Product details
Overview
MBRB2535CT from Vishay is a dual common-cathode Schottky rectifier in D2PAK package, rated for 2 × 15 A average forward current per leg, 35 V maximum DC reverse voltage, and operation up to 150 °C junction temperature. It delivers low forward voltage drop (0.73 V at 30 A, 125 °C) and high-frequency switching performance, making it suitable for output rectification in high-efficiency AC/DC and DC/DC power supplies.
For engineers reviewing the MBRB2535CT datasheet, MBRB2535CT pinout, MBRB2535CT application, or MBRB2535CT equivalent, key selection criteria include thermal resistance (1.5 °C/W per leg), reverse leakage (40 mA at 125 °C), junction capacitance (700 pF at 5 V), and ruggedness features including guard ring and Q101 qualification.
Technical Context
This center-tap Schottky rectifier uses proprietary barrier technology to achieve stable low-leakage performance at elevated temperatures. Its dual-anode/common-cathode configuration supports synchronous rectification and freewheeling paths in half-bridge and full-wave topologies.
Designed for high-power density systems, it combines low VF slope resistance (12.3 mΩ), fast dV/dt capability (10,000 V/µs), and robust thermal design with RthJC = 1.5 °C/W per leg - enabling compact heatsink integration in telecom and industrial SMPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 15 A at TC = 130 °C - defines continuous conduction capability per anode under heatsink-limited thermal conditions |
| VRRM | 35 V - maximum allowable DC reverse blocking voltage without breakdown |
| VF at 30 A, 125 °C | 0.73 V - directly determines conduction loss and thermal load in high-current output stages |
| IRM at 125 °C | 40 mA - reverse leakage magnitude impacting standby efficiency and thermal runaway risk |
| RthJC per leg | 1.5 °C/W - quantifies thermal bottleneck from junction to case, critical for heatsink sizing |
| CT at 5 V | 700 pF - influences high-frequency switching losses and EMI behavior in >100 kHz converters |
| dV/dt rating | 10,000 V/µs - enables reliable operation in fast-switching circuits without spurious turn-on |
Pinout & Package
D2PAK (TO-263) surface-mount package with exposed copper pad for thermal enhancement. Molded epoxy body meets moisture resistance and mechanical strength requirements per MIL-STD-750.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First anode terminal | Connects to primary switching node (e.g., transformer secondary or half-bridge leg) |
| 2 (Cathode) | Common cathode | Output node shared by both diodes; connects to +VOUT rail and heatsink plane |
| 3 (Anode B) | Second anode terminal | Connects to complementary switching node (e.g., second transformer winding or alternate leg) |
Key Features
| Feature | Design Value |
|---|---|
| 150 °C TJ operation | Enables use in high-ambient environments (e.g., enclosed industrial power modules) without derating penalties |
| Guard ring structure | Improves edge termination reliability and prevents premature avalanche failure under transient overvoltage |
| Q101 qualification | Validates robustness for automotive-grade power conversion where AEC-Q101 compliance is mandatory |
| Low VF slope resistance | 12.3 mΩ minimizes I²R losses across wide load range, improving full-load efficiency in 12–48 V outputs |
| High-purity epoxy encapsulation | Provides enhanced moisture resistance (MSL 1) and mechanical stability during reflow and thermal cycling |
Applications
| Server PSU Output Rectification | Industrial DC/DC Converter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS3035CG | TO-220AC package, single-diode configuration, 30 A total IF(AV), same 35 V VR | Lacks dual-anode topology; requires two devices for center-tap replacement | Preferred when board layout permits discrete placement and thermal management via TO-220 heatsink |
| ON Semi NTS4101PT1G | Single-channel 30 V MOSFET-based ideal diode controller, not a passive rectifier | Replaces Schottky with active solution offering <10 mV forward drop and programmable current limit | Selected when ultra-low VF and precise fault control outweigh cost and complexity of gate drive circuitry |
Compared with STPS3035CG and NTS4101PT1G, the MBRB2535CT provides integrated dual-anode functionality in a single D2PAK footprint, eliminating interconnect inductance and simplifying PCB layout - critical for high-current, high-density power designs where thermal coupling and layout parasitics dominate efficiency.

FAQ
What is the maximum junction temperature rating for the MBRB2535CT?
The MBRB2535CT is rated for continuous operation up to 150 °C junction temperature, verified per Q101 stress testing. This allows deployment in thermally constrained enclosures such as sealed server PSUs or industrial motor drives without additional derating beyond the specified IF(AV) vs. TC curve. The MBRB2535CT maintains stable VF and IRM characteristics across this full range.
Does the MBRB2535CT have a center-tap configuration?
No - the MBRB2535CT is a dual-anode/common-cathode Schottky rectifier, not a center-tapped device. Its pinout (Anode A – Cathode – Anode B) supports full-wave rectification using external transformer or inverter topology, unlike true center-tap transformers that require three-wire secondary windings. The MBRB2535CT integrates both anodes into one package for compact dual-path conduction.
What is the thermal resistance from junction to case per leg for the MBRB2535CT?
The MBRB2535CT has a maximum thermal resistance of 1.5 °C/W per leg (RthJC) under DC operation. This value is measured from each die junction to the common case (exposed copper pad), and is critical for calculating allowable case temperature in high-power designs. The MBRB2535CT's D2PAK package enables direct thermal coupling to PCB copper or heatsink surfaces.
Is the MBRB2535CT lead-free and RoHS compliant?
Yes - the MBRB2535CT is manufactured with lead-free terminations and complies with EU RoHS Directive 2011/65/EU and China RoHS. Per Vishay documentation, the part marking "MBRB2535CT" indicates standard Pb-free production unless otherwise ordered with suffix "PbF". The MBRB2535CT meets JEDEC J-STD-020 moisture sensitivity level 1.
How does the guard ring feature improve reliability of the MBRB2535CT?
The guard ring in the MBRB2535CT enhances edge termination robustness by controlling electric field distribution at the silicon periphery. This prevents localized avalanche breakdown during voltage transients and improves long-term stability under thermal cycling. In real-world use, the MBRB2535CT demonstrates no parameter drift after 1000 cycles from -40 °C to 150 °C, validating the guard ring's contribution to field reliability.
