Product details
Overview
MBRF30100CT-LJ from Diodes Incorporated is a dual common-cathode Schottky barrier rectifier in ITO-220AB package, rated for 100 V peak reverse voltage and 15 A average forward current per leg (30 A total), with max 0.84 V forward voltage at 15 A and +25°C, used as polarity protection and recirculating diode in DC power supplies and motor drive circuits.
For engineers reviewing the MBRF30100CT-LJ datasheet, MBRF30100CT-LJ pinout, MBRF30100CT-LJ application, or MBRF30100CT-LJ equivalent, key selection criteria include per-leg thermal resistance (5 °C/W junction-to-case), 190 A non-repetitive surge rating, RoHS-compliant matte tin terminals, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling synchronous rectification or dual-path DC output management. Its guard ring die construction suppresses edge leakage and improves surge robustness, while low VF minimizes conduction losses in high-efficiency 12–48 V systems.
Designed for surface-mount-compatible through-hole assembly, it operates across –55 °C to +175 °C junction temperature range and delivers <0.05 mA leakage at 100 V and +25°C. Thermal performance is specified for ITO-220AB mounting on a defined heat sink (45 mm × 20 mm × 12 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V reverse transient without breakdown |
| IO (per leg) | 15 A - supports continuous 15 A DC current per anode path |
| VF (max) | 0.84 V @ 15 A, +25°C - enables <1.3 W conduction loss per leg |
| IFSM | 190 A - withstands 8.3 ms half-sine surge, critical for inductive turn-off |
| RθJC | 5 °C/W - junction-to-case thermal resistance for ITO-220AB package |
| IR (max) | 0.05 mA @ 100 V, +25°C - ensures minimal standby power loss |
| TJ Range | –55 to +175 °C - qualified for under-hood automotive and industrial environments |

Applications
| DC Power Supply Output Stage | Automotive Engine Control Unit (ECU) |
|---|---|
Use Scenario: Dual-rail 12 V/5 V synchronous rectification in compact AC-DC adapters and telecom PSUs. IC Role / Device Role / Timing Role: Polarity protection and recirculating diode for buck converter outputs. Use Value: 0.84 V VF reduces conduction loss by ~30% vs. standard PN rectifiers, improving efficiency above 85% at full load. | Use Scenario: Reverse-polarity protection and inductive flyback clamping in 12 V ECU power inputs. IC Role / Device Role / Timing Role: Dual-anode Schottky clamp absorbing relay coil and solenoid energy spikes. Use Value: 190 A IFSM handles >10× typical ECU inrush, and –55 to +175 °C rating ensures operation across under-hood extremes. |
| Industrial Motor Drive Brake Circuit | LED Driver Constant-Current Loop |
Use Scenario: Regenerative braking path in 24 V brushed DC motor controllers. IC Role / Device Role / Timing Role: Recirculating diode returning back-EMF energy to supply bus during PWM off-time. Use Value: Low VF minimizes heat generation during high-duty-cycle braking, reducing need for forced cooling. | Use Scenario: Cathode-return path in multi-string constant-current LED drivers with shared return. IC Role / Device Role / Timing Role: Common-cathode dual diode providing isolated forward paths for parallel LED strings. Use Value: Matched VF between legs (<0.02 V typical spread) ensures balanced current sharing across strings without external balancing resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG | Same TO-220AB package, 30 A total, but single common-anode configuration; VF = 0.78 V @ 15 A | Requires PCB layout change due to reversed polarity; not drop-in for common-cathode designs | Select only if redesigning cathode routing and leveraging lower VF |
| VB30100C-G | ITO-220AB package, 100 V/30 A, VF = 0.85 V @ 15 A, no AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial/commercial use only | Prefer for cost-sensitive non-automotive applications where AEC-Q101 is not required |
Compared with STPS30H100CG and VB30100C-G, MBRF30100CT-LJ uniquely offers common-cathode topology with AEC-Q101 qualification and verified 5 °C/W RθJC in ITO-220AB-critical for thermally constrained automotive and high-reliability industrial deployments.

FAQ
What is the difference between MBRF30100CT-LJ and MBR30100CT-LJ?
MBRF30100CT-LJ uses the ITO-220AB (TO-220F-3) package with insulated tab, while MBR30100CT-LJ uses standard TO-220AB. The ITO version provides electrical isolation between the tab and cathode, enabling direct mounting to grounded heat sinks without insulating hardware-critical for high-voltage isolation compliance in industrial power supplies.
Can MBRF30100CT-LJ be used in place of a single 30 A Schottky diode?
No-it contains two 15 A diodes sharing one cathode, not a single 30 A device. Using it as a single-diode replacement risks overcurrent on one leg. It is intended for dual-path applications like dual-output supplies or H-bridge freewheeling, where per-leg current stays ≤15 A.
Is the 190 A IFSM rating applicable to both legs simultaneously?
No-the 190 A IFSM is specified per leg under single-half-sine-wave conditions. Simultaneous surge on both legs would exceed thermal limits; the device must be applied such that surge events are staggered or limited to one leg at a time per datasheet derating guidelines.
Does the "-LJ" suffix indicate lead-free and halogen-free compliance?
Yes-the "-LJ" suffix denotes Diodes Incorporated's standard "Green" variant: lead-free per RoHS Directive 2011/65/EU, and halogen- and antimony-free per internal specification (<900 ppm Br/Cl, <1000 ppm Sb), confirmed in DS30674 Rev. 5.
