Product details
Overview
MBR10100CT-LJ from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 100V peak reverse voltage, with max 0.84V forward voltage at 5A/25°C and 0.05mA reverse leakage at 100V/25°C; used for polarity protection and freewheeling in DC power supplies and motor drives.
For engineers reviewing the MBR10100CT-LJ datasheet, MBR10100CT-LJ pinout, MBR10100CT-LJ application, or MBR10100CT-LJ equivalent, key selection criteria include per-leg 5A average current rating, thermal resistance of 4°C/W (junction-to-case), AEC-Q101 qualification, RoHS/Green compliance, and TO-220AB mechanical compatibility with standard heatsinks.
Technical Context
This dual-diode Schottky rectifier integrates two independent 5A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional freewheeling paths. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction loss in high-efficiency 12–48V DC systems.
Designed for commercial-grade reliability, it operates from –55°C to +175°C junction temperature, supports 110A non-repetitive surge current (8.3ms half-sine), and requires heatsinking due to RθJA = 16°C/W in TO-220AB configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 48V bus clamp or flyback snubber circuits. |
| IO (per leg) | 5 A - Continuous average forward current per diode leg; determines usable output capacity in dual-rail power converters. |
| VF (max) | 0.84 V @ 5A, 25°C - Forward voltage drop limiting conduction loss; enables <4.2W dissipation per leg at full load. |
| IR (max) | 0.05 mA @ 100V, 25°C - Reverse leakage current; ensures minimal standby power loss in battery-backed systems. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance; mandates use of external heatsink for sustained >3A operation. |
| IFSM | 110 A - Non-repetitive surge rating; withstands motor startup or capacitor inrush transients without failure. |
| AEC-Q101 | Qualified - Meets automotive-grade reliability standards for temperature cycling, HTRB, and ESD; suitable for industrial transport electronics. |
Pinout & Package
Package: TO-220AB, molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 rated, 1.95g weight. Mounting tab is cathode-connected and electrically active.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky diode leg; connects to switched high-side node in buck converter or inductive load. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode node for both diodes; must be connected to system ground or low-side return path and thermally coupled to heatsink. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky diode leg; enables dual-path rectification or redundant freewheeling in H-bridge drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient robustness without external TVS, reducing BOM count in noisy industrial environments. |
| Low VF (0.72–0.84 V) | Reduces forward power loss by ≥30% vs. silicon PN rectifiers at 5A, directly improving efficiency in 12V/24V SMPS designs. |
| AEC-Q101 qualification | Validates long-term reliability under thermal shock, humidity, and bias stress-critical for transportation and telecom infrastructure. |
| Halogen- and antimony-free "Green" compound | Meets IEC 61249-2-21 requirements (<900 ppm Br/Cl, <1000 ppm Sb); supports eco-compliance in EU and Asia-Pacific markets. |
Applications
| DC Power Supply Input Stage | Motor Drive Freewheeling |
|---|---|
Use Scenario: AC/DC front-end rectification in 48V telecom power supplies with dual-output rails. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier providing isolated positive rail generation and reverse-polarity protection. Use Value: 0.84V VF limits heat generation at 5A per rail, enabling compact heatsink design and >92% conversion efficiency. | Use Scenario: Bidirectional energy recirculation in brushed DC motor H-bridge drivers. IC Role / Device Role / Timing Role: Common-cathode dual Schottky enabling simultaneous freewheeling during PWM off-time across both motor terminals. Use Value: 110A IFSM handles peak back-EMF surges; low IR prevents battery drain during idle states. |
| Industrial PLC Power Management | LED Driver Polarity Protection |
Use Scenario: Input protection and hold-up rectification in programmable logic controller (PLC) 24V DC power modules. IC Role / Device Role / Timing Role: Polarity protection diode and bulk rectifier in redundant 24V input stage with hot-swap capability. Use Value: AEC-Q101 qualification ensures stable operation across –40°C to +70°C ambient; RθJC = 4°C/W enables direct PCB-mount heatsinking. | Use Scenario: Reverse-voltage safeguard in constant-current LED driver outputs driving multi-string arrays. IC Role / Device Role / Timing Role: Series-connected Schottky anode-leg protecting downstream LED strings from accidental reverse connection. Use Value: 0.05mA IR at 100V prevents measurable dark-current leakage, preserving LED dimming linearity and longevity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | Same 100V VRRM, 5A IO/leg, but TO-220AC package (single cathode tab); VF = 0.78V typ @ 5A. | Lacks common-cathode dual configuration; requires separate cathode routing for dual-leg use. | Select when discrete anode control is preferred or board layout favors single-tab mounting. |
| VBSE10100C-M3/4W | 100V, 5A/leg, VF = 0.82V max @ 5A, but ITO-220AB package; RθJC = 6°C/W. | Higher thermal resistance reduces power handling without forced airflow; same pinout but thinner profile. | Choose for space-constrained designs where height clearance is limited and lower surge margin is acceptable. |
Compared with STPS10H100CG and VBSE10100C-M3/4W, MBR10100CT-LJ offers integrated common-cathode topology and lowest RθJC (4°C/W), making it optimal for thermally demanding dual-path rectification where shared return and heatsink coupling are critical.

FAQ
What is the maximum junction temperature for MBR10100CT-LJ?
The absolute maximum junction temperature is +175°C, with continuous operation supported from –55°C to +175°C. Derating begins above +25°C ambient per Figure 4 in DS36378; at 70°C ambient, maximum average forward current drops to ~3.5A per leg with standard heatsinking.
Is MBR10100CT-LJ pin-compatible with MBRF10100CT-JT?
Yes-both share identical TO-220AB pinout (Anode1–Cathode–Anode2) and mechanical footprint. The MBRF10100CT-JT uses ITO-220AB, a thinner variant with different thermal resistance (RθJC = 6°C/W), but same terminal assignment and marking orientation.
Does MBR10100CT-LJ require a heatsink in all applications?
Yes-due to RθJA = 16°C/W in TO-220AB, sustained operation above ~1.5A per leg without heatsinking exceeds safe junction temperature. At 5A/leg, a minimum 4°C/W heatsink is required to maintain TJ ≤ 125°C at 50°C ambient, per thermal calculations in DS36378 Note 5.
How does the guard ring construction improve real-world reliability?
The integrated guard ring mitigates edge breakdown during voltage transients, raising the effective ESD withstand level to >8kV HBM and improving immunity to fast-rising noise in motor drive and industrial switching environments-verified per AEC-Q101 stress test protocols.
