Product details
Overview
MBRS2045CT from Taiwan Semiconductor is a 20A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 45V repetitive peak reverse voltage (VRRM), 150A surge current (IFSM), and maximum junction temperature of 150°C. It delivers low forward voltage drop (0.65V typ. at 10A/25°C) and is optimized for high-efficiency switching power supplies.
For engineers reviewing the MBRS2045CT datasheet, MBRS2045CT pinout, MBRS2045CT application, or MBRS2045CT equivalent, key selection criteria include its 45V VRRM rating, dual-common-cathode configuration, thermal resistance (RθJC = 1.5°C/W), and suitability for compact, high-current DC-DC converter outputs.
Technical Context
This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its guard ring structure provides overvoltage protection, and it meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
The MBRS2045CT operates across -55°C to +150°C junction temperature range, supports 10,000 V/μs critical dv/dt rating, and exhibits low reverse leakage (≤100 µA at 25°C, ≤15 mA at 125°C) - enabling stable performance in high-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum reverse blocking voltage per diode; defines safe operating limit in flyback or synchronous rectifier circuits |
| IF(AV) | 20 A - Average forward current per diode; supports continuous high-current output stages without forced cooling |
| IFSM | 150 A - Non-repetitive surge capability; withstands inrush and transient overload in power adapters |
| VF @ 10A/25°C | 0.65 V max - Low conduction loss improves system efficiency and reduces thermal stress in 12V–24V DC-DC converters |
| RθJC | 1.5 °C/W - Enables direct heatsinking to PCB copper; allows >15W dissipation with moderate copper area |
| IR @ 45V/25°C | 100 µA max - Minimal leakage preserves standby efficiency in energy-sensitive applications like USB PD adapters |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal case with exposed thermal pad. Cathode terminals are internally joined; anode pins are electrically isolated.

|---|---|---|
| Pin 1 (Anode A) | First diode anode | Connects to input/high-side node in dual-output or interleaved rectification |
| Pin 2 (Cathode) | Common cathode | Serves as shared output node; must be routed to large copper pour for thermal management |
| Pin 3 (Anode B) | Second diode anode | Enables independent control or parallel operation; used in center-tapped transformer secondary rectification |
Key Features

FAQ
What is the pin configuration of MBRS2045CT?
The MBRS2045CT uses a 3-pin TO-263AB (D2PAK) package with Pin 1 = Anode A, Pin 2 = Common Cathode, and Pin 3 = Anode B. This dual-anode, single-cathode arrangement supports full-wave rectification and parallel operation. The exposed thermal pad is electrically connected to the cathode and must be soldered to a large copper area for thermal performance.
Does MBRS2045CT support high-temperature operation?
Yes, MBRS2045CT is rated for junction temperatures from -55°C to +150°C. Its 150°C maximum rating allows reliable operation in sealed enclosures or high-ambient environments such as industrial motor drives and server VRMs. Derating curves confirm 20A average current is maintainable up to 110°C case temperature with adequate heatsinking.
What is the reverse leakage behavior of MBRS2045CT at elevated temperature?
At 45V reverse bias and 125°C junction temperature, MBRS2045CT exhibits ≤15 mA reverse current per diode. This is significantly lower than standard silicon rectifiers and ensures minimal standby power loss in energy-efficient designs like USB-C PD adapters and IoT power modules.
Is MBRS2045CT compatible with lead-free reflow processes?
Yes, MBRS2045CT features matte tin-plated leads qualified per J-STD-002 and is rated for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ambient conditions and processed using standard Pb-free reflow profiles (peak 260°C) without baking or special handling.
How does MBRS2045CT compare to MBRS2060CT in terms of forward voltage?
MBRS2045CT has a lower typical forward voltage: 0.65V max at 10A/25°C versus 0.80V max for MBRS2060CT. This 0.15V difference reduces conduction loss by ~23% at 10A, making MBRS2045CT preferable in 12V–24V output applications where efficiency and thermal management are critical.
