Product details
Overview
MBRB10H35-E3/45 from Vishay General Semiconductor is a Schottky barrier rectifier in TO-263AB package, rated for 10 A average forward current, 35 V repetitive peak reverse voltage, and 150 A surge capability. It features low forward voltage (0.55 V at 10 A, 25 °C), low leakage (100 µA at 35 V, 25 °C), and high-temperature operation up to 175 °C junction temperature - used in DC-DC converter output rectification and freewheeling paths.
For engineers reviewing the MBRB10H35-E3/45 datasheet, MBRB10H35-E3/45 pinout, MBRB10H35-E3/45 application, or MBRB10H35-E3/45 equivalent, key selection criteria include thermal resistance (RθJC = 2.0 °C/W), guardring-enabled overvoltage protection, RoHS compliance, and J-STD-020 MSL Level 1 rating for surface-mount reflow compatibility.
Technical Context
This device uses high-barrier Schottky technology to reduce reverse leakage at elevated temperatures while maintaining low VF - critical for efficiency in high-frequency switching power supplies. Its guardring structure provides robust transient overvoltage immunity without external snubbers.
The TO-263AB package enables high-power surface-mount operation with direct heatsink attachment via the exposed cathode pad (Pin 2). Thermal resistance of 2.0 °C/W from junction-to-case supports sustained 10 A conduction at ≤125 °C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 10 A - supports continuous output rectification in 5–12 V DC-DC converters without forced air cooling |
| VRRM | 35 V - suitable for 24 V nominal input systems with margin against line transients |
| VF @ 10 A, 25 °C | 0.55 V - reduces conduction loss to ~5.5 W per diode, improving system efficiency vs. standard silicon rectifiers |
| IR @ 35 V, 25 °C | 100 µA - minimizes standby power loss in battery-backed or energy-sensitive applications |
| RθJC | 2.0 °C/W - allows direct PCB copper pour heatsinking to maintain TJ < 175 °C at full load |
| TJ max. | 175 °C - enables operation in under-hood automotive or industrial ambient environments |
| IFSM (8.3 ms) | 150 A - withstands inrush currents during cold-start or short-circuit recovery in SMPS |
Pinout & Package
TO-263AB (D2PAK) surface-mount package with isolated anode (Pin 1) and electrically exposed cathode tab (Pin 2/K). Cathode tab serves as both electrical terminal and thermal interface to PCB heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to switching node or transformer secondary |
| Pin 2 / K | Cathode / Heatsink Pad | Output terminal and primary thermal path; must be soldered to ≥200 mm² copper area for RθJC spec |
Key Features
| Feature | Design Value |
|---|---|
| Guardring structure | Enables self-protected operation against 100 V transients without external clamping components |
| Low VF at high temperature | 0.61 V at 10 A, 125 °C - maintains efficiency in thermally constrained enclosures |
| MSL Level 1 rating | Compatible with standard 245 °C peak reflow profiles (J-STD-020), no baking required pre-assembly |
| RoHS & WEEE compliant | Lead-free matte tin plating meets J-STD-002 solderability and environmental directives |
| High surge rating | 150 A IFSM supports >100,000 cycles in motor drive freewheeling applications |
Applications
| DC-DC Converter Output Rectification | Automotive Body Control Module Power Supply |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1035CB | Same TO-263AB package, 10 A/35 V, but VF = 0.57 V (10 A, 25 °C); RθJC = 2.5 °C/W | Slightly higher conduction loss and thermal resistance limit continuous 10 A use without enhanced PCB heatsinking | Acceptable where board-level thermal design accommodates +0.5 W extra loss and +10 °C junction rise |
| ON Semi MBR1035CT | TO-220AC package, dual common-cathode die; VF = 0.54 V (10 A, 25 °C), RθJC = 2.0 °C/W per diode | Through-hole mounting only; requires heatsink hardware and increases assembly cost vs. surface-mount MBRB10H35-E3/45 | Preferred only when legacy through-hole assembly or dual-diode configuration is mandatory |
Compared with STPS1035CB and MBR1035CT, the MBRB10H35-E3/45 delivers identical voltage rating and superior thermal performance in a surface-mount footprint - enabling higher power density and eliminating mechanical heatsink hardware in space-constrained 12 V systems.

FAQ
What is the maximum junction temperature rating for MBRB10H35-E3/45?
The MBRB10H35-E3/45 has a maximum junction temperature (TJ) of +175 °C, verified per datasheet Document Number 88780. This rating enables reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 100 °C. The device maintains specified VF and IR performance up to this limit when thermal design respects the 2.0 °C/W RθJC specification.
Is MBRB10H35-E3/45 RoHS compliant and lead-free?
Yes, MBRB10H35-E3/45 is RoHS 2002/95/EC and WEEE 2002/96/EC compliant. Its matte tin-plated leads meet J-STD-002 solderability requirements and JESD22-B102 for lead-free assembly. The "E3" suffix confirms consumer-grade qualification including JESD201 Class 1A whisker testing - no lead content is present in the finish or internal construction.
What does the "/45" suffix mean in MBRB10H35-E3/45?
The "/45" in MBRB10H35-E3/45 is Vishay's package code indicating tube packaging with 50 units per tube. It is not a performance variant or temperature grade identifier. The electrical and thermal specifications remain identical to other MBRB10H35-E3 variants - only the delivery format differs. Reel-packaged versions use "/81" (800/reel).
Can MBRB10H35-E3/45 replace MBR10H35-E3 in existing designs?
MBRB10H35-E3/45 is not a direct drop-in replacement for through-hole MBR10H35-E3 due to its TO-263AB surface-mount footprint and single-anode/single-cathode configuration. While electrical specs match, PCB layout must be revised to accommodate the D2PAK outline and thermal pad. No pin-to-pin compatibility exists between TO-220AC and TO-263AB packages.
What is the thermal resistance from junction to case (RθJC) for MBRB10H35-E3/45?
The junction-to-case thermal resistance (RθJC) of MBRB10H35-E3/45 is 2.0 °C/W, measured from the silicon die to the cathode metal tab (Pin 2/K) under standard test conditions. This value assumes full-solder coverage of the exposed cathode pad to ≥200 mm² of 2 oz copper - achieving it requires proper stencil design and reflow profile control per J-STD-020.
