Product details
Overview
MBRF20150CT-LJ from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in ITO-220AB package, rated for 150V peak reverse voltage, 0.90V max forward voltage at 10A/25°C, and 0.05mA max leakage at 150V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBRF20150CT-LJ datasheet, MBRF20150CT-LJ pinout, MBRF20150CT-LJ application, or MBRF20150CT-LJ equivalent, key selection criteria include per-leg forward current rating (10A), thermal resistance (5°C/W junction-to-case), surge capability (170A IFSM), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-diode Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional clamping. Its guard ring die construction enhances transient immunity, while low VF minimizes conduction loss in high-frequency switching converters.
Designed for surface-mount-compatible through-hole mounting on heatsinks, it operates across –55°C to +175°C with RθJC = 5°C/W (ITO-220AB) and supports 170A non-repetitive surge current under 8.3ms half-sine conditions - critical for inductive load flyback energy handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per leg; defines safe DC bus voltage margin in 12–48V systems. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg at TA = 25°C with heatsink; total device output = 20A shared cathode. |
| VF (max) | 0.90 V @ 10A, 25°C - Low conduction loss enables >92% efficiency in 12V/10A SMPS outputs. |
| IR (max) | 0.05 mA @ 150V, 25°C - Minimal leakage preserves battery hold-up time in always-on circuits. |
| IFSM | 170 A - Withstands motor startup surges and capacitor inrush without degradation. |
| RθJC | 5 °C/W - Enables compact heatsink design: ~10W dissipation requires only 50°C ΔT rise from case to junction. |
| AEC-Q101 | Qualified - Validated for automotive under-hood applications including engine control modules and body electronics. |
Pinout & Package
Package: ITO-220AB (TO-220F-3), thermally enhanced plastic case with isolated tab, RoHS-compliant matte tin-plated copper leadframe, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode leg | Accepts input from positive rail or inductive source; electrically isolated from tab. |
| Pin 2 (Cathode) | Common cathode node | Shared output node for both legs; connected to heatsink tab (electrically active). |
| Pin 3 (Anode B) | Anode of second diode leg | Independent anode path for dual-channel operation or redundancy; no internal connection to Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient robustness without external TVS, meeting ISO 7637-2 pulse 5a requirements. |
| Low VF (0.90V max @ 10A) | Reduces power loss by ≥35% vs. standard silicon rectifiers, lowering thermal stress in enclosed enclosures. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, and mechanical shock - suitable for under-dash ECUs. |
| Halogen & antimony free | Meets JEDEC JS709B "Green" definition (<900ppm Br/Cl, <1000ppm Sb); supports end-of-life recycling compliance. |
| Moisture sensitivity Level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines despite through-hole form factor. |
Applications
| DC Power Supply Input Stage | Automotive Body Control Module |
|---|---|
Use Scenario: Full-wave rectification of 24VAC transformer output feeding regulated 12V DC bus. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replaces discrete bridge; common cathode simplifies PCB layout and reduces trace inductance.

Use Value: 0.05mA IR at 150V prevents standby current drain in always-on server management controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20H150CG | Same 150V/20A rating, but TO-220AC package (non-isolated tab); RθJC = 3.5°C/W. | Lacks isolation between tab and cathode - requires insulating washer in heatsink mounting. | Preferred where higher thermal performance is critical and isolation is managed externally. |
| Vishay V20150CI | Identical ITO-220AB package and pinout; VF = 0.88V typ @ 10A, IR = 0.03mA max. | Slightly lower leakage improves battery backup retention; same AEC-Q101 qualification. | Drop-in replacement with marginal conduction/leakage improvement; verify date-code availability. |
Compared with STPS20H150CG and V20150CI, MBRF20150CT-LJ offers integrated electrical isolation via ITO-220AB's insulated tab - eliminating insulator hardware and reducing assembly cost in automotive and industrial designs requiring cathode-to-heatsink isolation.

FAQ
What is the maximum junction temperature for continuous operation?
The MBRF20150CT-LJ has a rated operating junction temperature range of –55°C to +175°C. For continuous operation at full 10A per leg, thermal design must ensure TJ does not exceed 175°C - typically achieved with a heatsink maintaining case temperature ≤125°C given its 5°C/W RθJC.
Is the heatsink tab electrically isolated from the cathode terminal?
Yes - the ITO-220AB package features an electrically isolated tab that is internally connected to the common cathode (Pin 2). This allows direct mounting to grounded metal chassis without shorting the output rail, unlike standard TO-220AB variants.
How does the guard ring structure improve reliability?
The guard ring die construction surrounds the active junction to suppress edge breakdown during voltage transients. It increases the device's immunity to ESD events and load-dump pulses (e.g., ISO 7637-2), extending service life in automotive environments without requiring external protection components.
Can MBRF20150CT-LJ replace MBR20150CT-LJ in existing designs?
Yes - both share identical electrical specs and pinout, but MBRF20150CT-LJ uses the ITO-220AB (TO-220F-3) package with insulated tab, whereas MBR20150CT-LJ uses standard TO-220AB. Replacement requires verifying heatsink isolation requirements; no PCB layout change is needed.
