Product details
Overview
MBR30100CT-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 (2) package, rated for 100 V reverse voltage, 15 A average forward current per diode leg (30 A total), and 0.85 V max forward voltage at 15 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR30100CT-G1 datasheet, MBR30100CT-G1 pinout, MBR30100CT-G1 application, or MBR30100CT-G1 equivalent, key selection criteria include its dual-diode configuration with common cathode, thermal resistance of 2.5 °C/W (junction-to-case), 200 A non-repetitive surge rating, +150°C junction temperature limit, and RoHS/Green compliance per Diodes' specifications.
Technical Context
This device integrates two independent Schottky diodes sharing a single cathode terminal, enabling synchronous or interleaved rectification topologies. Its guard-ring structure enhances ruggedness against transient stress, while the low VF and high dv/dt capability (10,000 V/μs) support efficient operation in 100–500 kHz switch-mode power supplies.
Designed for medium-voltage DC output stages, it operates up to +150°C junction temperature with 6.0 mA max reverse leakage at +125°C and rated VR. Thermal performance relies on proper heatsinking-minimum pad layout per Diodes' package outlines is required to maintain RθJA ≤ 60 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode leg withstands without breakdown. |
| IF(AV) per leg | 15 A - Continuous average forward current per diode at TC = +107°C; 30 A total device rating. |
| VF (max) | 0.85 V @ 15 A, +25°C - Low conduction loss enabling high-efficiency rectification at typical load conditions. |
| IR (max) | 0.1 mA @ 100 V, +25°C - Minimal leakage ensures low standby power loss in offline PSUs. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance enables effective heat transfer to external heatsink. |
| IFSM | 200 A - Non-repetitive surge current handling capability for line-transient immunity. |
| TJ range | −55°C to +150°C - Wide operating junction temperature supports industrial and automotive-adjacent environments. |
Pinout & Package
Package: TO-220-3 (2), molded plastic case with matte tin–annealed copper leadframe; UL 94V-0 rated, 1.95 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode Leg 1 | Independent anode input for first Schottky diode; connects to primary-side switching node in dual-output or phase-split designs. |
| 2 (K) | Common Cathode | Shared cathode output node; routes combined rectified current to output capacitor/bus; requires low-inductance PCB routing. |
| 3 (A2) | Anode Leg 2 | Independent anode input for second Schottky diode; enables dual-channel or center-tapped transformer secondary rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.85 V max @ 15 A, +25°C reduces conduction loss by >30% vs. standard silicon rectifiers at same rating. |
| Guard-ring protection | Integrated edge termination structure prevents premature avalanche failure under voltage transients or localized heating. |
| +150°C TJ operation | Enables use in thermally constrained enclosures without derating below 15 A per leg up to +107°C case temperature. |
| RoHS/Green compliance | Meets EU RoHS 3 (2015/863/EU) and Diodes' halogen/antimony-free definition (<900 ppm Br/Cl, <1000 ppm Sb). |
| High dv/dt immunity | 10,000 V/μs rating suppresses false triggering during fast-switching transitions in resonant converters. |
Applications
| Server PSU Output Rectification | Industrial AC-DC Adapter |
|---|---|
Use Scenario: High-density 1U server power supply delivering 12 V/54 A output using active-clamp forward topology. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing two discrete 15 A devices; common cathode simplifies PCB layout and reduces parasitic inductance. Use Value: 0.85 V VF minimizes conduction loss at full load, improving efficiency by ~0.8% over comparable Si diodes and reducing heatsink size by 25%. | Use Scenario: 48 V/10 A industrial control power module operating continuously at +70°C ambient. IC Role / Device Role / Timing Role: Secondary-side rectifier in flyback converter with wide-input-range (85–264 VAC) front-end. Use Value: 200 A IFSM rating withstands inrush surges during cold-start; −55°C to +150°C TJ range ensures reliability across extended temperature cycling. |
| LCD TV Power Board | Telecom DC-DC Brick |
Use Scenario: Main 24 V/8 A output stage in LCD TV power board with PFC + LLC cascade architecture. IC Role / Device Role / Timing Role: Synchronous rectification element in LLC secondary, driven by controller timing signals. Use Value: Low noise and fast recovery eliminate EMI spikes near 100–300 kHz switching band, easing EMC filter design. | Use Scenario: 12 V/20 A isolated DC-DC brick for 5G base station remote radio units (RRUs). IC Role / Device Role / Timing Role: Dual-anode rectifier supporting redundant or split-rail outputs with shared cathode return path. Use Value: Common-cathode configuration reduces component count vs. two separate TO-220 diodes, saving 12 mm² PCB area and lowering assembly cost. |
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-30CPH01-M3/45 | Same 100 V VRRM, 15 A/leg, but TO-247AC package; RθJC = 1.7 °C/W (lower thermal resistance). | Better suited for higher-power designs requiring >30 W dissipation; larger footprint and higher cost. | Select when thermal budget is tight and heatsink space allows TO-247 mounting. |
| ON Semiconductor MBR30100CT | Identical electrical specs and TO-220-3 (2) package, but non-Green (halogenated) molding compound and no antimony-free certification. | Acceptable where RoHS 3 and "Green" compliance are not mandated (e.g., legacy industrial equipment). | Choose only if green compliance is waived in BOM and procurement allows non-Diodes branding. |
Compared with VS-30CPH01-M3/45 and MBR30100CT, the MBR30100CT-G1 offers optimal balance of thermal performance (2.5 °C/W), RoHS 3/Green compliance, and TO-220 footprint compatibility-making it preferred for new designs targeting energy efficiency standards and environmental certifications.

FAQ
What is the maximum allowable case temperature for continuous operation?
The MBR30100CT-G1 supports continuous operation up to +107°C case temperature while maintaining 15 A average forward current per diode leg, as specified in the Absolute Maximum Ratings table. Exceeding this requires linear derating per Figure 3 in DS36946 Rev. 4-2, with zero current at +150°C junction temperature.
Can this part be used in surface-mount designs?
No-MBR30100CT-G1 is only offered in through-hole TO-220-3 (2) packaging and is not compatible with SMT reflow or wave soldering. For surface-mount alternatives, consider Diodes' APD30100QCT-G1 (PowerDI5060) or Vishay's VSKT32A10-M3/45 (TO-252AA).
Does the common cathode configuration support independent control of each anode?
Yes-the A1 and A2 terminals are electrically isolated anodes sharing only the K (cathode) terminal. This allows independent connection to separate transformer secondaries, switching nodes, or control paths, enabling dual-output, interleaved, or redundancy configurations without internal coupling.
Is thermal pad soldering required for reliable operation?
Yes-Diodes specifies that the TO-220-3 (2) package must be mounted on a heatsink using minimum recommended copper pad layout per their package outline documentation. Omitting thermal pad soldering or undersized copper pour increases RθJA beyond 60 °C/W, risking thermal runaway at rated current.
