Taiwan Semiconductor Corporation MBRF2035CTH

Overview

MBRF2035CTH from Taiwan Semiconductor is a dual-die AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package, rated for 20A average forward current, 35V repetitive peak reverse voltage, and 150A non-repetitive surge current; it delivers low forward voltage (0.84V at 20A/25°C) and operates up to 150°C junction temperature, enabling high-efficiency power conversion in automotive-grade SMPS and DC-DC converters.

For engineers reviewing the MBRF2035CTH datasheet, MBRF2035CTH pinout, MBRF2035CTH application, or MBRF2035CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1.5°C/W junction-to-case thermal resistance, guard ring–enhanced overvoltage protection, matte tin-plated leads compliant with J-STD-002, and UL Recognition File #E-326243 - all critical for under-hood automotive power designs requiring reliability and thermal robustness.

Technical Context

This dual-common-cathode Schottky rectifier integrates two independent diode dies in a single ITO-220AB thermally optimized package, supporting synchronous rectification and dual-output topologies. Its 10,000 V/µs critical dv/dt rating ensures stable operation during fast-switching transients in high-frequency converters.

The device's low VF (0.72V at 20A/125°C) and low IR (100 µA at 25°C, 15 mA at 125°C) directly reduce conduction losses and leakage-related thermal stress. Its 1.5°C/W R_θJC enables effective heat transfer to heatsinks without forced airflow in space-constrained automotive modules.

FAQ

What does the "H" suffix in MBRF2035CTH signify?

The "H" suffix in MBRF2035CTH explicitly denotes AEC-Q101 qualification, confirming that the device has passed the full stress test suite for automotive discrete semiconductors-including temperature cycling, humidity bias HAST, and ESD testing. This distinguishes MBRF2035CTH from the non-automotive MBRF2035CT variant and validates its suitability for under-hood and chassis-mounted power systems. All MBRF2035CTH units undergo lot-level AEC-Q101 documentation and traceability.

Is MBRF2035CTH pin-compatible with MBRF2035CT?

Yes, MBRF2035CTH is mechanically and electrically pin-compatible with MBRF2035CT - both use identical ITO-220AB packaging, dual-anode/common-cathode pinout, and share identical absolute maximum ratings and electrical specifications. The only functional difference is AEC-Q101 qualification and associated process controls; no PCB redesign or layout change is needed when upgrading from MBRF2035CT to MBRF2035CTH in automotive programs.

What is the thermal performance of MBRF2035CTH at 125°C junction temperature?

At TJ = 125°C, MBRF2035CTH maintains VF = 0.72 V @ 20A and IR = 15 mA @ 35V, enabling reliable operation in high-ambient environments. Its 1.5°C/W R_θJC allows direct mounting to aluminum heatsinks with thermal interface material, achieving ≤85°C case temperature at full 20A load with 20°C ΔT - critical for sustained operation in engine bay or enclosed telecom chassis.

Does MBRF2035CTH meet UL and RoHS requirements?

Yes, MBRF2035CTH is UL Recognized under File #E-326243 and fully RoHS compliant per EU Directive 2011/65/EU. It also meets halogen-free requirements per IEC 61249-2-21, with bromine and chlorine content <900 ppm each. These certifications are documented in TSC's official compliance reports and apply to all production lots shipped with the "H" suffix.

Can MBRF2035CTH be used in parallel configurations?

MBRF2035CTH supports parallel operation when matched for VF and thermal mounting - its dual-die construction and tight VF distribution (±5% typical) enable balanced current sharing. However, external ballasting resistors or current-sharing inductors are recommended for >2 devices in parallel to mitigate thermal runaway risk. Derating to 18A per device is advised for long-term reliability in parallel arrays.
