Product details
Overview
MBRS1035CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 10 A average forward current, 35 V repetitive peak reverse voltage, and 120 A non-repetitive surge current; it delivers low forward voltage (0.70 V typ. at 5 A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency DC/DC conversion in automotive lighting systems.
For engineers reviewing the MBRS1035CTH datasheet, MBRS1035CTH pinout, MBRS1035CTH application, or MBRS1035CTH equivalent, key selection criteria include its AEC-Q101 qualification, 2°C/W junction-to-case thermal resistance, guard ring–enabled overvoltage protection, and suitability for reverse battery protection and freewheeling roles in space-constrained, thermally demanding automotive power stages.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent die in a single TO-263AB surface-mount package, sharing one cathode terminal and featuring separate anodes-enabling synchronous or independent half-wave operation. Its low VF and high IFSM support high-frequency switching topologies with minimal conduction loss and robust transient handling.
The device uses a guard ring structure to enhance ruggedness against voltage transients, and its J-STD-020 Level 1 moisture sensitivity rating allows direct reflow without baking. Thermal performance is defined by RθJC = 2°C/W, supporting high-power density designs when mounted on adequately sized copper planes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 10 A - Sustains continuous output current in DC/DC converters without derating below 100°C case temperature |
| VRRM | 35 V - Withstands peak reverse voltage in 12 V automotive systems with margin for load dump transients |
| VF @ 5A, 25°C | 0.70 V max - Reduces conduction loss to ≤3.5 W per diode, critical for thermal management in sealed modules |
| IFSM (8.3 ms) | 120 A - Survives cold-crank and jump-start surge events in vehicle power networks |
| TJ max | +150 °C - Enables operation in under-hood environments where ambient exceeds 105 °C |
| RθJC | 2 °C/W - Allows direct thermal path to heatsink or PCB copper, limiting junction rise to 20 °C at 10 W dissipation |
| IR @ 35 V, 25°C | 100 µA max - Minimizes leakage-induced standby power loss in always-on vehicle subsystems |
Pinout & Package
TO-263AB (D2PAK) package with three terminals: Anode 1, Anode 2, and common Cathode. Molded epoxy body meets UL 94V-0; matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Accepts positive input for first rectification path; electrically isolated from A2 |
| A2 | Anode of Diode 2 | Accepts positive input for second independent or paralleled rectification path |
| K | Common Cathode | Single low-impedance return node for both diodes; must be routed with minimum inductance to ground/power rail |
Key Features

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-M3/4W | Same TO-263AB package, 10 A/35 V rating, but VF = 0.72 V max at 5 A (25°C); no AEC-Q101 documentation publicly available | Not validated for automotive qualification; suitable for industrial DC/DC where qualification is not mandated | Select when AEC-Q101 is not required and Vishay supply chain preference applies |
| ON Semiconductor MBR1035CT | Identical electrical ratings and TO-263AB package; VF = 0.71 V max at 5 A (25°C); AEC-Q101 qualified per datasheet Rev. 4 (2022) | Direct functional match with same automotive qualification level and thermal specs | Preferred alternative if dual-source assurance is needed for long-life automotive programs |
Compared with MBRS1035CTH, the ON Semiconductor MBR1035CT offers identical qualification and performance with documented AEC-Q101 compliance, while the Vishay part provides comparable electrical behavior without formal automotive validation-making the former ideal for safety-critical platforms and the latter appropriate for cost-sensitive industrial use.

FAQ
What is the maximum junction temperature rating for MBRS1035CTH?
The MBRS1035CTH has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device's 2°C/W junction-to-case thermal resistance supports effective heat transfer when mounted on thermally enhanced PCBs or heatsinks. MBRS1035CTH must be operated within this limit to maintain AEC-Q101 reliability and avoid parametric drift or premature failure.
Is MBRS1035CTH qualified to AEC-Q101 standards?
Yes, MBRS1035CTH is explicitly AEC-Q101 qualified, as confirmed in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version A2103). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), ensuring suitability for automotive power applications. MBRS1035CTH is not just compliant with general automotive requirements-it is certified to the full AEC-Q101 stress test plan, making it appropriate for safety-critical vehicle subsystems.
What does the "CTH" suffix indicate in MBRS1035CTH?
The "CTH" suffix in MBRS1035CTH denotes the TO-263AB (D2PAK) package variant with matte tin-plated leads and green molding compound, per Taiwan Semiconductor's ordering nomenclature. It distinguishes this surface-mount version from through-hole alternatives (e.g., "CT" variants) and confirms compliance with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. MBRS1035CTH is supplied in tape-and-reel packaging (800 units per reel), optimized for automated placement.
How does the guard ring feature improve MBRS1035CTH reliability?
The guard ring in MBRS1035CTH is a diffusion-based structural enhancement that suppresses edge breakdown during high dv/dt transients, allowing the device to sustain 10,000 V/µs without avalanche triggering. This improves robustness against load dump and inductive switching spikes in automotive circuits. MBRS1035CTH's guard ring directly contributes to its ability to operate reliably in freewheeling and reverse battery protection roles where voltage overshoot is common-without requiring external snubbers or derating.
What is the forward voltage drop of MBRS1035CTH at 10 A and 125°C?
At 10 A forward current and 125°C junction temperature, MBRS1035CTH exhibits a maximum forward voltage drop (VF) of 0.67 V, per the "ELECTRICAL SPECIFICATIONS" table in the official datasheet. This low, temperature-stable VF-lower than typical silicon diodes-reduces conduction losses by over 40% compared to standard PN rectifiers under the same conditions. MBRS1035CTH maintains this performance across its full operating temperature range, supporting high-efficiency thermal design in sealed automotive enclosures.
