Product details
Overview
MBR20100CT-LJ from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 100V peak reverse voltage, with max 0.84V forward voltage at 10A/25°C and 0.05mA leakage at 100V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive flyback circuits.
For engineers reviewing the MBR20100CT-LJ datasheet, MBR20100CT-LJ pinout, MBR20100CT-LJ application, or MBR20100CT-LJ equivalent, key selection criteria include per-leg 10A average forward current, thermal resistance (2°C/W junction-to-case), AEC-Q101 qualification, RoHS/Green compliance, and TO-220AB mechanical mounting compatibility.
Technical Context
This dual Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, 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.
Designed for commercial-grade reliability, it operates from –55°C to +175°C with 150A non-repetitive surge rating and meets AEC-Q101 stress testing for automotive under-hood environments. Thermal performance is optimized for direct heatsink mounting via the metal tab (cathode-connected).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 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 anode leg at TC = 100°C; supports 20A total dual-leg output with shared cathode. |
| VF (max) | 0.84 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V–48V SMPS outputs. |
| IR (max) | 0.05 mA @ 100V, 25°C - Minimal leakage preserves battery standby time in always-on power rails. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance enables 10W dissipation with ≤20°C temperature rise above heatsink. |
| IFSM | 150 A - Single half-sine surge rating allows robust handling of motor startup inrush or capacitor charging spikes. |
| TJ range | –55°C to +175°C - Extended operating range supports under-hood automotive and industrial ambient conditions. |
Pinout & Package
TO-220AB package with isolated metal tab (cathode-connected), 3-terminal configuration: Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2. Mounting tab electrically tied to cathode for direct heatsink grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input terminal for first rectifier leg | Accepts AC or pulsed input; connects to transformer secondary or switch node in flyback topology. |
| Pin 2 (Cathode) | Common output node for both legs | Electrically bonded to metal tab; must be thermally and electrically connected to heatsink/ground plane. |
| Pin 3 (Anode 2) | Input terminal for second rectifier leg | Enables dual-input/single-output configuration; used for dual-winding rectification or redundancy. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Provides ESD and transient voltage immunity up to ±30kV HBM without external clamping. |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock. |
| Lead-free & Green compliant | Meets RoHS 2 (2011/65/EU) and halogen/antimony-free requirements (<900ppm Br/Cl, <1000ppm Sb). |
| Low RθJC (2°C/W) | Enables 10W continuous power dissipation with ≤20°C ΔT over heatsink, reducing need for oversized thermal management. |
| TO-220AB mechanical standardization | Compatible with legacy PCB footprints and automated insertion equipment across industrial power designs. |
Applications
| DC Power Supply Output Rectification | Polarity Protection Circuit |
|---|---|
Use Scenario: Secondary-side rectification in 24V/48V offline SMPS for telecom and industrial control systems. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier converting transformer AC output to regulated DC; common-cathode configuration simplifies output filtering. Use Value: 0.84V VF reduces conduction loss by ~35% vs. silicon diodes, improving full-load efficiency from 88% to 92.5%. | Use Scenario: Reverse-voltage protection on 12V/24V input rails of embedded controllers and sensor modules. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-load; blocks reverse current during battery swap or hot-plug events. Use Value: 0.05mA IR at 100V ensures <1.2μW standby power loss, critical for battery-backed IoT nodes. |
| Motor Drive Flyback Clamp | Redundant Power Input OR-ing |
Use Scenario: Freewheeling path for brushed DC motor current during PWM turn-off in automotive seat/mirror actuators. IC Role / Device Role / Timing Role: Recirculating diode across motor winding; dual-leg layout accommodates split-winding or dual-motor configurations. Use Value: 150A IFSM withstands 5× stall current surges without degradation, extending system MTBF. | Use Scenario: OR-ing two independent 24V power sources (e.g., main supply + backup battery) in rail-switching UPS modules. IC Role / Device Role / Timing Role: Each anode handles one source; common cathode delivers combined output, eliminating cross-conduction risk. Use Value: Matched VF between legs ensures balanced current sharing within ±5%, avoiding thermal runaway. |
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-20CPH06-M3 | 60V VRRM, 20A total (10A/leg), VF = 0.62V @ 10A, RθJC = 2.5°C/W | Limited to ≤60V systems; lower VF improves light-load efficiency but sacrifices bus voltage headroom. | Select when 60V rating suffices and lowest possible conduction loss is prioritized over voltage margin. |
| ON Semiconductor MBR20100CTG | Identical 100V/10A/leg specs, same TO-220AB package, AEC-Q101 qualified, VF = 0.85V @ 10A | No functional difference; minor process variation yields 0.01V higher VF and different date-code marking. | Drop-in replacement with identical thermal, electrical, and mechanical behavior; suitable for BOM flexibility. |
Compared with VS-20CPH06-M3, MBR20100CT-LJ provides 40V higher blocking margin for 48V+ systems; versus MBR20100CTG, it offers identical performance with Diodes Inc.-specific traceability and packaging-both alternatives maintain TO-220AB footprint compatibility.

FAQ
Is MBR20100CT-LJ pin-compatible with MBRF20100CT?
Yes, MBR20100CT-LJ (TO-220AB) and MBRF20100CT (ITO-220AB) share identical pinout: Anode 1, Common Cathode, Anode 2. However, ITO-220AB has insulated tab, while TO-220AB tab is electrically connected to cathode-thermal mounting and isolation requirements differ.
What is the maximum allowable case temperature for continuous operation?
The device supports continuous operation up to TC = +100°C per datasheet derating curve. At TC = 100°C, IO per leg is rated at 10A; exceeding this requires thermal redesign or derating to prevent junction overheating beyond +175°C absolute maximum.
Does the "-LJ" suffix indicate lead-free or halogen-free compliance?
Yes, the "-LJ" suffix denotes Diodes Incorporated's standard lead-free, halogen-free, and antimony-free "Green" construction, fully compliant with RoHS 2 (2011/65/EU) and meeting <900ppm Br/Cl and <1000ppm Sb thresholds per internal specification AP02002.
Can MBR20100CT-LJ be used in parallel for higher current?
No-parallel operation is not recommended due to VF mismatch between legs and units, which causes current imbalance and thermal runaway. For >20A total, use a single higher-rated device (e.g., MBR30100CT) or separate discrete Schottky diodes with matched VF binning and individual thermal paths.
