Product details
Overview
MBR30100CT-LJ from Diodes Incorporated is a 30A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 100V peak reverse voltage, 0.84V max forward voltage at 15A/25°C, and 190A non-repetitive surge current - used as polarity protection and freewheeling diode in DC-DC converter outputs and industrial power supplies.
For engineers reviewing the MBR30100CT-LJ datasheet, MBR30100CT-LJ pinout, MBR30100CT-LJ application, or MBR30100CT-LJ equivalent, key selection criteria include per-leg forward voltage drop, thermal resistance (2°C/W junction-to-case), RoHS-compliant matte tin terminals, AEC-Q101 qualification, and TO-220AB mechanical compatibility with standard heat sinks.
Technical Context
This dual-diode configuration shares a common cathode terminal, enabling independent anode routing for two parallel rectification paths. Each leg operates with guard ring die construction to suppress edge leakage and sustain 100V blocking capability under transient conditions.
Thermal performance is defined by low RθJC (2°C/W) when mounted on a 45mm × 20mm × 12mm heatsink, supporting continuous 15A per leg at +25°C ambient - derated to ~7.5A per leg at +100°C ambient per Figure 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each leg withstands without breakdown |
| IO (per leg) | 15 A - Continuous average forward current per diode leg at +25°C ambient with heatsink |
| VF (max) | 0.84 V @ 15A, +25°C - Directly impacts conduction loss and thermal load in high-current DC paths |
| IFSM | 190 A - Peak non-repetitive surge current tolerance for 8.3ms half-sine, critical for inrush handling |
| RθJC | 2 °C/W - Junction-to-case thermal resistance enables efficient heat transfer to external heatsink |
| IR (max) | 0.05 mA @ 100V, +25°C - Low leakage preserves efficiency in standby and light-load operation |
| TJ range | −55 to +175 °C - Extended temperature rating supports under-hood and industrial environments |
Pinout & Package
TO-220AB package with three leads: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Molded plastic case meets UL 94V-0 flammability rating; matte tin-plated copper leadframe ensures solderability per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Leg 1 | Input node for first rectification path; connects to unidirectional AC or switching node |
| Pin 2 | Common Cathode | Shared output node for both legs; routed to system ground or low-side return path |
| Pin 3 | Anode of Leg 2 | Input node for second independent rectification path; enables dual-output or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses surface leakage and improves voltage stability at high temperature and humidity |

| Lead-free & halogen-free | Meets RoHS 2 (2011/65/EU) and "Green" definition: <900ppm Br, <900ppm Cl, <1000ppm Sb |
| Low RθJC (2°C/W) | Enables compact thermal design with minimal heatsink mass for 30A total output applications |
| High IFSM (190A) | Withstands repeated inrush events in motor drives and SMPS startup without degradation |
Applications
| DC-DC Converter Output Stage | Industrial Motor Drive Freewheeling |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 12V–48V isolated DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing low-loss, fast-recovery output rectification with shared cathode return. Use Value: 0.84V VF reduces conduction loss by ~35% vs. silicon diodes, lowering thermal stress and improving efficiency above 90%. | Use Scenario: Bidirectional flyback path in H-bridge motor controllers driving 24V/30A brushed DC motors. IC Role / Device Role / Timing Role: Freewheeling diode pair clamping inductive kickback during PWM turn-off across both motor phases. Use Value: 190A IFSM handles peak back-EMF surges without avalanche failure; TO-220AB mounting simplifies heatsinking on PCB. |
| Automotive Polarity Protection | LED Driver Power Input Stage |
Use Scenario: Reverse-voltage protection at battery input of ADAS camera modules and infotainment head units. IC Role / Device Role / Timing Role: Common-cathode dual diode configured as OR-ing device to block reverse current while passing forward supply. Use Value: AEC-Q101 qualification ensures operation over −40°C to +125°C junction; 100V VRRM covers load-dump transients. | Use Scenario: Input rectification stage in constant-current LED drivers for street lighting and signage. IC Role / Device Role / Timing Role: High-current AC-to-DC conversion feeding buck controller ICs; dual-leg layout supports split-input filtering. Use Value: 15A per-leg rating supports >40W LED strings; low IR (<0.05mA) prevents standby power drain in always-on systems. |
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-30CPH01-M3 | Same TO-220AB package, 100V VRRM, but 0.82V VF @ 15A - marginally lower conduction loss | Not AEC-Q101 qualified; lacks automotive reliability validation | Select for cost-sensitive industrial use where automotive qualification is unnecessary |
| ON Semiconductor MBR30H100CTG | Identical electrical specs and TO-220AB package; same 0.84V VF, 190A IFSM, and −55°C to +175°C rating | RoHS-compliant but not explicitly halogen-free per Diodes' "Green" definition | Drop-in replacement where halogen-free compliance is not mandated by end-customer spec |
Compared with VS-30CPH01-M3 and MBR30H100CTG, MBR30100CT-LJ uniquely combines AEC-Q101 qualification, halogen/antimony-free "Green" status, and documented 2°C/W RθJC - making it preferred for automotive and regulated industrial deployments requiring full material and reliability traceability.

FAQ
What is the maximum junction temperature for MBR30100CT-LJ?
The absolute maximum junction temperature is +175°C, with continuous operation supported from −55°C to +175°C. Derating begins at +25°C ambient per Figure 4: at +100°C ambient, maximum IO drops to approximately 7.5A per leg with proper heatsinking.
Is MBR30100CT-LJ suitable for surface-mount assembly?
No - MBR30100CT-LJ uses a through-hole TO-220AB package with bent leads designed for wave or hand soldering into plated-through holes. It is not compatible with reflow SMT processes due to leadform geometry and thermal mass.
How does the common-cathode configuration affect circuit layout?
The shared cathode (Pin 2) simplifies grounding by allowing both anodes (Pins 1 and 3) to connect to separate switching nodes while returning to one low-impedance point - reducing ground loop area and easing thermal pad routing on the PCB.
Does MBR30100CT-LJ require a heatsink in all applications?
Yes - at rated 15A per leg, junction temperature rise exceeds safe limits without heatsinking. With RθJC = 2°C/W and RθJA = 15°C/W, a heatsink is mandatory for continuous operation above ~2A per leg at +25°C ambient.
