Product details
Overview
MBRF20200CT-LJ from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in ITO-220AB (Type BR) package, rated for 200V peak reverse voltage, 0.89V max forward voltage at 10A/25°C, and 0.1mA max leakage current at 200V/25°C; used as polarity protection and freewheeling diode in DC power supplies and motor drives.
For engineers reviewing the MBRF20200CT-LJ datasheet, MBRF20200CT-LJ pinout, MBRF20200CT-LJ application, or MBRF20200CT-LJ equivalent, key selection criteria include per-leg 10A average forward current, 170A non-repetitive surge rating, thermal resistance of 5°C/W (junction-to-case), AEC-Q101 qualification, and RoHS-compliant matte tin finish on copper leadframe.
Technical Context
This dual-diode Schottky rectifier integrates two independent 200V/10A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional freewheeling paths. Its guard ring die construction provides transient overvoltage protection without external snubbers.
Designed for high-efficiency switching power conversion, it operates across –55°C to +175°C with low conduction loss (0.75V typ at 10A/125°C) and minimal reverse recovery charge-critical for reducing EMI and improving thermal performance in compact 12–48V industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage per leg; defines safe DC bus voltage margin in 48V systems. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg at TA = 25°C; total device rating is 20A with shared cathode. |
| VF (max) | 0.89 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V output buck converters. |
| IR (max) | 0.1 mA @ 200V, 25°C - Minimal leakage preserves battery standby time in always-on automotive modules. |
| IFSM | 170 A - Peak surge capability supports motor startup transients and capacitor inrush without failure. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance for ITO-220AB package; enables 12W dissipation with 60°C case rise. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive under-hood applications including temperature cycling and HTRB. |
Pinout & Package
MBRF20200CT-LJ uses the ITO-220AB (Type BR) thermally enhanced plastic package with three terminals: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Mounting tab is electrically connected to cathode and serves as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode for first diode leg | Connects to positive input rail in dual-input OR-ing configuration or to inductive load terminal in freewheeling path. |
| Pin 2 (Cathode) | Common cathode node | Electrically tied to mounting tab; must be thermally bonded to heatsink and referenced to system ground or output return. |
| Pin 3 (Anode 2) | Input anode for second diode leg | Enables independent control of two current paths sharing one output node-e.g., redundant power inputs or dual-phase flyback clamp. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, eliminating need for external TVS in 24V industrial PLC I/O modules. |
| Low VF (0.75V typ @ 125°C) | Maintains efficiency in high-ambient environments like enclosed motor drive enclosures without derating. |
| AEC-Q101 qualification | Validates reliability for automotive body control modules operating at 125°C ambient with 1000-cycle temperature cycling. |
| Halogen- and antimony-free "Green" compound | Meets IPC-1752A material declaration requirements for Tier 1 automotive supply chain traceability. |
| Matte tin annealed finish | Ensures consistent solder wetting and intermetallic formation during reflow, critical for high-yield SMT assembly of power boards. |
Applications

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-20CPH02-M3 | Same 200V/20A rating but TO-247AC package; RθJC = 2.5°C/W; VF = 0.87V @ 10A. | Better thermal performance for high-power density designs; larger footprint and higher cost. | Select when junction temperature must stay <130°C at 15A continuous with limited heatsink area. |
| ON Semiconductor MBR20200CTG | Identical TO-220AB package and electrical specs; AEC-Q101 qualified; same 0.89V VF max. | Drop-in replacement with identical pinout and thermal profile; slightly higher IR (0.2mA). | Choose for multi-source procurement strategy where Diodes Inc. supply continuity is constrained. |
Compared with VS-20CPH02-M3, MBRF20200CT-LJ trades 2.5°C/W thermal advantage for 35% smaller PCB footprint; versus MBR20200CTG, it offers tighter IR spec (0.1mA vs 0.2mA) critical for low-power sleep modes in battery-backed systems.

FAQ
Is MBRF20200CT-LJ pin-compatible with MBR20200CT-LJ?
Yes-both share identical ITO-220AB (MBRF) and TO-220AB (MBR) packages respectively, but differ in thermal resistance (5°C/W vs 3°C/W) and mounting tab isolation. MBRF20200CT-LJ's tab is cathode-connected; MBR20200CT-LJ's tab is also cathode-connected, so PCB layout remains identical. Mechanical dimensions match per Diodes' package outlines DS36513 Rev. 7.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +175°C, and the device is rated for continuous operation up to this limit when thermal design ensures RθJA ≤ 25°C/W. At 10A per leg and 0.85V VF, power dissipation is 8.5W; with RθJC = 5°C/W and a 40°C heatsink, junction temperature reaches 145°C-within safe margin.
Does MBRF20200CT-LJ support reflow soldering per J-STD-020?
Yes-it is qualified for moisture sensitivity level 1 (MSL-1), meaning unlimited floor life and compatibility with standard Pb-free reflow profiles (peak 260°C). The matte tin annealed finish and green molding compound ensure reliable wetting and no popcorning during JEDEC-standard reflow cycles.
Can this device replace a fast recovery diode in a PFC boost stage?
No-Schottky diodes like MBRF20200CT-LJ lack sufficient reverse voltage ruggedness for PFC stages operating near 400V DC bus. Their 200V VRRM rating makes them suitable only for secondary-side rectification (e.g., 12V/24V/48V outputs), not primary-side boost diodes where 600V+ fast recovery or SiC devices are required.
