Product details
Overview
MBRB2545CTTRL from Vishay is a dual common-cathode Schottky rectifier in D2PAK package, rated for 2 × 15 A average forward current per leg, 45 V reverse voltage, and 0.73 V forward voltage at 30 A and 125 °C - optimized for high-efficiency DC/DC converters and reverse battery protection circuits.
For engineers reviewing the MBRB2545CTTRL datasheet, MBRB2545CTTRL pinout, MBRB2545CTTRL application, or MBRB2545CTTRL equivalent, key selection criteria include thermal resistance (1.5 °C/W per leg), low IRM (40 mA at 125 °C), rugged guard-ring construction, Q101 qualification, and D2PAK tape-and-reel packaging for automated assembly.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal, enabling center-tap configuration for synchronous rectification or dual-path freewheeling. Its proprietary barrier technology ensures stable operation up to 150 °C junction temperature with low reverse leakage and high dV/dt capability (10,000 V/µs).
The D2PAK package provides low thermal resistance (RthJC = 1.5 °C/W per leg) and mechanical robustness via high-purity epoxy encapsulation. It supports high-frequency switching (>100 kHz) due to low junction capacitance (700 pF at 5 V) and minimal series inductance (8.0 nH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 15 A at TC = 130 °C - defines continuous DC current handling per anode under heatsink-cooled conditions |
| VRRM | 45 V - maximum non-repetitive peak reverse voltage the device blocks reliably |
| VF at 30 A, 125 °C | 0.73 V - determines conduction loss in high-temp power stages; enables >92 % efficiency in 12 V output converters |
| IRM at 125 °C | 40 mA - reverse leakage directly impacts standby power loss and thermal runaway risk in battery-connected systems |
| RthJC per leg | 1.5 °C/W - enables compact heatsink design; 22.5 W dissipation per leg before reaching 150 °C TJ limit |
| dV/dt rating | 10,000 V/µs - supports fast-switching topologies without spurious turn-on in noisy environments |
| Junction temp range | –65 to +150 °C - qualified for under-hood automotive and industrial ambient conditions |
Pinout & Package
D2PAK (TO-263) surface-mount package with 3 terminals: Pin 1 (Anode 1), Pin 2 (Common Cathode), Pin 3 (Anode 2). Molded epoxy body, copper leadframe, and exposed thermal pad on underside for PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input path for first rectifying leg; connects to primary-side switch node in half-bridge or flyback secondary |
| Pin 2 | Common Cathode | Shared output node for both legs; must be routed to low-inductance ground/power plane for EMI control |
| Pin 3 | Anode 2 | Input path for second rectifying leg; enables dual-output or interleaved converter designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay MBRB2545CTR | Tape-and-reel orientation unspecified; TRL denotes left-oriented reel - critical for pick-and-place nozzle alignment | Same electrical specs and D2PAK footprint; differs only in reel packaging direction | Select MBRB2545CTTRL when using vision-guided feeders requiring left-edge tape registration |
| ON Semiconductor NTS2545CT | Higher VF (0.78 V @ 30 A, 125 °C); RthJC = 1.7 °C/W; no Q101 qualification | Suitable for commercial-grade PSUs but not automotive under-hood use due to lower temp rating and reliability validation | Choose NTS2545CT only for cost-sensitive non-automotive designs where 50 mV higher VF and 0.2 °C/W higher thermal resistance are acceptable |
Compared with MBRB2545CTTRL, MBRB2545CTR offers identical performance but requires reel orientation verification, while NTS2545CT trades automotive qualification and thermal efficiency for lower procurement cost in non-critical applications.

FAQ
What is the maximum junction temperature rating for the MBRB2545CTTRL?
The MBRB2545CTTRL is rated for a maximum junction temperature (TJ) of +150 °C, validated through Q101 qualification testing. This allows reliable operation in under-hood automotive environments and high-power-density industrial converters. The device maintains low IRM (40 mA at 125 °C) and stable VF even near its thermal limit, making MBRB2545CTTRL suitable for thermally constrained designs where silicon alternatives would derate significantly.
Does the MBRB2545CTTRL have automotive qualification?
Yes, the MBRB2545CTTRL is designed and qualified to AEC-Q101 standards for discrete semiconductors. This includes stress tests for temperature cycling, humidity, high-temperature operating life, and ESD. Its guard ring structure, high-purity epoxy encapsulation, and 150 °C TJ rating align with automotive reliability requirements - confirming MBRB2545CTTRL for use in engine control units, ADAS power modules, and infotainment systems.
What does "TRL" signify in the MBRB2545CTTRL part number?
"TRL" in MBRB2545CTTRL indicates tape-and-reel packaging with left-oriented orientation - meaning the component tape advances with the device's marking side facing left when viewed from the feed direction. This is critical for vision-based pick-and-place machines that rely on consistent optical registration. Unlike tube-packaged variants, MBRB2545CTTRL supports high-speed SMT assembly without manual orientation checks.
How does the common-cathode configuration of the MBRB2545CTTRL benefit circuit design?
The common-cathode configuration of the MBRB2545CTTRL simplifies PCB layout for dual-path topologies like interleaved converters or dual-output supplies by reducing net count and eliminating cathode routing mismatches. With shared cathode (Pin 2), both anodes (Pins 1 and 3) can be independently switched while maintaining synchronized voltage reference - improving cross-regulation and reducing EMI compared to discrete diode solutions. This architecture is integral to MBRB2545CTTRL's role in high-efficiency power conversion.
What thermal interface considerations apply to the MBRB2545CTTRL D2PAK package?
The MBRB2545CTTRL uses a D2PAK package with an exposed thermal pad on the underside, requiring solder paste stencil design and reflow profile optimization to ensure void-free thermal attachment. Recommended minimum copper area is 25 mm² per leg with thermal vias (≥6×0.3 mm) to inner ground planes. With RthJC = 1.5 °C/W per leg, proper thermal pad connection lowers junction-to-board resistance by >60 % versus standard land patterns - essential for sustaining full 15 A per leg in MBRB2545CTTRL applications.
