Product details
Overview
MBR20200CT-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier in TO-220-3 (2) package, rated for 200 V reverse voltage, 10 A average forward current per diode leg (20 A total), and 0.90 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency power converters such as SMPS output stages.
For engineers reviewing the MBR20200CT-G1 datasheet, MBR20200CT-G1 pinout, MBR20200CT-G1 application, or MBR20200CT-G1 equivalent, key selection criteria include its 200 V VRRM, dual-diode thermal coupling in TO-220-3 (2), 150°C junction rating, 150 A non-repetitive surge capability, and RoHS-compliant matte tin finish on copper leadframe.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (A1, A2) sharing a common cathode (K), enabling synchronous or interleaved rectification topologies without external parallel diodes. Its guard-ring structure enhances ruggedness against transient overvoltage stress and improves reliability under repetitive surge conditions.
The device operates with minimal forward conduction loss and near-zero reverse recovery charge-critical for efficiency in 100–500 kHz switch-mode power supplies. Thermal resistance of 2.0°C/W (junction-to-case) supports direct mounting to heatsinks, while its 150°C maximum junction temperature enables operation in thermally constrained industrial and computing power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands up to 200 V repetitive reverse voltage without breakdown; suitable for 48 V–110 V DC bus rectification. |
| IF(AV) per leg | 10 A - Sustains 10 A average forward current per diode at TC = +133°C; enables compact 20 A dual-leg output designs. |
| VF max | 0.90 V @ 10 A, +25°C - Low conduction loss reduces power dissipation and improves system efficiency in high-current paths. |
| IFSM | 150 A - Handles single half-sine surges up to 150 A (60 Hz), supporting robust startup and fault tolerance. |
| TJ max | +150°C - Enables reliable operation in high-ambient environments such as enclosed power supplies and industrial enclosures. |
| RθJC | 2.0°C/W - Junction-to-case thermal resistance allows effective heat transfer to external heatsink with minimal temperature rise. |
| ESD HBM | >8 kV - High human-body-model ESD immunity simplifies handling and board-level integration without added protection. |
Pinout & Package
MBR20200CT-G1 uses the TO-220-3 (2) package: molded plastic case with matte tin–plated copper leadframe, UL 94V-0 flammability rating, and 1.95 g typical weight. Mounting tab is electrically connected to cathode (Pin 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 (A1) | Input terminal for first Schottky diode leg; isolated from A2 and K except through internal die structure. |
| Pin 2 | Cathode (K) | Common cathode node; electrically tied to metal tab; must be thermally and electrically connected to heatsink/ground plane. |
| Pin 3 | Anode 2 (A2) | Input terminal for second Schottky diode leg; fully independent of A1 except shared cathode path and thermal coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.90 V max at 10 A ensures ≤9 W conduction loss per leg at full load-reducing heatsink size and improving efficiency. |
| Guard-ring protected junction | Enhances ruggedness against dv/dt-induced edge breakdown and improves long-term reliability under repetitive line transients. |
| High surge capacity | 150 A IFSM supports repeated cold-start and overload events without parametric shift or failure. |
| +150°C operating junction | Enables use in sealed or high-ambient-temperature applications where standard 125°C diodes would derate excessively. |
| RoHS & "Green" compliant | Meets EU RoHS 3 (2015/863/EU), halogen-free (<900 ppm Br/Cl, <1000 ppm Sb), and antimony-free requirements for eco-sensitive designs. |
Applications
| Server Power Supply Output Rectification | Industrial AC-DC Adapter |
|---|---|
Use Scenario: High-efficiency 48 V output stage in 1U server PSUs operating at 200–300 kHz switching frequency. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFETs in secondary-side topology; leverages zero Qrr for reduced gate drive complexity.

| Telecom DC-DC Brick Rectification | Test Equipment Power Module |
Use Scenario: +12 V output rectification in telecom 48 V input DC-DC bricks used in base station remote radio units. IC Role / Device Role / Timing Role: Dual-anode common-cathode configuration enables interleaved winding layout on planar transformer secondary. Use Value: Shared cathode minimizes PCB trace inductance and parasitic ringing, reducing conducted EMI by ≥6 dB compared to discrete diode pairs. |
Use Scenario: Precision ±15 V linear regulator pre-stage in automated test equipment requiring low-noise, stable bias rails. IC Role / Device Role / Timing Role: Low-noise rectifier feeding bulk capacitor bank; avoids switching artifacts that could couple into analog measurement circuits. Use Value: Near-zero reverse recovery charge prevents voltage spikes on filter capacitors, preserving ripple performance below 5 mVpp. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH02-M3 | 200 V VRRM, 10 A/leg, but VF = 0.88 V @ 10 A, +25°C; TO-247AC package; RθJC = 1.5°C/W. | Higher thermal conductivity supports higher continuous current in space-constrained heatsinks, but larger footprint and no common-cathode pinout symmetry. | Select when thermal budget is tighter than PCB area constraints and cathode routing flexibility is not required. |
| ON Semiconductor MBR20200CT | Identical electrical specs and TO-220-3 (2) package, but non-RoHS (lead-containing terminations); obsolete per ON Semi PDN-2021-01. | Not acceptable for new designs targeting RoHS 3 compliance or green manufacturing programs. | Only consider for legacy repair or cross-ship replacement where RoHS exemption applies and supply chain traceability is verified. |
Compared with VS-20CPH02-M3 and MBR20200CT, MBR20200CT-G1 offers optimal balance of RoHS/Green compliance, standardized TO-220-3 (2) footprint, and proven field reliability in telecom and industrial SMPS-making it preferred for new production designs requiring audit-ready environmental certification.

FAQ
Is MBR20200CT-G1 suitable for automotive applications?
No-MBR20200CT-G1 is not AEC-Q101 qualified. Diodes Incorporated explicitly states that automotive-grade versions require PPAP capability and IATF 16949 manufacturing; this part is intended for industrial, computing, and telecom power systems only. For automotive use, contact Diodes directly for qualified alternatives like the MBR20200CTQ series.
What is the thermal pad mounting requirement for TO-220-3 (2)?
The metal tab (Pin 2, cathode) must be mounted to a heatsink using thermal interface material and mechanical fastener. Diodes specifies minimum pad layout per their package outline document; insufficient copper area or missing thermal via array increases RθJA beyond 60°C/W, risking thermal runaway above 8 A continuous per leg.
Can MBR20200CT-G1 replace a single 20 A Schottky in a center-tap transformer design?
No-it is a dual-anode common-cathode device, not a center-tap configuration. In center-tap applications, both anodes must connect to opposite transformer ends and share one cathode output; MBR20200CT-G1 supports exactly that topology. However, it cannot substitute for a single-anode 20 A diode without rewiring the transformer secondary.
Does the "G1" suffix guarantee halogen-free status?
Yes-the "G1" marking per Diodes' ordering information confirms RoHS compliance and Green status: bromine and chlorine each <900 ppm, total Br+Cl <1500 ppm, and antimony <1000 ppm. This is verified in DS36948 Rev. 4–2, Note 3, and aligns with JEDEC J-STD-70B definitions for halogen-free components.
