Product details
Overview
MBR1035 from Taiwan Semiconductor is a 10 A, 35 V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.70 V at 10 A, 25°C), high surge current capability (150 A), and junction-to-case thermal resistance of 3°C/W. It serves as a primary output rectifier in high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the MBR1035 datasheet, MBR1035 pinout, MBR1035 application, or MBR1035 equivalent, key selection criteria include forward voltage drop at full load, reverse leakage at elevated temperature, thermal derating behavior, and compatibility with TO-220AC heatsink mounting requirements.
Technical Context
The MBR1035 uses a single-die Schottky structure optimized for low conduction loss in medium-voltage SMPS outputs. Its guard ring design enhances ruggedness against transient overvoltage events, while its 150°C maximum junction temperature supports operation in thermally constrained industrial environments.
Electrical performance is specified across temperature ranges: forward voltage drops to 0.57 V at 10 A and 125°C, and reverse leakage remains ≤100 µA at 25°C and ≤15 mA at 125°C under rated 35 V reverse bias - critical for standby power and thermal stability in compact adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 10 A continuous - supports high-current secondary-side rectification without forced air cooling |
| Peak Reverse Voltage (VRRM) | 35 V - suitable for 24 V nominal output rails with margin for ripple and transients |
| Forward Voltage (VF) | 0.70 V max at 10 A, 25°C - reduces conduction loss vs. silicon diodes, improving efficiency by ~2–3% in 12–24 V DC/DC stages |
| Surge Current (IFSM) | 150 A (8.3 ms half-sine) - withstands inrush and fault currents in unregulated input stages |
| Junction-to-Case Thermal Resistance (RθJC) | 3°C/W - enables direct heatsink mounting for thermal management in space-constrained designs |
| Operating Junction Temperature | −55°C to +150°C - qualified for industrial and automotive under-hood ambient conditions |
| Reverse Leakage (IR) | ≤100 µA at 25°C, ≤15 mA at 125°C - limits standby power loss and ensures reliability at elevated temperatures |
Pinout & Package
Package: TO-220AC - three-terminal, through-hole, single-die rectifier with center-tab cathode, matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to transformer secondary or switch node; must handle full 10 A RMS and 150 A surge |
| Cathode | Output terminal for forward conduction | Center tab - electrically and thermally connected to heatsink; requires insulated mounting if heatsink is grounded |
| Case / Tab | Cathode connection and thermal path | Not isolated; serves as primary heat dissipation interface - mounting torque limited to 0.56 N·m |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Enhances avalanche ruggedness and prevents premature breakdown during line transients in offline SMPS |
| AEC-Q101 qualification option (MBR1035H) | Validated for automotive under-hood applications including engine control modules and infotainment power supplies |
| Low VF at high temperature | 0.57 V at 10 A and 125°C - maintains efficiency in thermally stressed environments where silicon diodes degrade significantly |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets environmental compliance requirements for RoHS-compliant industrial and consumer end equipment |
| High dV/dt rating | 10,000 V/µs - resists false turn-on in fast-switching topologies like synchronous rectification and resonant converters |

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-MBR1035CT | TO-220AB package (dual common-cathode die); VF = 0.72 V @ 10 A, 25°C; IR = 120 µA @ 25°C | Designed for dual-output or parallel configurations; not single-die replacement | Select only when dual-cathode topology is required; requires PCB layout change due to different pinout and thermal pad geometry |
| ON Semiconductor MBR1035CT | TO-220AB package; VF = 0.71 V @ 10 A, 25°C; IR = 100 µA @ 25°C; AEC-Q101 qualified in H suffix version | Same electrical specs but dual-diode configuration; no single-die TO-220AC variant offered | Use only if dual-diode functionality is needed; MBR1035CT cannot substitute MBR1035 in single-diode layouts without redesign |
Compared with VS-MBR1035CT and MBR1035CT, the MBR1035 offers true single-die, single-anode/single-cathode topology in TO-220AC - simplifying thermal design, reducing BOM count, and eliminating cross-conduction risk in single-rail outputs.

FAQ
What is the maximum junction temperature rating for the MBR1035?
The MBR1035 has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version M2103). This allows sustained operation in thermally demanding environments such as enclosed power adapters or industrial DC/DC modules. Derating curves confirm usable current capacity down to 6 A at 125°C case temperature. The MBR1035 must be mounted to an appropriate heatsink to maintain TJ ≤ 150°C under full 10 A load.
Is the MBR1035 RoHS and halogen-free compliant?
Yes, the MBR1035 is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version M2103). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These compliance attributes are confirmed for all standard MBR1035 variants, not limited to the "H" (AEC-Q101) suffix version.
Does the MBR1035 have AEC-Q101 qualification?
The base MBR1035 is not AEC-Q101 qualified; however, the MBR1035H variant is explicitly listed as AEC-Q101 qualified in the ordering information section of the Taiwan Semiconductor datasheet (Version M2103). The "H" suffix denotes automotive-grade screening and testing. Standard MBR1035 parts lack this qualification and should not be used in automotive safety-critical or under-hood applications unless re-qualified by the end customer.
What is the forward voltage drop of the MBR1035 at 10 A and 125°C?
The MBR1035 exhibits a typical forward voltage (VF) of 0.57 V at 10 A and 125°C, as specified in the "ELECTRICAL SPECIFICATIONS" table of the Taiwan Semiconductor datasheet (Version M2103). This value is lower than its 25°C VF (0.70 V max), reflecting the negative temperature coefficient of Schottky diodes. Designers must use this 125°C value for worst-case thermal analysis in high-ambient applications.
What is the reverse leakage current of the MBR1035 at 125°C?
At 125°C and rated 35 V reverse voltage, the MBR1035 has a maximum reverse leakage current (IR) of 15 mA, per the "ELECTRICAL SPECIFICATIONS" table in the Taiwan Semiconductor datasheet (Version M2103). This value is critical for standby power budgeting in energy-efficient adapters and must be accounted for alongside other system leakage paths. At 25°C, IR is limited to 100 µA, demonstrating strong temperature-dependent behavior typical of Schottky structures.
