Product details
Overview
VS-MBRB2080CTPBF from Vishay Semiconductors is a high-performance dual common-cathode Schottky rectifier in D2PAK (TO-263AB) package, rated for 2 × 10 A average forward current per leg, 80 V maximum reverse voltage, and 0.70 V forward voltage at 10 A and 125 °C. It operates up to 150 °C junction temperature and delivers low reverse leakage, making it suitable for high-efficiency DC/DC converters and automotive power supplies.
For engineers reviewing the VS-MBRB2080CTPBF datasheet, VS-MBRB2080CTPBF pinout, VS-MBRB2080CTPBF application, or VS-MBRB2080CTPBF equivalent, key selection criteria include its 80 V VR rating, 2.0 °C/W thermal resistance per leg, AEC-Q101 qualification, and center-tap dual-die configuration optimized for synchronous rectification and reverse battery protection.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling dual-channel freewheeling or parallel rectification in compact layouts. Its proprietary barrier technology ensures stable operation at TJ = 150 °C with IRM ≤ 6 mA at 125 °C and VF = 0.70 V under rated conditions.
The D2PAK package provides low RthJC (2.0 °C/W per leg), high surge capability (IFSM = 850 A), and MSL Level 1 moisture sensitivity - validated for lead-free reflow up to 260 °C peak. Guard ring design enhances ruggedness against transient overstress and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 80 V - Maximum DC reverse blocking voltage per leg; defines safe operating range in buck converter outputs or reverse polarity protection circuits. |
| IF(AV) | 2 × 10 A - Average forward current per leg at TC = 133 °C; supports high-power 12 V/24 V automotive and industrial SMPS designs. |
| VFM | 0.70 V @ 10 A, 125 °C - Low conduction loss enables >95% efficiency in high-frequency switching applications. |
| RthJC | 2.0 °C/W per leg - Enables direct heatsink mounting with minimal thermal derating; critical for sustained 20 A total output in space-constrained systems. |
| EAS | 8.0 mJ per leg - Avalanche energy rating supports robustness during inductive load switching transients without failure. |
| dV/dt | 10,000 V/μs - High voltage slew rate immunity prevents false turn-on in fast-switching topologies like LLC resonant converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS20H80CGY | Same 80 V VR, 20 A total, TO-220AC package; higher VF = 0.82 V @ 10 A, 125 °C; no AEC-Q101 qualification. | Not qualified for automotive use; limited to industrial/commercial power supplies with lower thermal constraints. | Select when D2PAK footprint is unavailable and lower-cost through-hole assembly is preferred. |
| ON Semiconductor MBR2080CT | Identical 80 V/20 A rating and D2PAK package; VF = 0.72 V @ 10 A, 125 °C; no AEC-Q101 or guard ring; MSL Level 3. | Lacks automotive qualification and enhanced ruggedness features; higher moisture sensitivity requires stricter handling. | Choose for cost-sensitive non-automotive designs where AEC-Q101 and guard ring are not required. |
Compared with STPS20H80CGY and MBR2080CT, VS-MBRB2080CTPBF offers the only combination of AEC-Q101 qualification, guard ring ruggedness, MSL Level 1, and lowest VF (0.70 V) at 125 °C - making it the preferred choice for thermally demanding automotive and industrial applications requiring long-term reliability.

FAQ
What is the maximum junction temperature rating for VS-MBRB2080CTPBF?
The VS-MBRB2080CTPBF has a maximum junction temperature (TJ) of +150 °C, verified per AEC-Q101 stress testing. This rating allows continuous operation in under-hood automotive environments and high-ambient industrial settings without thermal derating below 10 A per leg at TC = 133 °C. The device maintains stable VF and IRM performance up to this limit.
Is VS-MBRB2080CTPBF pin-compatible with other Vishay dual Schottky rectifiers in D2PAK?
Yes, VS-MBRB2080CTPBF uses the standard D2PAK (TO-263AB) outline with identical pin assignment: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. It shares mechanical and thermal footprint compatibility with VS-MBRB2090CTPBF and VS-MBRB20100CTPBF, enabling voltage-scaling design reuse without PCB changes.
Does VS-MBRB2080CTPBF require a heatsink in typical 20 A applications?
VS-MBRB2080CTPBF achieves RthJC = 2.0 °C/W per leg, so a heatsink is recommended for continuous 20 A operation above ambient temperatures >60 °C. At TC = 133 °C, it sustains 10 A per leg without external heatsinking; however, for full 20 A total current, a low-thermal-resistance heatsink or copper pour is necessary to maintain TJ ≤ 150 °C.
What is the reverse leakage current specification for VS-MBRB2080CTPBF at elevated temperature?
At TJ = 125 °C and rated VR = 80 V, the VS-MBRB2080CTPBF specifies IRM ≤ 6 mA per leg. This low leakage - enabled by Vishay's proprietary barrier technology - ensures minimal standby power loss in battery-powered systems and stable regulation in high-temperature DC/DC converters.
How does the guard ring feature improve reliability of VS-MBRB2080CTPBF?
The guard ring in VS-MBRB2080CTPBF enhances edge termination robustness, preventing premature avalanche breakdown under high dv/dt stress or localized mechanical strain. This design significantly improves long-term reliability in automotive applications subject to vibration, thermal cycling, and electrical transients - a key factor in its AEC-Q101 qualification.
