Product details
Overview
MBR20100CD-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-252-2 (DPAK) package, rated for 100 V reverse voltage and 10 A average forward current per diode leg, with maximum forward voltage of 0.85 V at +25°C and leakage current ≤0.1 mA. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR20100CD-G1 datasheet, MBR20100CD-G1 pinout, MBR20100CD-G1 application, or MBR20100CD-G1 equivalent, this device is selected for medium-voltage, high-efficiency power conversion where thermal performance (RθJC = 2.0 °C/W), surge robustness (IFSM = 150 A), and RoHS-compliant "Green" packaging are critical design requirements.
Technical Context
This dual common-cathode Schottky rectifier integrates two independent 100 V/10 A diode elements sharing a single cathode terminal, enabling synchronous or interleaved output configurations in dual-rail or redundant power supplies. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for operation up to +150°C junction temperature, it supports high-frequency switching (>100 kHz) with minimal reverse recovery charge (Qrr not specified but inherently near-zero for Schottky topology) and dv/dt capability of 10,000 V/µs - critical for EMI-sensitive DC-DC converters and AC-DC front-ends.
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 bus applications. |
| IF(AV) | 10 A per diode - Continuous DC output current capability at TC = +122°C; enables compact heatsink design in 100–200 W SMPS. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss reduces power dissipation by ~25% vs. standard silicon rectifiers at same current. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Ultra-low leakage preserves efficiency in standby and light-load conditions. |
| IFSM | 150 A - Non-repetitive surge rating allows reliable handling of inrush and fault currents without bond-wire fusing. |
| RθJC | 2.0 °C/W - Low junction-to-case thermal resistance enables direct mounting to PCB copper pour or small heatsinks. |
| TJ max | +150°C - Extended junction temperature rating supports operation in sealed enclosures or high-ambient industrial environments. |
Pinout & Package
MBR20100CD-G1 uses the TO-252-2 (DPAK) surface-mount package: 3-terminal configuration with anode-anode-cathode layout; molded plastic body, matte tin-plated copper leadframe, and RoHS-compliant "Green" compound (halogen/antimony-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A1) | First diode anode | Connects to first input rail (e.g., primary-side transformer secondary winding or buck converter switch node). |
| Pin 2 (Anode A2) | Second diode anode | Connects to second independent input rail (e.g., auxiliary winding or second-phase output in interleaved design). |
| Pin 3 (Cathode K) | Common cathode | Single output node for combined DC output; requires wide copper pour for thermal and current handling. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.85 V @ 10 A, +25°C - Reduces conduction loss to <8.5 W per diode at full load, improving system efficiency by ≥1.5% in 12 V/10 A outputs. |
| Guard-ring protected junction | Enhanced edge termination - Increases avalanche ruggedness and prevents premature breakdown under voltage transients in unregulated inputs. |
| High surge current rating | 150 A non-repetitive peak - Survives cold-start surges and short-circuit events without degradation in 48 V telecom or server PSUs. |
| +150°C operating junction temperature | Rated continuous operation - Enables use in thermally constrained spaces (e.g., enclosed LED drivers or industrial PLC power modules) without derating. |
| Pb-free & "Green" packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A Tier 1 reporting and EU RoHS 2 compliance for global OEM shipments. |

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-M3/5BT | Same 100 V/10 A rating, but TO-263-2 package (RθJC = 2.0 °C/W); VF = 0.82 V @ 10 A, +25°C; IR = 0.15 mA. | Requires larger PCB pad area; better suited for forced-air-cooled systems due to higher thermal mass. | Select when board space permits larger D2PAK and airflow is available for enhanced thermal margin. |
| ON Semiconductor MBR20100CT-G | TO-220-3 through-hole variant; identical electrical specs; RθJC = 2.5 °C/W; 1.9 g weight vs. 0.31 g for TO-252-2. | Requires wave soldering and mechanical mounting; unsuitable for high-vibration environments. | Choose only for legacy through-hole designs or prototyping where manual assembly is preferred over SMT reflow. |
Compared with VS-20BQ100-M3/5BT and MBR20100CT-G, MBR20100CD-G1 offers optimal balance of ultra-low profile, automated assembly compatibility, and thermal performance in space-constrained SMT power supplies - especially where weight, vibration resistance, and reflow process control are prioritized.

FAQ
Is MBR20100CD-G1 suitable for synchronous rectification circuits?
No - MBR20100CD-G1 is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET controller. It functions as a diode-based freewheeling or output rectifier. For synchronous rectification, a dedicated gate driver IC (e.g., Diodes APW7200) paired with low-RDS(on) MOSFETs is required. This part replaces conventional PN diodes to reduce losses but does not provide active switching control.
What is the recommended PCB pad layout 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 Pin 3 (cathode), with 2.5 mm width for Pins 1 and 2 (anodes), and 2.1 mm spacing between pads. A 1.5 mm thermal relief gap between cathode pad and internal ground planes is advised to balance solderability and thermal transfer.
Does MBR20100CD-G1 have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, MBR20100CD-G1 has no minority-carrier storage and therefore no defined reverse recovery time. Its switching behavior is governed by junction capacitance (Cj ≈ 220 pF typical at 4 V) and series inductance, enabling clean turn-off with negligible switching loss or ringing in high-frequency converters.
Can MBR20100CD-G1 be used in automotive applications?
Not qualified per AEC-Q101 - MBR20100CD-G1 is rated for industrial temperature range (–65°C to +150°C) but lacks automotive-specific qualification, including PPAP documentation, zero-defect screening, and extended reliability testing. For automotive 12 V/48 V systems, Diodes' AEC-Q101-qualified alternatives like SB20100L-G are recommended instead.
