MBR2045CT

Diode Arrays Overview

The Vishay MBR2045CT is a silicon Schottky barrier rectifier featuring a dual common cathode configuration housed in a TO-220AB package. It supports a repetitive reverse voltage of 45 V and an average forward current of 20 A per element. The device exhibits a maximum forward voltage drop of 840 mV at 10 A and handles a non-repetitive peak surge current of 1060 A. Operating temperatures range from -65 °C to +150 °C junction temperature, with low leakage current characteristics suitable for high-efficiency power conversion.

• Polarity protection in low voltage systems
• High frequency inverters and power supplies

Diode Arrays Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm lead-free status and packaging variations. Confirm RoHS compliance details as regulatory standards evolve. Check for obsolescence notices or lifecycle changes directly from Vishay documentation before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a dual common cathode topology is required for synchronous rectification or free-wheeling duties. Ensure the 45 V rating exceeds the circuit's peak inverse voltage. Verify thermal management requirements given the 20 A continuous current rating and the thermal resistance inherent to the TO-220AB package under load conditions.

Diode Arrays Part Context

This part belongs to Vishay's MBR series of Schottky barrier rectifiers designed for general-purpose power applications. The series emphasizes low power loss and high reliability. The MBR2045CT specifically targets applications requiring higher current handling than single-element packages while maintaining low forward voltage characteristics typical of silicon Schottky technology.

Diode Arrays Replacement Considerations

Cross-reference with MBRB2045CT for surface mount equivalents. Verify electrical parameters against MBR2045CTe3/TU from Microchip Technology. Ensure pinout compatibility and thermal performance match the original design specifications when substituting.
