Product details
Overview
MBRF20100CT-JT from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in ITO-220AB package, rated for 100V peak reverse voltage, 0.84V max forward voltage at 10A/25°C, and 0.05mA max leakage current at 100V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBRF20100CT-JT datasheet, MBRF20100CT-JT pinout, MBRF20100CT-JT application, or MBRF20100CT-JT equivalent, key selection criteria include per-leg thermal resistance (5°C/W junction-to-case), surge rating (150A IFSM), AEC-Q101 qualification, RoHS/Green compliance, and ITO-220AB mounting compatibility with standard heatsinks.
Technical Context
This dual Schottky rectifier integrates two independent 10A-rated anode terminals sharing a common cathode, enabling synchronous half-wave rectification or bidirectional clamp operation. Its guard ring die construction provides transient overvoltage immunity, while low VF minimizes conduction loss in high-frequency switching converters.
Thermal performance is defined by RθJC = 5°C/W (ITO-220AB) and RθJA = 20°C/W (unheatsinked), requiring mechanical mounting to external heatsinks for sustained 20A total current. It operates across –55°C to +175°C junction temperature range and meets AEC-Q101 stress testing for automotive under-hood use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in DC bus clamp or flyback snubber circuits. |
| IO (per leg) | 10 A - Continuous average forward current per anode; supports 20A total dual-leg output in balanced load configurations. |
| VF (max) | 0.84 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V–48V SMPS outputs; derates to 0.72V at 125°C. |
| IR (max) | 0.05 mA @ 100V, 25°C - Minimal leakage preserves battery standby time in polarity protection applications. |
| IFSM | 150 A @ 8.3ms - Withstands motor startup surges and capacitor inrush without degradation. |
| RθJC | 5 °C/W - Junction-to-case thermal resistance for ITO-220AB; dictates minimum heatsink size for 20A continuous operation. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab (non-conductive mounting surface), 1.69g mass, UL 94V-0 molded plastic body, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier leg | Accepts AC or pulsed DC input; connects to transformer secondary or H-bridge leg in recirculation path. |
| Cathode (Lead 2) | Common output node for both legs | Shared return path; must be routed with low-inductance trace to minimize switching noise in high-dI/dt applications. |
| Anode 2 (Lead 3) | Input terminal for second rectifier leg | Enables dual-input configuration (e.g., dual supply rails or complementary phase inputs) without external parallel diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient immunity (IEC 61000-4-2 Level 4 compatible) without external TVS components in industrial control inputs. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling (–55°C to +175°C), humidity, and mechanical shock. |
| RoHS & Halogen-free "Green" status | Meets EU Directive 2011/65/EU and contains <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant for export-controlled and medical-grade assemblies. |
| Low RθJC (5°C/W) | Enables compact heatsink design: 45mm × 20mm × 12mm heatsink suffices for full 20A continuous operation at 75°C ambient. |
Applications
| DC Power Supply Polarity Protection | Brushless DC Motor Recirculation |
|---|---|
Use Scenario: Prevents damage from reverse battery connection in 24V industrial power modules. IC Role / Device Role / Timing Role: Series-connected Schottky rectifier placed between battery input and main DC bus.

IC Role / Device Role / Timing Role: Dual-anode topology allows interleaved input filtering from dual DC feeds or backup batteries. Use Value: 0.05mA IR at 100V ensures <1μA standby drain per leg - critical for >10-year shelf life in network infrastructure. |
Use Scenario: Reverse-voltage protection for LIN bus transceivers and window lift motor drivers in passenger compartments. IC Role / Device Role / Timing Role: Mounted directly on PCB with insulated tab, eliminating isolation washers and reducing BOM count. Use Value: AEC-Q101 qualification and –55°C to +175°C operation ensure reliability across all vehicle lifecycle conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20H100CG | Same 100V/20A rating, but TO-247AC package; RθJC = 2.5°C/W; VF = 0.82V @ 10A/25°C. | Higher thermal performance suits higher ambient (>85°C) or unheatsinked designs; larger footprint requires PCB rework. | Select when junction temperature margin is critical and board space permits TO-247 layout. |
| VB20100C-E3/4W | ITO-220AB package, same pinout; VF = 0.85V @ 10A/25°C; IR = 0.1mA @ 100V/25°C; no AEC-Q101. | Lacks automotive qualification; higher leakage reduces suitability for battery-backed systems. | Acceptable for commercial-grade 24V power supplies where cost is prioritized over automotive reliability. |
Compared with STPS20H100CG and VB20100C-E3/4W, MBRF20100CT-JT uniquely balances AEC-Q101 compliance, ITO-220AB insulation, and 0.05mA leakage - making it optimal for automotive and long-life industrial power interfaces where safety certification and low standby loss are mandatory.

FAQ
What is the maximum junction temperature for continuous operation?
The MBRF20100CT-JT has a specified operating junction temperature range of –55°C to +175°C. For continuous 20A total current, thermal design must ensure TJ remains ≤175°C, requiring heatsinking per the 5°C/W RθJC spec - typically achieved with a 45mm × 20mm × 12mm aluminum heatsink at ≤75°C ambient.
Is the ITO-220AB package electrically isolated?
Yes - the ITO-220AB package features an electrically insulated metal tab, allowing direct mounting to grounded chassis or heatsinks without shorting the cathode terminal. This eliminates the need for insulating washers or pads, simplifying mechanical assembly and improving thermal transfer reliability.
How does the guard ring construction improve reliability?
The guard ring die structure surrounds the active junction to suppress edge breakdown under high dv/dt or transient overvoltage events. It enables the device to withstand repetitive 150A surge currents and meet IEC 61000-4-2 ESD immunity requirements without external protection components in industrial control inputs.
Can MBRF20100CT-JT replace MBR20100CT in existing designs?
Yes - MBRF20100CT-JT is a direct alternate to MBR20100CT with identical electrical specs and pinout, differing only in package (ITO-220AB vs. TO-220AB). The insulated tab enables safer mounting in grounded systems, but thermal resistance is higher (5°C/W vs. 2°C/W), so heatsink sizing must be re-evaluated for full-load operation.
