Product details
Overview
MBRS4060CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 40 A average forward current and 60 V repetitive peak reverse voltage, with 300 A surge capability and 1.5 °C/W junction-to-case thermal resistance-used in automotive DC/DC converters and reverse battery protection circuits.
For engineers reviewing the MBRS4060CTH datasheet, MBRS4060CTH pinout, MBRS4060CTH application, or MBRS4060CTH equivalent, key selection criteria include its AEC-Q101 qualification, low VF (≤1.00 V @ 40 A, 25°C), high TJ max (175°C), moisture sensitivity level 1, and dual-die configuration enabling shared thermal path in compact layouts.
Technical Context
This dual-die Schottky rectifier integrates two independent 60 V / 40 A diodes in a single TO-263AB thermally optimized package, sharing a common cathode configuration (CT suffix). Its guard ring structure enhances dv/dt immunity (10,000 V/μs), while matte tin-plated leads ensure J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Designed for high-frequency switching environments, MBRS4060CTH delivers low conduction loss (VF ≤ 0.90 V @ 40 A, 125°C) and minimal reverse recovery charge-critical for efficiency in 100–500 kHz DC/DC topologies-and operates across -55°C to +175°C junction temperature range with UL 94V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 40 A - supports continuous high-current output stages in automotive DC/DC converters without forced air cooling |
| VRRM | 60 V - compatible with 48 V nominal battery systems and transient clamping up to ISO 7637-2 Pulse 5a |
| IFSM (8.3 ms) | 300 A - withstands load dump surges in vehicle electrical systems without failure |
| TJ max | 175 °C - enables operation in under-hood environments with minimal derating |
| RθJC | 1.5 °C/W - allows direct heatsinking to PCB copper or external metal slug for thermal management |
| VF @ 40 A, 25°C | ≤1.00 V - reduces conduction loss by ~30% vs. comparable Si fast recovery diodes at same current |
| Moisture Sensitivity | Level 1 (J-STD-020) - no bake required before SMT reflow, simplifying manufacturing |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal case with exposed thermal pad. Cathode common configuration (CT): Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Connects to input/high-side node in freewheeling or reverse polarity protection path |
| Pin 2 | Common Cathode | Shared output/return node; electrically and thermally tied to exposed metal tab for low-inductance grounding |
| Pin 3 | Anode of Diode 2 | Enables dual-channel independent routing-e.g., separate buck converter phases or redundant protection paths |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test conditions |
| Guard ring structure | Improves ruggedness against overvoltage transients (dv/dt = 10,000 V/μs), reducing risk of edge breakdown |
| Dual-die, common-cathode | Enables space-efficient dual-path rectification with shared thermal interface-no need for two discrete D2PAKs |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained supply chains |
| Matte tin plating | Ensures reliable solder wetting and intermetallic formation per J-STD-002, eliminating lead-free solder voiding risks |

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-MBR4060CT-M3 | Same TO-263AB package, 40 A/60 V rating, but RθJC = 1.7 °C/W; VF slightly higher (1.05 V @ 40 A, 25°C) | Marginally lower thermal performance limits peak pulse duty cycle in high-ambient designs | Acceptable where board-level heatsinking is enhanced or ambient < 105°C |
| ON Semiconductor MBR4060CT | Identical electrical specs and TO-263AB footprint, but not AEC-Q101 qualified; MSL level 3 vs. level 1 | Not suitable for automotive production without additional qualification testing | Select MBRS4060CTH when automotive qualification and zero-bake assembly are mandatory |
Compared with VS-MBR4060CT-M3 and MBR4060CT, MBRS4060CTH offers superior thermal resistance (1.5 vs. 1.7 °C/W), guaranteed AEC-Q101 compliance, and MSL level 1-making it the only choice for volume automotive applications requiring zero process risk and extended under-hood lifetime.

FAQ
What is the marking code printed on the MBRS4060CTH device?
The MBRS4060CTH device is marked "MBRS4060CT" on its top surface, followed by date code (YWW format), factory code (F), and green compound indicator (G). This matches the ordering code prefix and confirms authenticity per Taiwan Semiconductor's standard marking convention for TO-263AB devices.
Does MBRS4060CTH support reflow soldering without moisture preconditioning?
Yes, MBRS4060CTH has moisture sensitivity level 1 per J-STD-020, meaning it can be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D peak 260°C) without baking-even after indefinite dry pack storage. This eliminates pre-reflow bake steps and reduces manufacturing cost and risk of oxidation.
What is the maximum allowable case temperature for continuous operation of MBRS4060CTH?
The MBRS4060CTH does not specify a standalone maximum case temperature, but its absolute maximum junction temperature is 175°C and RθJC is 1.5 °C/W. For 40 A continuous operation with 1.00 V forward drop, power dissipation is ~40 W; thus, maximum sustainable case temperature is ~115°C (175°C − 40 W × 1.5 °C/W) assuming ideal heatsinking-verified via Fig.1 derating curve.
Is MBRS4060CTH suitable for reverse polarity protection in 48 V battery systems?
Yes, MBRS4060CTH is explicitly designed for reverse battery protection in automotive applications. Its 60 V VRRM provides 25% margin above 48 V nominal systems, and its 300 A IFSM handles jump-start surges. The AEC-Q101 qualification and 175°C TJ max further validate suitability for under-hood deployment in such systems.
How does the guard ring in MBRS4060CTH improve robustness?
The guard ring in MBRS4060CTH is a diffused p-type region surrounding the active Schottky junction, which distributes electric field gradients during voltage transients. This raises the critical dv/dt rating to 10,000 V/μs-preventing localized avalanche and premature breakdown during load dump or inductive switching events common in automotive power networks.
