Taiwan Semiconductor Corporation MBRF2060CT-Y

Overview

MBRF2060CT-Y from Taiwan Semiconductor is a 20A, 60V dual-die Schottky barrier rectifier in ITO-220AB package, featuring low forward voltage (0.80 V at 10 A, 25°C), high surge capability (150 A IFSM), and guard ring overvoltage protection-used in high-efficiency DC/DC converters and SMPS secondary-side rectification.

For engineers reviewing the MBRF2060CT-Y datasheet, MBRF2060CT-Y pinout, MBRF2060CT-Y application, or MBRF2060CT-Y equivalent, key selection criteria include repetitive peak reverse voltage (60 V), thermal resistance (1.5 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power designs.

Technical Context

This dual-common-cathode Schottky rectifier integrates two independent 20A diodes sharing one cathode terminal, enabling synchronous or interleaved output configurations. Its low VF and fast recovery support high-frequency switching (>20 kHz) with minimal conduction loss and reduced thermal stress.

The ITO-220AB package provides direct heatsink mounting via the metal tab (cathode-connected), with 0.56 N·m max torque and UL 94V-0 molding compound. Junction-to-case thermal resistance is 1.5 °C/W, verified under rated 20A DC load conditions.

FAQ

What is the maximum junction temperature rating for MBRF2060CT-Y?

The MBRF2060CT-Y has a maximum junction temperature (T_J) 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 rectifiers. Derating curves confirm 20A average current is sustainable up to 100°C case temperature when mounted on a heatsink with ≤1.5°C/W system thermal resistance. The MBRF2060CT-Y's thermal performance is consistent with its ITO-220AB package construction and internal die attach methodology.

Is MBRF2060CT-Y pin-compatible with MBRF2045CT-Y or MBRF20100CT-Y?

Yes, MBRF2060CT-Y is mechanically and electrically pin-compatible with other members of the MBRF20xCT-Y family-including MBRF2045CT-Y and MBRF20100CT-Y-sharing identical ITO-220AB package, pinout (dual anode + common cathode), and mounting footprint. Voltage rating differences (45V/60V/100V) do not affect physical compatibility, allowing drop-in replacement during design iteration or voltage-scaling upgrades. The MBRF2060CT-Y retains the same marking format, thermal specs, and surge rating across the series, simplifying inventory and layout reuse.

What is the forward voltage specification for MBRF2060CT-Y at elevated temperature?

At 10A and 125°C junction temperature, the MBRF2060CT-Y exhibits a typical forward voltage (V_F) of 0.70 V-measured under pulsed conditions (PW = 0.3 ms). This represents a 0.10 V increase over its 25°C value (0.80 V), reflecting predictable positive temperature coefficient behavior. The MBRF2060CT-Y's low V_F drift ensures stable efficiency in thermally stressed applications like sealed adapters or high-density server bricks, where junction temperatures routinely exceed 100°C during sustained load.

Does MBRF2060CT-Y meet halogen-free and RoHS requirements?

Yes, MBRF2060CT-Y complies with both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The molding compound contains no brominated or chlorinated flame retardants, and all terminations use matte tin plating compliant with J-STD-002 solderability standards. These certifications are documented in TSC's official product change notices and material declarations-making the MBRF2060CT-Y suitable for environmentally regulated end equipment including EU medical peripherals and Japanese industrial controllers.

How is the common cathode terminal implemented in MBRF2060CT-Y?

The common cathode terminal in MBRF2060CT-Y is electrically and thermally connected to the exposed metal tab of the ITO-220AB package, which serves as Pin 3. Internally, both Schottky die cathodes are bonded to this shared tab, enabling low-inductance, low-resistance output return. This construction allows direct mechanical mounting to a heatsink that also functions as the circuit ground or output reference plane-critical for minimizing EMI in high-frequency SMPS. The MBRF2060CT-Y's tab polarity is marked on the device body and must be isolated from chassis ground unless explicitly referenced in the schematic.
