Taiwan Semiconductor Corporation MBRS2035CT MNG

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 operates up to 150°C junction temperature and delivers low forward voltage drop (0.65V max at 10A, 25°C), enabling high-efficiency power conversion in compact DC/DC converters.

For engineers reviewing the MBRS2035CT datasheet, MBRS2035CT pinout, MBRS2035CT application, or MBRS2035CT equivalent, key selection criteria include its dual-common-cathode configuration, thermal resistance of 1.5°C/W (junction-to-case), moisture sensitivity level 1 compliance, guard ring–enabled overvoltage protection, and suitability for automated SMT assembly in high-density power supplies.

Technical Context

This device integrates two independent Schottky diodes in a single TO-263AB surface-mount package with common cathode connection. Its low V_F and high I_FSM support efficient high-frequency switching in SMPS topologies where conduction loss minimization and transient robustness are critical.

The dual-die structure enables shared thermal path and simplified layout for center-tapped or synchronous rectification schemes. Guard ring design enhances ruggedness against voltage transients, while JESD201 Class 2 whisker resistance and matte tin plating ensure long-term solder joint reliability under thermal cycling.

FAQ

What is the pin configuration of the MBRS2035CT?

The MBRS2035CT uses a 3-pin TO-263AB (D2PAK) package with Anode 1, Anode 2, and Common Cathode terminals. Pin 1 (left) is Anode 1, Pin 2 (center) is Cathode, and Pin 3 (right) is Anode 2-verified per TSC package outline drawing N2103. This common-cathode arrangement simplifies PCB layout for dual-output or center-tapped transformer designs. The MBRS2035CT pinout supports direct replacement of discrete dual-diode solutions without netlist changes.

Does the MBRS2035CT require a heatsink in typical operation?

The MBRS2035CT achieves 1.5°C/W junction-to-case thermal resistance and is rated for 20A continuous current at 150°C junction temperature. With adequate PCB copper (≥2 in² 2-oz copper pour under the tab), it can operate without an external heatsink in ambient temperatures ≤60°C. For sustained 20A loads above 70°C ambient, a bolted heatsink or thermal interface pad is recommended. Thermal performance data for the MBRS2035CT is validated per JEDEC JESD51-14 standards.

Is the MBRS2035CT suitable for automotive applications?

The MBRS2035CT is not AEC-Q101 qualified and is not recommended for safety-critical automotive functions such as ADAS or powertrain control. However, it is widely used in non-safety automotive applications including infotainment power supplies, body control modules, and LED lighting drivers-provided system-level qualification (e.g., temperature cycling, vibration, and EMC testing) is performed. Taiwan Semiconductor does not specify automotive-grade screening for the MBRS2035CT.

What is the maximum reverse leakage current of the MBRS2035CT at elevated temperature?

At rated 35V reverse voltage and 125°C junction temperature, the MBRS2035CT exhibits a maximum reverse leakage current of 15 mA per diode, as specified in the Electrical Specifications table on page 3 of the N2103 datasheet. This value is measured under pulsed conditions (PW = 30 ms) and reflects worst-case behavior under thermal stress. At 25°C, leakage is limited to 100 µA max, confirming tight process control across the MBRS2035CT production lot.

Can the MBRS2035CT be used in place of the MBRS2045CT?

No-the MBRS2035CT and MBRS2045CT share identical package, pinout, and thermal characteristics but differ in maximum repetitive peak reverse voltage (35V vs. 45V). Substituting MBRS2035CT for MBRS2045CT risks premature breakdown in circuits operating near 40V or subject to >10V transients. The MBRS2035CT is only acceptable where system-level analysis confirms worst-case reverse voltage remains ≤35V with margin. Always verify voltage derating per application before interchange.
