Product details
Overview
MBRS2035CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 20A average forward current, 35V repetitive peak reverse voltage, and 150A surge current. It delivers low forward voltage (0.65V max at 10A/25°C), operates up to 150°C junction temperature, and is used in high-efficiency switching power supplies.
For engineers reviewing the MBRS2035CT datasheet, MBRS2035CT pinout, MBRS2035CT application, or MBRS2035CT equivalent, key selection criteria include thermal resistance (1.5°C/W), guard-ring overvoltage protection, moisture sensitivity level 1 compliance, and dual-diode configuration for center-tapped or full-wave rectification.
Technical Context
This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode configuration (CT suffix). Its low VF and high IFSM support high-frequency switching topologies where conduction loss and thermal management are critical.
The 1.5°C/W junction-to-case thermal resistance enables efficient heat transfer to the PCB copper pour or heatsink, while the guard ring structure enhances ruggedness against transient overvoltage events without external snubbers.
Key Specifications

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-20CPH03-M3 | Same 20A/35V rating, TO-263AB package, but higher typical VF (0.72V @ 10A/25°C); RθJC = 1.7°C/W | Slightly lower efficiency at high load; requires larger copper area for equivalent thermal performance | Acceptable where marginal efficiency loss is tolerable and Vishay supply chain preference applies |
| ON Semiconductor MBR2035CT | Identical electrical specs and TO-263AB package; same 0.65V VF max, 1.5°C/W RθJC, and 150A IFSM | No functional difference; validated in identical reference designs across multiple OEMs | Drop-in alternative with identical board-level behavior and qualification history |
Compared with VS-20CPH03-M3, MBRS2035CT offers lower conduction loss and better thermal dissipation; versus MBR2035CT, it shares identical performance but differs in manufacturing origin and traceability-both remain viable for cost, lead time, or regional sourcing optimization.

FAQ
What is the maximum junction temperature rating for MBRS2035CT?
The MBRS2035CT has a maximum junction temperature (TJmax) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows sustained operation in sealed enclosures or high-ambient environments when thermal design meets the 1.5°C/W junction-to-case resistance specification. Derating curves confirm usable current capacity down to 10A at 125°C case temperature.
Does MBRS2035CT have a common-cathode configuration?
Yes, the "CT" suffix in MBRS2035CT explicitly denotes a common-cathode dual-diode configuration. Pin 2 (the exposed tab) is the shared cathode, while Pins 1 and 3 serve as independent anodes. This layout supports center-tapped transformer rectification and eliminates the need for external cathode tying, reducing parasitic inductance and layout complexity.
What is the forward voltage specification for MBRS2035CT at full rated current?
At 20A and 25°C junction temperature, the MBRS2035CT exhibits a maximum forward voltage (VF) of 0.84V per diode. At elevated temperature (125°C), this increases to 0.72V max-lower than many competing Schottky rectifiers due to optimized metallization and die design.
Is MBRS2035CT suitable for lead-free reflow soldering?
Yes, MBRS2035CT is qualified for lead-free reflow soldering per J-STD-020. Its moisture sensitivity level is rated Level 1, meaning it can be stored indefinitely in dry conditions and placed directly into standard Pb-free reflow profiles (peak 260°C) without baking. Matte tin plating ensures robust solder joint formation per J-STD-002.
What packaging format is offered for MBRS2035CT?
MBRS2035CT is supplied in tape-and-reel packaging: 800 units per reel. The TO-263AB (D2PAK) package is compatible with automated pick-and-place equipment, and the reel conforms to EIA-481 standards. Reel markings include date code (YWW), factory code (F), and green compound indicator (G) per TSC's marking diagram.
