Product details
Overview
MBR20100CT-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220F-3 package, rated for 100 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.85 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR20100CT-G1 datasheet, MBR20100CT-G1 pinout, MBR20100CT-G1 application, or MBR20100CT-G1 equivalent, key selection criteria include its dual-diode topology, 150°C junction rating, 150 A non-repetitive surge capability, RoHS/Green compliance, and thermal resistance of 4.5°C/W (junction-to-case) in TO-220F-3.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous or interleaved rectification in dual-rail or center-tapped topologies. Its guard-ring structure enhances ruggedness against transient overvoltage stress.
Designed for medium-voltage, high-frequency power conversion, it operates up to +150°C junction temperature with 10000 V/µs dv/dt rating and exhibits <0.1 mA reverse leakage at +25°C under rated DC blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode can block without breakdown. |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +122°C, defining thermal design margin. |
| VF (max) | 0.85 V @ 10 A, +25°C - Low conduction loss enabling high-efficiency 12–48 V output stages. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal leakage preserves efficiency in standby and light-load conditions. |
| RθJC | 4.5 °C/W - Junction-to-case thermal resistance in TO-220F-3, critical for heatsink sizing. |
| IFSM | 150 A - Non-repetitive surge current handling capability for inrush and fault transients. |
| TJ range | −65°C to +150°C - Wide operating junction temperature supports industrial and automotive-adjacent environments. |

| 2 (K) | Common Cathode | Shared output node; internally connected to metal tab (electrically tied to pin 2). |
| 3 (A2) | Anode of Diode 2 | Input terminal for second rectifier path; electrically isolated from case. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.85 V @ 10 A ensures <8.5 W conduction loss per diode leg at full load. |

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-MBR20100CT | Same 100 V/10 A per leg, but TO-220-3 (non-isolated tab); RθJC = 2.5°C/W. | Requires insulating washer for heatsink mounting; higher thermal performance but less isolation. | Select when maximum thermal efficiency is prioritized and electrical isolation from heatsink is managed externally. |
| ON Semiconductor MBR20100CT | Identical ratings and TO-220F-3 package; minor differences in IR spec (0.15 mA max @ +25°C vs. 0.1 mA). | No functional impact in typical SMPS designs; same footprint and thermal profile. | Drop-in alternative where Diodes' supply chain is constrained; verify date-code traceability for long-term BOM stability. |
Compared with VS-MBR20100CT and ON's MBR20100CT, the MBR20100CT-G1 offers superior electrical isolation via TO-220F-3 insulation and tighter IR control, making it preferred for medical and isolated industrial systems where creepage/clearance and leakage sensitivity matter.

FAQ
What is the thermal interface requirement for MBR20100CT-G1 in TO-220F-3?
The TO-220F-3 package features an insulated tab, so no additional insulator is needed between the device and heatsink. Thermal paste or pad must be applied to the metal tab surface. Mounting torque should be 0.5–0.7 N·m to ensure optimal RθJC of 4.5°C/W without cracking the molded case.
Can MBR20100CT-G1 replace a single-diode Schottky in existing designs?
Yes, but only if the circuit uses a common-cathode configuration and both anodes are independently driven. Its dual-diode structure cannot substitute for a single-anode/single-cathode part without board-level rewiring. Pin 2 (K) must serve as the sole cathode return path.
Is MBR20100CT-G1 qualified for automotive applications?
No - it is not AEC-Q101 qualified. While it meets +150°C TJ and RoHS/Green requirements, Diodes explicitly states automotive use requires separate PPAP-capable, IATF 16949-manufactured variants (e.g., MBR20100CTQ-G1). This part is intended for industrial/computing applications.
How does the guard-ring structure improve reliability?
The integrated guard-ring reduces electric field crowding at the PN junction periphery, suppressing premature avalanche breakdown during voltage transients. This extends lifetime under repeated 150 A surge events and improves ESD robustness - validated at >8 kV HBM and >400 V MM per JEDEC standards.
