Product details
Overview
MBRF3080CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 30A average forward current and 80V repetitive peak reverse voltage, with 200A surge capability and 5°C/W junction-to-case thermal resistance-used in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBRF3080CT datasheet, MBRF3080CT pinout, MBRF3080CT application, or MBRF3080CT equivalent, key selection criteria include forward voltage at 30A/125°C (0.82 V), reverse leakage at 125°C (10 mA), AEC-Q101 qualification availability, UL recognition (E-326243), and ITO-220AB mounting torque limit (0.56 N·m).
Technical Context
The MBRF3080CT integrates two independent Schottky diodes in a single ITO-220AB thermally enhanced package with guard ring structure for dv/dt robustness up to 10,000 V/µs and JESD201 Class 2 whisker resistance. Its dual-die configuration enables common-cathode or common-anode parallel operation depending on PCB layout.
Designed for high-frequency switching applications, it delivers low conduction loss (VF ≤ 0.94 V @ 30A, 25°C) and fast recovery (no stored charge), with thermal performance validated by RθJC = 5°C/W and operating junction temperature range of –55°C to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 30 A - supports continuous output current in 300–500W SMPS designs without forced air cooling |
| VRRM | 80 V - suitable for 48V bus systems with 20% safety margin against transient overvoltage |
| IFSM (8.3ms) | 200 A - withstands inrush surges during cold-start of DC/DC modules and adapters |

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-30CPQ080 | Same 30A/80V rating, TO-220AC package (single anode), RθJC = 4.5°C/W, VF = 0.87 V @ 30A/25°C | Lacks dual-die configuration; not suitable for common-cathode dual-output topologies | Select when single-anode layout simplifies PCB routing and thermal management is prioritized over dual functionality |
| ON Semiconductor MBR30H80CT | Identical ITO-220AB package and dual-die structure; AEC-Q101 qualified; VF = 0.85 V @ 30A/25°C; IR = 8 mA @ 125°C | Higher cost; tighter IR spec beneficial in low-power standby modes | Prefer for automotive designs requiring full AEC-Q101 compliance out-of-box, especially where leakage-driven standby power is critical |
Compared with MBRF3080CT, VS-30CPQ080 offers slightly better thermal resistance but sacrifices dual-anode flexibility, while MBR30H80CT provides guaranteed AEC-Q101 qualification and lower high-temp leakage-making it preferable for automotive, whereas MBRF3080CT balances cost and dual functionality for industrial SMPS.

FAQ
What is the maximum junction temperature rating for the MBRF3080CT?
The MBRF3080CT has a maximum junction temperature (TJ) rating of +150°C, with a minimum of –55°C. This wide operating range allows use in harsh environments such as enclosed industrial enclosures or under-hood automotive locations. The device maintains specified electrical performance across this full range, and its 5°C/W RθJC enables reliable thermal management when mounted to an appropriately sized heatsink. Always verify actual junction temperature using thermal simulation or measurement in final application.
Is the MBRF3080CT pin-compatible with other ITO-220AB dual Schottky rectifiers?
Yes-the MBRF3080CT uses standard ITO-220AB pinout: Tab = Cathode, Lead 1 = Anode 1, Lead 2 = Anode 2. It is mechanically and electrically compatible with industry-standard ITO-220AB footprints, including those used by ON Semiconductor MBR30H80CT and Diodes Inc. SB3080CT. However, always confirm thermal pad clearance, mounting hole alignment, and solder mask definition per your PCB stack-up before layout reuse.
Does the MBRF3080CT have AEC-Q101 qualification?
The base MBRF3080CT is not AEC-Q101 qualified; however, the variant MBRF3080CTH is fully AEC-Q101 qualified per Rev. E2105 documentation. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. For automotive applications requiring formal qualification, specify MBRF3080CTH-not MBRF3080CT-to ensure compliance with automotive reliability standards.
What is the forward voltage drop of the MBRF3080CT at full rated current and elevated temperature?
At 30A and 125°C, the MBRF3080CT exhibits a maximum forward voltage (VF) of 0.82 V per diode, as specified in the Electrical Specifications table. This value reflects real-world conduction loss under thermal stress and is critical for calculating efficiency and thermal rise in high-load DC/DC converters. At 25°C and 30A, VF is ≤ 0.94 V-demonstrating strong temperature coefficient behavior typical of Schottky architecture.
How does the guard ring feature improve reliability in the MBRF3080CT?
The guard ring in the MBRF3080CT enhances edge termination robustness, raising the critical dv/dt rating to 10,000 V/µs. This prevents spurious conduction during fast voltage transients common in high-frequency SMPS and synchronous rectifier circuits. In practice, this eliminates false triggering in 500 kHz+ converters and improves immunity to line-induced spikes-directly extending device lifetime in noisy industrial power systems where the MBRF3080CT is deployed.
