Product details
Overview
MBRS1035CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 10A average forward current, 35V repetitive peak reverse voltage, and 120A non-repetitive surge current; it delivers low forward voltage (0.70V typ. @ 5A, 25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in compact SMPS designs.
For engineers reviewing the MBRS1035CT datasheet, MBRS1035CT pinout, MBRS1035CT application, or MBRS1035CT equivalent, key selection criteria include its dual-common-cathode configuration, 2°C/W junction-to-case thermal resistance, J-STD-020 Level 1 moisture sensitivity, and compatibility with automated SMT placement in high-density DC/DC converter layouts.
Technical Context
This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, supporting synchronous rectification or dual-output configurations. Its guard ring structure enhances ruggedness against transient overvoltage events, while the matte tin-plated terminals ensure reliable solderability per J-STD-002.
The MBRS1035CT exhibits low reverse recovery charge and negligible minority-carrier storage, eliminating switching tail current. With 10,000 V/μs critical dv/dt rating and 100 µA max reverse leakage at 25°C, it maintains stable operation under fast-rising edge conditions typical in high-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (AV) | 10 A - supports continuous output current in 50–100W adapter and DC/DC converter designs |
| VRRM | 35 V - defines maximum blocking capability in low-voltage secondary-side rectification |
| VF (typ, 5A, 25°C) | 0.70 V - reduces conduction loss by ~30% vs. comparable silicon diodes, improving efficiency |
| IFSM (8.3ms) | 120 A - withstands inrush surges during cold-start or load-step transients |

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-10BQ030TRPBF | Single-diode TO-263AB, 10A/30V, VF = 0.52V @ 10A - lower VRRM, lower VF, no dual-anode configuration | Requires two devices for dual-output use; better suited for single-rail, ultra-low-VF designs | Select when lowest possible conduction loss is prioritized over circuit integration |
| ON Semiconductor MBR1035CT | Same dual-common-cathode TO-263AB, identical 10A/35V rating, VF = 0.72V @ 5A - minor process variation, same pinout and footprint | Drop-in replacement with identical thermal and electrical behavior in existing layouts | Preferred for second-source assurance where Taiwan Semiconductor supply continuity is constrained |
Compared with VS-10BQ030TRPBF and MBR1035CT, the MBRS1035CT offers integrated dual-anode functionality with industry-standard 35V blocking and proven thermal performance (2°C/W RθJC), making it optimal for space-constrained dual-output converters where layout consolidation matters more than marginal VF reduction.

FAQ
What is the pin configuration of the MBRS1035CT?
The MBRS1035CT uses a 3-pin TO-263AB (D2PAK) package with Anode 1, Anode 2, and a shared Cathode terminal. The cathode is electrically common to both diodes, enabling dual-output or interleaved rectification without external wiring. Pin 1 (left) is A1, Pin 2 (center) is K, and Pin 3 (right) is A2 - confirmed by TSC's official marking diagram and mechanical drawings.
Does the MBRS1035CT support automated SMT placement?
Yes, the MBRS1035CT is qualified for automated surface-mount placement per its J-STD-020 Level 1 moisture sensitivity rating and matte tin-plated leads compliant with J-STD-002 solderability standards. Its TO-263AB outline and symmetric thermal pad allow reliable pick-and-place and reflow profiling without tombstoning or voiding concerns.
What is the maximum junction temperature for continuous operation of the MBRS1035CT?
The MBRS1035CT has a maximum rated junction temperature of +150°C, verified across its full operating range per TSC's Absolute Maximum Ratings table. This allows uninterrupted operation in sealed enclosures or high-ambient environments when paired with appropriate PCB copper area or external heatsinking per its 2°C/W RθJC specification.
How does the guard ring feature improve reliability of the MBRS1035CT?
The guard ring in the MBRS1035CT provides edge termination that redistributes electric field stress away from the active junction periphery. This increases the device's ability to withstand transient overvoltage events - such as ESD or inductive kickback - without avalanche breakdown, extending lifetime in noisy industrial power systems where line transients exceed 50V.
Is the MBRS1035CT halogen-free and RoHS compliant?
Yes, the MBRS1035CT is certified halogen-free per IEC 61249-2-21 and fully RoHS compliant, as stated in TSC's official documentation. The molding compound contains no brominated flame retardants, and all terminations meet EU Directive 2011/65/EU restrictions on lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE.
