Product details
Overview
MBR1035H from Taiwan Semiconductor is a 10A, 35V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.70 V max forward voltage at 10A/25°C, 150 A surge current capability, and guard ring overvoltage protection. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the MBR1035H datasheet, MBR1035H pinout, MBR1035H application, or MBR1035H equivalent, key selection criteria include its AEC-Q101 qualification, low VF at high IF, TJ max of 150°C, RθJC of 3°C/W, and TO-220AC thermal mounting compatibility.
Technical Context
This single-die Schottky rectifier uses platinum-silicide or similar low-barrier metallization to achieve fast recovery (no reverse recovery charge), minimal switching loss, and operation up to 150°C junction temperature. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive load-dump conditions.
The device operates with 24 V RMS reverse voltage rating and supports 10,000 V/µs dV/dt, enabling stable performance in high-frequency switching topologies like synchronous buck and flyback converters where low conduction loss is critical.
Key Specifications

| VRRM | 35 V - Maximum repetitive reverse voltage; sets minimum input-to-output differential for safe blocking |
| VF @ 10A, 25°C | ≤ 0.70 V - Directly reduces conduction loss and heat generation in high-current paths |
| IFSM (8.3 ms) | 150 A - Withstands inrush and fault currents without bond-wire fusing |
| RθJC | 3 °C/W - Enables effective heatsinking via TO-220AC tab mounting for thermal management |
| TJ max | +150 °C - Supports under-hood automotive environments and sealed industrial enclosures |
| IR @ 35V, 25°C | ≤ 100 µA - Low leakage preserves efficiency in standby and light-load operation |

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 dual common-cathode configuration; VF = 0.72 V @ 10 A; no AEC-Q101 qualification | Designed for dual-output or interleaved converters; not automotive-qualified | Select when dual-diode topology is required and AEC-Q101 is unnecessary |
| ON Semiconductor MBR1035CT | TO-220AB package; VF = 0.75 V @ 10 A; AEC-Q101 available only in M1 suffix variants | Limited automotive validation scope; different thermal pad isolation design | Choose only if legacy ON Semi BOM alignment is mandatory and AEC-Q101 compliance is verified per batch |
Compared with VS-MBR1035CT and MBR1035CT, the MBR1035H provides guaranteed AEC-Q101 qualification, lower VF, and TO-220AC's superior thermal interface-making it preferred for new automotive designs requiring single-diode, high-reliability rectification.

FAQ
What is the maximum junction temperature rating for the MBR1035H?
The MBR1035H has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 100°C. Thermal design must maintain TJ ≤ 150°C using the specified RθJC of 3°C/W and appropriate heatsinking.
Is the MBR1035H pin-compatible with non-AEC-Q101 versions like MBR1035?
Yes, the MBR1035H shares identical TO-220AC mechanical dimensions, pinout, and electrical specifications with the standard MBR1035. The "H" suffix denotes AEC-Q101 qualification only-no changes to footprint, terminal assignment, or rated parameters. PCB layout and thermal interface design remain fully interchangeable.
What does the guard ring feature provide for the MBR1035H?
The guard ring in the MBR1035H improves edge termination robustness, preventing premature avalanche breakdown during voltage transients such as automotive load dump (ISO 7637-2 Pulse 5a). It enhances long-term reliability in systems exposed to repetitive overvoltage stress without increasing forward voltage or leakage current.
How does the MBR1035H's forward voltage compare at elevated temperature?
At 10 A and TJ = 125°C, the MBR1035H exhibits a typical forward voltage of 0.57 V-lower than its 25°C value of ≤0.70 V. This negative temperature coefficient is characteristic of Schottky diodes and improves thermal stability in high-power applications, reducing risk of thermal runaway during sustained high-current operation.
Can the MBR1035H be used in surface-mount designs?
No, the MBR1035H is exclusively offered in the through-hole TO-220AC package with a metal tab for heatsinking. It is not available in surface-mount variants such as D²PAK or TO-263. For SMT-compatible alternatives, engineers should evaluate TSC's MBR20xxL series or consult Aetrix for qualified drop-in replacements with equivalent ratings.
