Product details
Overview
MBRF20200CT 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 for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBRF20200CT datasheet, MBRF20200CT pinout, MBRF20200CT application, or MBRF20200CT equivalent, key selection criteria include per-leg 10A average forward current rating, thermal resistance of 5°C/W (junction-to-case), AEC-Q101 qualification, RoHS-compliant matte tin finish, and guard ring die construction for transient robustness.
Technical Context
This dual Schottky rectifier integrates two independent 200V/10A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional clamping. Its low VF minimizes conduction loss in high-frequency switching converters, while the guard ring structure enhances surge immunity against inductive kickback.
Thermal performance is defined by RθJC = 5°C/W (ITO-220AB), requiring heatsinking for sustained 10A operation; leakage remains ≤0.1mA at 200V/25°C and ≤10mA at 200V/125°C, supporting stable blocking in industrial ambient conditions up to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage each leg withstands without breakdown |
| IO (per leg) | 10 A - Continuous average forward current per anode leg at TA = +25°C with heatsink |
| VF (max) | 0.89 V @ 10A, +25°C - Forward voltage drop limiting conduction loss in 12–48V DC systems |
| IR (max) | 0.1 mA @ 200V, +25°C - Low leakage preserves efficiency in standby and light-load modes |
| IFSM | 170 A - Non-repetitive surge current handling capability for motor startup or capacitor charging events |
| RθJC | 5 °C/W - Junction-to-case thermal resistance enabling predictable heatsink sizing for ITO-220AB mounting |
| TJ Range | –55°C to +175°C - Operating junction temperature range supporting under-hood and industrial environments |
Pinout & Package
Package: ITO-220AB (TYPE BR), molded green plastic case with UL 94V-0 rating, matte tin-plated copper leadframe, 1.69g weight. Mounting tab is cathode-connected and electrically active.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier leg | Accepts AC or switched DC input; isolated from Anode 2 and Cathode |
| Cathode (Tab & Lead 2) | Common output node for both legs | Electrically connected to metal tab; requires insulated mounting if not referenced to system ground |
| Anode 2 (Lead 3) | Input terminal for second rectifier leg | Enables dual-input/single-output configuration; fully independent from Anode 1 |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient surge tolerance without external TVS components |
| AEC-Q101 qualification | Validates reliability for automotive body electronics and under-hood power modules |
| Low VF (0.89V max @ 10A) | Reduces power loss by ≥30% vs. comparable silicon rectifiers in 12V/24V systems |
| Halogen- and antimony-free "Green" compound | Meets IPC-1752A material declaration requirements for eco-conscious OEMs |
| Lead-free, RoHS-compliant finish | Enables compatibility with Pb-free reflow profiles and eliminates post-solder cleaning |
Applications
| DC Power Supply Input Stage | Motor Drive Freewheeling |
|---|---|
Use Scenario: Input rectification in 24V/48V offline switch-mode power supplies with PFC front-end. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing low-loss AC-to-DC conversion with shared cathode output.

IC Role / Device Role / Timing Role: Common-cathode dual anode configuration enables compact placement across H-bridge outputs. Use Value: Guard ring structure withstands 170A IFSM surges during motor commutation, eliminating need for snubbers. |
| Polarity Protection Circuit | Industrial PLC I/O Module |
Use Scenario: Reverse-voltage protection on 24V DC input rails of programmable logic controllers. IC Role / Device Role / Timing Role: Anode 1 serves as main input path; Anode 2 unused or tied to auxiliary rail. Use Value: 0.1mA IR at 200V ensures <25μW standby dissipation, critical for always-on control modules. | Use Scenario: Output stage protection in 24V digital output modules driving solenoids and valves. IC Role / Device Role / Timing Role: Recirculating diode clamping inductive kickback from 2A–10A loads. Use Value: RθJC = 5°C/W allows direct tab-mounting to PCB copper pour, eliminating discrete heatsinks. |
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-20BQ020TRPBF | Same 200V/10A per leg, but TO-220AC package (RθJC = 3°C/W); VF = 0.82V typ @ 10A | Better thermal performance but lacks AEC-Q101 qualification; no guard ring | Select when higher thermal margin is needed and automotive qualification is not required |
| ON Semiconductor MBR20200CTG | Identical TO-220AB mechanical outline, same electrical specs, but RoHS-compliant only (not "Green" or AEC-Q101) | Lower cost alternative where halogen-free and automotive reliability are not mandated | Select for commercial-grade industrial power supplies with cost-sensitive BOMs |
Compared with VS-20BQ020TRPBF and MBR20200CTG, MBRF20200CT uniquely combines AEC-Q101 qualification, guard ring transient hardening, and halogen-free packaging-making it the only choice for automotive body control modules requiring all three attributes.

FAQ
What is the maximum continuous current per leg for MBRF20200CT?
The MBRF20200CT supports 10A average forward current per leg at TA = +25°C with appropriate heatsinking. At elevated ambient temperatures, derating is required per Figure 4 in DS36513 - e.g., 6.5A at +85°C ambient with ITO-220AB mounted on a 45mm × 20mm × 12mm heatsink.
Is the metal tab electrically isolated from the leads?
No - the metal tab is internally connected to the common cathode (Lead 2). It is not electrically isolated and must be treated as a live terminal. Insulated mounting hardware or isolation pads are required if the heatsink is grounded or at a different potential than the cathode net.
Does MBRF20200CT support surface-mount assembly?
No - the ITO-220AB (TYPE BR) package is through-hole only, with three gull-wing leads designed for wave or selective soldering. It does not have SMD-compatible footprint or thermal pad geometry; no official reflow profile is published by Diodes Incorporated.
How does the guard ring construction improve reliability?
The guard ring die structure surrounds the active junction to suppress edge breakdown during voltage transients, increasing surge immunity. This allows the device to survive 170A non-repetitive surges (IFSM) without degradation - critical for inductive load switching in motor drives and power tools.
