabling dual-output or interleaved rectification; electrically isolated from Anode 1 except through shared cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.85 V max @ 10 A, +25°C - Reduces conduction loss by ~30% vs. standard silicon rectifiers, directly improving converter efficiency. |
| Guard-ring protected junction | Enhanced edge termination - Improves reliability under voltage transients and mechanical stress, extending lifetime in industrial power supplies. |
| High surge current rating | 150 A non-repetitive peak - Supports robust startup and overload tolerance without derating in 24–48 V telecom or server PSUs. |
| Pb-free & "Green" construction | Halogen- and antimony-free, RoHS-compliant - Meets IPC-1752A material declaration requirements and eliminates hazardous substance compliance risk. |
| TO-252-2 thermal performance | RθJC = 2.0 °C/W - Enables >8 W power dissipation with ≤16°C rise above case, supporting high-density SMT layouts without discrete heatsinks. |
Applications

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 = 0.82 V @ 10 A, +25°C. | Larger footprint (10.6 mm × 15.9 mm) and higher mounting height; better suited for forced-air-cooled systems. | Select for higher thermal margin where board space permits; avoid if DPAK footprint or low profile is mandatory. |
| ON Semiconductor MBR20100CT | TO-220-3 through-hole variant; VF = 0.85 V @ 10 A, +25°C; RθJC = 2.5 °C/W; same die but different package. | Requires wave soldering and heatsink mounting; not suitable for fully SMT production or high-vibration environments. | Choose only for legacy through-hole designs or prototyping where manual assembly is acceptable. |
Compared with VS-20BQ100-M3/45 and MBR20100CT, MBR20100CDTR-G1 offers optimal balance of thermal performance, SMT compatibility, and compact DPAK footprint-critical for high-density server and telecom power modules requiring automated assembly.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR20100CDTR-G1 supports continuous operation up to TC = +122°C, as specified in its Absolute Maximum Ratings table. At this case temperature, each diode leg delivers 10 A average forward current. Exceeding +122°C requires derating per the IF(AV) vs. TC curve in Figure 3 of DS36950 Rev. 5–2.
Does the TO-252-2 package require thermal vias under the cathode pad?
Yes. The datasheet specifies a minimum recommended pad layout for TO-252-2 (page 11), including a 11.6 mm × 7.0 mm copper area with ≥4 thermal vias (0.3 mm diameter, spaced ≤2 mm apart) connecting to inner-layer ground or thermal planes. This achieves the rated RθJA = 50 °C/W.
Can MBR20100CDTR-G1 replace a single 20 A Schottky in parallel configurations?
No. It contains two independent 10 A diodes with a common cathode-not a single 20 A device. Parallel use of both anodes for combined 20 A output is invalid due to mismatched VF and thermal coupling. It is intended for dual-rail or interleaved topologies, not current doubling.
Is the "G1" suffix indicative of halogen-free status?
Yes. Per Diodes Incorporated's marking convention and Note 3 in DS36950, "G1" denotes a "Green" package: halogen-free (<900 ppm Br, <900 ppm Cl, <1500 ppm total Br+Cl) and antimony-free (<1000 ppm), compliant with JEDEC JS709B and IEC 61249-2-21.
