Product details
Overview
MBR6040CT from Taiwan Semiconductor is a 60A, 40V dual-die Schottky barrier rectifier in TO-220AB package, designed for high-efficiency DC/DC conversion with low forward voltage (0.68V typ. @30A, 25°C), 250A surge capability, and AEC-Q101 qualification option. It serves as primary output rectification in automotive-grade SMPS and industrial adapters.
For engineers reviewing the MBR6040CT datasheet, MBR6040CT pinout, MBR6040CT application, or MBR6040CT equivalent, key selection factors include junction-to-case thermal resistance (0.5°C/W), repetitive peak reverse voltage (40V), forward current derating behavior, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
The MBR6040CT integrates two independent Schottky die in a single TO-220AB case with common cathode configuration, enabling dual-channel synchronous rectification without external paralleling. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Thermal performance is defined by RθJC = 0.5°C/W, supporting high-power operation up to TJ = 150°C. The device exhibits low dv/dt rating (10,000 V/μs) and reverse leakage of ≤100 µA at 25°C, critical for stable switching node behavior in high-frequency converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 60 A continuous per diode - supports high-output-current DC/DC stages without forced air cooling |
| Peak Reverse Voltage (VRRM) | 40 V - suitable for 36V nominal bus systems with margin against transients |
| Surge Current (IFSM) | 250 A (8.3 ms half-sine) - withstands inrush and fault currents in adapter front-ends |
| Forward Voltage (VF) | 0.68 V typ. @30A, 25°C - reduces conduction loss vs. silicon diodes, improving efficiency >92% in 12V→5V converters |
| Junction Temp Range | –55°C to +150°C - enables under-hood automotive deployment and industrial ambient operation |
| Thermal Resistance (RθJC) | 0.5°C/W - allows ~120W power dissipation with 60°C case-to-ambient delta using standard heatsink |
Pinout & Package
Package: TO-220AB, 3-terminal plastic case with isolated mounting tab (cathode-connected tab), UL 94V-0 rated molding compound, matte tin-plated leads, polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab / Pin 1 | Cathode (common) | Electrically connected to metal tab - must be electrically isolated from chassis unless used as common return path |
| Pin 2 | Anode 1 | Independent anode for first Schottky die - enables dual-output or phase-split rectification |
| Pin 3 | Anode 2 | Independent anode for second Schottky die - supports interleaved or redundant rectifier configurations |

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-MBR6040CT | Identical electrical specs (60A/40V), same TO-220AB package, but not AEC-Q101 qualified | Lacks automotive qualification - unsuitable for ASIL-B systems requiring stress-tested components | Select when cost sensitivity outweighs automotive qualification requirements |
| ON Semiconductor MBR6045CT | Higher VRRM (45V), identical IF/IFSM, slightly higher VF (0.75V typ. @30A) | Better transient margin for 42V battery systems; 3% efficiency penalty at full load due to VF increase | Choose for 48V nominal systems where 40V margin is insufficient |
Compared with VS-MBR6040CT and MBR6045CT, the MBR6040CT uniquely balances automotive qualification, thermal performance (0.5°C/W), and low VF for cost-sensitive high-volume 36–40V bus applications.

FAQ
What is the pin configuration of the MBR6040CT?
The MBR6040CT uses a TO-220AB package with three terminals: Pin 1 (metal tab) is the common cathode, Pin 2 is Anode 1, and Pin 3 is Anode 2. The tab is electrically connected to the cathode and must be isolated unless used as the circuit return path. Polarity is marked on the device top surface per TSC's standard marking diagram.
Is the MBR6040CT suitable for automotive applications?
Yes - the MBR6040CTH variant is AEC-Q101 qualified and tested per stress requirements for automotive use. While the base MBR6040CT is not qualified, its thermal and electrical specs (–55°C to +150°C, 250A IFSM, guard ring) align with automotive design margins. For ASIL-compliant systems, specify MBR6040CTH.
What is the maximum power dissipation capability of the MBR6040CT?
With RθJC = 0.5°C/W and TJMAX = 150°C, the MBR6040CT can dissipate up to ~120W when mounted on a heatsink maintaining TC ≤ 90°C. At 60A and VF = 0.92V (max @25°C), conduction loss is 55.2W - leaving significant margin for transient surges and ambient derating.
How does the MBR6040CT compare to silicon rectifiers in efficiency?
The MBR6040CT achieves 0.68V typical forward voltage at 30A/25°C - roughly half the VF of equivalent silicon diodes. This cuts conduction losses by ~50%, directly improving converter efficiency by 2–3% in 12V→5V SMPS and reducing thermal management complexity in space-constrained adapters.
Does the MBR6040CT require a heatsink in standard operation?
Yes - at 60A continuous current, the MBR6040CT generates ≥40W of heat even at optimal VF. Without a heatsink, junction temperature exceeds 150°C within seconds. A minimum 25 cm² aluminum heatsink with thermal interface material is required for sustained 60A operation at 25°C ambient.
