MBR1550CT

Diode Arrays Overview

The MBR1550CT is a silicon Schottky barrier rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a dual common cathode configuration housed in a TO-220-3 through-hole package. The device supports a continuous forward current of 15 A and withstands a repetitive peak reverse voltage of 50 V. Key electrical characteristics include a maximum forward voltage of 820 mV at rated current and a low reverse leakage current of 200 µA. It offers a high non-repetitive peak forward surge current capability of 200 A and operates within a junction temperature range of -65 °C to +150 °C.

Diode Arrays Feature Summary

• Incorporates a guardring structure to provide protection against overvoltage conditions.
• Features plastic packaging with Underwriters Laboratories flammability classification of 94V-0.

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free wheeling diode circuits
• Polarity protection applications

Diode Arrays Procurement Notes

Verify the specific manufacturer source, as historical data indicates production by GE before acquisition by onsemi. Confirm RoHS compliance status and REACH SVHC declarations via the official datasheet or component attributes page. Ensure the ordering suffix matches the required environmental specifications. Cross-reference the package type and pinout to confirm compatibility with existing PCB footprints before finalizing procurement.

Diode Arrays Selection Notes

Select this component for designs requiring a robust through-hole Schottky rectifier with a 50 V rating and 15 A continuous current capacity. The TO-220-3 package provides adequate thermal dissipation for moderate power levels. Consider the 820 mV forward voltage drop when calculating total system efficiency. Verify that the 200 A surge current rating meets the inrush requirements of the target circuit load.

Diode Arrays Part Context

This device belongs to the MBR series of Schottky barrier rectifiers, which are optimized for switch-mode power supplies and freewheeling applications. The 'CT' suffix denotes the dual common cathode configuration, allowing for use in full-wave rectification or push-pull topologies without requiring external wiring of separate diodes. The series is characterized by fast switching speeds and minimal reverse recovery charge.

Diode Arrays Replacement Considerations

Compatible substitutes include the MBR1545CT (45 V rating) and MBR1560CT (60 V rating) from the same family, provided voltage margins are adjusted accordingly. Other manufacturers offer equivalent 15 A, 50 V dual Schottky rectifiers in TO-220-3 packages, but pinout and thermal resistance values must be verified against the original datasheet.
