Product details
Overview
MBR20150CT-G1 from Diodes Incorporated is a high-voltage dual common-cathode Schottky rectifier 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 operates up to +150°C junction temperature and is optimized for high-frequency switch-mode power supply output rectification with low switching losses and low noise.
For engineers reviewing the MBR20150CT-G1 datasheet, MBR20150CT-G1 pinout, MBR20150CT-G1 application, or MBR20150CT-G1 equivalent, key selection criteria include its dual common-cathode TO-220-3 configuration, thermal resistance of 2.0°C/W (junction-to-case), guard-ring stress protection, RoHS-compliant green packaging, and suitability for medium-voltage DC-DC and AC-DC power conversion stages.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220-3 package with shared cathode (Pin 2), enabling synchronous or interleaved rectification topologies. Its low VF and fast recovery eliminate minority-carrier storage delay, making it ideal for high-frequency operation above 100 kHz.
The internal guard-ring structure enhances ruggedness against transient overvoltage and localized thermal runaway. Thermal performance is defined by RθJC = 2.0°C/W (TO-220-3), requiring heatsinking for sustained 10 A per leg operation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage each diode withstands without breakdown |
| IF(AV) per leg | 10 A - Continuous average forward current per diode at TC = +134°C |
| VF max | 0.9 V @ 10 A, +25°C - Low conduction loss critical for efficiency in high-current SMPS outputs |
| IR max | 0.05 mA @ 150 V, +25°C - Minimal leakage preserves regulation in standby and light-load conditions |
| TJ max | +150°C - Enables operation in thermally constrained industrial and computing power supplies |
| RθJC | 2.0°C/W - Junction-to-case thermal resistance defines minimum heatsink requirement for thermal management |
| Package | TO-220-3 (2) - Through-hole, isolated tab, common-cathode pinout (A1–K–A2) |
Pinout & Package
MBR20150CT-G1 uses the TO-220-3 (2) package with isolated metal tab, molded plastic body, and matte tin–annealed copper leadframe. Pin 1: Anode 1 (A1), Pin 2: Common Cathode (K), Pin 3: Anode 2 (A2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode Leg 1 | Input terminal for first rectification path; connects to transformer secondary or switching node |
| 2 (K) | Common Cathode | Shared output node for both diodes; ties to output capacitor positive rail |
| 3 (A2) | Anode of Diode Leg 2 | Input terminal for second rectification path; enables dual-output or center-tapped configurations |
Key Features
| Feature | Design Value |
|---|---|
| Low Forward Voltage | 0.9 V max @ 10 A, +25°C - Reduces conduction loss by ~30% vs. comparable Si PN rectifiers |
| Guard-Ring Protection | Integrated edge termination - Improves surge robustness and prevents premature avalanche failure under voltage transients |
| +150°C Junction Rating | Rated operation up to TJ = +150°C - Supports compact designs with limited airflow or high ambient temperatures |
| Green Package Compliance | Halogen- and antimony-free, RoHS-compliant molding compound - Meets IEC 61249-2-21 and JEDEC J-STD-020 standards |
| High Surge Capacity | IFS M not specified but validated per JEDEC JESD22-A114 - Withstands typical AC line surges in offline PSUs without derating |
Applications
| Server Power Supply Rectification | Industrial DC-DC Converter Output |
|---|---|
Use Scenario: High-efficiency 48 V input, 12 V/20 A output stage in ATX or EPS12V server PSUs. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing two discrete diodes; common-cathode topology simplifies PCB layout and reduces parasitic inductance. Use Value: 0.9 V VF minimizes power loss (≤9 W total at full load), directly improving system efficiency from 92% to 93.5%. | Use Scenario: 24 V to 5 V/10 A isolated flyback converter in PLC power modules. IC Role / Device Role / Timing Role: Secondary-side synchronous rectification element operating at 200 kHz switching frequency. Use Value: Fast zero-recovery eliminates reverse recovery spikes, reducing EMI filter size by 40% and enabling smaller Y-capacitors. |
| Telecom Brick Rectification | Test Equipment Power Stage |
Use Scenario: 36–75 V DC input, 3.3 V/15 A output in half-brick DC-DC modules for 5G baseband units. IC Role / Device Role / Timing Role: Dual-anode, common-cathode configuration supports parallel rectification paths for current sharing. Use Value: 2.0°C/W RθJC allows direct mounting to module chassis, eliminating dedicated heatsinks and saving >120 mm² board area. | Use Scenario: Programmable bench power supply with adjustable 0–30 V, 0–10 A output using active rectification control. IC Role / Device Role / Timing Role: Primary rectifier in high-precision linear + switching hybrid topology with low-noise output requirements. Use Value: <0.05 mA IR at +25°C ensures stable no-load regulation and sub-10 ppm output drift during calibration sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR20150CT-LJ | Same VRRM, IF(AV), VF; improved RθJC = 1.8°C/W; enhanced green compliance (halogen-free, antimony-free) | Identical pinout and footprint; qualified for new designs per Diodes' recommendation | Select for new designs requiring extended lifecycle support and tighter thermal specs |
| STPS20H15CG | 150 V, 20 A total, VF = 0.87 V @ 10 A, +25°C; RθJC = 2.2°C/W; TO-220AC package (non-isolated tab) | Non-isolated tab requires insulating hardware; lower VF offers marginal efficiency gain at cost of thermal margin | Choose only if existing PCB layout accommodates non-isolated mounting and thermal design permits higher RθJA |
Compared with MBR20150CT-G1, the MBR20150CT-LJ offers better thermal performance and updated environmental compliance for long-term design viability, while STPS20H15CG trades tab isolation for slightly lower VF-making it viable only where mechanical redesign is acceptable and thermal headroom exists.

FAQ
Is MBR20150CT-G1 suitable for surface-mount assembly?
No. MBR20150CT-G1 uses the through-hole TO-220-3 (2) package with leads designed for wave or hand soldering. It lacks SMD-compatible terminations or thermal pad geometry. For SMT alternatives, consider Diodes' APD20150CTQ-G1 in TO-263AB package.
What is the maximum recommended case temperature for continuous 10 A per leg operation?
The datasheet specifies IF(AV) = 10 A per leg at TC = +134°C. To sustain this current continuously, the case must be maintained at or below +134°C via heatsinking. Exceeding this temperature requires derating per Figure 3 in DS37333 Rev. 3-2.
Does MBR20150CT-G1 have avalanche rating or energy absorption capability?
No. As a Schottky rectifier, MBR20150CT-G1 has no specified avalanche energy rating (EAS). Its guard-ring improves transient voltage tolerance, but it is not rated for repetitive unclamped inductive switching. External TVS or clamping circuits are required for such conditions.
Can MBR20150CT-G1 replace a single 20 A Schottky in a center-tapped transformer design?
Yes - when wired with A1 and A2 connected to opposite transformer ends and K to the output rail, it functions as a center-tapped full-wave rectifier. This configuration delivers identical current capability to a single 20 A device while halving per-diode forward drop and improving thermal distribution.
