Diodes Incorporated MBR1060CT-I

Overview

MBR1060CT-I from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 60V peak repetitive reverse voltage, with maximum 0.75V forward voltage at 5A/25°C and 0.1mA reverse leakage at 25°C. It serves as polarity protection, freewheeling, or switching diode in DC power supplies, battery chargers, and industrial SMPS.

For engineers reviewing the MBR1060CT-I datasheet, MBR1060CT-I pinout, MBR1060CT-I application, or MBR1060CT-I equivalent, key selection criteria include per-leg 60V VRRM rating, low VF for thermal efficiency, TO-220AB thermal resistance (3 K/W), AEC-Q101 qualification, and dual-diode configuration enabling compact half-wave or full-wave rectification layouts.

Technical Context

This dual Schottky rectifier integrates two independent 60V/5A diodes sharing a common cathode terminal, enabling synchronous half-wave operation or independent leg use. Its guard ring die construction enhances transient immunity, while the TO-220AB package provides direct heatsink mounting and 3 K/W junction-to-case thermal resistance.

Electrical behavior is characterized by low forward voltage (0.75V max @ 5A/25°C), minimal reverse recovery charge (inherent to Schottky topology), and temperature-stable capacitance (150 pF typical @ 1 MHz/4V). Reverse leakage remains ≤0.1 mA at 25°C and ≤15 mA at 125°C under rated blocking voltage.

FAQ

Is MBR1060CT-I suitable for surface-mount assembly?

No. MBR1060CT-I uses the through-hole TO-220AB package with a metal tab designed for screw-mount heatsinking. It lacks SMD-compatible footprint or reflow profile specifications. For SMT alternatives, consider Diodes' APD1060CTQ or ON Semiconductor's SB1060.

What is the maximum junction temperature during continuous 5A operation?

At 5A per leg and TC = 100°C, junction temperature reaches 130°C (TJ = TC + (IO² × RθJC × θ)). With RθJC = 3 K/W and IO = 5A, power dissipation is ~1.875W per leg, yielding TJ ≈ 105.6°C-well within the -55°C to +150°C operating range.

Does the common cathode connection support parallel operation of both legs?

Yes. Pins 1 and 3 are isolated anodes; Pin 2 is the shared cathode. Connecting both anodes to separate AC sources or using one anode as input and the other as freewheeling path is supported. Parallel use doubles current capacity but requires matched thermal paths to avoid current imbalance.

How does the guard ring affect layout requirements?

The guard ring improves edge termination robustness but does not relax layout rules. Maintain ≥2.5 mm creepage/clearance between anode traces and grounded heatsink, and avoid solder mask over the die area. No special PCB cutouts or guard traces are required beyond standard 60V isolation practices.
