Product details
Overview
MBRB20100CT-13 from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO263AB (D2PAK) package, rated for 100V reverse voltage, 0.84V max forward voltage at 10A/25°C, and 0.1mA max leakage current at 100V/25°C; it serves as polarity protection and freewheeling diode in DC-DC converters and industrial power supplies.
For engineers reviewing the MBRB20100CT-13 datasheet, MBRB20100CT-13 pinout, MBRB20100CT-13 application, or MBRB20100CT-13 equivalent, key selection criteria include per-leg 10A average forward current, 150A non-repetitive surge rating, thermal resistance of 5°C/W junction-to-case, RoHS-compliant matte tin finish, and D2PAK footprint compatibility with high-power PCB layouts.
Technical Context
This dual Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous rectification or dual-rail output configurations. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction loss in high-frequency switching topologies.
Rated for continuous operation from –55°C to +175°C, it delivers stable performance under thermal stress with 20°C/W junction-to-ambient resistance on a 2-inch aluminum board. The device meets JEDEC reliability standards and supports automotive-grade variants via Q-suffix derivatives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe DC bus isolation in 48V–72V systems. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg; supports 20A total dual-leg output with shared cathode. |
| VF (max) | 0.84 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V–24V buck converters at full load. |
| IR (max) | 0.1 mA @ 100V, 25°C - Minimal leakage preserves standby power integrity in always-on industrial controllers. |
| IFSM | 150 A - Peak non-repetitive surge current capability; withstands inrush transients in motor drive snubber circuits. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for sustained 10A/leg operation without derating. |
| Package | TO263AB (D2PAK) - Surface-mount package with exposed copper tab for thermal and electrical cathode connection. |
Pinout & Package
TO263AB (D2PAK) package features three terminals: two anodes (A1, A2) and one common cathode (K) on the exposed metal tab. The molded plastic body complies with UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode Leg 1 | Input terminal for first rectifier path; electrically isolated from A2; connects to input rail or switch node. |
| A2 | Anode Leg 2 | Input terminal for second rectifier path; independent conduction path; supports dual-output or phase-split designs. |
| K (Tab) | Common Cathode | Shared output node and primary thermal interface; must be soldered to large copper pour or heatsink for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient robustness without external TVS, reducing BOM count in ruggedized power modules. |
| Low VF (0.72–0.84 V) | Reduces conduction loss by ≥35% vs. standard PN rectifiers at 10A, lowering thermal design margin requirements. |
| RoHS-compliant matte tin finish | Ensures reliable solder wetting and intermetallic formation during lead-free reflow, meeting IPC-J-STD-006B Class 1. |
| Halogen- and antimony-free "Green" compound | Complies with IEC 61249-2-21 and JEDEC JESD201A, supporting eco-design mandates in EU and Asia-Pacific markets. |

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-20CPH06-M3 | Same 100V VRRM, but 20A total (10A/leg); VF = 0.72V typ @ 10A, 125°C; RθJC = 4.5°C/W. | Better thermal performance and lower VF at elevated temperature; tighter VF distribution improves parallel diode matching. | Select when operating above 100°C junction or requiring tighter thermal margins in compact enclosures. |
| ON Semiconductor MBR20100CT | Identical ratings and TO263AB package; IR = 0.2mA max @ 100V/25°C (vs. 0.1mA here); slightly higher RθJA (22°C/W). | Higher leakage may impact ultra-low-power standby modes; otherwise functionally interchangeable in most commercial designs. | Acceptable for cost-sensitive non-automotive applications where 0.1mA leakage is not critical. |
Compared with VS-20CPH06-M3 and MBR20100CT, MBRB20100CT-13 offers superior leakage control and JEDEC-qualified reliability, making it preferred for industrial systems requiring long-term stability and low standby loss-while retaining identical footprint and drive compatibility.

FAQ
What is the maximum junction temperature rating for MBRB20100CT-13?
The device is rated for continuous operation from –55°C to +175°C junction temperature. This allows use in high-ambient environments such as enclosed motor drives or sealed telecom cabinets without forced air cooling, provided thermal resistance to ambient remains within limits defined by PCB copper area and heatsinking.
Is MBRB20100CT-13 suitable for automotive applications?
Standard MBRB20100CT-13 is not AEC-Q200 qualified. Diodes offers automotive-grade equivalents with Q-suffix (e.g., MBRB20100CTQ), which undergo PPAP, are manufactured in IATF 16949 facilities, and meet AEC-Q101 stress testing requirements for discrete semiconductors.
How does the common-cathode configuration affect PCB layout?
The shared cathode (K) is implemented as the exposed metal tab, requiring a single large copper pour connected to the output ground plane. This simplifies routing versus dual separate cathodes, reduces parasitic inductance, and improves thermal transfer-but mandates careful isolation of A1 and A2 traces to avoid shorting to the cathode pad.
What is the recommended solder profile for TO263AB packaging?
Reflow must follow IPC-J-STD-020 Level 1 guidelines: peak temperature ≤260°C, time above 217°C ≤60 seconds, and ramp rate ≤3°C/s. The matte tin annealed finish ensures compatibility with standard lead-free SAC305 profiles, and the 1.6g mass requires adequate preheat to avoid thermal shock cracking.
