Product details
Overview
MBRS2545CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 45 V repetitive peak reverse voltage, and 200 A non-repetitive surge current; it delivers low forward voltage (0.65 V typ. at 12.5 A, 25°C) and operates up to 150°C junction temperature, ideal for automotive DC/DC converters requiring high efficiency and AEC-Q101 qualification.
For engineers reviewing the MBRS2545CTH datasheet, MBRS2545CTH pinout, MBRS2545CTH application, or MBRS2545CTH equivalent, key selection criteria include its 45 V VRRM, dual-common-cathode configuration, thermal resistance of 1°C/W (junction-to-case), AEC-Q101 qualification, and suitability for reverse battery protection and freewheeling in high-frequency power supplies.
Technical Context
The MBRS2545CTH integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, enabling synchronous rectification or dual-path freewheeling. Its guard ring structure enhances overvoltage ruggedness, while the low 0.65 V forward voltage at 12.5 A reduces conduction losses in low-voltage, high-current topologies.
Designed for automotive-grade reliability, it meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, with a 150°C maximum junction temperature and 10,000 V/μs critical dv/dt rating-supporting stable operation in noisy, fast-switching environments such as engine control modules and LED driver circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage per diode; defines safe operating range in 12–24 V automotive systems with transient margin. |
| IF | 25 A - Continuous average forward current per diode; supports high-power DC/DC stages without forced air cooling. |
| VF (typ) | 0.65 V @ 12.5 A, 25°C - Low conduction loss enables >92% efficiency in 5–12 V output converters. |
| IFSM | 200 A - Peak surge rating for 8.3 ms half-sine; withstands load dump and cold-crank transients in vehicle electrical systems. |
| RθJC | 1°C/W - Enables direct thermal coupling to PCB copper pour or heatsink; simplifies thermal design for 25 A operation. |
| TJ max | 150°C - Allows operation in under-hood environments without derating below full current. |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal case with exposed anode tab (Pin 1), common cathode (Pin 2), and second anode (Pin 3). Molding compound meets UL 94V-0; matte tin-plated leads comply with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | First diode anode | Connects to input/high-side switching node; electrically isolated from Pin 3 but shares thermal pad. |
| Pin 2 (Cathode) | Common cathode | Shared output node for both diodes; must be routed with low-inductance path to minimize ringing in high-dI/dt applications. |
| Pin 3 (Anode 2) | Second diode anode | Enables dual-path rectification or independent freewheeling; identical electrical specs to Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTOL, TC, UHAST, and ESD-no additional qualification needed for Tier-1 designs. |
| Guard ring structure | Improves edge termination robustness, raising actual breakdown voltage beyond 45 V and reducing risk of premature failure during voltage transients. |
| Low VF at high TJ | 0.73 V @ 25 A, 125°C - Maintains efficiency in hot environments where silicon diodes would degrade significantly. |
| Moisture sensitivity level 1 | No bake requirement before reflow; compatible with standard SMT assembly lines without special handling or dry pack. |

FAQ
What is the maximum junction temperature rating for MBRS2545CTH?
The MBRS2545CTH has a maximum junction temperature (TJ) of +150°C, verified per AEC-Q101 stress testing. This rating allows uninterrupted 25 A operation in ambient temperatures up to 100°C when mounted on a 1-in² 2-oz copper thermal pad, making it suitable for under-hood automotive environments where thermal management is constrained.
Is MBRS2545CTH pin-compatible with other parts in the MBRS25xxCTH family?
Yes, all MBRS25xxCTH variants-including MBRS2535CTH, MBRS2545CTH, MBRS2550CTH, and up to MBRS25150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. Engineers may substitute within the family based on required VRRM without modifying PCB footprint or assembly process.
Does MBRS2545CTH support automated SMT placement?
Yes, MBRS2545CTH is optimized for automated placement per its mechanical data: it features matte tin-plated leads compliant with J-STD-002, Level 1 moisture sensitivity (no baking required), and a standardized TO-263AB outline. Its 1.37 g weight and symmetrical terminal geometry ensure reliable pick-and-place yield in high-volume manufacturing.
What is the reverse leakage current specification for MBRS2545CTH at 125°C?
At 125°C junction temperature and rated 45 V reverse voltage, the MBRS2545CTH exhibits a maximum reverse current (IR) of 15 mA per diode, as specified in the Electrical Specifications table. This value reflects worst-case leakage under high-temperature stress and remains well below thermal runaway thresholds in properly designed PCB layouts.
How does the guard ring feature improve reliability in MBRS2545CTH?
The guard ring in MBRS2545CTH provides enhanced edge termination for the Schottky junction, increasing effective breakdown voltage margin and suppressing premature avalanche at device periphery. This improves robustness against voltage transients-such as ISO 7637-2 pulse 1 and pulse 5a-and extends operational life in automotive power rails subject to frequent load dumps and cranking events.
