MBR1545CT802HE3/45

Diode Arrays Overview

The MBR1545CT802HE3/45 is a dual common-cathode Schottky rectifier manufactured by Vishay Semiconductors. It utilizes silicon technology and is housed in a D2PAK-3 (TO-263-3) surface-mount package. Key electrical parameters include a forward current of 15 A, a repetitive reverse voltage of 45 V, and a maximum forward voltage of 840 mV. The device supports a forward surge current of 690 A and operates within a temperature range of -65 °C to +150 °C.

Diode Arrays Feature Summary

• Dual common-cathode configuration for efficient rectification
• Guardring structure provides overvoltage protection
• Low forward voltage drop for high efficiency
• High forward surge current capability

Diode Arrays Applications

• Switching mode power supplies
• DC-to-DC converters
• Polarity protection circuits

Diode Arrays Procurement Notes

Verify the specific suffix HE3/45 against official Vishay documentation to confirm compliance with RoHS directives and halogen-free status. Confirm the package type matches the required PCB footprint. Check for end-of-life notifications or obsolescence notices from the manufacturer before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component for applications requiring a 15 A continuous current rating with a 45 V blocking voltage in a surface-mount format. Ensure the thermal management design accommodates the D2PAK-3 package's heat dissipation characteristics. Verify that the circuit's peak inverse voltage requirements do not exceed the 45 V rating under all operating conditions.

Diode Arrays Part Context

This part belongs to the MBRB15xxCT series of dual common-cathode Schottky rectifiers. It shares functional similarities with other Vishay Schottky diodes but is distinct due to its specific current, voltage, and package combination. The series is designed for low-loss, high-efficiency rectification in modern electronic systems.
