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. at 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, thermal resistance of 2°C/W (junction-to-case), moisture sensitivity level 1 compliance, and suitability for space-constrained DC-DC converters requiring fast switching and minimal conduction loss.
Technical Context
The MBRS1035CT integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection, optimized for synchronous rectification and dual-output DC-DC topologies. Its guard ring structure provides overvoltage protection, and the device supports high dv/dt capability (10,000 V/μs) to withstand rapid voltage transients.
Rated for continuous operation from –55°C to +150°C, the MBRS1035CT maintains stable reverse leakage (<100 µA at 25°C, <15 mA at 100°C) and low forward voltage across temperature-0.67V max at 10A and 125°C-ensuring predictable performance in thermally demanding adapter and industrial power supply environments.

FAQ
What is the pin configuration of the MBRS1035CT?
The MBRS1035CT uses a 3-pin TO-263AB (D2PAK) package with Pin 1 as Anode 1, Pin 2 as the common cathode, and Pin 3 as Anode 2. This dual-anode, single-cathode arrangement supports independent input paths sharing one output node-ideal for center-tapped transformer or dual-winding DC-DC topologies. The exposed thermal pad beneath the package is electrically connected to the cathode (Pin 2).
Does the MBRS1035CT support surface-mount reflow assembly without moisture baking?
Yes, the MBRS1035CT is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without pre-bake. This eliminates process steps and reduces risk of popcorning during assembly-critical for high-throughput manufacturing of power adapters and industrial modules.
What is the maximum junction temperature and how does it affect thermal design for the MBRS1035CT?
The MBRS1035CT has a maximum junction temperature (TJ max) of +150°C. With a junction-to-case thermal resistance of 2°C/W, maintaining TJ ≤150°C requires limiting power dissipation to ≤75W under worst-case ambient and heatsinking conditions. In practice, at 10A and 0.70V VF, conduction loss is ~7W-so a 10°C/W system-level thermal path (including PCB copper and enclosure) keeps TJ safely below 100°C in most applications.
How does the MBRS1035CT compare to standard PN-junction rectifiers in terms of efficiency?
The MBRS1035CT achieves significantly higher efficiency than PN rectifiers due to its Schottky architecture: zero reverse recovery charge (Qrr ≈ 0) eliminates switching loss, and its 0.70V typical forward voltage at 5A is ~0.4V lower than equivalent 10A PN diodes. This reduces conduction loss by ~57% and eliminates associated EMI from recovery spikes-making the MBRS1035CT essential for high-frequency, high-efficiency SMPS designs targeting >90% efficiency.
Is the MBRS1035CT halogen-free and RoHS compliant?
Yes, the MBRS1035CT is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating per J-STD-002. These attributes meet global environmental regulations for consumer, industrial, and automotive electronics-ensuring unrestricted market access and simplified compliance documentation for end-product certifications.
