MBR2045CTH

Diode Arrays Overview

The MBR2045CTH 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-220FP package with three leads. The device supports an average forward current of 10 amperes per diode leg and a peak repetitive reverse voltage of 45 volts. Key electrical characteristics include a maximum forward voltage of 570 millivolts at 10 amperes and a low reverse leakage current of 100 microamperes. It operates within a junction temperature range of -65°C to +175°C and withstands a non-repetitive peak forward surge current of 150 amperes.

Diode Arrays Procurement Notes

Verify the specific suffix 'H' against official onsemi documentation, as standard listings often reference the 'G' suffix for lead-free compliance. Confirm RoHS status and exact package dimensions directly from the manufacturer's datasheet before integration. Ensure the component meets all environmental regulations required for your target market.

Diode Arrays Selection Notes

Select this component for designs requiring low forward voltage drop and high thermal performance in compact through-hole layouts. The dual common cathode structure simplifies circuit design for synchronous rectification or bridge configurations. Evaluate thermal management requirements given the 175°C junction rating and ensure adequate heat sinking for continuous high-current operation.

Diode Arrays Part Context

This part belongs to onsemi's SWITCHMODE Power Rectifier family, which utilizes Schottky barrier technology for superior switching speed and lower conduction losses compared to standard PN junction rectifiers. The series is engineered for general-purpose power supply applications where efficiency and reliability are critical parameters.

Diode Arrays Replacement Considerations

Cross-reference with MBR2045CTG for identical electrical specifications and pinout compatibility. Verify that any substitute maintains the same TO-220FP package footprint and thermal characteristics to ensure seamless mechanical integration without PCB redesign.
