Product details
Overview
MBRS2535CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 35 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, enabling high-efficiency power conversion in compact SMPS designs.
For engineers reviewing the MBRS2535CT datasheet, MBRS2535CT pinout, MBRS2535CT application, or MBRS2535CT equivalent, key selection criteria include its dual-common-cathode configuration, 1.0 °C/W junction-to-case thermal resistance, J-STD-020 Level 1 moisture sensitivity, and compatibility with automated SMT placement in high-density DC/DC converter layouts.
Technical Context
The MBRS2535CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, supporting synchronous rectification or dual-output configurations. Its guard ring structure provides overvoltage protection, while the matte tin-plated leads ensure reliable solderability per J-STD-002.
Designed for high-frequency switching applications, the device exhibits low reverse recovery charge (inherent to Schottky architecture), 10,000 V/μs critical dv/dt rating, and stable reverse leakage (<200 µA at 25°C, <15 mA at 125°C), enabling robust operation in 20 kHz–1 MHz DC/DC converters without snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (AV) | 25 A - supports continuous output current in 100–300 W SMPS without forced air cooling |
| VRRM | 35 V - defines maximum blocking voltage across each diode in reverse bias |
| VF @ 12.5A, 25°C | 0.65 V max - reduces conduction loss by ~40% vs. comparable PN rectifiers |
| IFSM (8.3 ms) | 200 A - withstands inrush surges during cold-start of AC/DC adapters |
| RθJC | 1.0 °C/W - enables direct heatsinking to PCB copper pour for thermal management |
| TJ max | +150 °C - allows operation in enclosed industrial power supplies with ambient up to +85 °C |
| IR @ VRRM, 25°C | 200 µA max - minimizes standby power loss in energy-efficient adapters |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, 3-terminal configuration with exposed anode tab (Pin 1), common cathode (Pin 2), and second anode (Pin 3). Molding compound meets UL 94V-0; polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |

| Pin 3 (Anode 2) | Second diode anode | Connects to input rail or transformer secondary leg 2; independent conduction path from Pin 1 |
Key Features
| Feature | Design Value |
|---|---|

| Low VF at high IF and TJ | 0.73 V max at 25 A, 125°C - maintains efficiency during thermal stress in sealed enclosures |
| J-STD-020 Level 1 moisture sensitivity | Enables standard reflow without baking, reducing manufacturing cost and cycle time |
| Dual-die common-cathode topology | Reduces component count vs. discrete diodes in dual-output or center-tapped rectification |

Applications
| Switching Mode Power Supply (SMPS) | AC/DC Adapters |
|---|---|
Use Scenario: Primary-side synchronous rectification in 12 V/24 V offline SMPS with 100–250 W output.

IC Role / Device Role / Timing Role: Common-cathode dual diode providing redundancy and thermal sharing across parallel outputs. Use Value: 200 A surge rating handles 5× inrush current during plug-in events without degradation. |
| DC/DC Converters | Industrial Motor Drives |

IC Role / Device Role / Timing Role: Bidirectional clamp diode absorbing inductive kickback from MOSFET switching. Use Value: 150°C max junction temperature ensures uninterrupted operation during sustained 85°C ambient conditions. |
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-MBR2535CT | Identical 25 A / 35 V rating, same TO-263AB package, but RθJC = 1.2 °C/W (vs. 1.0 °C/W for MBRS2535CT) | Slightly higher thermal resistance may require larger copper pour in thermally constrained layouts | Preferred where Vishay supply chain alignment is required; verify layout thermal margin |
| ON Semiconductor MBR2535CT | Same electrical specs and package, but moisture sensitivity level is J-STD-020 Level 2a (requires baking before reflow) | Additional process step needed for humidity-sensitive assembly lines | Valid alternative if baking infrastructure exists; otherwise MBRS2535CT offers lower process overhead |
Compared with VS-MBR2535CT and MBR2535CT, the MBRS2535CT provides superior thermal performance (1.0 °C/W vs. 1.2 °C/W) and eliminates pre-reflow baking (Level 1 vs. Level 2a), reducing manufacturing complexity and improving yield in high-volume adapter production.

FAQ
What is the pin configuration of the MBRS2535CT?
The MBRS2535CT uses a 3-pin TO-263AB (D2PAK) package with Pin 1 as Anode 1, Pin 2 as the common cathode, and Pin 3 as Anode 2. The exposed metal tab is electrically connected to Pin 2 (cathode) and serves as the primary thermal conduction path to the PCB. Polarity is marked on the top surface per the manufacturer's marking diagram.
Does the MBRS2535CT support automated SMT placement?
Yes, the MBRS2535CT is qualified for automated surface-mount placement per its mechanical design and J-STD-020 Level 1 moisture sensitivity rating. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the TO-263AB outline is compatible with standard pick-and-place nozzles and reflow profiles used in high-volume adapter manufacturing.
What is the maximum junction temperature for the MBRS2535CT?
The MBRS2535CT has a maximum junction temperature (TJ max) of +150°C, as specified in the Absolute Maximum Ratings table. This rating applies under steady-state conditions with proper PCB thermal design-specifically, a minimum 10 cm² of 2-oz copper connected to the cathode tab-to maintain junction temperature within limits at full 25 A load.
How does the forward voltage of the MBRS2535CT vary with temperature?
The MBRS2535CT forward voltage decreases with rising junction temperature: at 12.5 A, VF is 0.65 V max at 25°C but drops to 0.55 V max at 125°C. This negative temperature coefficient improves thermal stability in parallel diode configurations and reduces conduction loss during elevated ambient operation.
Is the MBRS2535CT halogen-free and RoHS-compliant?
Yes, the MBRS2535CT is both halogen-free per IEC 61249-2-21 and RoHS-compliant per EU Directive 2011/65/EU. These compliance statements are confirmed in the official Taiwan Semiconductor datasheet revision N2103 and apply to all units shipped under this part number.
