Product details
Overview
MBR2035CT-Y from Taiwan Semiconductor is a 20A, 35V dual-die Schottky barrier rectifier in TO-220AB package, featuring 150A surge current capability, 0.84V forward voltage at 20A/25°C, and junction-to-case thermal resistance of 1°C/W. It serves as a high-efficiency output rectifier in switching mode power supplies requiring low conduction loss and fast recovery.
For engineers reviewing the MBR2035CT-Y datasheet, MBR2035CT-Y pinout, MBR2035CT-Y application, or MBR2035CT-Y equivalent, key selection criteria include repetitive peak reverse voltage (35V), forward current rating (20A), thermal resistance (1°C/W), reverse leakage (100µA @ 25°C), and TO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This dual-die Schottky rectifier integrates two independent 35V/20A diodes in a single TO-220AB case with common cathode configuration. Its low VF (0.84V @ 20A/25°C) and absence of minority-carrier storage enable zero-recovery switching behavior critical for high-frequency SMPS topologies.
The device operates across -55°C to +150°C junction temperature range, supports 10,000 V/μs critical dv/dt rating, and meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability requirements - confirming suitability for industrial-grade power conversion under thermal and mechanical stress.

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 35V VRRM, 20A IF, TO-220AC package; VF = 0.72V @ 20A/25°C (lower), RθJC = 1.5°C/W (higher) | Lower conduction loss but requires larger heatsink due to higher thermal resistance | Select when lowest possible VF dominates over thermal interface simplicity |
| ON Semiconductor MBR2035CT | Identical electrical specs and TO-220AB package; lacks "-Y" suffix indicating green/halogen-free compound per IEC 61249-2-21 | Not suitable for RoHS-compliant or halogen-free manufacturing lines requiring certified material declarations | Select only if halogen-free compliance is not required and legacy stock availability is prioritized |

FAQ
What is the maximum junction temperature rating for MBR2035CT-Y?
The MBR2035CT-Y has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from -55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed industrial power supplies or telecom shelves, provided the junction-to-case thermal resistance (1°C/W) is respected in heatsink design. The MBR2035CT-Y must not exceed this limit under steady-state or transient conditions.
Does MBR2035CT-Y support common-cathode dual-diode configuration?
Yes, the MBR2035CT-Y integrates two independent Schottky diodes with a shared cathode connection at the metal tab (Pin 1). Pins 2 and 3 serve as separate anodes, enabling dual-output rectification (e.g., ±12V) or paralleled operation. This configuration is explicitly confirmed in the device marking diagram, mechanical outline, and absolute maximum ratings table for MBR2035CT-Y.
What is the forward voltage drop of MBR2035CT-Y at full rated current?
The MBR2035CT-Y exhibits a maximum forward voltage drop of 0.84 V at 20 A and 25°C junction temperature, as specified in the Electrical Specifications table. At elevated temperature (125°C), VF rises to 0.72 V under the same 20 A condition. These values are measured per diode and reflect actual conduction loss under real-world operating conditions.
Is MBR2035CT-Y halogen-free and RoHS compliant?
Yes, the MBR2035CT-Y is certified halogen-free per IEC 61249-2-21 and RoHS compliant, as stated in the FEATURES section of the official datasheet. The "-Y" suffix explicitly denotes green molding compound meeting these environmental standards, distinguishing it from non-suffixed variants like MBR2035CT that lack halogen-free certification.
What is the surge current rating for MBR2035CT-Y and how is it tested?
The MBR2035CT-Y supports a non-repetitive peak forward surge current (IFSM) of 150 A, tested using an 8.3 ms single half-sine wave superimposed on rated DC load, per JEDEC standards. This rating is validated at TA = 25°C and confirms robustness against inrush currents during power-up or fault transients in SMPS and DC-DC converter applications.
