Product details
Overview
MBR3080CT-Y from Taiwan Semiconductor is a 30A, 80V dual-die Schottky barrier rectifier in TO-220AB package, featuring 0.84V max forward voltage at 15A/25°C, 200A surge capability, and 1.0°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in high-frequency switching power supplies.
For engineers reviewing the MBR3080CT-Y datasheet, MBR3080CT-Y pinout, MBR3080CT-Y application, or MBR3080CT-Y equivalent, key selection criteria include VRRM=80V, IF=30A continuous, dual-common-cathode configuration, thermal performance under forced-air or heatsink mounting, and RoHS/halogen-free compliance for industrial power designs.
Technical Context
This device integrates two independent Schottky diodes in a single TO-220AB package with common cathode connection, enabling full-wave rectification or parallel current handling. Its low VF and high IFSM support high-efficiency operation in 50–500 kHz SMPS topologies while maintaining TJ ≤ 150°C under rated load.
The guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards. Thermal resistance of 1.0°C/W (junction-to-case) enables direct heatsink mounting without thermal interface material in many medium-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 80 V - Maximum repetitive reverse voltage; defines safe DC blocking capability in secondary-side rectification |
| IF | 30 A - Continuous forward current per diode; supports sustained 30A output in dual-diode parallel mode |
| VF (max) | 0.84 V @ 15A, 25°C - Low conduction loss improves efficiency in 12–48V output rails |
| IFSM | 200 A - Non-repetitive surge rating; withstands startup inrush and transient overloads |
| RθJC | 1.0 °C/W - Enables thermal design with standard TO-220 heatsinks; limits ΔT to 30°C at 30A |
| TJ max | 150 °C - Maximum junction temperature; allows operation in enclosed industrial enclosures up to 70°C ambient |
| IR (max) | 200 µA @ 80V, 25°C - Low leakage preserves efficiency in standby and light-load conditions |

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-30CTQ080PbF | VF = 0.72V @ 15A (lower), RθJC = 1.2°C/W (higher), same TO-220AB package | Better conduction efficiency but slightly higher thermal impedance; requires marginally larger heatsink | Preferred where ultra-low VF dominates thermal budget constraints |
| ON Semiconductor MBR30H80CT | VF = 0.88V @ 15A (higher), RθJC = 1.0°C/W, same 80V/30A rating and TO-220AB | Higher conduction loss increases output stage temperature rise by ~5°C at full load | Suitable when sourcing flexibility is prioritized over peak efficiency optimization |
Compared with VS-30CTQ080PbF and MBR30H80CT, the MBR3080CT-Y delivers optimal balance of low VF, proven thermal resistance, and robust surge capability-making it ideal for cost-sensitive industrial SMPS where 0.84V VF and 1.0°C/W RθJC jointly enable compact, reliable 30A rectification without thermal compromise.

FAQ
What is the maximum junction temperature rating for MBR3080CT-Y?
The MBR3080CT-Y has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision D2104. This rating permits operation in enclosed industrial environments up to 70°C ambient when mounted on a heatsink with appropriate thermal interface. Derating curves confirm usable current capacity down to 15A at 125°C case temperature, ensuring robustness across extended thermal cycles.
Is MBR3080CT-Y pin-compatible with other parts in the MBR30xCT-Y family?
Yes, all MBR30xCT-Y devices-including MBR3045CT-Y, MBR3060CT-Y, MBR3080CT-Y, MBR30100CT-Y, and MBR30150CT-Y-share identical TO-220AB mechanical outline, pin assignment, and dual-common-cathode terminal configuration. The only functional difference is VRRM, allowing drop-in replacement within the same voltage safety margin constraints without PCB layout changes.
What is the forward voltage specification for MBR3080CT-Y at full rated current?
At IF = 30A and TJ = 25°C, the MBR3080CT-Y exhibits a maximum forward voltage (VF) of 0.94V per diode, as specified in the Electrical Specifications table of the Taiwan Semiconductor datasheet. At elevated junction temperature (125°C), VF drops to 0.82V due to negative temperature coefficient, supporting stable performance under thermal stress.
Does MBR3080CT-Y require a heatsink in typical 30A applications?
Yes, the MBR3080CT-Y requires a heatsink for continuous 30A operation. With RθJC = 1.0°C/W and PD ≈ 28W (at 0.94V × 30A), junction temperature would exceed 150°C without thermal management. A standard TO-220 heatsink (RθSA ≈ 5°C/W) keeps TJ below 125°C at 30A, satisfying reliability requirements for industrial-grade designs.
What marking code appears on the MBR3080CT-Y device body?
The MBR3080CT-Y is laser-marked with "MBR3080CT" on the top surface, followed by date code (YWW format), factory code (F), and green compound indicator (G), per the Marking Diagram in the Taiwan Semiconductor datasheet. No suffix "-Y" appears on the physical device; the "-Y" denotes halogen-free compliance in ordering nomenclature only.
