Product details
Overview
MBR2050CT-Y from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-220AB package, rated for 50V repetitive peak reverse voltage (VRRM), with 0.80V typical forward voltage at 10A/25°C and 150A surge capability - used in high-efficiency DC-DC converters and switching power supplies.
For engineers reviewing the MBR2050CT-Y datasheet, MBR2050CT-Y pinout, MBR2050CT-Y application, or MBR2050CT-Y equivalent, key selection criteria include VRRM=50V, IF=20A, VF≤0.95V @20A/25°C, RθJC=1°C/W, and TO-220AB thermal performance in compact high-current rectification.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode configuration, enabling dual-channel synchronous rectification or full-wave bridge input stages. Its low VF and fast recovery support high-frequency SMPS operation up to 200 kHz without significant conduction loss.
The junction-to-case thermal resistance of 1°C/W allows direct heatsink mounting for sustained 20A operation at TJ ≤150°C, while guard ring protection ensures robustness against transient overvoltage events in industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum reverse blocking voltage per diode; defines safe operating range in 48V-input DC-DC or offline auxiliary supplies. |
| IF | 20 A - Continuous average forward current per diode; supports high-power adapter outputs without parallel devices. |
| VF @10A/25°C | 0.80 V - Low conduction loss enables >92% efficiency in 12V-output buck converters at full load. |
| IFSM | 150 A - Single half-sine surge rating permits reliable cold-start into capacitive loads or short-circuit transients. |
| RθJC | 1 °C/W - Enables 100W+ dissipation with standard TO-220 heatsink; critical for thermally constrained PCB layouts. |
| IR @50V/25°C | 100 µA - Low leakage preserves standby power in energy-sensitive applications like IoT power managers. |
| TJ max | 150 °C - Allows operation in sealed enclosures or high-ambient environments without derating below 20A. |
Pinout & Package
Package: TO-220AB, 3-terminal molded plastic case with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 rated compound, 1.88g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky diode; electrically isolated from tab and Pin 2. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode node connected to metal tab; requires insulated mounting if tab is grounded. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky diode; fully independent of Anode 1 except shared cathode path. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF ≤0.95V @20A/25°C reduces conduction loss by ≥35% vs. comparable silicon rectifiers. |
| Guard ring overvoltage protection | Enables stable operation under 10,000 V/μs dv/dt transients without snapback or latch-up. |
| Dual-die common-cathode configuration | Supports full-wave rectification or dual-output synchronous rectification with single-package footprint. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and JESD201 Class 1A whisker requirements for automotive and industrial assembly. |

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-MBR2050CT | VRRM=50V, IF=20A, VF=0.82V@10A/25°C, RθJC=1.1°C/W, same TO-220AB package but non-halogen-free molding compound. | Approved for legacy industrial designs where halogen-free compliance is not mandated; slightly higher thermal resistance limits peak power density. | Select when cost sensitivity outweighs RoHS/halogen-free requirements and thermal margin ≥5°C is available. |
| ON Semiconductor MBR2050CT | VRRM=50V, IF=20A, VF=0.85V@10A/25°C, RθJC=1.2°C/W, TO-220AB with lead-free plating but no JESD201 whisker certification. | Suitable for consumer-grade adapters; lacks whisker test validation for long-life automotive or medical deployments. | Prefer for high-volume consumer power supplies where 10-year field reliability is not contractually required. |
Compared with Vishay VS-MBR2050CT and ON Semi MBR2050CT, the MBR2050CT-Y offers tighter VF tolerance, lower RθJC, and full halogen-free + whisker-tested construction - making it optimal for medical, telecom, and industrial applications demanding long-term thermal stability and regulatory compliance.

FAQ
What is the maximum junction temperature rating for MBR2050CT-Y?
The MBR2050CT-Y has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet Version B2104. This rating allows continuous 20A operation with appropriate heatsinking and ensures reliability in enclosed industrial enclosures where ambient temperatures reach 85°C. Derating curves confirm usable current remains above 15A at TJ = 125°C.
Is MBR2050CT-Y pin-compatible with other parts in the MBR20xCT-Y family?
Yes - all MBR20xCT-Y variants (e.g., MBR2035CT-Y through MBR20200CT-Y) share identical TO-220AB mechanical dimensions, pinout (Anode1–Cathode–Anode2), and mounting torque specification (0.56 N·m max). The MBR2050CT-Y can be substituted within the same footprint for voltage upgrades or downgrades, provided VRRM and VF requirements align with system design margins.
Does MBR2050CT-Y have a common-cathode or common-anode configuration?
The MBR2050CT-Y uses a common-cathode configuration: Pin 2 (center) and the metal tab are internally connected to the shared cathode node, while Pins 1 and 3 serve as independent anodes. This structure is confirmed in the marking diagram and thermal performance section of the Taiwan Semiconductor datasheet, enabling full-wave rectification or dual-output synchronous rectifier topologies.
What is the reverse leakage current specification for MBR2050CT-Y at 50V and 125°C?
Per the Electrical Specifications table in the Taiwan Semiconductor datasheet, the MBR2050CT-Y exhibits a maximum reverse leakage current (IR) of 10 mA at rated VR = 50V and junction temperature TJ = 125°C. This value is measured under pulse conditions (PW = 30 ms) and reflects stable performance under elevated thermal stress in high-ambient applications such as base station power modules.
How does the guard ring feature in MBR2050CT-Y improve system reliability?
The guard ring in MBR2050CT-Y provides edge termination that suppresses premature avalanche breakdown under fast dv/dt transients. With a rated critical rate of rise of off-state voltage (dv/dt) of 10,000 V/μs, this feature prevents localized hot-spot formation during switching noise events in high-frequency SMPS - directly improving long-term failure rate (FIT) in 24/7 industrial power systems using the MBR2050CT-Y.
