Product details
Overview
MBRS6040CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 60 A average forward current and 40 V repetitive peak reverse voltage, with 250 A surge capability and 1.05 V max forward voltage at 60 A/25°C - used as freewheeling diode in automotive DC/DC converters.
For engineers reviewing the MBRS6040CTH datasheet, MBRS6040CTH pinout, MBRS6040CTH application, or MBRS6040CTH equivalent, key selection factors include junction-to-case thermal resistance (1°C/W), AEC-Q101 qualification, moisture sensitivity level 1, and dual-die configuration enabling shared thermal path in high-current synchronous rectification.
Technical Context
This dual-die Schottky rectifier integrates two independent 40 V/60 A diodes in a single TO-263AB thermally optimized package, sharing a common cathode connection. Its low VF (≤1.05 V @ 60 A, 25°C) and high dv/dt rating (10,000 V/μs) support fast-switching topologies in 48 V automotive subsystems.
The device operates across –55°C to +150°C junction temperature range, features guard ring overvoltage protection, and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21 - critical for under-hood power conversion reliability.
Key Specifications

| IFSM (8.3 ms) | 250 A - withstands load dump and cranking surge events in vehicle power rails |
| RθJC | 1 °C/W - enables direct heatsink mounting for thermal management in compact engine-control modules |
| TJ Range | –55°C to +150°C - qualified for under-hood placement in passenger and commercial vehicles |
| Moisture Sensitivity | Level 1 (J-STD-020) - allows standard SMT reflow without baking preconditioning |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal case with exposed copper thermal pad. Cathode common configuration: Pins 1 and 2 are anodes; Pin 3 is shared cathode (tab).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First diode anode | Connects to switching node of first half-bridge leg in dual-phase synchronous rectifier |
| Pin 2 (Anode B) | Second diode anode | Connects to switching node of second half-bridge leg; electrically isolated from Pin 1 |
| Pin 3 (Cathode) | Common cathode (tab) | Thermally and electrically tied to exposed metal pad; must be soldered to large PCB copper pour for heat dissipation |

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-MBR6045CT | 45 V VRRM, same TO-263AB package, 1.1 V VF max @ 60 A/25°C | Slightly higher reverse voltage margin but higher conduction loss | Preferred where system transients exceed 40 V but thermal budget allows +0.05 V VF penalty |
| ON Semiconductor MBR6045CT | 45 V VRRM, 1.08 V VF max @ 60 A/25°C, non-AEC-Q101 | Lacks automotive qualification; lower surge rating (200 A IFSM) | Suitable for industrial DC/DC where AEC-Q101 is not mandated and cost sensitivity outweighs qualification needs |
Compared with VS-MBR6045CT and MBR6045CT, the MBRS6040CTH delivers lower forward voltage at high current and certified AEC-Q101 reliability - making it optimal for thermally constrained, safety-critical automotive power stages where 40 V reverse margin is sufficient.

FAQ
What is the pin configuration of the MBRS6040CTH?
The MBRS6040CTH uses a three-terminal TO-263AB (D2PAK) package with Pin 1 and Pin 2 as independent anodes, and Pin 3 (exposed tab) as the common cathode. The marking "MBRS6040CT" appears adjacent to Pin 1. This configuration supports dual-phase synchronous rectification with shared thermal mass.
Is the MBRS6040CTH suitable for automotive applications?
Yes, the MBRS6040CTH is AEC-Q101 qualified and specified for operation from –55°C to +150°C junction temperature. It meets JESD201 Class 2 whisker resistance, RoHS, and halogen-free requirements - making MBRS6040CTH appropriate for under-hood DC/DC converters and lighting control modules.
What is the maximum forward voltage drop for the MBRS6040CTH at full rated current?
The MBRS6040CTH has a maximum forward voltage of 1.05 V at 60 A and 25°C junction temperature, and 0.98 V at 60 A and 125°C. These values are measured under pulsed conditions (PW = 0.3 ms) and reflect real-world conduction loss in high-current automotive power stages.
Does the MBRS6040CTH require special handling during PCB assembly?
No special handling is required: MBRS6040CTH has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be mounted using standard lead-free reflow profiles without pre-baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the TO-263AB package supports automated pick-and-place.
How does the guard ring in the MBRS6040CTH improve reliability?
The guard ring in the MBRS6040CTH mitigates edge breakdown during voltage transients by distributing electric field stress away from the active junction periphery. This design feature enhances robustness against ISO 7637-2 pulse 5a load-dump events and improves long-term reliability in automotive power rails where overvoltage spikes are common.
