Product details
Overview
MBR20150CT-LJ from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 150V peak reverse voltage, with max 0.90V forward voltage at 10A/25°C and 0.05mA 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 MBR20150CT-LJ datasheet, MBR20150CT-LJ pinout, MBR20150CT-LJ application, or MBR20150CT-LJ equivalent, key selection criteria include per-leg 10A average current rating, thermal resistance of 3°C/W (junction-to-case), AEC-Q101 qualification, RoHS-compliant matte tin finish, and TO-220AB mechanical compatibility with standard heatsinks.
Technical Context
This dual-diode Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional clamp configurations. 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 across –55°C to +175°C junction temperature range and supports surge currents up to 170A (8.3ms half-sine). Thermal performance is optimized for mounting on standard 45mm × 20mm × 12mm heatsinks per Diodes' recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks up to 150V reverse bias without breakdown in continuous operation |
| IO (per leg) | 10 A - delivers 10A average forward current per diode leg under 60Hz resistive load |
| VF (max) | 0.90 V @ 10A, 25°C - ensures ≤0.9V conduction drop, reducing power loss to ≤9W per leg at full load |
| IR (max) | 0.05 mA @ 150V, 25°C - limits reverse leakage to sub-50µA, critical for low-power standby modes |
| RθJC | 3 °C/W - enables efficient heat transfer from junction to case when mounted on heatsink |
| IFSM | 170 A - withstands short-duration inrush surges typical in motor startup or capacitor charging |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
TO-220AB package with 3-terminal configuration: Pin 1 (Anode 1), Pin 2 (Cathode, common), Pin 3 (Anode 2). Molded plastic case meets UL 94V-0 flammability rating; terminals feature matte tin annealed over copper leadframe for MIL-STD-202 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Leg 1 | Input terminal for first Schottky diode; connects to input rail or switching node |
| Pin 2 | Common Cathode | Shared output node for both diodes; ties to system ground or return path |
| Pin 3 | Anode of Leg 2 | Input terminal for second Schottky diode; enables dual-path or complementary rectification |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and transient robustness without external TVS, supporting IEC 61000-4-2 level 4 compliance |
| Low VF (0.90V max @ 10A) | Reduces conduction loss by ~30% vs. comparable silicon rectifiers, improving efficiency in 12V/24V SMPS |
| AEC-Q101 qualification | Validates suitability for automotive body electronics, including HVAC blower and lighting modules |
| Lead-free & halogen-free | Meets RoHS 2 and JEDEC JS709C green standards (<900ppm Br/Cl, <1000ppm Sb) |

Applications
| DC Power Supply Input Stage | Motor Drive Freewheeling |
|---|---|
Use Scenario: AC/DC front-end rectification in industrial 24V switch-mode power supplies with 10–15A output capability. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing low-loss, high-frequency half-wave rectification with shared cathode return. Use Value: 0.90V VF reduces conduction loss to 9W per leg, lowering heatsink requirements versus 1.1V silicon alternatives. | Use Scenario: Bidirectional flyback protection in brushed DC motor drivers with PWM-controlled H-bridge outputs. IC Role / Device Role / Timing Role: Common-cathode dual diode clamps inductive kickback from both motor terminals to ground during turn-off. Use Value: 170A IFSM rating handles repetitive motor stall surges without degradation; 3°C/W RθJC enables stable operation at 125°C ambient. |
| Polarity Protection Circuit | Redundant Power OR-ing |
Use Scenario: Reverse-voltage safeguard in field-replaceable modules powered via barrel jack or terminal block. IC Role / Device Role / Timing Role: Series-connected anode-leg diode blocking reverse current flow while passing forward current with minimal drop. Use Value: 0.05mA IR at 150V prevents battery drain in always-on systems; 150V VRRM supports 48V telecom and PoE++ applications. | Use Scenario: OR-ing diode pair in dual-input 12V power systems (e.g., battery + adapter) requiring seamless switchover. IC Role / Device Role / Timing Role: Two independent anode paths feeding common cathode output, enabling automatic source selection based on voltage priority. Use Value: Matched VF between legs ensures balanced current sharing; TO-220AB mounting allows direct heatsinking to chassis ground. |
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 | Same 150V VRRM, 10A/leg, but TO-247AC package; RθJC = 2.5°C/W; VF = 0.72V typ @ 10A | Better thermal performance and lower VF, but larger footprint and higher cost | Select for higher efficiency or elevated ambient (>85°C); verify PCB cutout and heatsink interface |
| ON Semiconductor MBR20150CTG | Identical specs and TO-220AB package; AEC-Q101 qualified; same VF/IR ratings; Pb-free matte tin finish | Direct form-fit-function replacement; identical marking and packaging (50/tube) | Preferred for supply chain diversification where Diodes' lead time is constrained |
Compared with VS-20CPH06-M3, MBR20150CT-LJ trades 0.18V higher VF for TO-220AB compatibility and lower cost; versus MBR20150CTG, it offers identical performance but different date-code marking and logistics traceability.

FAQ
What is the maximum junction temperature for MBR20150CT-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 the datasheet: at 80°C ambient, the per-leg average forward current must be reduced to approximately 6.5A for TO-220AB mounting on a standard heatsink.
Is MBR20150CT-LJ suitable for automotive applications?
Yes - it is AEC-Q101 qualified, confirming reliability for automotive body electronics such as HVAC actuators, seat controls, and LED lighting drivers. It meets stress test requirements including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing.
How does the common-cathode configuration affect circuit layout?
The shared cathode (Pin 2) simplifies grounding by allowing both anodes to connect to separate switching nodes while routing a single low-impedance return path to system ground. This reduces PCB trace inductance and improves EMI performance in high-dI/dt applications like motor drives.
Can MBR20150CT-LJ replace a single 20A Schottky in TO-220?
No - it contains two 10A legs, not one 20A device. Using only one leg delivers 10A; paralleling both anodes is unsafe due to mismatched VF causing current imbalance. For true 20A single-path rectification, select a monolithic 20A part like MBR30150CT or equivalent.
