Product details
Overview
MBR4060WT from Vishay is a center-tap dual Schottky rectifier in TO-247AC package, rated for 2 × 20 A average forward current per leg and 60 V reverse voltage, with 0.62 V forward voltage at 20 A and 125 °C junction temperature, optimized for high-frequency switching power supplies and reverse battery protection.
For engineers reviewing the MBR4060WT datasheet, MBR4060WT pinout, MBR4060WT application, or MBR4060WT equivalent, key selection criteria include its center-tap configuration, 150 °C maximum junction temperature, low VF (0.62 V @ 20 A/125 °C), 1020 A non-repetitive surge rating, and thermal resistance of 2.20 °C/W (junction-to-case).
Technical Context
The MBR4060WT integrates two independent Schottky diode legs sharing a common cathode terminal, enabling center-tap full-wave rectification without external interconnection. Its proprietary barrier technology enables stable operation up to 150 °C TJ while maintaining low leakage (100 mA @ 125 °C) and fast recovery (dV/dt = 10,000 V/µs).
Thermally, it features a low RthJC of 2.20 °C/W and uses high-purity, high-temperature epoxy encapsulation with guard ring structure-designed specifically for industrial-level reliability under sustained high-current, high-temperature conditions in DC/DC converters and freewheeling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 20 A at TC = 108 °C, 50 % duty cycle - supports continuous high-current output in compact heatsinked designs |
| VRRM | 60 V - suitable for 48 V nominal bus systems with safety margin against transients |
| VF @ 20 A / 125 °C | 0.62 V - reduces conduction loss by ~30 % vs. standard silicon rectifiers at same current |
| IFSM (per leg) | 1020 A @ 5 µs sine - withstands severe inrush and short-circuit surge events |
| RthJC | 2.20 °C/W - enables efficient heat transfer to heatsink, critical for high-power density layouts |
| IRM @ 125 °C | 100 mA - moderate leakage maintained at elevated temperature for stable reverse blocking |
| TJ range | -55 to +150 °C - qualified for extended industrial ambient and internal heating conditions |

Applications
| Switching Power Supplies | DC/DC Converters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48 V input telecom or server PSUs operating at 100–500 kHz. IC Role / Device Role / Timing Role: Center-tap Schottky rectifier providing low-loss, high-efficiency DC output generation.

IC Role / Device Role / Timing Role: Low-loss reverse-blocking element placed in series with main power input. Use Value: 60 V VR rating covers load-dump transients up to ISO 7637-2 Pulse 5a, while 100 mA IRM @ 125 °C ensures minimal standby drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay MBR4060CT | Same die, identical electrical specs, but TO-220AB package with separate cathodes (not center-tap); no common cathode terminal | Requires external parallel connection for center-tap use; unsuitable for single-package full-wave rectification | Select MBR4060WT when board space and layout simplicity demand integrated center-tap topology |
| ON Semiconductor MUR460CT | Ultrafast silicon rectifier (not Schottky); VF ≈ 1.7 V @ 20 A; higher switching loss; 175 °C TJ max | Higher conduction loss and EMI due to minority-carrier recovery; used where cost outweighs efficiency | Choose only if Schottky leakage sensitivity or thermal constraints preclude MBR4060WT |
Compared with MBR4060CT and MUR460CT, the MBR4060WT uniquely delivers center-tap integration, Schottky-level VF, and industrial thermal robustness in one TO-247AC package-making it optimal for high-efficiency, high-reliability full-wave rectification where layout simplicity and thermal performance are critical.

FAQ
What is the pin configuration of the MBR4060WT?
The MBR4060WT uses a TO-247AC package with three terminals: Terminal 1 is Anode 1, Terminal 2 is the Common Cathode shared by both legs, and Terminal 3 is Anode 2. This center-tap arrangement enables full-wave rectification without external interconnects, and the pinout is verified in Vishay Document Number 93453, Figure on page 2.
Does the MBR4060WT support operation at 150 °C junction temperature?
Yes, the MBR4060WT is explicitly rated for 150 °C maximum junction temperature, with all key parameters-including VF (0.62 V @ 20 A), IRM (100 mA), and RthJC (2.20 °C/W)-specified and qualified at that limit. Its guard ring and high-temperature epoxy ensure reliability under sustained 150 °C TJ conditions.
Is the MBR4060WT RoHS-compliant and lead-free?
Yes, the MBR4060WT is lead (Pb)-free and RoHS-compliant, as confirmed in the Vishay ordering information table (Document Number 93453, page 5), where "WT" suffix denotes Pb-free TO-247AC packaging. Full compliance documentation is available via Vishay's part marking information document #95226.
How does the MBR4060WT compare to standard silicon rectifiers in efficiency?
The MBR4060WT achieves 0.62 V forward voltage at 20 A and 125 °C-roughly 65 % lower than typical silicon rectifiers (~1.7 V). This directly reduces conduction loss, improves thermal performance, and increases overall system efficiency, especially in high-frequency, high-current applications like telecom PSUs and PoL converters.
Can the MBR4060WT be used in reverse battery protection circuits?
Yes, the MBR4060WT is commonly deployed in reverse battery protection due to its 60 V VR rating (covering ISO 7637-2 load-dump transients), low 100 mA IRM at 125 °C (minimizing standby current), and robust 1020 A IFSM (withstanding jump-start surges). Its Schottky architecture eliminates minority-carrier recovery delay, ensuring immediate blocking.
