Product details
Overview
MBR20150CTF-G1 from Diodes Incorporated is a high-voltage dual Schottky rectifier in TO-220F-3 package, rated for 150 V reverse voltage, 10 A per diode leg (20 A total), and 0.9 V max forward voltage at 10 A and +25°C. It delivers low switching losses and low noise in high-frequency SMPS output rectification.
For engineers reviewing the MBR20150CTF-G1 datasheet, MBR20150CTF-G1 pinout, MBR20150CTF-G1 application, or MBR20150CTF-G1 equivalent, key selection criteria include thermal resistance (RθJC = 3.0°C/W), junction temperature rating (+150°C), RoHS-compliant green packaging, and dual-anode common-cathode configuration for synchronous rectifier topologies.
Technical Context
This dual Schottky rectifier integrates two independent 150 V / 10 A diode legs in a single TO-220F-3 thermally enhanced package with isolated mounting tab. Its guard-ring structure enhances ruggedness against transient stress and improves reliability under repetitive surge conditions.
The device operates up to +150°C junction temperature and exhibits low IR of 0.05 mA at 25°C and 20 mA at 125°C, enabling stable performance in compact, high-density power converters where thermal management is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage per diode leg; defines safe blocking capability in DC-DC and AC-DC secondary-side applications. |
| IF(AV) per leg | 10 A - Average forward current rating per diode at TC = +134°C; supports continuous 20 A dual-leg output in well-heatsinked designs. |
| VF (max) | 0.9 V @ 10 A, +25°C - Low conduction loss enables >92% efficiency in 12 V/24 V output rails with minimal thermal rise. |
| RθJC | 3.0 °C/W - Junction-to-case thermal resistance for TO-220F-3 package; allows direct heatsink mounting without insulating pads for improved thermal transfer. |
| TJ(max) | +150°C - Maximum operating junction temperature; permits use in industrial environments with ambient up to +85°C and moderate airflow. |
| IR (max) | 0.05 mA @ 25°C - Ultra-low reverse leakage ensures minimal standby power loss in offline adapters and PoE injectors. |
Pinout & Package
MBR20150CTF-G1 uses the TO-220F-3 package: insulated plastic case with metal tab (non-conductive mounting surface), 3-terminal layout, and matte tin–annealed copper leadframe. Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2 - verified from Diodes Inc. DS37333 Rev. 3-2 Figure "Pin Assignments (Front View)".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 | Input terminal for first Schottky diode leg; connects to transformer secondary or switch node in center-tapped or dual-output configurations. |
| 2 | Cathode (Common) | Shared cathode output node; serves as positive DC output rail connection point for both diode legs. |
| 3 | Anode 2 | Input terminal for second Schottky diode leg; enables dual-channel rectification without external parallel diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.75 V @ 10 A, +125°C - reduces conduction loss by ~25% vs. standard silicon rectifiers at elevated temperatures. |
| Guard-ring protection | Integrated edge termination - suppresses premature avalanche breakdown during voltage transients in flyback snubber circuits. |
| Green package compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - meets IPC-1752A Tier 2 reporting requirements. |
| ESD robustness | 8 kV HBM - eliminates need for external ESD protection during board assembly and handling in automated SMT lines. |
Applications
| Server Power Supply Rectification | Industrial DC-DC Converter Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR20150CTF-E1 | Same die, identical electrical specs; RoHS-compliant finish but not halogen-free. | No green material compliance; unsuitable for strict environmental programs requiring halogen-free certification. | Select when RoHS-only compliance suffices and cost sensitivity outweighs green packaging mandates. |
| MBR20150CT-LJ | Updated version with lower RθJC (1.8°C/W), VF reduced to 0.85 V @ 10 A, and enhanced surge rating (IFS M = 150 A). | Requires updated thermal pad layout; superior for new designs targeting higher power density and extended lifetime. | Preferred for new designs per Diodes Inc. Note 6; offers measurable thermal and efficiency gains over G1 variant. |
Compared with MBR20150CTF-G1, the E1 variant trades green compliance for cost, while the LJ variant delivers measurable thermal and conduction-loss improvements-making it the recommended upgrade path for next-generation power supplies.

FAQ
Is MBR20150CTF-G1 pin-compatible with TO-220-3 variants like MBR20150CT-G1?
Yes - both share identical 3-pin front-view layout (A1-K-A2), but the TO-220F-3 package has an insulated mounting tab, whereas TO-220-3 requires electrical isolation hardware when mounted to grounded heatsinks. Mechanical fit is identical, but thermal and safety design rules differ.
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF(AV) = 10 A per leg at TC = +134°C. Exceeding this case temperature risks derating below rated current; sustained operation above +134°C requires verification via thermal simulation using RθJC = 3.0°C/W and actual heatsink thermal resistance.
Does MBR20150CTF-G1 support paralleling for higher current?
No - it is a monolithic dual-diode device with shared thermal path; paralleling multiple units does not scale current linearly due to thermal coupling and forward voltage mismatch. For >20 A, select higher-rated single-die alternatives or multi-chip modules.
Can MBR20150CTF-G1 replace standard silicon rectifiers in existing designs?
Yes - its 150 V VRRM and 0.9 V VF allow drop-in replacement in many 100–120 V RMS secondary-side applications, provided layout accommodates lower reverse recovery noise and revised thermal management due to higher thermal conductivity.
